Yes, You Can Plant Trees in the Fall!

September 16, 2020

The days are getting shorter, and some mornings have a definite chill in the air. With fall closing in fast, many folks are winding down garden planting. We may think of spring as the traditional time to plant trees, but that's not necessarily true. In most of Maine, there are still PLENTY of growing days yet. Trees love the cooler weather in which to put down roots. In colder locations, fall planting can be risky.

The Maine Forest Service recommends early fall planting for most of Maine: When planting trees in the fall, the general rule is to plant them by Indigenous Peoples Day to give the roots time to establish before the ground freezes, and the cold weather shuts down growth. Tree roots need soil temperatures of at least 55 (at a 6-inch depth) and take approximately six weeks to get established. Just like planting trees at any other time of the year, be sure to mulch well (this helps to keep the soil warmer longer) and water well until the ground freezes. Dont prune your newly planted tree, or youll encourage top growth instead of where its needed at the roots.

Some trees do better than others when planted at the growing season's end. In general, plants with shallow, fibrous root systems do better with fall planting than those with a deep taproot. "Planting trees in early September provides enough time for root growth and establishment at the new site before soil temperatures drop and trees enter their dormancy period. This prepares trees for a head start on vigorous growth in the spring," says Maine Forest Service Forest Pathologist Aaron Bergdahl.

Whatever time you decide to plant trees in your yard, make sure you put the "right tree in the right place." Trees that grow 80-100 tall dont belong under power lines, and, likely, a weeping willow or river birch wont be happy in that hot, dry corner of your yard.

When choosing what type of tree to plant, look into whether the tree is likely to become a problem in natural areas in the future by consulting the advisory list from the Maine Natural Areas program. Be aware there are some species on the advisory list that are also illegal to import, export, buy, sell or intentionally propagate such as Norway and amur maple, tree-of-heaven and princesstree. The ban includes all cultivars, varieties and hybrids of these plants.

Be sure to research what will be needed to maintain the tree in the landscape. Some trees, such as true ashes (Fraxinus spp.), will require frequent insecticide treatments as emerald ash borer spreads. The Maine Forest Service cautions to avoid planting green, white and black/brown ashes. Several sites have excellent information that sums up some of these considerations for different species. If you dont find the information on the species you wish to plant, ask our experts.

Trees are an easy and inexpensive way to save energy, clean your air and water, increase your property value and improve your and your family's well-being. Properly planting the right tree in the right place can bring you decades of enjoyment.

Emerald Ash Borer Detections in Oakland and Waterville Provide Timely Reminder: Leave your Firewood at Home

June 30, 2022

For more information contact: Jim Britt at: Jim.Britt@maine.gov

Department reminds everyone to use local or heat treated firewood and announces Emergency Order expansion to slow the spread of emerald ash borer.

AUGUSTA - The Department of Agriculture, Conservation and Forestry's (DACF) Maine Forest Service (MFS) has expanded an Emergency Order to restrict the movement of ash from areas likely to harbor emerald ash borer (EAB). This order is in response to detections in Oakland, Waterville and Lewiston this month and earlier finds in Lovell and Gray and is in addition to the state quarantine rule on EAB. The order and the quarantine exist to help slow the spread of EAB within Maine.

EAB is a shiny green beetle killing ash trees in Maine and many other parts of North America. In the case of the Kennebec County detection, a chance sighting of bright spots on ash bark at highway speed on I-95 led to follow-up surveys on the ground confirming the beetles presence. In Lewiston, a crew examining declining ash viewed from the highway found emerald ash borer galleries in nearby trees. Although the detections are new, in at least one of the sites, the infestation has been developing for several years.

"These detections are a good reminder to leave your firewood at home and use local or heat-treated firewood," said State Entomologist Allison Kanoti. "In the case of the detection in Oakland, we can tell by evidence in the trees that the EAB has been lurking there for several years. Emerald ash borer is one of many insects and diseases that pose new threats to our trees, forests, environment, and economy. Many others can also hide in or on firewood and be transported to new places when we move firewood."

Ash is an important cultural resource for the Wabanaki, an important street tree and a valuable timber species, accounting for around four percent of Maine's hardwood forest inventory. EAB threatens all ash tree species (excluding mountain-ash) and will have significant ecological and economic impacts on the state. Although pesticide treatments can protect individual trees, and biological control provides long-term hope for keeping ash as part of our forests, there are no practical means to control EAB in forested areas.

What can I do to help slow the spread of EAB?

About the Emergency Order

What does the order do? The order limits the movement of ash trees for planting and ash tree products such as logs, pulpwood, green lumber, and hardwood firewood from the order area.

What is the order area? The order area covers Auburn, Durham, Greene, Lewiston, Lisbon, Mechanic Falls, Minot, Poland, Sabattus, Turner, and Wales in Androscoggin County; Albion, Belgrade, Benton, China, Clinton, Litchfield, Oakland, Rome, Sidney, Vassalboro, Waterville, and Winslow in Kennebec County; Albany Twp, Batchelders Grant Twp, Lovell, Mason Twp, Norway, Otisfield, Oxford, Stoneham, Stow, Sweden, and Waterford in Oxford County; Bowdoin and Topsham in Sagadahoc County and Fairfield, Norridgewock, Skowhegan, and Smithfield in Somerset County. This order area is in addition to areas described in the existing state quarantine, Maine DACF, Agriculture Rules, Chapter 275, which includes areas in Maine and other states and Canada.

If I'm only moving ash tree products within the order or quarantine area, do I need to worry about spreading EAB? EAB is not found everywhere within the order and quarantine areas. The MFS and our partners concerned with the future of ash trees in Maine encourage those involved in moving ash tree material within the regulated areas to follow Best Management Practices to reduce the spread of EAB.

What is the best practice for firewood for my next outdoor recreation trip?

The next time you head out to camp, fish, canoe, kayak, four-wheel, and otherwise enjoy the outdoors, follow these firewood tips.

  • Leave your firewood at home.
  • Buy firewood as close to your destination as possible.
    • Purchasing certified firewood is the best choice. Buy firewood with a state seal stating the wood has been heat-treated to 160 degrees Fahrenheit for at least 75 minutes.
    • Be sure to inspect the outside of packages of heat-treated firewood for pests that might hitch a ride after treatment (for example, look for browntail moth cocoons, spongy moth pupae, and spotted lanternfly eggs).
    • If certified firewood is not available, purchase your firewood as close as possible to where you will burn it.
    • At some sites, you may be able to gather firewood on or near the site. Check local rules.
    • Some sites, such as Baxter State Park, prohibit firewood from outside regardless of treatment status.
  • If youve already transported firewood, dont leave it or bring it home - burn it!
    • Be sure also to burn any small pieces of bark and debris that have fallen from the wood.
    • If you can't burn it all within 24 hours, follow firewood disposal and drop-off directions.
  • If the wood you find locally is not heat-treated and you don't burn it all, don't take it home with you or to your next destination.

More information on EAB can be found on the department's EAB website.

Tools and Tips for Helping To Knock Out More Browntail Moths

February 1, 2023

For more information contact: Jim Britt at: Jim.Britt@maine.gov

AUGUSTA, Maine - To draw increased attention to the risks presented to humans by the browntail moth (BTM), the Department of Agriculture, Conservation and Forestry announced February as Browntail Moth Awareness Month. Winter is the best time to spot, clip and destroy the caterpillars lying dormant in their winter webs. Web removal prevents more caterpillars from emerging, thus reducing the risk of toxic hairs, which can cause poison ivy-like rash and asthma-like reactions in humans. BTM has been in an outbreak phase since 2015, and the rash- and itch-causing pest cannot be eradicated. Comprehensive BTM tools and tips and data-informed resources compiled by the Maine Forest Service, Board of Pesticides Control, Maine Center for Disease Control, the University of Maine, and other partners, including research, infestation tracking, FAQs, and educational materials for communities, municipalities, businesses, and healthcare providers, are available on maine.gov/dacf/knockoutbtm.

Three Steps to Maximize the Effectiveness of BTM Awareness Month

Step One - Know the Four Rs to Reduce BTM populations in Maine

Recognize BTM winter webs in the trees where you live, work, or play. Knowing where BTM winter webs are in your yard or town can help inform your management decisions and aid in removal to prevent impacts from the toxic hairs.

Remove BTM webs with hand snips or an extendable pole pruner in areas within reach of the ground and away from hazards such as powerlines. Protect your eyes and skin from hairs that might be present from past caterpillar activity. After removal, destroy the webs.

Recruit professional help to treat BTM webs out of reach or near hazards on the property you own or manage. Licensed professional arborists can remove BTM webs in larger trees and shrubs in the winter. Some arborists offer web-clipping services using drones. Licensed pesticide applicators may be able to help control BTM adult breeding activities during the growing season.

Reach out if you have concerns about BTM. Neighbors, business owners, and community members can come together to respond to the problem and achieve greater results. Consider hosting your own BTM web clipping event in your neighborhood to reduce the itch for your family and your community!

Step Two: Participate and Share BTM Awareness Month Events

Participating in BTM knowledge-building activities and events can help you become more informed about BTM and bolster the momentum and energy needed to organize community web clipping or BTM mapping events. The following list is a sample of events and activities across the state.

February 2, 2023, 10:30 to 11:00 AM
Free and virtual webinar hosted by the Maine Forest Service Topics include BTM history, defoliation status, and tools to knock out BTM.

February 2, 2023, 3:30 to 4:30 PM
Free and virtual webinar hosted by the University of Maine One Health Initiative Topics include the University of Maine's BTM research. No registration is required; join by using this Zoom link. Passcode: 269053.

February 8, 2023, 6:30 to 8:15 PM

Free and virtual webinar hosted by Southern Maine Volkssport Association Topics include BTM biology, history, life cycle, status, management, and mitigation strategies. Pre-registration is required by emailing walkinginmaine@yahoo.com.

February 18, 2023, 10:30 to 12:00 PM
Free and in-person workshop hosted by the Androscoggin Soil and Water Conservation District and the University of Maine Cooperative Extension
Topics include hands-on learning about how to recognize and remove BTM. This workshop is an outdoor event; weather-appropriate attire is required. Bring pruning equipment and work gloves. Pole saws, hand saws, and loppers will be available for participant trials. More information and to register for the event can be found on their Events page. Registration is requested but not required.

Step Three: Always be learning about invasive pests threatening Maine's trees and forests.

Visit the Maine Forest Service webpage, explore the resources, and subscribe to news bulletin topics. During BTM Awareness Month, review and share news and events, FAQs, and management techniques. Test the BTM interactive map and read the latest research. For business owners, municipal leaders, and arborists, Maine Forest Service strongly encourages using BTM-specific resources for towns and businesses.

DACF Proposes Expansion of Quarantines to Slow the Spread of Three Tree Killing Invasive Species

August 21, 2023

For more information contact: Gary Fish at: gary.fish@maine.gov

The Maine Department of Agriculture, Conservation, and Forestry proposes expanding three forest protection quarantines to slow the spread of emerald ash borer, hemlock woolly adelgid, and European larch canker. Opportunities for public comment include public hearings at two sites and through a virtual option on September 6, 2023, at 10:00 AM, at the Maine Forest Service, Bolton Hill Regional Office, 2870 N Belfast Ave, Augusta, ME, and at the same time at the Maine Forest Service Regional Office, 87 Airport Rd, Old Town, ME. A virtual option using the Microsoft Teams platform will be available during those hearings. Commenters can join using this link, join the meeting on Microsoft Teams or by calling 207-209-4724 and the Conference ID of 429646377#.

The proposed changes to the emerald ash borer quarantine, Chapter 275, are designed to protect Maine's forest and timber resources to slow movement of the emerald ash borer to uninfested parts of the State. The proposal extends the quarantined area in the Northern Aroostook County area and into multiple new counties in southern Maine. These measures help protect over 60% of the ash resource that is still outside the current quarantine areas of Maine. Chapter 275 Proposed Rules Draft (DOCX) / Proposed EAB Quarantine Expansion Map (PDF)

The adjustments to the European larch canker quarantine, Chapter 272, extend a state quarantine against the European larch canker to prevent its movement from Hancock, Knox, Lincoln, Sagadahoc, and Waldo Counties and parts of Androscoggin, Cumberland, Penobscot, and Washington counties to other parts of the State to protect Maine's forest and landscape tree resources. The European larch canker is federally regulated, and this rule fulfills the requirement that Maine must have a similar state quarantine in place because the state is partially regulated for European larch canker. Chapter 272 Proposed Rules Draft (PDF) / Proposed ELC Quarantine Expansion Map (PDF)

The suggested changes to the hemlock woolly adelgid quarantine, Chapter 266, modify the existing hemlock woolly adelgid (HWA) quarantine by extending it to additional counties and Minor Civil Divisions in southern Maine. This expansion is needed because HWA populations were discovered outside the existing quarantine area. Chapter 266 Proposed Rules Draft (PDF) / Proposed HWA Quarantine Expansion Map (PDF)

Hallowell's Historic Horticulture

The Hallowell Tree Board (HTB), the Hallowell Conservation Commission (HCC), and the City of Hallowell are collaborating to restore the natural ecology at the Granite City Park (GCP) along the shoreline of the Kennebec River. The success of the restoration depends on educating the public, and planting and maintaining native trees and shrubs to replace the invasive Japanese Knotweed, Norway Maples and Multiflora Roses that have infested the area.

The HTB has a long history of improving the community forests and the urban natural environment. Over the last twenty years, over 200 trees have been planted, two gateways into Hallowell were established, public trees have been mapped, trees have been pruned and mulched, and a forest management plan for the 165-acre town forest was presented to the city council. The Tree Board has also collaborated with HCC on projects such as trail planning, brown tail moth control, and invasive weed control at selected sites.

The Granite City Park has been continuously improved over the past 20 years with the cooperation of the City and community organizations. In June 2008, the City of Hallowell financed and finished the construction of a boardwalk on the waterfront and set the stage for the new Granite City Park. The centerpiece of the park is a historic restored crane salvaged from the granite quarries which provided construction granite for the Maine State Capitol and numerous other private and public buildings in major American cities. Prior to the 2014 installation of the crane, the Tree Board planted a shad bush which is now part of the park. In 2019, the Hallowell Conservation Committee, with assistance from the City and community volunteers, planted an attractive three season pollinator garden designed to please the eye of the visitor and provide a food source for beneficial insects. In 2020, the Tree Board planted a sugar maple and the Hallowell Board of Trade donated an ornamental cherry. Both complement the area near to the flower garden.

The 2021 Project Canopy Grant has transformed the area and dramatically increased the usable space and attractiveness of the park. The result has received unanimous appreciation from the public, for land that was inaccessible and hidden in a forest of knotweed. This highly visible project has heightened public awareness of the importance of native forests and plants to rivers and community. The project provided resources to support ongoing partnerships among local groups to actively manage trees and shrubs. The experience of planting and seeing the transformation of the landscape with native trees and shrubs is very encouraging to our team of volunteers and the public at large.

This 2023 Project Canopy Grant is to continue our successful efforts with increased education efforts, the installation of an informational kiosk describing the restoration project, and additional plantings. The Hallowell Project Canopy Planning and Education grant proposal will leverage our work at the park into an educational opportunity for the community. We will continue our restoration project while informing and educating the community about why and how the ecosystem is recovering through the planting of trees, shrubs and ground covers. The foundation of our educational component includes the continued planting and knotweed cut back to restoring the site and educate the public as progress is demonstrated.

The project is in a highly visible urban area and provides an excellent opportunity for public education regarding the value of the diversified native ecology including trees, shrubs, and ground over to protect water and support a vibrant ecosystem.

We understand that this effort will need to be sustained for several years and we are confident that we can call on community, HTB, and HCC volunteers who have demonstrated a willingness to share in the responsibility and labor required to maintain these natural assets for the City.

What can you do now to reduce browntail moth next year?

December 13, 2023

Young browntail caterpillars create their winter webs in the summer and early fall by combining leaves together with white silk. During the winter, browntail caterpillars are dormant and rest inside their webs where they are protected from the harsh weather. These webs are usually at the tips of branches of their favorite host trees: oak, fruit trees (including ornamental varieties), black cherry, elm, birch, shadbush, roses, and others.

Pictured: Browntail webs are only a few inches long; about the size of the palm of your hand (left). Winter webs have white silk that can stand out on sunny days (right).

What can you do now to reduce browntail moth next year?

Winter is the best time to check your property for winter webs created by browntail. If you do have winter webs in your trees, follow the 4 Rs to Knockout Browntail:

  • Recognize winter webs. On a sunny winter day, stand with your back to the sun and look at your trees. Because their winter webs are made with silk, the webs will reflect the sunlight and be easier to spot. Consider focusing on trees in high traffic areas (i.e. closest to your house or areas of recreation).
  • Remove winter webs before April. Each winter web can contain 25-400 caterpillars; removing winter webs in high traffic areas (like your dooryard) can help reduce the browntail caterpillars that will emerge next year. Webs can be removed using pruning shears or an extendable pole pruner. Removal is recommended during the winter, when the webs are easiest to see, but before they emerge from their webs in April.
    • Destroy webs after removal by soaking them in a bucket of soapy water for a few days, or burning them in a safely contained fire to kill caterpillars inside the webs. Clipped webs that remain on the ground outside still contain live caterpillars that will emerge in the spring and climb back up the host tree.
  • Recruit professionals when you can't remove winter webs. Some webs found in tall trees may only be removed by a licensed professional. Check out our list of licensed arborists or our list of FAA-certified commercial remote pilots who offer browntail web removal in tall trees using unmanned aerial vehicles.
  • Reach out and educate others on the benefits of removal. The more browntail webs that are removed, the more likely it is that impacts may be reduced. Consider hosting a clipping party to remove winter webs in your neighborhood!

Should I consider using pesticides to treat browntail moth?

Pesticides may be considered for trees around your house or backyard when winter web removal is not possible. Pesticide treatments are most effective at reducing harmful impacts from browntail when they are applied by a licensed professional in the spring and the treatments will take effect before the end of May.

Winter is a great time to reach out to pesticide applicators to assess trees on your property and set up an appointment for pesticide treatment in spring. We have compiled a list of local licensed pesticide applicators for hire that are willing to treat browntail moth. Please note that these companies responded to a Maine Forest Service survey and agreed to be listed in this resource; the Maine Forest Service does not recommend these companies above any others.

Responsible Storm Cleanup Advisory

January 10, 2024

For more information contact: Jim Britt at: Jim.Britt@maine.gov

Augusta, ME (Wednesday, January 10, 2024) - In the aftermath of severe weather, residents across Maine come together to restore power, clear debris, and get their lives back to normal. While safety and recovery are top priorities, it's crucial to remember that everyone involved in storm cleanup can play a vital role in keeping Maine's forests healthy and resilient.

After power and other utilities have been restored, property owners often face the challenge of what to do with storm-damaged trees. To assist with this, Project Canopy, a Maine Department of Agriculture, Conservation and Forestry (DACF) and Maine Forest Service (MFS) program, offers valuable guidance and helpful tips to property owners with questions about handling downed trees, limbs, and branches.

Trees and Branches Around Homes and Power Lines:

  • Homeowners are encouraged to promptly address downed trees and branches, especially those affecting homes and power lines.
  • For trees entangled with power lines, it is essential to contact local power companies for assistance. Even if a fallen limb is not near power or utility wires, it's advisable to rely on professionals to assess the extent of the damage before attempting repairs or removal.
  • For trees or large branches threatening or impacting homes or businesses, enlist the help of a reputable licensed arborist to take care of cleanup.

Injured Trees Requiring Climbing or Chainsaw Work:

-In cases where storm-damaged trees require climbing or chainsaw work, homeowners are urged to work with licensed arborists. Arborists in Maine are required to be licensed. A license indicates that an individual is properly trained, has passed exams, and holds the required insurance. Arborists are trained tree care professionals with the skills to evaluate and rectify storm-damaged trees. They can determine how much of a tree can or should be salvaged.
- Beware of fly-by-night emergency tree-cutting services, and always request proof of licensing, insurance, and references. The DACF Division of Animal and Plant Health Arborist Program provides more information about working with arborists.

Protecting Maine's Forests

The Maine Forest Service stresses that woody debris from storm damage may harbor harmful insects or diseases that threaten our forests. Transporting this debris over long distances, greater than ten miles, can unintentionally spread pests to new areas.

  • In addition to the risks it brings to our environment and economy, violation of rules governing debris movement jeopardizes eligibility for federal aid in the event of a disaster declaration.
  • Please be aware of quarantine regulations that may impact the movement of some woody storm debris, such as ash trees within the Emerald Ash Borer Regulated Area, larch from areas within the European Larch Canker quarantine, and hemlock branch or top material from regions within the Hemlock Woolly Adelgid quarantine.
  • Severe storms can also reveal the presence of invasive forest pests like the Asian longhorned beetle or hemlock woolly adelgid. If you suspect damage from such pests, take photos and share them with the MFS to aid in pest management efforts.

Storm Preparedness Resources

In addition to responsible storm cleanup, being prepared for future storms is vital. Here are some resources to help you stay informed and ready:

Department of Agriculture, Conservation and Forestry's Maine Forest Service Secures Community Wildfire Defense Grants for Northern and Downeast Maine

May 24, 2024

For more information contact: Forest Ranger Specialist Kent Nelson at: kent.nelson@maine.gov

Augusta, Maine - The Department of Agriculture, Conservation and Forestry's (DACF) Maine Forest Service (MFS) has been awarded two Community Wildfire Defense Grants (CWDG) to support at-risk communities in Northern and Downeast Maine. These grants, totaling $258,000 ($141,000 and $117,000, respectively), will safeguard homes, businesses, forestland, and infrastructure from catastrophic wildfires. Both regions face significant wildfire risks and are considered underserved.

Federal funding will facilitate the creation of Community Wildfire Protection Plans (CWPPs) over five years. Last fall, the USDA Forest Service received 535 applications, awarding grants to only 158 communities nationwide. Maine is New England's first and only state to receive these highly competitive CWDG awards.

MFS will lead the development of CWPPs, coordinate data collection, and engage stakeholders and the public. These plans will evaluate wildfire risks, inventory access routes, utility corridors, and other critical assets and foster collaboration between local governments, fire departments, state agencies, the Maine Land Use Planning Commission (LUPC), and other key stakeholders.

"Earning these federal grants is a significant accomplishment for our Maine Forest Service. Given the competitive nature of these grants, typically awarded to western states, we are incredibly proud that Maine is the first New England state to be awarded these funds," said Amanda Beal, DACF Commissioner.
"As the most heavily forested state with a history of rural wildfires, it is crucial to prioritize wildfire risk mitigation. This federal funding will enhance our efforts to protect communities and ensure their safety from wildfires," said Patty Cormier, MFS Director.
"We are thrilled to receive the CWDG grants and are eager to collaborate with County Emergency Management Agency directors, Fire Chiefs, and large forest landowners to mitigate wildfire risks and bolster the resilience of our forests," said Robby Gross, Chief Forest Ranger.

The Northern Maine / Katahdin Region grant encompasses Millinocket, East Millinocket, Medway, and several adjacent unorganized territories. This project area borders the Katahdin Woods and Waters National Monument and is near Baxter State Park, home to Maine's highest peaks. The Downeast Maine grant includes the towns of Whiting and Dennysville and four unorganized territories in Southeast Washington County.

Communities interested in applying for the next round of CWDG grants, which is expected to be available later in 2024, should contact Forest Ranger Specialist Kent Nelson (207) 287-4989, kent.nelson@maine.gov.

Summer Outdoor Activities and Invasive Species: Protect Maine's Forests

July 3, 2024

For more information contact: Jim Britt at: Jim.Britt@maine.gov

Augusta, Maine - Mainers and visitors are eager to enjoy camping, hiking, and other outdoor recreational activities as summer unfolds. However, these treasured pastimes have a hidden threat: the spread of tree-killing invasive plants, insects, and diseases that cause significant environmental damage.

The Maine Department of Agriculture, Conservation and Forestry's (DACF) Plant Health and Forest Health Divisions have joined forces to launch the "Protect Maine's Forests" awareness outreach campaign to combat this issue. This initiative aims to inform and educate outdoor enthusiasts on preventing the introduction and spread of invasive pests.

"Invasive plants, insects, and diseases often spread without our knowledge, significantly altering and affecting our forests and landscapes," said Gary Fish, Maine State Horticulturist. "While we can't control the natural spread of these species, such as by animals or the wind, we can reduce movement, particularly for those associated with outdoor recreation."

The campaign, which started in June, urges everyone who enjoys the outdoors to follow three critical steps when traveling to or leaving the woods:

  • Do not move firewood.
  • Check vehicles for hitchhiking pests.
  • Clean and dry gear thoroughly.

These precautions are crucial for preventing other invasive species, such as the Asian longhorned beetle and spotted lanternfly, from establishing in Maine. These pests have caused widespread plant and tree deaths in the US. The Asian longhorned beetle targets maple trees, while the spotted lanternfly feeds on trees and valuable crops like grapes and hops.

  • Buy Firewood Where You Burn It
    One of the most common ways invasive pests are spread is through the movement of firewood. Campers moving firewood distances greater than 10 miles within Maine or from other states can unknowingly introduce forest pests. To prevent the spread of these pests, buying or gathering firewood near where it will be burned or purchasing certified heat-treated firewood is crucial.
  • Avoid Hitchhikers
    A useful tip for all outdoor adventurers is to keep a brush in your vehicle. Use it to clean off boots, clothing, bicycles, and gear, especially items stored outdoors. This should be done before setting out on a trip and returning from the forest.
  • Keep Your Gear Clean
    Outdoor enthusiasts are encouraged to take simple but crucial steps to help protect our forests. Since invasive plant seeds and insects can lodge in dirt on boots, bike tires, and gear, it is vital to thoroughly clean all equipment before and after venturing outdoors. This practice helps prevent the dispersal of insects or their eggs to new areas, maintaining our natural landscapes' value, health, and beauty.

"Protecting our forest health is critical to maintaining the biodiversity and ecological balance that supports both wildlife and human communities," said Karen Coluzzi, an entomologist with DACF's Plant Health Division. "By monitoring and managing insect populations, we can prevent the spread of invasive species and ensure our forests remain resilient and vibrant for future generations."

If you've traveled to a state where the spotted lanternfly is established, Coluzzi recommends inspecting your vehicle and belongings before returning to Maine. Soon, adult lanternflies will emerge and can easily hitchhike in and on cars, trucks, boats, and plant material. As of June 2024, the spotted lanternfly has been found in 17 U.S. states, including Connecticut, Delaware, Illinois, Indiana, Kentucky, Maryland, Massachusetts, Michigan, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, Tennessee, Virginia, and West Virginia.

By following these guidelines, we can all help protect Maine's forests from the threat of invasive species. Let's work together to keep our natural landscapes healthy and thriving for future generations. Learn more about Maine's Invasive Plant Rules and the ban on moving firewood.

Maine's Forestry Community Champions Water Quality Protection During Timber Harvesting

August 1, 2024

For more information contact: Tom Gilbert, Water Resources Specialist at: thomas.gilbert@maine.gov

Augusta - The Department of Agriculture, Conservation and Forestry's Maine Forest Service (MFS) is happy to announce the results of its 2022-2023 study on the implementation and effectiveness of Best Management Practices (BMPs) in timber harvesting across the state. BMPs are voluntary measures designed to safeguard water quality, and their usage and effectiveness are rigorously monitored by MFS's 11 District Foresters and Water Resources Specialists. These monitoring results are reported biannually. The 2022-2023 results are consistent with previous years, showing a solid commitment to BMPs within Maine's forestry and logging community. Notably, there was a 5% decrease in sedimentation associated with crossing structures since the 2020-2021 report, reducing the total to 29%. Historically, sedimentation is most often linked to crossing structures, averaging 31% from 2005 to 2023.

"On behalf of the MFS, I thank Maine's forestry and logging community for its unwavering commitment to protecting our water resources," said MFS Director Patty Cormier. "Despite market disruptions, severe weather patterns, and workforce issues, loggers, foresters, and landowners have demonstrated resilience and dedication. The consistent use of BMPs showcases our collective responsibility towards safeguarding natural resources. This report highlights the significant progress made, and I'm confident we will continue to improve."

Key Findings from the 2022-2023 Report

  • 70% BMP Application on Crossings: Seventy percent of sites had BMPs correctly applied on crossings and approaches, or crossings were completely avoided. MFS BMPs emphasize planning harvests to minimize stream crossings whenever feasible.
  • 84% Effectiveness in Preventing Sedimentation: Eighty-four percent of BMP observations indicated that no sediment entered a waterbody, achieving the primary goal of BMPs to keep sediment out of water sources.
  • 97% Safety from Chemical Spills: Ninety-seven percent of sites showed no evidence of chemical spills, highlighting the importance of proper chemical storage, securing, and preparedness.
  • Effective Sediment Prevention: When properly applied, BMPs effectively prevent sedimentation. Sedimentation events were closely linked to inadequate BMP application or maintenance.
  • 97% Wetland Protection: Ninety-seven percent of sites had no wetland crossings, demonstrating effective BMP use or avoidance strategies.

Extensive studies and monitoring reports affirm that properly applied BMPs effectively protect water resources. Conversely, inadequate or improper BMP application significantly increases the risk of environmental harm. This reinforces the importance of continuous monitoring, education, and training to maintain and enhance BMP usage.

Help Protect Maine's Trees: Join the Fight Against Invasive Species this August

August 1, 2024

As we enter the peak season for invasive insect activity, the Maine Department of Agriculture, Conservation and Forestry (DACF) and the United States Department of Agriculture (USDA) call on everyone to help protect our beloved trees. Throughout August, we encourage everyone to spend just a few minutes checking the trees in their communities and forests for signs of invasive species.

Help Matters

Invasive species, which include non-native plants, animals, and diseases, can cause significant harm to our environment, economy, and even human health. These invaders can wreak havoc without natural predators or diseases to keep them in check.

Maine State Horticulturist Gary Fish explains, "Our first defense against invasive species is to prevent their arrival in the first place. Our partners at USDA APHIS and Customs and Border Protection here in the US and the Canadian Food Inspection Agency north of the border frequently stop plant pests before they can gain a foothold in North America. However, the volume of trade and travel prevents them from stopping every pest."
Maine State Forester Patty Cormier highlights the crucial role of public involvement: "Trees are vital to our state economy and provide countless environmental benefits, including clean air, water, wildlife habitat, and recreation opportunities. With more eyes on the ground, we can help detect invasive insects early, preventing tree loss and preserving our forests."

Spotting the Threats - What to Look For

Watch for four primary invasive species:

  • Asian longhorned beetle - This large (>1") black and white beetle has a taste for maples and other hardwood or broad-leaved trees. Look for oval to round wounds on the bark where the females have chewed out a site to deposit eggs, round holes in the trunks and branches of trees, and piles of coarse sawdust at the base of trees.
  • Emerald ash borer This small (<1/2") metallic green beetle is deadly for ash (Fraxinus) trees. Look for small (1/8") D-shaped adult exit holes in the bark, winding frass-filled (sawdust-like waste) feeding galleries under the bark, woodpecker feeding, crown dieback, and epicormic shoots. Emerald ash borer has been found in Parts of Androscoggin, Cumberland, Kennebec, Oxford, Penobscot, and York Counties in the southern half of the state and northern Aroostook County.
  • Oak wilt disease - This deadly fungal disease of oaks is found in other parts of the United States, including the closest known infestations in New York State. Look for leaves suddenly turning brown or dropping in the red oak group (pointed lobes on leaves) trees during summer months.
  • Spotted lanternfly - This colorful planthopper, not known to be established in Maine yet, is an expert hitchhiker with a broad appetite. Spotted lanternfly feeds on and can damage various plants. It is best known for its impact on grapes and hops. Look for the brightly colored nymphs and adults, but be aware that this insect hitches a ride most subtly as dull-colored egg masses. Like the infamous spongy moth, the adult lays eggs on almost anything.

For more detailed profiles on these and other threats, visit the Maine Forest Service website: maine.gov/forestpests.

What You Can Do

Please take 10 minutes and inspect the trees in our yards, neighborhoods, and local forests. If a suspected invasive pest is identified, take a picture and send it to foresthealth@maine.gov. Spotted lanternfly reports can be sent to bugwatch@maine.gov. Ensure photographs are detailed enough for verificationplacing a coin or pencil next to the pest for scale can be helpful. If possible, capture the insect in a rigid container and store it in a cool place until you receive a response.

Prevent the Spread

Taking a few simple actions can make a big difference:

  • Buy firewood where you'll burn it or gather it on-site if permitted. Moving firewood can spread invasive pests.
  • Check vehicles, bags, and boxes for insects when traveling locally or moving to a new area. Invasive insects can easily hitch a ride.

State Horticulturist Fish reminds us, "We all have a role to play in preventing the spread of invasive species. Taking a few minutes to check the trees in your yard can ensure that our forests and trees are here for future generations."

We appreciate everyones dedication to protecting Maines trees and forests. Your vigilance and action are invaluable.

Timber Harvesting Standards in Shoreland Areas to Change in Maine's Unorganized Territories in 2026

August 2, 2024

The Maine Department of Agriculture, Conservation and Forestry's Maine Forest Service (MFS) announced today that Maine's "statewide standards" for timber harvesting in shoreland areas will apply to unorganized territories starting January 2026, as per statutory requirements.

Established in 2005, the Statewide Standards for Timber Harvesting and Related Activities in Shoreland Areas (SWS, also known as Chapter 21 rules) apply only to organized towns that have adopted them through local ordinances. Unorganized territories follow a different set of rules (Chapter 27) under the MFS authority, delegated by the Land Use Planning Commission.

The statute establishing SWS stipulated they would become effective statewide, including in unorganized territories, once a "critical mass" of organized towns adopted them. With more than 260 towns adopting SWS, they will take effect in the unorganized territories in January 2026.

MFS is hosting a webinar to outline the implementation process for the statewide standards.

Date: Wednesday, August 7, 2024 Time: 9:00 AM (EDT)

Interested parties can register to attend the webinar here: Maine Forest Service Public Briefing: Statewide Standards for Timber Harvesting in Shoreland Areas.

Additionally, MFS will provide further information and numerous training opportunities for foresters, loggers, and landowners over the next 18 months. The Chapter 27 rules for unorganized territories will also be revised to eliminate duplication.

Visit the Maine Forest Service website for more information about the SWS implementation process and the rules. Questions can be directed to forestinfo@maine.gov or the MFS office at (207) 287-2791.

Thank You.

Red Pine Scale: 2024 Trapping Program Results

January 30, 2025

Overview

Red pine scale (Matsucoccus matsumurae), an invasive pest native to Asia, has been causing significant damage to red pine (Pinus resinosa) stands in Maine. First identified in the United States in Connecticut during the 1940s, this pest was later detected in Maine on Mount Desert Island in 2014. It feeds on the inner bark of red pine, which can lead to crown thinning, needle loss, and eventual tree mortality, though early infestations may be difficult to detect. Further information on the species can be found in our factsheet.

Images: (left) Infestation causes discoloration of red pine needles; (right) A severe red pine scale infestation can result in the eventual death of all red pine in a stand, leaving other species such as white pine unaffected.

In 2024, the Maine Forest Service piloted a new method of detecting the red pine scale using sticky traps. The program focused on sites in the Downeast region to evaluate the effectiveness of this technique in early detection and to identify new infestation sites.

Findings

The trapping program successfully detected red pine scale at several key locations. To confirm the species' identity, a subsample of the collected specimens was submitted to the University of Maine Cooperative Extension Diagnostic and Research Laboratory for genetic testing.

Known infested areas in T22 MD BPP, Columbia, and Osborn served as positive controls. Red pine scale crawlers were detected at all sites in these towns. Crawlers were also collected at three locations not previously known to have the scale, including sites in T30 MD BPP, T36 MD BPP, and southern Beddington.

The site in T36 MD BPP is notable due to its location in the Machias River Corridor on publicly owned land with a large amount of mature red pine. The relatively low number of crawlers collected, combined with the lack of obvious host symptoms, suggests an early-stage infestation.

These findings highlight the potential of sticky traps as an effective tool for early detection of red pine scale infestations, particularly in areas where visible symptoms have yet to emerge.

Next Steps

Land managers with commercially important red pine resource are encouraged to proactively monitor sites for signs and symptoms of red pine scale. These include settled scales underneath bark flakes on twigs, white fluffy material associated with some stages of the insects and a progression in color change of the needles from healthy green, to olive green, to brick red, and eventually gray. This progression can be quite rapid, so frequent visits to mature stands are recommended. Please report any suspected areas of infestation to our office.

Images: (left) The settled scales are small, flat, and white-fringed; (center) adult females are mobile and dark red; (right) male cocoons and female egg ovisacs are covered in a white cottony substance.

The Maine Forest Service will continue monitoring efforts. If you own or manage red pine outside of the areas with detections and are interested in volunteering to help, please reach out to foresthealth@maine.gov. We will be looking for sites to trap as well as looking for cooperators interested in conducting trapping in cooperation with our team.

Future findings will be shared via these newsletters, so please encourage others who may be interested in this information to subscribe!

Emerald Ash Borer Confirmed on Mount Desert Island

April 1, 2025

For more information contact: Jim Britt at: Jim.Britt@maine.gov

Maine Department of Agriculture, Conservation and Forestry Expands Emerald Ash Border Quarantine Area, Urges Vigilance and Informed Response

AUGUSTA, Maine - Maine State Forester Patty Cormier today announced that the Maine Forest Service (MFS) Forest Health and Monitoring Division has confirmed the presence of emerald ash borer (EAB) on Mount Desert Island (MDI) outside of the previously regulated area.

A licensed professional arborist in Bar Harbor made the detection. The infested area shows signs of a well-established EAB population, with visible damage to ash trees from public roads.

"This is an unfortunate but not entirely unexpected discovery," said Cormier. We've known that EAB continues to spread throughout Maine, and we appreciate the vigilance of local arborists and community members. Public awareness is important to detecting and responding to this destructive forest pest.

As a result of this detection, the Maine Department of Agriculture Conservation and Forestry will expand the current EAB quarantine to include all towns on MDI. This non-contiguous quarantine may help slow the spread.

Key guidance for landowners, municipalities, and the public includes:

  • Ash tree material should remain on MDI. Logs, branches, or wood waste from removed trees should be disposed of on-site or at an island-based disposal facility.
  • Ash chips are not regulated and may be legally transported off the island.
  • High-value ash trees that are not heavily infested can be evaluated and may be preserved through systemic insecticide treatment by licensed pesticide applicators. These treatments require periodic reapplication.
  • Infested ash trees will decline quickly and become structurally unstable. Property owners and managers are urged to evaluate ash trees near infrastructure for potential treatment or removal.

The MFS and collaborators, including the Ash Protection Collaboration Across Wabanakik's (APCAW), Sustaining Ash Partners Network (SAP-Ne), and USDA Animal and Plant Inspection Service, continue to support ongoing mitigation efforts, including:

  • Release of biological control organisms from federal partners by MFS through community partnerships.
  • Seed collection and protection for future restoration led by APCAW.
  • Education and technical support by varied partners.
  • Public tree management and replanting through state and federal funding opportunities.

    Emerald ash borer is one of the most damaging forest pests we face, added Cormier. By working together with awareness, early detection, and coordinated response we can slow its spread and protect Maine's forest resources.

Please let us know If you suspect you have found damage from EAB in Maine, refer to maine.gov/eab. This website features an interactive map with EAB detections, quarantine boundaries, and tools for identification and reporting.
