Consolidating classes

Concepts:
   unique values grouping

Any unique values classification can be consolidated by grouping values together.  For example, if a simpler classification is desired, such as consolidating all forested classes together, those pixel values in the unique values classification can be grouped in ArcMap.   This does not change the source data at all, and is not a "reclass" (more on reclassing later).

Just click on the classes you want to group, right-click and choose 'Group Values'.
