2 Past, Present and Reasonably Foreseeable Future Actions This report summarizes the analysis area and the temporal scale (time) considered for the cumulative effects analysis. Each resource analysis has disclosed the specific cumulative effects for that particular resource area. Refer to the applicable EA sections for a specific discussion of cumulative effects. Scope of the Cumulative Effects Area The cumulative effects area would be at a minimum the project area. In addition, some resources would use a larger cumulative effects area such as subwatersheds. The time period used for including past actions is 30 years ( ) for federal actions and 20 years ( ) for private lands. Past, Present and Reasonably Foreseeable Future Actions The following list of cumulative effects actions is considered for this project. Maps showing these activities in relationship to the project area follow the tables. The tables summarize those past, and foreseeable future actions, with a description of the activity and the acres affected. Guidance on cumulative effects, in particular, past actions, was considered, based on Connaughton (2005), here by incorporated by reference. Table 1.
