Cumulative Effects:
The cumulative effects of implementing the action alternatives are that the existing system road
network would receive measurable improvement, with 0.8 miles of classified road being
converted to a trail following the harvest, 0.4 miles of classified road being decommissioned, and
travel being rerouted to FSR 118.2G. A beneficial impact will be a reduction in the amount of
on-going erosion and sediment input into streams and a 1/2 mile net reduction of open road
density within the Analysis Area. Changing segments of FSR 118.2 & FSR 118.2G to
Maintenance Level 3 would increase long-term maintenance costs on 1.7 miles, but would
further reduce sediment input into streams.
3.16 Recreation Travel Management
Scope of Analysis
The Rio de los Pinos Analysis Area boundary.
Past Actions that have affected the Existing Condition
Past activities that affect the existing conditions include livestock grazing, timber harvest, road
construction, and various forms of dispersed recreation, all within the Rios de los Pinos Analysis
Area boundary.
