ALTERNATIVE DESCRIPTION – ALTERNATIVE – TREATMENTS CHAPTER 2 Roads To reduce habitat fragmentation and mitigate both the reduction of hiding cover and the low levels of thermal cover, approximately 42 miles of existing system roads would be either closed or decommissioned (Table 2-5) and Figures 2-3a-c). Approximately 28 miles of roads would be closed. Closed roads are not needed for current management, but are expected to be needed for future management activities. Closed roads could be used for administrative purposes (permit administration, fire suppression, etc.) or by permittees under permit such as for grazing. Approximately 14 miles of system roads would be decommissioned. Decommissioned roads are not needed for current or future management activities and are not used for administrative needs. Decommissioning involves removing the road from the transportation system and often includes subsoiling to make the road impassible to motorized vehicles. Four roads identified for decommissioning also provide access to grazing facilities or improvements – fences, water sets, or trend plots. These include 2300-080, 2017-400, 2017-540, and 2017-543. Segments providing access to those facilities or improvements would not be subsoiled until such time as the facilities or improvements were removed or access no longer required. Two roads, 2300-080 and 2017-400, in addition to providing access to water sets, fences and a trend plot, are also proposed for incorporation into a class II OHV designated trail under another project. Of the approximately 14 miles of system road proposed for decommissioning, approximately 10 miles would be subsoiled. Seasonal Administrative Closure (Alternative 3) Seasonal closures on roads and motorized trails would be implemented between December 1 and March 31 of the following year after the vegetation and fuel reduction treatments to mitigate the effects and reduce the harassment of wildlife, particularly deer, during critical winter months. The closure would be implemented in areas impacted by management activities including both timber harvest and fuel reduction treatments. It would not be applied to designated trails within the East Fort Rock OHV area. All roads, except those listed in Table 2-4, would be closed to motorized use during this period. Closures would be implemented upon completion of vegetation and fuel treatment activities in those areas. This would reduce road densities to or below the 2.5 mile per square mile density prescribed in the LRMP for mule deer winter range (S&G M7-22, LRMP page 4-115).

No road reconstruction would be required on existing system roads. Thirty-seven (37) miles of system roads would have maintenance performed prior to commercial harvest activities to bring them up to standard for log haul. See previous discussion for Alternative 2, Table 2-2 for specific roads.
