Environmental Assessment

IMPLEMENTATION GUIDELINES CHAPTER 2
OG/LOS4-Prepare management plans for Old Growth Management Areas (completed November,
2004 for Pine Mountain and Pumice Springs OGMAs) in need of special treatment measures
(reference the LRMP Implementation Schedule, Appendix 15).
Special/Unique Habitats:
S/U1-Protect the ecotone areas where forested habitats are adjacent to cliffs, rock outcrops, springs,
forested lavas, lava tubes, and caves by providing a buffer where vegetation management
activities would occur. The buffer width will be determined on a site-by-site basis by operations
staff and the biologist, but generally it will range from 30 to 50 feet for rock outcrops to 300 feet
for caves (S&G WL-70, 75). This mitigation measure applies to the following Alternative 2
units: F 01 (sage, rock opening), 03 (forested lavas), 10 (rocky, low sage), 18 (cliffs), 22 (cliffs),
and 38 (sage, rock opening). Alternative 3 units: F03 (forest lavas, special coordination
needed), 04 (rocky, low sage), 09a (sage, rock opening), 18 (cliffs), and 38b (sage, rock opening).
Note: Refer to Tables A-5a, A-5b, A-6, and A-7 in the Appendix for unit specific mitigation and
implementation measures.
The following section is summarized from the Biological Evaluation in order to facilitate project
implementation.
Scenic Resources and Recreation (Common to Action Alternatives)
1. Consult with a Landscape Architect to establish unit layout and marking guides in foreground
treatment areas on Road 2017 and adjacent to recreation sites. Monitoring is to be completed by
a Landscape Architect within one to two years following completion of the proposed treatment
and mitigation activities.
2. Flush cut stumps and locate skid trails and landings beyond 300 feet of from Road 2017. Cleanup
activities in foreground treatment areas, recreation sites, and main travel routes, which include
landings, skid trails, and slash piles. Use a low impact machine or hand piling in recreation sites
and within 300 feet from the main roads such as Road 2017. Work should be completed within
two years after activity. Retain sufficient quantities of downed logs, snags, and other materials to
meet coarse woody debris, snag, and other resource requirements.
3. Avoid scorching above 2/3 of the live crown in prescribed burn units located within foreground
treatment areas (within 300 feet of Road 2017). Severely damaged or burned trees shall be
removed as part of post-treatment activities within two years.
4. Minimize ground disturbance and damage to vegetation in foreground treatment areas along main
travel routes and recreation sites. For larger or more heavily used dispersed camping sites, avoid
the immediate area within 100 feet of the center of the camping site and protect from prescribed
fire by placing a fire line around the perimeter of the site.
5. Design fuel and vegetation units to minimize ground disturbance and damage to vegetation in
foreground treatment areas along main travel routes in order to avoid further exposure of existing
livestock trails.
6. Remove safety hazards created from vegetation treatment such as “widow makers” and other
unsafe conditions beyond those needed to meet coarse woody debris and snag requirements.
