TABLE A-2 - SNAG DENSITIES BY PROPOSED HARVEST UNIT AND OVERALL 



In all proposed harvest units, the remaining 

 snag density meets ARM 36. 1 1.411(a). The 

 proposed harvesting of snags would result in 

 decreased foraging and nesting sites for 

 wildlife species. However, the proposed 

 salvage is expected to maintain a diversity of 

 existing snags to provide habitat, albeit 

 reduced amounts, for snag-dependent 

 species. Some additional losses could occur 

 during harvesting; however, due to the 

 scattered distribution of trees and snags, 

 these losses are expected to be minimal. 

 The Forest Officer would be responsible for 

 keeping these losses to the absolute 

 minimum. 



In addition to salvaging snags, the proposed 

 harvests would include snag-recruitment 

 trees in the near future. Harvesting these 

 trees is expected to slow infection to other 

 susceptible trees in and around the proposed 

 stands. If effective, reduction in mortality of 

 large Douglas-fir and, to a lesser extent, other 

 species, would result in maintenance of 

 higher canopy closure and provide snag 

 recruitment in a steadier stream through time. 

 These situations are expected to provide 

 habitat for snag-associated species more 

 consistently over time. Additionally, the 

 slower mortality would allow more time for live 

 trees to grow and contribute to the canopy 

 closure and snag recruitment. However, 

 these trees would be primarily shade-tolerant 

 species. Followup harvests to promote 

 reproduction of shade-intolerant trees is 

 recommended in the future. 



The loss of feeding or reproduction habitat is 

 not expected to substantially affect wildlife 

 species in the area. The retention of snags, 

 nonmerchantable trees, and leave trees 



would continue to provide foraging sites. The 

 retained amount of snags is expected to meet 

 or exceed the densities expected historically 

 in the large and very large size classes. 

 Additionally, live large trees would be left on 

 site, which could provide snag and log 

 recruitment through time. Many small- to 

 medium-sized trees would be retained, 

 thereby providing a source for recruitment of 

 small- to medium-sized snags. Reductions in 

 small- and medium-sized snags would be 

 shorter lived, while large and very large 

 snags would be retained along with live trees 

 to provide recruitment for the future. 

 Although deadwood resources would be 

 reduced, deadwood retention levels and the 

 potential for future deadwood recruitment 

 would continue to provide adequate habitat in 

 the project area for native species that rely on 

 deadwood.

No additional disturbance to deadwood 

 habitat would occur. Other DNRC projects, 

 such as the Goat Squeezer Timber Sale 

 Project, would continue in nearby areas. 

 Douglas-fir bark beetle populations would 

 continue to cause mortality in and around the 

 project area. The increased tree mortality in 

 Douglas-fir would provide additional foraging 

 opportunities for wildlife species. The 

 mortality of these large trees reduces the 

 potential for heartrot infection. Unless the 

 affected tree was already infected with 

 heartrot, additional nesting trees and hollow 

 logs for use by wildlife species are not 

 expected. Additionally, continued increased 

 mortality would reduce snag and coarse 

 woody debris over the long term. The
