Forest Type: Klamath mountain mixed conifer and mixed hardwood-conifer forests
Habitat Attribute: Shrub-herbaceous interspersion understory
Landscapes: Within 1,000 ha (2,500 ac) blocks, provide patch sizes according to the following forest cover amounts for high suitability habitat:
– >90% forest cover = >8 ha (20 ac) patch size
– >80% forest cover = >26 ha (64 ac) patch size
– >70% forest cover = >66 ha (163 ac) patch size –
– >60% forest cover = >156 ha (385 ac) patch size
– >50% forest cover = >353 ha (873 ac) patch size
Sites: Where ecologically appropriate, maintain an understory ratio of shrub-herbaceous (includes bare ground) cover within a range of 30–70% for each parameter.
Habitat Conservation Strategies
– Remove or explicitly control the timing and intensity of grazing to develop and promote the long-term persistence and balance of shrub and herbaceous communities.
– Promote understory growth through natural disturbance or management that breaks up the forest canopy yet still maintains the dominance of a mid- or late-successional forest.
– Where ecologically appropriate in drier mixed conifer forests, maintain large forest tracts (i.e., minimize fragmentation) for highly suitable habitat.
