Red Squirrel use of Dwarf mistletoe-induced witches' brooms in Douglas-fir
Article Abstract:
Douglas-fir dwarf mistletoe (Arceuthobium douglasii) infections affect host trees by reducing growth and seed production and increasing mortality and can also form witches' brooms, which are profusely branched, dense masses of distorted host branches in the crowns of infected trees. The use of brooms in Douglas-fir (Pseudotsuga menziesii) in mixed-conifer forests in northern Arizona and New Mexico, USA were compared in 1998 and 1999 with the aim to determine whether red squirrels (Tamiasciurus hudsonicus) selected brooms for roosting and foraging, or caching sites.

Landscape models to predict the influence of forest structure on tassel-eared squirrel populations
Article Abstract:
Modeling effort to produce spatial data was undertaken to examine the results of proposed management actions on squirrel habitat. It resulted in spatially explicit models that were used in efforts to predict the effects of forest management on squirrel populations.

Tassel-eared squirrel population, habitat condition, and dietary relationships in north-central Arizona
Article Abstract:
Research indicates that thinning of Arizona's forest trees has a negative impact on tassel-eared squirrel populations, as it decreases the amount of fungi available as a food source for squirrels. Implications for forest management policies are discussed.
