Title: Forest Management and the Dead Wood Resource in Ponderosa Pine Forests: Effects on Small Mammals
Author: Chambers, C.L.
Subject: Mammals, Understory, Ponderosa pine (Pinus ponderosa)
Abstract: Changes in vegetation structure and composition affect habitat for wildlife. Species such as small mammals that are restricted to small home ranges and are relatively immobile may be most affected since it is more difficult to find and move to new habitat. In the southwestern United States, forest management treatments (thinning and prescribed burning) are being implemented to alter structure and function of ponderosa pine (Pinus ponderosa) ecosystems and recreate pre-settlement (ca. 1870) tree species composition and size class distribution. These forest restoration treatments will affect the availability of dead wood to wildlife (e.g., prescribed fires may consume dead wood, forest operations may create snags and logs). I livetrapped small mammals in a northern Arizona ponderosa pine forest prior to restoration treatment and found that mouse species (Peromyscus species) were associated with some dead wood elements (e.g., Gambel oak [Quercus gambelii] snags, ponderosa pine snags, ponderosa pine stumps).
