Cavity-nesting birds and forest management
1980
Scott, V.E. | Whelan, J.A. | Svoboda, P.L.
The characteristics of dead trees (snags) used by cavity-nesting birds were examined in three timber types (aspen, ponderosa pine, and the subalpine zone). The number of snags with holes varied from less than 10 acres in the subalpine zone on the Fraser Experimental Forest in Colorado to 26 per 10 acres in ponderosa pine in Arizona. Size and species of snags used by cavity-nesting birds were examined and are discussed. Some managment problems andsuggestions are also discussed.
