Available in PDF, EPUB and Kindle. Book excerpt: The management of red squirrel populations relies on an extensive knowledge of the ecological, social and economic factors affecting population demography and abundance. This volume contains peer reviewed studies authored by many of the world's leading squirrel experts, and is a collection which will contriobute to the evolution of applied conservation across Europe. Early chapters describe the interaction between red and grey squirrels, and review dietary studies, scatter hoarding strategies, causes of mortality, predation impacts, genetic research, and the impact of habitat fragmentation upon squirrel dispersal. Later case studies present the challenges of managing red and grey squirrels at a local, regional and national scale.

This book was released on 1996 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: We investigated occupied squirrel middens and squirrel sightings and vocalizations as indicators of red squirrel (Tamiasciurus hudsonicus) abundance in high-elevation whitebark pine (Pinus albicaulis) zone. Data were collected 1984-1989 from line transects located on 2 study sites in the Yellowstone ecosystem. We evaluated the performance of each measure on the basis of precision and biological considerations. We concluded that, of the 3 measures, active middens were the best indicator of red squirrel abundance. We also observed that the density of active middens dropped by 48%-66% between 1987 and 1989, following a severe drought and extensive wildfires that burned one of the study sites during 1988.

Book excerpt: Reductions in whitebark pine (Pinus albicaulis) due to blister rust (Cronartium ribicola) and mountain pine beetle (Dendroctonus ponderosae) have prompted some forest managers to consider selective thinning and prescribed fire to reduce competition of whitebark pine with other conifer species. Whitebark pine is an important food source for grizzly bears (Ursus arctos horribilis) in the Greater Yellowstone Ecosystem, but most of the seeds are obtained by raiding red squirrel (Tamiasciurus hudsonicus) middens. Therefore, it is important to understand which attributes maximize red squirrel midden site selection. The objectives of this study were to estimate active midden site selection criteria and quantify the ideal conifer composition associated with red squirrel middens in the Cooke City Basin, MT. Active midden counts were collected in 810, 30-meter diameter circular plots, equally spaced along 27 transect lines in the basin. We used generalized linear mixed models to assess variables associated with middens. Midden occurrence probability was positively associated in a curvilinear relationship with conifer canopy cover and the amount of topographic shading. Midden occurrence increased as the percent of whitebark pine increased up to 44 percent. A conifer composition of 44 percent whitebark and 56 percent mixture of subalpine fir (Abies lasiocarpa) and Engelmann spruce (Picea engelmannii) was ideal for midden sites. Whitebark pine treatments to reduce fir and spruce competition should acknowledge the tradeoffs to foraging grizzly bears.
