Survival and movements of translocated raccoons in northcentral Illinois

Article Abstract:

The survival rates and dispersal of translocated raccoons following release were investigated. In addition, the causes of mortality of among raccoons translocated from an urban to a rural area and vice versa were also examined by radiotracking 31 raccoons in northcentral Illinois. It was found that resident raccoons were likely to remain in the vicinity of the release site while their translocated counterparts tended to leave the release site almost immediately and disperse into the surrounding area. Dispersing raccoons had high daily movement rates for the first two weeks of release and appeared to establish new home ranges.

Survival and movements of translocated raccoons in northcentral Illinois

Article Abstract:

Research undertaken in southern Kane County and northern Kendall County, IL, into postrelease survival rates and dispersal of translocated raccoons indicates that the survival of translocated raccoons is determined by a number of factors, including population density at the release site and the quality of habitat at the release site. Survival rates of translocated raccoons can be as high as those of resident animals, and this therefore indicates that translocation can be a humane way of dealing with nuisance wildlife. However, problems can arise when translocated raccoons begin competing for resources with resident raccoons.

Effects of livestock grazing on small mammals at a desert cienaga

Article Abstract:

Livestock in dry regions tend to graze close to riparian areas and other habitats where water, shade and tasty vegetation is commonly available. These areas are also important to wildlife and the effects of livestock grazing is of concern to wildlife managers. Details of a 10-year study designed to show the effect of livestock grazing on small mammals and vegetation at a desert wetland in southwestern Mexico are presented. Results show that there were consistently more small mammals on the plots from which livestock was excluded, reflected by comparable differences in vegetation.
