Raccoon Populations: Does Human Disturbance Increase Mortality?

Human disturbance is thought to be the major cause of mortality in raccoon (Procyon lotor) populations in North America. To test that hypothesis, characteristics of raccoon populations associated with low human disturbance (no trapping, low vehicular traffic, etc.) and high human disturbance (trappi...

520 |a Human disturbance is thought to be the major cause of mortality in raccoon (Procyon lotor) populations in North America. To test that hypothesis, characteristics of raccoon populations associated with low human disturbance (no trapping, low vehicular traffic, etc.) and high human disturbance (trapping, moderate vehicular traffic, etc.) were compared in the Manhattan, Kansas area in fall 1986. Estimated annual mortality in the raccoon population exposed to little human disturbance was 26.5%, significantly lower than the 52.5% in the population inhabiting an area of high human disturbance. Counts of placental scars reflected greater reproductive activity in the raccoon population in the highly disturbed area. The higher reproductive activity of raccoons inhabiting the area of high human disturbance may offset the higher mortality experienced by that population.
