Book excerpt: The concern over the lack of information on red foxes (Vulpes vulpes), gray foxes (Urocyon cinereoargenteus), and raccoons (Procyon lotor) has prompted the Kentucky Department of Fish and Wildlife Resources to investigate new methods to permit reliable monitoring of these populations. The potential for the use of computer simulation modeling as a means of realizing the cause and effect in population fluctuations was the catalyst for the initiation of this investigation. Basic requirements for population modeling are knowledge of age class distribution and reproductive rates. The objectives of this investigation were to estimate both the age structure of Kentucky's raccoons, red foxes and gray foxes and their respective reproductive rates for use in the development of a simulation model (Cobb 1985).
