Population and habitat viability analysis of ocelots (_Leopardus pardalis)_ in southern Texas
2006  Full Book

The ocelot (_Leopardus pardali_s) population in the United States (U.S.) was listed as endangered in 1982, with only 2 known isolated breeding populations occurring in southern Texas. Conservation concerns for ocelots included loss of dense thornshrub habitat, mortality from ocelot-vehicle collisions, and genetic erosion. In this study, we used a population and habitat viability analysis (PHVA) to evaluate 4 recovery strategies. These strategies were supplementation of additional ocelots from northern Mexico, reduced road mortality, habitat restoration, and linkage of two breeding populations for ocelot conservation management. The dissertation was divided into 4 chapters. Chapter 1 presents background information in regards to the purpose of this dissertation. Chapter 2 calculates ocelot survival rates to be incorporated into ocelot population modeling. Chapter 3 uses the VORTEX (Version 9.42) program to conduct a demographic population viability analysis (PVA) for an ocelot population located in Cameron County, Texas. Chapter 4 uses the RAMAS/GIS software program to conduct a habitat-based PVA or PHVA by linking landscape data with a demographic metapopulation model. The primary goal of this dissertation was to provide a template iii for evaluating ocelot recovery strategies in the U.S. Short-term strategies should include reducing ocelot road mortality, and the introduction of ocelots into the U.S. from northern Mexico. Long-term strategies should include the restoration of habitat around occupied ocelot habitat patches and the establishment of an ocelot dispersal corridor between ocelot breeding populations.
