Wildlife Mortality Information – Frequency Data
What this map layer shows: The number of wildlife mortality events due to botulism, cholera, lead poisoning, or organophosphate/carbamate poisoning, by county.
Background Information
Sample Map The U.S. Geological Survey's National Wildlife Health Center (NWHC) was established to address the health and disease issues of free-ranging wildlife. The NWHC collects information on wildlife epidemics in migratory birds and endangered species, assesses the impact of diseases on wildlife, identifies the role of various pathogens in contributing to wildlife losses, and works to develop effective disease prevention and control strategies. In addition, the staff of the NWHC works to improve our understanding of the ecological relationships between free-ranging wildlife and domestic animals and investigates public health concerns involving diseases that can be transferred from animals to humans under natural conditions. Wildlife die-offs throughout the United States and its territories, primarily in migratory birds and endangered species, are tracked through NWHC's EPIZOO database, which is a long-term record of more than 25 years of information on epizootics (epidemics) in wildlife. This map layer was produced by the U.S. Geological Survey's NWHC from information contained in the EPIZOO database. The Wildlife Mortality Information – Frequency Data database includes information on the number of wildlife mortality events, per county in the United States, caused by four different agents: avian botulism, avian cholera, avian lead poisoning, and wildlife organophosphate/carbamate poisoning. Four additional databases provide detailed information on each wildlife mortality event: the Wildlife Mortality Information – Avian Botulism database, the Wildlife Mortality Information – Avian Cholera database, the Wildlife Mortality Information – Avian Lead Poisoning database, and the Wildlife Mortality Information – Wildlife Organophosphate/Carbamate Poisoning (OP/CARB) database. Further detail on wildlife mortality and disease epidemics is available from the NWHC Disease Information page.
