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.
