Wildlife Mortality Information –
Wildlife Organophosphate/Carbamate Poisoning (OP/CARB)

What this map layer shows:

The number of bird deaths due to organophosphate/carbamate poisoning, when each outbreak occurred, and the top five species affected, by county.

Background Information
Sample map Sample Map
Organophosphate/carbamate poisoning occurs when wildlife is exposed to organophosphate or carbamate pesticides. The poisoning results from animals eating seeds or vegetation treated with the pesticide, eating insects or other animals contaminated with the pesticide, or drinking contaminated water; poisoning can also occur through inhalation or skin exposure. Organophosphate and carbamate pesticides are relatively short lived, so wildlife exposure tends to be associated with pesticide applications. This map layer portrays the incidence of wildlife organophosphate/carbamate poisoning in the United States. It was produced by the U.S. Geological Survey's National Wildlife Health Center (NWHC), which was established to address the health and disease issues of free-ranging wildlife. The center collects information on wildlife mortality events such as those caused by organophosphate/carbamate poisoning, assesses the impact of disease on wildlife, identifies the role of various pathogens in contributing to wildlife losses, and works to develop effective disease prevention and control strategies. The wildlife organophosphate/carbamate poisoning information was extracted from NWHC's EPIZOO database, which is a long term record of more than 25 years of information on epizootics (epidemics) in wildlife. EPIZOO tracks die-offs throughout the United States and its territories, primarily in migratory birds and endangered species.

The Wildlife Mortality Information – Wildlife Organophosphate/Carbamate Poisoning database shows county-level information on wildlife organophosphate/carbamate poisoning events in the United States, including the dates of each event, the five top species involved, and the number of deaths. Also available in the National Atlas are databases describing mortality events due to avian botulism, avian cholera, and avian lead poisoning, as well as a database with county-level counts of wildlife mortality events. More detailed information on wildlife organophosphate/carbamate poisoning is available from the Human Influences chapter of Our Living Resources and from the NWHC Field Manual of Wildlife Diseases, Chapter 39: Organophosphorus and carbamate pesticides.

If you download the data for Wildlife Mortality Information – Wildlife Organophosphate/Carbamate Poisoning (OP/CARB), you may also want to download the Wildlife Mortality Information – Frequency and the 2001 County Boundaries data. The Wildlife Mortality frequency information and the County Boundaries map layers can be used together to create a map of wildlife mortality that is similar to the map in the Map Maker. The OP/CARB map layer provides additional information about specific events.
