New Zealand Mudsnails in Yellowstone and Grand Teton National Parks
This mapping project was initiated and supported by the National Park Service, Yellowstone
National Park through a contract to B. L. Kerans (Montana State University-Bozeman), M. F. Dybdahl
(Washington State University) and R. Hall (University of Wyoming).
The mapping system was prepared by D. L. Gustafson (Montana State University).
The goal of the project was to document the distribution and abundance of
Potamopyrgus antipodarum, the New Zealand mudsnail in the Greater Yellowstone ecosystem.
The web document contains current information on New Zealand mudsnail, including
location (e.g., latitude, longitude and other information), date of collection, estimates of mud
snail abundance and contact addresses if additional information is needed.
Information is continually being updated.
The mapping system is fully dynamic to provide greater versatility and ease of maintenance.
In all of the maps, red dots indicate positive collection sites.
You can get additional information by clicking on the dots.
