New Zealand Mudsnail Sightings Distribution
This map layer is a compilation of confirmed
New Zealand mudsnail sighting reports in the United States and Canada from 1987 through 2011 and is updated daily.
It provides geographical and historical information to show distribution
over space and time. The reports came from a variety of Federal, State, and
municipal agencies, universities, public utilities, engineering and
private consultant firms. These data are intended for geographic display and analysis at the
national level, and for large regional areas. Sightings were reported with varying levels of accuracy.
The data should be displayed and analyzed at scales appropriate for 1:2,000,000-scale data.
No responsibility is assumed by the U.S. Geological Survey in the use of these data. Acknowledgment of the U.S. Geological Survey would be appreciated in products derived
