Nonnative Plant Inventory

Name: Nonnative Plant Inventory
Published: 2007

This is a geospatial dataset showing noxious and nonnative weed locations mapped in 2007 at Craters of the Moon National Monument and Preserve. The intended use of all data in the park's GIS library is to support diverse park activities including planning, management, maintenance, research, and interpretation. These are vector point, line, and polygon files showing the locations of noxious weeds throughout Craters of the Moon Monument and Preserve. This zipped file contains weed locations smaller than 5 meters in diameter (weed points), with a linear distribution (weed lines), and those covering areas larger than 5 meters in diameter (weed areas). This is not a comprehensive survey of the entire park. The coordinates for this dataset were collected using a Trimble Geoexplorer 3. Additional Points originally collected before 2007 were taken from Craters of the Moon's Weeds 2006 data set. Additional coordinates for this dataset were collected by a Student Conservation Association weed crew in 2007 using a Trimble GeoXT GPS unit, as well as by the Northern Rocky Mountains Exotic Plant Management Team (EPMT) using a Trimble GeoXT GPS unit. Most of the weed points were treated mechanically by hand. Knapweed points were sprayed with herbicide and some of the more remote points in the wilderness area were mapped but were not treated.
