Invasive Species Data and Maps

Data and Maps

The CRISIS Mapping tool is an interactive map display and data viewer for weed observations in the regions of California and the Southwest.

From the Southern Appalachian Man and the Biosphere (SAMAB) Program, this page provides links to printable maps, success stories, graphs, draft standards, and photos related to invasive plants in the Appalachians, as part of a partnership with the NBII's Southern Appalachian Information Node (SAIN). Visit their interactive mapping application to view individual species distributions today!

Discover Life Global Mapper
- Global distribution maps of species, currently under development. Links to museum records from the Missouri Botanical Garden and others.
Interactive Maps of Oahu
- Maps of Oahu integrate a variety of GIS layers including incipient weeds, aquatic species distribution (both native and non-native), and remaining native natural communities in Hawaii. The maps make extensive use of JavaScript and require a browser version 4.0 or higher. Microsoft Explorer for Macintosh is not supported.
Sample data synthesis
- Database(s) containing plot data, polygon data, and point data on the occurrence of non-native species can be merged to improve each individual dataset and create a better knowledge base of non-native species.
Susceptibility to Noxious Weed Invasion in the Pacific Northwest
- Susceptibility to cheatgrass, Bromus tectorum, has been plotted for the Columbia River Basin in this map served by the NBII's Pacific Northwest Information Node (PNWIN).
Yellowstone National Park Invasive Species
- Click on the square next to "Weed types identified in 1998 - NPS" and refresh the map. This is part of the Greater Yellowstone Area GIS Database, created by many partners including Montana State University, a principle player in the NBII's Northern Rockies Information Node (NRIN).
