Past, Recent, and 21st Century Vegetation Change in the Arid Southwest

The purpose of this research project is to document vegetation change in the arid lands of the southwestern United States. The project compiles data on past and present plant distributions. These plant distributions are combined with data on past, present, and future climates to predict future plant distributions. The project requires four major More...

Satellite Image Mosaics of Recent Fire Years From Western Montana and Central Idaho

This site reflects satellite image mosaics of recent fire years from western Montana and central Idaho. Mosaic PDF versions of maps from 2000, 2003, and 2007 are available, and are intended to assist by providing the location of notable burns for the more significant fire years in western Montana and central Idaho. The aim is also to provide a More...

Southwest Exotic Plant Information Clearinghouse

The Internet Map Server (IMS) visually displays the non-native, invasive plants (weed) occurrences in the current (2003) SWEMP database. An IMS allows you to interactively draw, query, and print maps. The SWEMP IMS was developed from ESRI's ArcIMS presentation product.The Southwest Exotic Plant Information Clearinghouse is a cooperative effort More...

Headwater Stream Barriers in Western Oregon

This dataset is an ArcInfo point coverage depicting obstacles to anadromous fish migration in western Oregon. Data were compiled by fourth-field hydrologic unit code (HUC) from the Oregon Department of Fish and Wildlife StreamNet Database and from reports by fisheries biologists in various management agencies. Both natural and constructed (e.g., More...
