Vegetation Data: Upper Midwest Environmental Sciences Center

Presently, the Long Term Resource Monitoring Program (LTRMP) conducts annual monitoring of vegetation using a stratified random sampling method (Yin et al. 2000) in five study reaches of the Upper Mississippi River System: Navigation Pools 4, 8, 13, and 26 on the Mississippi River; and La Grange Pool on the Illinois River. The LTRMP will continue More...

Pollinators

The global declines in many kinds of pollinator species could potentially impact the global food supply, as many plants depend upon specific pollinators to reproduce. The Web site of the NBII Pollinators Project provides access to information about the biology, ecology, conservation status, and threats to native pollinators, pollinator-dependent More...

Ecological Foundations for Fire Management in North American Forest and Shrubland Ecosystems

Fire occurs in many North American ecosystems, and most of these systems are resilient to fires that occur within a broad range of variability in frequency and intensity. In a recent USFS publication (General Technical Report PNW-GTR-779, ), USGS scientist Jon Keeley led a team of scientists from various agencies and academic institutions in More...

Monitoring Populations of Sage-Grouse: Proceedings of a Symposium at Idaho State University Hosted by University of Idaho and Idaho State University

The greater sage-grouse (Centrocercus urophasianus) and the Gunnison sage-grouse (C. minimus) are species of concern because of their population declines and shrinking geographic distributions. Of continuing interest is the question of population abundance and trends. This publication answers the questions that deal with sage-grouse population, More...

Human Influence on California Fire Regimes

Periodic wildfire maintains the integrity and species composition of many ecosystems, including the Mediterranean-climate shrublands of California. However, human activities alter natural fire regimes, which can lead to cascading ecological effects. Increased human ignitions at the wildland-urban interface (WUI) have recently gained attention, but More...

Vegetation responses to natural regulation of elk in Rocky Mountain National Park

A quasi-experimental situation exists in Rocky Mountain National Park, where elk (Cervus elaphus) populations have increased 3-fold since 1968 following their release from artificial controls within the park. Increases in elk habitat use and decreases in deer habitat use were observed. Significant increases in cover of mosses and lichens occurred More...

It's in the Air: The Ecological Effects of Nitrogen Deposition in Rocky Mountain National Park

Encroaching development, overuse, and air- and waterborne contaminants from outside park boundaries are causing noticeable changes to water quality and ecosystem health and functioning. The Front Range metropolitan area from Fort Collins south to Colorado Springs includes 75 percent of Colorado's population and its most productive agricultural 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...
