Report on the captive breeding program at Patuxent Wildlife Research Center to help save endangered whooping cranes. Site links to natural history information on whooping cranes, why they are endangered, cool facts on cranes, and a photo gallery.
Gateway to useful USGS websites for recreation in nature watching and exploring, boating, camping, climbing, fishing, hiking, biking, and hunting, with links to maps, real-time streamflow, geology, photos, and plant and animal information.
The USGS-NPS Vegetation Mapping Program is a cooperative effort with the National Park Service (NPS) to classify, describe, and map vegetation communities in over 270 U.S. national park units with links to overview, standards, products, and applications.
Outlines tactical problems that make it difficult for beach managers to use scientific information to make beach closure and advisory decisions. Explains methodologies we are using to address those problems and better prepare local decision makers.
This endangered species prefers native trees in large, continuous areas of riparian habitat. Armed with this information, resource managers may identify and preserve areas favorable to this population.
We use moderate resolution satellite data to assess live fuel condition for estimating fire danger. Using 23 years of vegetation condition measurements, we are able to determine the relative greenness of wildland vegetation susceptible to burning.
Describes investigative techniques focused on genetic characteristics of individuals and populations, and explains how this information helps improve existing natural populations and potentially impede invasive populations.
Over 30 years of substantial warming, the timing of life cycle events in maize here has changed, threatening the crop yield by exposing the plant at sensitive phases in its life cycle to increased heat and drought, and lowering the weight of its grains.
Summarizes studies that took place in this ecoregion. Some studies occurred in areas without post-fire management, and others in moderately or intensively managed areas. Some of the research also occurred immediately after a wildfire, and other work occur
Report of a pilot study to classify vegetation communities in parts of the Smoky Mountains National Park by sampling vegetation in selected areas with information on field methods and data analysis and lists of communities identified.
Identification manual with colored photos of species of puddle ducks, diving ducks, geese, mergansers, swans, cranes, herons, egrets, pelicans and cormorants. Also includes information on ordering print copy and downloading as *.zip file.
Links to research at the field stations of the Western Ecological Research Center with direct links to web pages for wildlife videos, satellite telemetry, fire ecology, invasive species, herpetology field guide, and coastal ecosystems.
Information on the NWRC Wetlands Ecology Branch, which conducts research related to sustainable management and restoration of the nation's coastal saltwater wetlands, freshwater wetlands, submerged aquatic ecosystems, and coastal prairie.
Shooting them doesn't work, they just breed more. And they trample on the native plants. These animals were brought to the islands during the last 150 years, and we're trying to develop ways of managing their impact on the native life.
How will the increasing use of wind turbines affect populations of wild birds and bats? This shows which birds and bats we study, and the aspects of their ecology that may be affected by wind energy development.
