Document on the National Vegetation Classification Standard with information on applications, background, development, characteristics, nomenclature standards, relationship to other classifications, and how to do vegetation mapping.
Description of the Status and Trends program, which monitors the abundance, distribution, productivity, and health of the Nation's living resources, detecting and evaluating changes in these variables over time.
Report on the status of the biota and ecological factors of the inland lakes of the Great Lakes Cluster Parks: Indiana Dunes, Sleeping Bear Dunes,and Pictured Rocks National Lakeshores and Isle Royale and Voyageurs National Parks. (PDF file, 321 p.)
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.
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.
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.
