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.
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.
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.
Maps of the ranges of tree species in North America compiled by Elbert Little and others were digitized for use in USGS vegetation and climate modeling studies. Can be downloaded as ArcView shapefiles and in PDF graphic files.
Study of the processes by which the conversion occurred of the Palouse bioregion from perennial native grass, shrub, and forest vegetation to agriculture and the interactions between human cultures and environment.
Loss of sea ice has increased ocean wave action, changing coastal habitats. For some geese this has been a positive change, increasing the amount of coastal area that supports vegetation the geese feed on.
Identification of epiphytes (plants obtaining moisture and nutrients from the air and rain and usually living on another plant) on seaweed in Tampa Bay, Florida. Abstract of symposium presentation with photos.
Interactive maps and databases showing geospatial, biologic, and ecological aspects of the upper Mississippi River. Includes water quality, fish species, and vegetation distribution as well as geographic reference information.
The Vegetation Drought Response Index is a drought monitoring and mapping tool integrating satellite observations of vegetation and climate with land cover, soil characteristics, and other environmental factors.
Comparison of water in two adjacent watersheds before and after implementing a brush management strategy in one of the watersheds helps us see what water resource characteristics are sensitive to brush management and how.
Explains how we assessed the quality of a wetland as indicated by its plant species composition and abundance for marsh and swamp sites, to summarize the effectiveness of restoration projects in Louisiana.
Homepage for the National Land Cover Data (NLCD), a land cover classification scheme, for the United States based on data derived from Landsat Thematic Mapper satellite data. Includes links to description, products, accuracy, and program partners.
Site to learn about, view, and order digital image vegetation condition (greenness) maps of the conterminous U.S. based on the Normalized Difference Vegetation Index (NDVI) with imagery from Advanced High Resolution Radiometer (AVHRR).
List of plant specimens and photo gallery of plants in the collection of the herbarium at the Patuxent Wildlife Research Center, a reference collection of plants occurring in the area lying between Baltimore, Maryland and Washington D.C.
Research results (publications, photographs, maps) on ecological processes within the Mojave Desert Ecosystem to provide land managers with scientific understanding and tools needed to conserve and restore threatened desert landscapes.
Shows how we can use remote sensing to study natural phenomena that vary seasonally but whose timing is affected by both shorter- and longer-term variations in climate or other, similar environmental conditions.
Links to science programs on upper Midwest river inventory and monitoring with links to databases on macroinvertebrates, fisheries, vegetation, water quality, bathymetry, floodplain forest, wildlife, sediment, contaminants and nutrients.
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.)
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.
