The Everglades National Park (EVER) and Big Cypress National Preserve (BICY) vegetation mapping project is part of the Comprehensive Everglades Restoration Plan, a cooperative effort between the South Florida Water Management District, the U.S. Army Corps of Engineers (USACE), and the NPS Vegetation Mapping Inventory Program (VMI).
The National Park Service (NPS) has a substantial investment in and a long history of using aerial and spaceborne remote sensing and global positioning system (GPS) technologies. The NPS Inventory & Monitoring Program conducts baseline inventories for more than 270 parks across the Nation. Remote sensing data are a critical source of information regarding geology, soils, vegetation, and infrastructure. Aerial photography and satellite imagery have been utilized to compile vegetation maps; a monumental task given the agency has responsibility for over 30 million acres. These data are particularly critical for NPS activities in Alaska, because of its remote and vast expanses of public land and the fact that the Arctic is warming rapidly in response to climate change. The NPS takes advantage of the free Landsat archive to quantify decadal changes in glacier ice cover and document land cover change in national park units. The NPS has been the Department of Interior’s (DOI) sponsoring agency to map all large wildland and prescribed fires as part of the DOI Monitoring Trends in Burn Severity project, using the Landsat archive. GPS supports field data collection, navigation, and search and rescue operations conducted by the agency.
Physical scientists at Kenai Fjords National Park in Alaska have been using remote sensing methods to monitor an unnamed glacial ice-dammed lake (IDL) and the subsequent glacial lake outburst floods (GLOFs) that regularly occur at Bear Glacier to understand the timing, frequency, and drivers that lead to GLOFs.
Dramatic warming in the Arctic is accelerating the melting of snow and ice. The NPS Arctic Inventory and Monitoring Network (ARCN) is using Landsat satellite images to monitor the area of lakes and ponds in the five NPS units in northern Alaska. Water surface area trends were computed using both the new U.S.
The NPS Arctic Inventory and Monitoring Network (ARCN) is using high-resolution satellite images and historical color infrared aerial photographs to monitor the abundance of small landslides resulting from thaw of permafrost. Active-layer detachments (ALD) and retrogressive thaw slumps (RTS) are small landslides that occur as a result of thaw in permafrost regions.
Caribou (Rangifer tarandus) are an iconic species of the north and an integral component of the natural ecosystem and socioeconomic wellbeing of local communities. Alaska is home to 32 different caribou herds which are identified by females returning to specific calving areas each spring to give birth.
Many prehistoric sites located throughout Alaska are surface scatters of lithic (rock) debris, either remaining exposed since occupation or re-exposed due to erosion. Due to their open nature, these sites are often interpreted to lack much of their original context and integrity.
Remotely sensed data and derived information contribute significantly to mission-critical work across the Department of the Interior (DOI). This report from the DOI Remote Sensing Working Group (DOIRSWG) highlights a sample of DOI remote sensing applications and illustrates the many types of technology, platforms, and specialized sensors employed.* DOI personnel use remote sensing technology to evaluate and monitor changing land-surface and natural resource conditions over the vast areas for which DOI has responsibility.
Alaska’s boreal forest burns every summer somewhere. To predict which areas are most susceptible to wildfire, managers assess fuel dryness and burnability using weather data collected at Remote Automated Weather Stations (RAWS). Managers must start gathering these data within just a few days after the snow has melted away from a weather station in the spring. But snow melts unevenly.
The Everglades National Park (EVER) and Big Cypress National Preserve (BICY) vegetation mapping project is part of the Comprehensive Everglades Restoration Plan (CERP). The CERP is a cooperative effort between the South Florida Water Management District (SFWMD), the U.S. Army Corps of Engineers (USACE), and the National Park Service (NPS) Vegetation Mapping Inventory Program (VMI).
Bering Land Bridge National Preserve and Cape Krusenstern National Monument encompass approximately 1,600 km of predominantly soft-sediment Arctic coastlines rich in biological resources.
