The San Carlos Apache Tribe in Arizona wants to learn more about the historical characteristics of their woodlands, savannas, and grasslands so they have a target for restoration efforts. Restoring juniper woodland to savanna is a focus of the Tribe’s intensive management activities, and spatial information that would help determine where best to attempt restoration is needed.
Alterations to river flow can impact natural and cultural resources within river valleys and riparian zones.
Mountain glacier mass change affects water resources, regional ecosystems and global sea level. Understanding the physical processes that control glacier mass change requires field measurements of winter snow accumulation and summer melt. Yet field measurements only capture discrete points across the glacier surface, which can result in systematic bias.
A vital aspect of U.S. Fish and Wildlife Service fire management is to conduct fuels treatments that maintain habitat for wildlife, reduce the risk of large wildfires and maintain viewsheds.
This project builds upon wildland fire remote sensing research by addressing novel questions through the analysis of pre-fire and post-fire light detection and ranging (lidar) data and fusion with optical remote sensing.
The primary objectives of the Katahdin Woods and Waters National Monument (KAWW),Maine, mapping project were to provide the following: an accurate, tested, and up-to-date vegetation map; a vegetation classification standardized to the U.S. National Vegetation Classification and supported by vegetation plot data collected within the Monument; and a field key to vegetation for the entire monument.
In the early 2000s, Pictured Rocks National Lakeshore, Michigan, was infested by Beech Bark Disease (BBD).
Big Oaks National Wildlife Refuge (NWR) in Indiana hosts a variety of habitat types, including extensive grassland complexes and intact forests.
Although extensive work has been devoted to understanding the role of fire in maintaining ecosystem functions in upland systems, little research has focused on understanding the impact of fire on coastal wetlands or the response of birds to fire in high marsh wetlands.
Barrier islands, headlands, and coastal shorelines provide numerous valuable ecosystem goods and services, including storm protection and erosion control for the mainland, habitat for fish and wildlife, salinity regulation in estuaries, carbon sequestration in marshes, and areas for recreation and tourism. These coastal features are dynamic environments because of their position at the land-sea interface.
