The Comprehensive Invasive Phragmites Management Planning project was completed to create an adaptive management plan for invasive phragmites control in the Saginaw Bay of Lake Huron, Michigan. Phragmites is a tall grass that chokes shorelines, limiting access for recreation activities, displacing fish and native vegetation, and creating a fire hazard.

The FWS Division of Migratory Bird Management is integrating remote sensing technology to enhance the safety, data quality, and cost-efficiency of migratory bird surveys that inform management decisions. Recent investments include 1) acquisition of data storage and high-performance computing resources and integration of these resources into the FWS’s information technology
In the Great Lakes Basin, wetlands are considered to be the most vulnerable landscape feature subject to human actions and climate change. The wetlands are part of the water infrastructure and provide flood storage, storm surge protection, carbon storage, clean water, and unique fish and wildlife habitats. The public and wetland managers are asking for more frequent updates of wetland and adjacent habitat change. Monitoring wetlands seasonally is
Current and accurate wetland maps are required for a variety of uses. Individual land owners, non-profit organizations such as Ducks Unlimited, local governments, and state and Federal governments use wetland maps regularly to help plan for land management, development, and restoration. Wetland permitting, environmental impact statements, and transportation planning processes are more efficient and cost-effective if there are current and accurate wetla
FWS scientists used multitemporal Landsat imagery in Google Earth Engine to construct seasonal averages of temperature and turbidity along the entire length of the Lower Mississippi River. In battue open waters (near shore within levees), results indicate that oxbows and other off channel open waters tend to be warmer and less turbid than main channel conditions; water bodies that are more well-connected with the river tend to be more turbid and cooler durin
Documenting bird and bat migration is challenging because migration activity is sporadic, and nocturnal migrants (most aerial vertebrate migrants) are difficult to observe.
Seasonal Drought in North America’s Sagebrush Biome Structures Dynamic Mesic Resources for Sage‐grouse
The North American semiarid sagebrush biome exhibits considerable climatic complexity driving dynamic spatiotemporal shifts in primary productivity. Greater and Gunnison sage-grouse are adapted to patterns of resource intermittence and rely on stable adult survival supplemented by occasional recruitment pulses when climatic conditions are favorable.
A key vegetation parameter important to maintaining Golden-cheeked Warbler (hereafter warbler) breeding habitat is the amount of broadleaf versus Ashe juniper tree cover on a site. Mixed composition woodlands with mature Ashe juniper trees provide enhanced foraging opportunities through high arthropod diversity and supply juniper bark used for nesting.
FWS National Wildlife Refuges (NWR) that contain impoundments used to provide shorebird and waterbird habitat are required to report on the available habitat area by depth class as the water levels change in the impoundments during the migration seasons.
