A major focus of USGS-LSC is the design and evaluation of state-of the-art upstream and downstream fish passage structures for hydropower facilities of different sizes and locations and for different fish species, including endangered sturgeons and Atlantic salmon. Performance, physiology, behavior and energetics of each fish species are tested in-house for each design.
Barrier islands provide numerous invaluable 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, recreation, and tourism. These islands are dynamic environments due to their position at the land-sea interface. Storms, wave energy, tides, currents, and...
Mosquito control on Department of the Interior (DOI) managed lands is a resource management challenge. The pesticides used to control mosquitoes may also affect nontarget organisms whose conservation is one of the primary responsibilities of resource managers.
The Challenge: Bird banding is one of the most indispensable techniques for studying the movement, survival and behavior of birds. The North American Bird Banding Program was established in 1920 and has evolved into the complex operation that supports the activities of approximately 2,092 Master banders and more than 9,423 subpermittees.
The Status and Trends Program provides timely, quality science about arid and semi-arid lands to meet the needs of resource management bureaus within Interior and other science and resource management organizations.
In the 21st century, drivers such as sea level rise, extreme weather events, changes in the flow rate of rivers, and human development of coastal habitats will affect coastal landscapes and ecosystems across the region, including estuaries.
Information about the status and trends of natural resources is required at a variety of spatial and temporal scales to detect changes that may signal degradation or improvement of natural systems, such as habitat, or to identify new or emerging conditions that signal the need for management action or further investigative research.
The status and trends of organisms, habitats and ecosystems is often controlled by environmental and anthropogenic stressors that have the potential to impact the health and productivity of lands and waters of management concern.
Wetlands provide goods and services that have been valued at up to $78,500 per acre per year (R. Costanza and others, Global Environmental Change 2014). In addition to providing fish and wildlife habitat, coastal ecosystems protect coastlines from storms, store carbon in sediments, improve water quality, and maintain productive coastal fisheries. In the 21st century, drivers such as sea level...
