Fish Passage

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.

Louisiana Barrier Island Habitat Mapping and Change Assessment

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...

Habitat

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.

Wetlands

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...
