Development and Refinement of Methods for Early Detection of European Green Crab
European green crabs are one of the most widespread marine invasive species on the planet. Where they are abundant, green crabs compete with other crabs and disturb sediment which can lead to loss of eelgrass and associated habitat essential for commercial, cultural, and ecologically important fish and invertebrate species. Green crab also are a major predator of clams, mussels, and oysters.
Southwestern Willow Flycatcher Habitat Viewer
For planning and management purposes, agencies require a web application that can locate, map, and monitor Southwestern Willow Flycatcher (flycatcher) breeding habitat across its range. The Habitat Viewer can identify potential flycatcher habitat and monitor changes caused by stressors, such as beetles, fire or drought.
Early Detection Monitoring May Not Be Sufficient for Invasive Mussels in the Columbia River Basin
The ecological and economic costs of an invasive quagga or zebra mussel infestation in the Pacific Northwest of the U.S. would be significant. The development of invasive mussel monitoring programs in the Pacific Northwest provides a unique opportunity to evaluate a regional invasive species detection effort early in its development. Although efforts are underway to monitor for the presence of...
Columbia River Basin Sturgeon Habitat Modeling
A study was conducted to identify habitat characteristics associated with age 0 White Sturgeon ( Acipenser transmontanus Richardson, 1863) recruitment in three reaches of the Columbia River Basin: Skamania reach (consistent recruitment), John Day reach (intermittent/inconsistent recruitment), and Kootenai reach (no recruitment).
Scientific Support of Salmon and Steelhead Reintroductions in Impounded River Basins of the Pacific Northwest
Salmon and steelhead populations in the Pacific Northwest were severely affected by hydropower development that occurred during the first half of the 20th century. Impassable dams were constructed on many rivers throughout the region which prevented returning adult salmonids from accessing important habitats where spawning and rearing historically occurred. In the past two decades resource...
Steelhead Life History Study in White Creek on the Yakama Nation Reservation
Fishery biologists from the U.S. Geological Survey have teamed with fishery biologists from the Yakama Nation to conduct a life history study of the juvenile steelhead using small electronic tags.
Rock Creek Fish Population and Life History Assessment (Washington)
The research conducted by the U.S. Geological Survey, in coordination with the Yakama Nation, is designed to determine stream habitat conditions, fish abundance, and fish life history characteristics such as movement, growth, and distribution.
Steelhead and Spring Chinook Adult Spawning Migration Study in the Klickitat River (Washington)
Fishery biologists from the U.S. Geological Survey are cooperating with Yakama Nation fishery biologists and technicians to conduct a migration behavior study of returning adult steelhead and spring Chinook using radio telemetry.
