Oregon Fish Habitat Distribution - Current and Historical Chum Salmon
- Description:
Oregon Fish Habitat Distribution.These data describe areas of suitable habitat believed to be used currently or historically by chum salmon fish populations. The term "currently" is defined as within the past five reproductive cycles. Historical habitat includes suitable habitat that fish no longer access and will not access in the foreseeable future without human intervention. This information is based on sampling, the best professional opinion of Oregon Dept. of Fish and Wildlife or other natural resources agency staff biologists or modeling (see the fhdBasis field). Due to natural variations in run size, water conditions, or other environmental factors, some habitats identified may not be used annually. These data now comply with the Oregon Fish Habitat Distribution Data Standard that was adopted by the Oregon Geographic Information Council in June 2015. The Standard document can be found at: http://www.oregon.gov/DAS/CIO/GEO/fit/bioscience/docs/OregonFishHabitatDistributionDataStandardv3.pdf. Historical habitat distribution data are within the scope of the standard and are identified via the habitat use (fhdUseType) attribute. Historical habitats are only identified outside of currently accessible habitat and are not comprehensive. Key features of the Oregon Fish Habitat Distribution Data include: species, run, life history, habitat use, origin, production, the basis for each record, originator name, originator entity and reference. Habitat distribution data are mapped at a 1:24,000 scale statewide and are based on the National Hydrography dataset. The data are made available as GIS files in both shapefile and ESRI geodatabase format. The data were developed over an extensive time period ranging from 1996 to 2019. The data are now managed on the National Hydrography Dataset and have been synchronized to April 2019 NHD geometry.
