Description

Abstract: Oregon Fish Habitat Distribution. These data describe areas of suitable habitat believed to be used currently or historically by wild, natural, and/or hatchery 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 March 2015. The Standard document can be found at: https://www.oregon.gov/geo/standards/Oregon%20Fish%20Habitat%20Distribution%20Data%20Standard,%20v3.0.pdf Historical habitat distribution data are now 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 now mapped at a 1:24,000 scale statewide and are based on the Pacific Northwest Framework 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 2016. Data were migrated to the NHD in 2014 and are compatible with the USGS Hydrography Event Management Tools. Note: Please contact the ODFW GIS Coordinator if you are interested in NHD formatted fish habitat distribution data.

Purpose: To provide an inventory of fish habitat distribution for documentation, mapping and analysis.

Data Quality Information

Lineage-Source: These data were primarily created through a process where 1:100,000 scale fish habitat distribution data (current as of 2001) were plotted on 1:24,000 scale USGS quadrangle maps and then provided to ODFW and other natural resources agency field staff. Based on survey data, supporting documentation, and the best professional judgment of the field biologists, different types (spawning, rearing, migration, etc.) of species specific habitat distribution (see the fhdUseTy field) were marked on the maps with colored pens. Additional attributes such as source contributors, agencies and the basis of the data were also collected. These hardcopy data were then digitized by ODFW GIS staff and stored as event tables based on the PNW River Reach files at 1:100,000 scale. Habitat locations identified outside of the 1:100,000 scale stream network were captured as upstream points associated with 1:24,000 scale streams. Beginning in 2007 and ending in 2008, the data were migrated to events associated with the Pacific Northwest Framework Hydrography 1:24,000 scale stream network. All habitat distribution records are now in a single, consistent linear event format. Revisions: The first 1:100,000 scale version of the data was completed in 1996. Significant revisions at that scale were also made in 1999. The 1:24K Mapping Project occurred between 2001 - 2003 and data were published in 2004. Data were migrated to events mapped on the 1:24,000 PNW Framework hydrography in 2007 and 2008. Significant revisions since 2004 include additions of anadromous habitat in the upper Deschutes and upper North Santiam basins, steelhead and coho habitat in the coastal basins. Numerous, less significant revisions have occurred throughout the state, in particular where the location and passage status of blocking barriers was recently verified. Historical habitat distribution data were added to the datasets in 2011 and 2012. Reviews_Applied_to_Data: All distribution data have been reviewed by ODFW or other natural resource agency staff (typically district biologists). The date of last review exists in the attribute table for each distribution record. Related_Spatial_and_Tabular_Data_Sets: Oregon Fish Passage Barrier Data Standard Dataset.
