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 February 2011. The Standard document can be
found at:

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 2012.
-
- Purpose: To provide an inventory of fish habitat distribution for documentation, mapping and analysis.
-
- Time Period of Content: 1996 - 2014
- Geographic Extent: Oregon
- Status: Final
- Use Constraints: Care was taken in the creation of these themes, but they are provided "as is". The Oregon Dept. of Fish and Wildlife cannot accept any responsibility for errors, omissions, or positional accuracy in the digital data or underlying records.
- Format: GIS shapefile and ArcGIS version 10.1 file geodatabase
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.
