Oregon 24k Bull Trout DistributionEntry ID: ODFW_orbulltrout
Abstract: Oregon distribution of Bull Trout, 1:24,000 scale.
These data describe areas of suitable habitat currently believed to be used by
wild, natural, and/or hatchery fish populations. The term "currently" is
defined as within the past five reproductive cycles. This information is based
on the best professional judgment of ODFW staff ... biologists and where possible,
the professional opinions of staff from other agencies.
These data are meant to supplement the ODFW 100K dataset for this species and
currently exist in point format to describe the uppermost endpoint of
distribution at the 1:24,000 scale as shown on the 1:24,000 scale USGS
quadrangles. These data will eventually be available in arc and event format
when the 24K routed hydrography becomes available for Oregon.
Areas displayed may not be used by a species of fish on an annual basis due to
natural variations in run size, water conditions, and other environmental
factors. The Natural Resources Information Management Program (ODFW) makes no
statement as to the validity of species absence in any particular area unless
the record is accompanied by a confidence rating (PUO, PSO, PMO) and the name
of the biologist who contributed the information. Origin and Production
information have recently been added to this dataset.
The purpose of the dataset is to map current and historic bull trout
distribution at the 1:24,000 scale.

Quality This is the first version of 1:24,000 (only) Bull Trout data that has been
released. It has been assigned a version 4 title in order to keep it in
sync with other 24k datasets.
All distribution data have been reviewed at least twice by the ODFW field staff
(typically district biologists). The date of entry exists in the attribute
table for each distribution record. Origin and production information have
recently been added to this dataset.
Access Constraints None
Use Constraints Please refer to the 1:100,000 scale distribution coverage (arcs/events) to
obtain a more comprehensive distribution dataset for this species. Not all
data are based on direct observations.
