Data and Models
An essential part of the Technical Recovery Team (TRT) planning and
analyses process was the creation of various tools to assist in
salmon recovery research topics. In conjunction with this, the teams also compiled and synthesized datasets on abundance, productivity, and genetics to aid in various population and recovery-related analyses. This was done with the help of TRT-derived tools and models. Tools and data provided here are from various TRTs. For more information, please contact the individual listed with the dataset.

Maps and Spatial Data
The TRTs generated a variety of spatial data sets and maps as part
of their analyses. We have made some of these datasets available
here. The two primary spatial data sets created by the TRTs are population
boundaries and reach-level habitat information. These data are
intended to be used by federal, tribal, state, and
local recovery planners in evaluating the location, extent, and ESA
status of salmon and steelhead populations. Data would be helpful
in prioritizing specific recovery actions such as barrier removal, and
the influence of limiting factors.

Understanding the historical structure of populations in addition to their abundance and life history characteristics provides a framework for comparing the historic and present status of populations, the changes that have affected them, and the restoration of processes that may be necessary to recover them.
These boundaries are essential products of the TRTs, as they are the
primary spatial representation of the genetic, demographic, ecological,
and biological variability within the ESU. Populations (and designated
population boundaries) were used in the viable
salmonid population (VSP) analyses.
Links and data download are provided for the following ESU
boundaries through this website. Please note that ESU boundaries
are provided by the Northwest Regional Office, and were created prior
to the work of the TRTs. We provide them here because they can be used
in conjunction with the TRT-derived population-scale data.

Salmon and
Steelhead Habitat Atlas (Willamette-Lower
Columbia)
This atlas was developed as reference material for salmon and steelhead recovery planning in the Oregon Lower Columbia and Willamette basins. We provide information summarized at the scale of populations as defined by the WLC-TRT. Maps and summary information are presented in a uniform manner for all watersheds. The atlas does not provide an explanation of how the compiled data and summary statistics should be used in recovery planning.
In selecting the material to present in this atlas, we have focused
on
information that was both of clear relevance to salmon recovery and was
relatively readily available in consistent format at this large spatial
scale. The limitations of available data prevented inclusion of many
types of information that would be very useful for recovery planning
(e.g. detailed water quality maps or exotic species distribution maps).
Even given these limitations, an initial picture of salmon habitat in
the Lower Columbia and Willamette basins emerges. Click here to
