SSHIAP
The Salmon and
Steelhead Habitat Inventory and Assessment Program (SSHIAP), a joint
effort of the treaty tribes and state of Washington, provides a
“living” database of local and regional habitat analyses. It
utilizes scientifically sound data to provide a platform for
tracking trends in freshwater and estuarine salmon habitat
conditions.
The Treaty Council’s habitat biologist
and geographic information specialist work
intensively with other tribes and natural resources entities to both
collect and share important data.
A key feature of SSHIAP is that it quantitatively characterizes
habitat conditions linked with stock distribution. This is designed
for local, watershed, basin and regional scale habitat analyses
focused on salmon protection and restoration efforts, and to track
trends in habitat over time.
The SSHIAP program provides a blueprint for joint tribal/state
action to define a cooperative process to implement habitat and
restoration strategies by:
*Documenting and quantifying past and
current habitat conditions;
*Providing a consistent framework for
data analysis;
*Assessing the role of habitat loss
and degradation on the condition of salmon and
steelhead stocks;
*Assisting in the development of stock- or watershed-specific
strategies for habitat
protection and restoration.

ase Study: Study shows how shorelines
have changed in 150 years
History is showing the way for salmon recovery efforts in Kitsap
County and on the Olympic Peninsula.
A tool created by the Treaty Council allows anyone, from government
agencies to private citizens, to access details about the
history of certain
shorelines and estuaries along the Strait of Juan de Fuca and
Hood Canal. The tool, in a report format, can be accessed at the
PNPTC Web site, pnptc.org.
“The information
gathered is essential in helping us manage, restore and protect
salmon habitats,” said Steve Todd, former PNPTC habitat biologist
who helped gather the data. “The history of the area plays a big
part in what we do today to help the salmon.”
Staff gathered data on 250 marshes, streams and river mouths – areas
where juvenile salmon eat, seek refuge from predators, and prepare
to migrate to the Pacific Ocean. Protecting and restoring these
habitats is important to western Washington treaty tribes because
they depend on salmon and other natural resources for cultural and
economic sustainability.
Todd and his colleagues determined how each site had changed by
comparing U. S. Coast and Geodetic Survey topographic maps from the
mid- to late-1800s to current coastal maps and aerial photos.
While some areas showed few differences, Todd was able to see major
changes in many places due to human activity, such as residential,
industrial, military and road development. The present-day look of
Ediz Hook and Port Angeles Harbor, for example, has changed
drastically by dredging, filling and other activities.
Reviews of maps and photos taken between the 1800s and today showed
how the construction of highways and housing developments were
contributing factors to the changing shoreline landscape. The
construction of Hood Canal Bridge in the 1960s, for example, made it
easier to access parts of the Olympic Peninsula. However, because of
the popularity of developing homes on sand spits, the salt marshes
associated with these spits were degraded or destroyed.
County governments, the
Hood Canal
Coordinating Council, salmon enhancement groups and private
citizens already have been using the data for planning habitat
restoration projects.
