What
is SaSI?
Washington's
eleven species and subspecies of native salmonid fish comprise a spectacular
commercially and culturally important biological resource. Unfortunately,
this resource is under heavy pressure from human population growth
and development. Urban and industrial land conversion, forest and
agricultural practices, water diversion, municipal water demands,
overfishing and hydropower development have contributed to the decline
of several salmonid stocks. A large recovery effort at the local,
state, and federal level is now underway to prevent further declines
and improve the condition of declining stocks.
An invaluable
tool in the process of restoring these stocks to healthy and productive
levels is the Salmonid Stock Inventory (SaSI). SaSI is a standardized,
uniform approach to identifying and monitoring the status of Washington's
salmonid fish stocks. The inventory is a compilation of data on
all wild stocks and a scientific determination of each stock's status
as: healthy, depressed, critical, unknown, or extinct.
SaSI thus is a basis for prioritizing recovery efforts and for measuring
the results of future recovery actions. SaSI is a cooperative product
of the Washington Department of Fish and Wildlife (WDFW) and the tribal
co-managers.
SaSI development
began in 1992, as an effort by 20 western Washington tribes and
the WDFW's predecessor agencies,
the Washington Department of Fisheries and the Washington Department
of Wildlife. At that time the inventory was called the Salmon and
Steelhead Stock Inventory (SASSI). The SASSI documents produced
in 1993-4, totaling some 2600 pages described and categorized the
status of 435 salmon and steelhead stocks.
In 1997 WDFW produced an additional
volume on bull trout and Dolly Varden, and with this inclusion of
salmonid fishes which were neither salmon nor steelhead, the inventory
was renamed the Salmonid Stock Inventory. The bull trout/Dolly Varden
inventory was updated in 1998. Currently a coastal cutthroat trout
stock inventory is nearing completion.
The co-managers'
original intent was to regularly update and revise SaSI documents,
and with the 1999 creation of the Salmonid Stock Conservation Biology
Unit in WDFW's Fish Program, a comprehensive updating and revision
of the SaSI documents is underway and will be completed by mid-year
2001. Thereafter the documents will be updated regularly. In addition,
new species and subspecies will be added as they become conservation
priorities. For example, we plan to produce a westslope cutthroat
trout stock inventory in 2001.
