Resource Abstract:
- description: Evaluating the status of threatened and endangered salmonid populations requires information on the current status
of the threats (e.g., habitat, hatcheries, hydropower, and invasives) and the risk of extinction (e.g., status and trend in
the Viable Salmonid Population criteria). For salmonids in the Pacific Northwest, threats generally result in changes to physical
and biological characteristics of freshwater habitat. These changes are often described by terms like "limiting factors"
or "habitat impairment." For example, the condition of freshwater habitat directly impacts salmonid abundance and
population spatial structure by affecting carrying capacity and the variability and accessibility of rearing and spawning
areas. Thus, one way to assess or quantify threats to ESUs and populations is to evaluate whether the ecological conditions
on which fish depend is improving, becoming more degraded, or remains unchanged. In the attached spreadsheets, we have attempted
to consistently record limiting factors and threats across all populations and ESUs to enable comparison to other datasets
(e.g., restoration projects) in a consistent way. Limiting factors and threats (LF/T) identified in salmon recovery plans
were translated in a common language using an ecological concerns data dictionary (see "Ecological Concerns" tab
in the attached spreadsheets) (a data dictionaries defines the wording, meaning and scope of categories). The ecological concerns
data dictionary defines how different elements are related, such as the relationships between threats, ecological concerns
and life history stages. The data dictionary includes categories for ecological dynamics and population level effects such
as "reduced genetic fitness" and "behavioral changes." The data dictionary categories are meant to encompass
the ecological conditions that directly impact salmonids and can be addressed directly or indirectly by management (habitat
restoration, hatchery reform, etc.) actions. Using the ecological concerns data dictionary enables us to more fully capture
the range of effects of hydro, hatchery, and invasive threats as well as habitat threat categories. The organization and format
of the data dictionary was also chosen so the information we record can be easily related to datasets we already posses (e.g.,
restoration data). Data Dictionary.; abstract: Evaluating the status of threatened and endangered salmonid populations requires
