• Ecological Concerns Data Dictionary - Ecological Concerns data dictionary

    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).
