A Compendium of Viable Salmonid Population Abundance and Productivity Field and Analysis Methods for Natural Origin Steelhead Populations in the Middle Columbia River DPS of Northeast Oregon from 1959 to 2015
"Goals of this report are to provide a thorough explanation of methods and changes to the methods included in the natural origin spawner abundance (NOSA) and recruits per spawner (RperS) datasets Viable Salmonid Population (VSP) indicators and metrics. The VSP indicators are used to assess the current status of the populations, in terms of extinction risk. These abundance and productivity VSP indicators are in the DES, along with brief methods and changes to methods for those indicators and metrics. Full DES records can be quite large tables and are not presented in this compendium ... One final goal of this report is to provide a citable reference for co-managers and interested parties when referencing ODFW abundance and productivity data in their own reports and analyses."--From Compendium Format and Goals section (page 2).
