Annual spawner data from Endangered and Threatened PNW salmonids

Description

The data set has yearly spawner counts for endangered and threatened ESU (Evolutionary Significant Units) and DPS (Distinct Population Segments) in the Washington and Oregon. Data were downloaded from Coordinated Assessments API. Coordinated Assessments data eXchange (CAX) is developed by the Coordinated Assessments Partnership (CAP).

Usage

data(esa_salmon)

Format

Objects of class "data.frame". Columns are species, esu_dps, majorpopgroup, commonpopname, run, spawningyear, spawner, log.spawner

Details

There are two datasets included: esa.salmon and columbia.river. The Columbia River data set is a subset of the esa.salmon dataset that has all the ESUs and DPSs. The dataset has the following columns

  • species: Chinook, Coho, Steelhead, Chum, Sockeye

  • esu_dps: name of the ESU

  • majorpopgroup: biological major group

  • commonpopname: common population name, generally a stream or river

  • run: run-timing

  • spawningyear: the year that the spawners were counted on the spawning grounds

  • spawner: total (natural-born and hatchery-born) spawners on the spawning ground. Generally some type of redd-count expansion or some other stream count of spawners. Redd = a gravel nest.

  • log.spawners: log of value

Source

CAP StreamNet Coordinated Assessments Partnership (CAP) standardized high-level indicators (HLIs) for Natural Origin Spawner Abundance (NOSA).
