A. Data set histories vary depending on the metric and spatial scale. See the data matrix on the Data Download page for more detail.
A. Yes. All metadata documents are available on the metadata page. In addition, the Summary Table Builder and each ESU, strata, and population page contains links to metric-specific metadata. Metadata documents are also contained within each download file.
A. To access that information use either the Summary Table Builder or the Data Download tool.
Method 1: Using the Summary Table Builder you can select the population (river basin) of interest and generate a data table for a given metric and time period. To find out how many adult salmon spawners there are in a particular stream or river basin, select the Abundance metric.
Method 2: On the Data Download page, select the ESU for which you want to download data. Select the appropriate metrics and the geographic extent. To find out how many fish there are in a particular population (river basin), check the box for Independent Population on the Spawner Abundance row. If you want data from specific streams or survey sites, click Sites on the Spawner Abundance row.
A. Data are available for Oregon Coast coho, Lower Columbia coho, chinook and steelhead, and Mid-Columbia steelhead. Depending upon the ESU, spawner abundance, persistence, productivity, distribution, diversity, habitat quality, and hatchery fraction metrics can be displayed or downloaded at the ESU, stratum, or population scale. Additional datasets are available for download only including marine survival and harvest data. The Data Download page presents a detailed matrix of what is available.
A. Data provided on this site are either produced by ODFW research offices or used by ODFW in evaluating the recovery or conservation of salmon and steelhead. The majority are from ODFW monitoring projects with the exception of harvest data, which are generated by the Pacific Fishery Management Council (PFMC) using the Fishery Regulation Assessment Model (FRAM). Other data are the result of simulation models
A. It’s great that your community is surveying salmon. Talk with your local Watershed Council about how the information can be used.
To insert a table:
1. All data available here have been reviewed by ODFW research staff and confirmed to be the best available estimates. Automated data validation rules built into the backend database catch certain types of data entry errors; however, the most important data validation procedures are handled by ODFW researchers during the course of data gathering and analysis. The data are first vetted by monitoring project staff upon initial collection and collation. Recovery staff then compile, summarize, and review the data for the purpose of reporting on salmon recovery and conservation. Lastly, a final review of the data is conducted once they are loaded into the online system. Nevertheless, if you find any errors, please contact us immediately.
2. Versioning. Estimates are sometimes changed post-hoc, creating multiple dataset versions. All versions are stored in a database format but only the most recently modified or most current version is provided on the web site. If you wish to acquire a previous version, please contact us.
A. Sign up for notifications. You will receive a message whenever data are added or changed. Most estimates are updated annually, but notices will also be sent as new ESUs or metrics are added during the development phase. We will not provide this email address to any third parties or use it for purposes other than this news service. You may unsubscribe at any time.
