Description
- Abstract: The Pacific lamprey has inhabited the rivers, streams and coastal waters of the west for 350 million years (BPA, 2005). These data describe areas of suitable habitat currently and historically used by Pacific lamprey populations. Pacific lamprey, Lampetra tridentata, (more recently identified as Entosphenus tridentatus), are native to the Pacific coast from Baja California to the Bering Sea. They are anadromous, migrating from their natal stream to the ocean and back, but unlike salmon, Pacific lamprey spend well over half of their total life cycle in freshwater. The Pacific lamprey was listed as an Oregon State sensitive species in 1993 and in 1996 was protected through restriction of harvest (ODFW 2006).
These data now comply with the Oregon Fish Habitat Distribution Data Standard that was adopted by the Oregon Geographic Information Council in February 2011. The Standard document can be found at: http://gis.oregon.gov/DAS/EISPD/GEO/standards/docs/OregonFishHabitatDistributionDataStandardv2.pdf The term "currently" is defined as within the past five reproductive cycles. This information is based on sampling (see the fhdBasis field). Due to natural variations in run size, water conditions, or other environmental factors, some habitats identified may not be used annually.Habitat distribution data are mapped at a 1:24,000 scale statewide and are based on the Pacific Northwest Framework Hydrography dataset. The data are made available as GIS files in both shapefile and ESRI geodatabase format. The data were developed over an extensive time period ranging from 1990 to 2011. Data were migrated to the NHD in Spring of 2014.
-
- Purpose: To provide an inventory of Pacific lamprey habitat distribution in Oregon for documentation, mapping and analysis.
-
- Time Period of Content: 1990 - 2014
- Geographic Extent: Oregon
- Status: Final
- Use Constraints: This dataset inevitably ommits some areas of habitat that were not known at the time the information was collected. As information on Pacific lamprey habitat distribution improves it will be incorporated into future versions of this dataset.
- Format: ArcGIS version 10 file geodatabase and also shapefile.
Data Quality Information
- Lineage-Source: Pacific lamprey observation data was obtained from (1) US Bureau of Land Management as a geodatabase feature class in March 2011, (2) the Life Cyle Monitoring Project, as a table with trap coordinates in April 2011, (3) Native Fish Investigations, Corvallis Research Lab, as a geodatabase feature class in April 2011, (4) the Siletz Tribe as a shapefile, in May 2011, (5) Oregon Adult Salmonid Inventory and Sampling Project, (OASIS), as an Excel spreadsheet in June 2011, (6) Umpqua and Umatilla National Forests as shapefiles in July 2011, (7) the Grande Ronde Tribe as an Excel spreadsheet, with tracking kilometer measures, in September 2011, and (8) from a Fisheries report and Bear Creek Watershed Council report in September 2011. Based on survey data and supporting documentation, habitat distribution data along with associated attributes were developed by ODFW GIS staff. The data utilize the linear referencing model and are stored as event tables based on the Pacific Northwest Framework Hydrography 1:24,000 scale stream network. Also, a file geodatabase has been added in July 2014 that contains pacific lamprey data that have been migrated to an April 2014 version of the National Hydrography Dataset (see file with "nhd" in the name).
