Terrestrial Species of Concern

Definition: Prioritizes areas based on species of state and/or national conservation importance, including those vulnerable to extinction or those undergoing regional decline or other species requiring special management attention. Emphasis placed on high priority species such as Federal or State Threatened or Endangered; candidate species for listing status; and Oregon Conservation Strategy species.

Aggregation method: An ODFW created prioritization rule-set was developed to prioritize areas based on results found within data sources. High priority values are dependent upon documented observations of high priority species or ODFW Sage-Grouse Core Areas. Lower priorities were established from overlaying modeling data. Additional details:

  • Observation data were filtered to not include any observation prior to 1975, and observations do not include fish species (which are accounted for within the Aquatic Species of Concern layer.)
  • Oregon Conservation Strategy (OCS) GAP Overlay values were calculated by overlaying all available terrestrial vertebrate OCS species distribution models analyzed within the USGS GAP Distribution Models project. The OCS GAP Overlay Value simply corresponds to the number of models that are found to be within a given area.
  • More information on the Oregon Conservation Strategy, including a list of strategy species.. Many of these species are also designated as state sensitive species.
  • Federal or State status and species lists used in this analysis can be found on the Oregon Biodiversity Information Center website.

Priority Rank Definitions

Priority 1: At least one of the following has been documented in this area:

  • Documented observation of a Federal Threatened or Endangered species (including Candidate species)
  • Documented observation of a State Threatened or Endangered species
  • Documented observation of an Oregon Conservation Strategy species (observed within the listed eco-region) that also holds a NatureServe state rank of “S1” (critically imperiled within the state of Oregon)
  • Oregon Department of Fish and Wildlife (ODFW) Sage-Grouse Core Area

Priority 2: At least one of the following has been documented in this area (and no species documented from the Priority 1 list):

  • Documented observation of any Oregon Conservation Strategy species (observed within the listed eco-region) that holds a lower NatureServe state rank than “S1” (critically imperiled within the state of Oregon)
  • Documented observation of a Federal Species of Concern
  • ODFW Sage-Grouse Low-Density Area

Priority 3: At least one of the following has been documented in this area (and no species documented from Priority 1 or 2 lists):

  • Species with a NatureServe state rank of “S1” (critically imperiled within the state of Oregon)
  • Species with a NatureServe state rank of “S2” (imperiled within the state of Oregon)
  • Additional state priority species: species protected under the Bald and Golden Eagle Protection Act (Bald Eagles, Golden Eagles); all bat species; American Pika

Priority 4: At least one of the following has been documented in this area (and no species documented within Terrestrial Species of Concern Priority 1, 2, or 3 lists):

  • Species with a NatureServe state rank of “S3” (rare, uncommon, or threatened but not immediately imperiled)
  • Highest class of Terrestrial Vertebrate OCS GAP Overlay Values: 48-33 species distribution models

Priority 5: No species documented within Terrestrial Species of Concern Priority 1, 2, 3, or 4 lists. Contains second highest class of Terrestrial Vertebrate OCS GAP Overlay Values: 32-27 species distribution models.

Priority 6: No species documented within Terrestrial Species of Concern Priority 1, 2, 3, 4, or 5 lists. Contains lowest class of Terrestrial Vertebrate OCS GAP Overlay Values: 26-5 species distribution models.

Input Layer Definitions

Species Priority Rank: Designates the priority rank established from a documented species observation. Definitions for values 1 through 4 can be found in the Terrestrial Species of Concern priority rank definitions. Value 9999 indicates that as of the last data update, no observations of a species of concern have been recorded.

ODFW Sage-Grouse Core Areas: Designates that an ODFW Sage-Grouse Core Area has been documented. A value of 1 indicates documentation of an ODFW Sage-Grouse Core Area. A value of 2 indicates documentation of an ODFW Sage-Grouse Low Density Area. A value of 9999 indicates no Sage-Grouse Core Area has been determined in this hexagon.

See the Greater Sage-Grouse Conservation Assessment and Strategy for Oregon.

OCS Gap Species Distribution Models: Provides the results of the Oregon Conservation Strategy (OCS) GAP Overlay analysis, which was calculated by overlaying all available terrestrial vertebrate OCS species distribution models analyzed within the USGS GAP Distribution Models project. The value presented here corresponds to the number of models that are found to be within a given area.

ODFW Sage-Grouse Core Areas

The Sage-Grouse Core Area maps and data were developed as one component of the ODFW Conservation Strategy for sage-grouse in Oregon.

Bald Eagle Breeding Surveys in Oregon

Bald Eagle nests and breeding outcomes monitored within Oregon and along the Lower Columbia River from 1971 to 2010.

US Fish and Wildlife Service and Oregon Eagle Foundation

Golden Eagle Breeding Surveys in Oregon

Summary of Golden Eagle observations throughout the state of Oregon. Observations have been compiled from records between 2011 and 2012. These records were compiled from a wide range of sources over a 2 year timespan and are by no means complete. The breeding area records here do not necessarily represent nest locations.

ODFW Herptile Observations

Monitoring of amphibians was conducted in coordination with ODFW aquatic habitat and fish surveys. Observations and captures occurred between 2007 and 2010, and the data is reported as presence only.

ODFW Scientific Take Permit Reports

Reports provided to ODFW from approved applicants within the ODFW Scientific Take Permit Program. All applicants must submit a report providing locations of species observations or contact. These reports are then compiled into a single database, and provide a good source for additional wildlife observation data.

ODFW Washington Ground Squirrel Observations

This data set is a compilation of several sources depicting Washington Ground Squirrel activity, which includes formal surveys of burrow locations from ODFW and private contractors, general centerpoints for colonies, and incidental sitings. Dates of locations observed range from 1979 to January, 2013, and may have been monitored once or several times over this time period.

Oregon Turtle Survey Data

Turtle observations and mark and recapture studies monitored in Oregon, compiled from a variety of sources and maintained by Oregon Department of Fish and Wildlife (ODFW). Observation dates range from 1979 to January, 2013, and areas may have been monitored once or several times over this time period.
