About ORBIC's Rare Species Data

INR's ORBIC maintains Oregon's most comprehensive database of rare, threatened and endangered species. This database includes site-specific information on the occurrences, biology, and status of over 2,000 species throughout Oregon. It includes the state's only database of natural vegetation, with descriptions and information on the occurrences and protected locations of all known ecosystem types. As part of the Natural Heritage Network overseen by Natureserve, ORBIC is able to share this data internationally.

ORBIC uses a spatial database called Biotics, the standard for NatureServe partners, that provides information to guide implementation of the Natural Heritage Plan, including the selection of natural areas for registration and dedication. It is also contracted to provide natural heritage and sensitive species information to state and federal agencies, and is accessed daily by public land managers, private developers, researchers and educators.


Electronic systems contain

  • More than 32,500 records of locations of over 1200 species of rare and endangered plants and animals (element occurrences). To see which species we track, check out the Rare Species Lists section of our website.
  • Status of over 900 vertebrate, 1300 invertebrate, 1400 vascular plant, 160 non-vascular plant, 60 alga, and 320 fungus taxa, as well as over 500 plant community types
  • Detailed descriptions of over 820 vertebrate, 50 invertebrate and 300 plant taxa, with ecoregional, county, and EMAP hexagon distributions for vertebrates


Potential questions our data can answer

  • What rare species are known to occur in a given area (county, watershed, legal description, physiographic province, etc.)?
  • Where are the known rare species occurrences located within or near my project?
  • What is its federal and state status?
  • What is the habitat for the rare species that I am interested in?
  • Where are all the known locations in Oregon for a given rare species?

You can find other data resources on the Institute for Natural Resource's Data page.

Making a Rare Species Location Data Request 

Requests for precise rare species location data must be made in writing via email ([email protected]) or regular mail (see contact information below). The following information must be included:

  • Your contact information: name, business/organization name, mailing address, voice and fax telephone numbers, and e-mail address.
  • Type of data needed (PDF report only, or addition of spatial data and which format of spatial data you would like).
  • Locality information for your project. This could be a street address, coordinates, or legal description (i.e. Township-Range-Section), or a spatial layer (shapefile, geodatabase, or Google Earth file) of your area of interest for larger projects. You may also include a map of the project if you like.
  • Project or site name and explanation of how the information will be used.


Time Frame for Response

Data requests are processed in the order in which they are received. The response time is approximately 10 working days, although large or complex data requests may take longer. We may be able to process requests sooner if requested.


What is Included

A typical data request will result in a PDF database report of rare, threatened, and endangered species within two miles of the area of interest. All state or federally listed species are included, as well as any ORBIC List 1 or List 2 species, covering vertebrates, invertebrates, vascular and nonvascular plants, fungi, and marine algae. General locational information (TRS, centroid) is provided as a field in the report. Any population data or habitat information about the occurrence is also included.

Project-specific Data and Databases

INR has numerous project-specific databases that include primary data collection (such as from National Park Service projects) and processed data. Data can be processed numerous ways including: 1) modeled and imputed data, 2) standard GIS and image processing techniques, and 3) database processing. Highlights of recent project-project specific data and databases include:

Sage-Grouse Conservation Partnership (SageCon) Data

SageCon Data. Sage-Grouse Conservation Partnership (SageCon) was convened by the Oregon Governor's Office, the Natural Resources Conservation Service (NRCS), and the U.S. Bureau of Land Management (BLM) in 2013 to proactively address USFWS’ 2015 Sage-Grouse listing decision in 2015. By addressing key threats to sagebrush habitat, SageCon has been working collaboratively with ranching and farming communities in central and eastern Oregon, as well as emerging industries such as mining and renewable energy, to ensure species protection for sage-grouse protection. The goal for the collaborative effort was to develop an “all lands, all threats” plan for sage-grouse conservation in Oregon. Data used for the plan are publicly available.

National Park Service Assessment Projects Datasets

NPS North Coast and Cascades Network. INR has completed or is in the process of completing several vegetation mapping, inventory, and classification projects for the National Park Service (NPS). These datasets are published through the NPS North Coast and Cascades Network website upon final acceptance and publication of the reports and associated data.

INR Modeled and Imputed Data

Integrated Landscape Assessment Project (ILAP) Data, Models, and AnalysesAccess ILAP Data, Maps, Models, and Analyses. Vegetation estimated and structure modeling using models such as random forest, canonical correlation and other imputation methods; or species models using similar tools and data. Examples of this include:

  • Potential Natural Vegetation (PNV) of Oregon and Washington

  • Oregon/Washington arid land vegetation composition and structure

  • Vegetation Dynamics and Treatment (VDDT) models

  • ILAP VDDT modeling results and crosswalks from modules

  • VDDT modeling strata2 grids and other strata grids to link to model output

  • Arizona/New Mexico vegetation composition and structure – Forest, Arid and Woodlands

  • Endangered species probability of occurrence models for Oregon species. Completed taxa include 8 plants from the coast range, Willamette Valley and Klamath Falls and Fender’s blue butterfly

Willamette Water 2100 Project. Simulations of water supply and demand under various climate and population growth scenarios developed with couple human and natural systems model.  Developed as part of a National Science Foundation project focused on water scarcity.


GIS and Image Processing

Data can be processed using standard GIS operations and image processing techniques. There are numerous raster based datasets that are used to evaluate land use and cover. These raster databases typically represent one point in time and are from aerial photography or from Thematic Mapper imagery. These have been used (in conjunction with other data) to map current vegetation in the Portland metropolitan area through image classification, etc. Details of these data are provided in next section.

Database Processing

Numerous GIS database have complex data designs that require database management and modeling to build geographic databases. INR staff utilizes database management systems including Oracle, SQL/Sever and Access to programmatically build specific databases. One example includes soils, which have variable depths and numerous attributes. Specific database programs have been used at INR to build depth dependent data sets. For instance, for input into global climatic models, we developed programs to build databases for the 3 separate soils profiles (top 50 cm, 50 to 200 cm, and below 200 cm) for primary attributes including (see Appendix A for complete list):

  • Available water capacity
  • Percent sand

These programs have been modified to build output that provide depth integrated (one number representing the entire profile) for other soils characteristics such as natural drainage, etc. In addition, there are numerous GIS databases which are temporal in nature and continuously changing. These event based datasets typically maintain a base GIS coverage with linkage to on-line data systems.

Event-based Data

INR uses numerous data sources that identify the specific location in time and numerous attributes associated with the event. Examples of this include many point/sample locations where on-going data collection is occurring. These databases require specialized database programming and mapping techniques. This includes common and updated linkages to online time series data collection activities, specifically including:

  • USGS NWIS Daily Value Data (Discharge; Daily Averaged Real Time Data) — The USGS National Water Information System (NWIS) provides access to millions of sites measuring streamflow, groundwater levels, and water quality.
  • EPA STORET(STOrage and RETrieval) — STORET is a repository for water quality, biological, and physical data and is used by state environmental agencies, EPA and other federal agencies, universities, private citizens, and many others.

Historical Vegetation in the Pacific Northwest

Creating Historical Vegetation Maps. Land managers and researchers often want to know what a landscape looked like years ago to compare how the ecology has changed, assess the rate of change, and make decisions about how to manage the area for the future. ORBIC and its partners have created datasets of historical vegetation at both fine and coarse scales, using several different data sources. Read more and view coverages by clicking below:

Available Historical Vegetation Maps. Historical vegetation maps available for download include: 

National Park Service Vegetation Maps. In conjunction with NatureServe, INR made updated remote sensing-based vegetation maps for the major national parks in the Pacific Northwest. Detecting climate change impacts on the distribution of vegetation requires an accurate map of baseline conditions made using a repeatable methodology. The National Park Service Inventory & Monitoring Program embarked on a major vegetation mapping project for Mount Rainier, Olympic, North Cascades, and Lewis and Clark National Parks.

The new vegetation maps used the recently revised National Vegetation Classification System. They are targeted to the Alliance level, roughly equivalent to dominant canopy species with some major types further differentiated by temperature or moisture modifiers. Multi-temporal Landsat TM imagery, supplemented by color-infrared aerial photography, LiDAR elevation and vegetation height data where available, and extensive field training data collection, form the basis of the mapping, which was performed using Random Forests data mining techniques. The maps provide a baseline against which to measure vegetation change and provide useful inputs for studies of the impacts of climate change on a variety of vegetation processes, including carbon dynamics and disturbance.

Final products are available from the National Park Service website at their Natural Resource Reports page.


Interactive Mapping 

Oregon Explorer. With hundreds of map layers available to draw from, you can use the Oregon Explorer Map Viewer to make your own custom map and share it with others. 

Oregon Water Atlas (Institute for Water and Watersheds). This interactive site include visualizations of Oregon water data created entirely with open-source software and publicly available data. OSU student Gareth Baldrica-Franklin created the atlas as part of his undergraduate honors thesis.


Land Ownership

Land Ownership, Management, and Protected Areas. Starting the Oregon Gap Analysis Project, the Oregon Biodiversity Information Center has been developing and maintaining a GIS coverage showing the distribution of Protected Areas in Oregon for many years. USGS GAP status is used to easily classify managed areas as being protected primarily for biodiversity verus lands without biodiversity protections (GAP status of 1 being most protected, 4 being not protected). Several other designations and descriptions are included in the datasets, covering federal, state, local, and private managed lands as available. The stewardship coverage is continually updated as new areas are protected or designated, or as land ownership patterns change.

Three Oregon managed area datasets are available from ORBIC:

  • The Oregon Protected Areas dataset (PAD-US) is similar to the Stewardship geodatabase but conforms to USGS standards (i.e. Oregon-specific fields are removed) and is available from the PAD-US data download page. USGS also adds additional protected areas, recreation areas, and open spaces based on submissions from national partners. ORBIC periodically provides Oregon updates to the PAD-US, and USGS and its partners are making continual improvements to the national dataset. 
  • The Oregon Stewardship geodatabase (download) (2015) includes layers for managed areas and easements. Managed areas include a variety of classifications including wilderness areas, nature preserve, marine reserves, and wildlife management areas. Last updated in November 2015. 

Several other public land coverages are available at the Oregon GEOHub


Vegetation and Habitat Maps

Oregon Statewide Habitat Map. This is a map of Oregon's 77 habitats created in 2018, based on 2016 imagery. The map is to be used to help map the distribution of wildlife habitat in Oregon, and is a reflect of current vegetation conditions across the state. View metadata and download map.

Rangeland Vegetation Maps and Tools. INR is working with many collaborators to develop rangeland vegetation maps and tools to support the SageCon Partnership to reduce threats to the sagebrush ecosystem, sage-grouse and ranching communities in Oregon.

Integrated Landscape Assessment Project Maps. The Integrated Landscape Assessment Project for Oregon, Washington, Arizona, and New Mexico produced many vegetation maps and datasets for Oregon, including existing vegetation and forest structure as well as predicted vegetation based on various management and climate states.

NW ReGAP Ecological Systems Map of Oregon. In the 2000s ORBIC received funding from OWEB to integrate all available 1:24,000 vegetation maps and coverages. Previously, the only statewide vegetation or land coverages available for Oregon had been the two OR-GAP coverages described below. ORBIC and OR-GAP has worked hard to link all existing vegetation coverages to the National Vegetation Classification System. The newest version of the map (download), a grid of ecological systems throughout Oregon, was created in 2010. 


Water Quality Map

This map highlights water pollution issues in the Willamette River system. It was produced by the Corvallis Environmental Center and the Institute for Water and Watersheds and published in August of 2008. The map can be downloaded as a PDF -- map front, descriptive text from map back. Additional resources can be found at Willamette River Basin resources from the Institute for Water and Watersheds.



Oregon Wetlands Cover. The Oregon Wetlands Cover represents the most comprehensive dataset available for the location and composition of the state's wetlands. It uses as a base all available digital data from the National Wetland Inventory (NWI; U.S. Fish and Wildlife Service, USFWS), to which has been added draft NWI mapping (Oregon Natural Heritage Information Center and The Wetlands Conservancy, ORNHIC and TWC), mapping from Local Wetland Inventories (LWIs; Department of State Lands, DSL), wetlands along state highways (Oregon Department of Transportation, ODOT), and mapping of individual sites by a variety of federal, state, academic, and nonprofit sources. Download map description and data layer.

Oregon's Greatest Wetlands. Oregon has lost over half of the wetlands present when the first settlers arrived in the 1800s. To ensure that the remaining wetlands are conserved, The Wetlands Conservancy has identified Oregon's Greatest Wetlands. While all wetlands are important, Oregon's Greatest Wetlands identifies the most biologically significant wetlands in Oregon. A group of twenty wetland ecologists, familiar with the entire state of Oregon, identified the locations of the biologically important wetlands. The next step was collecting and adding information for wetland resources identified by the Oregon Natural Heritage Program, National Wetlands Inventory, Coastal, Klamath and Willamette Valley Sub Basin Plans, and Oregon Biodiversity Program. Wetland ecologists were then asked to review and add to the maps. Simultaneously we collected existing physiographic and biological information about each of the sites. Download map description and data layer.
