Oregon Measure 49 Analyzer

The purposes of the Measure 49 Analyzer are to provide Measure 49 property owners with tools to search for a Measure 37/49 claim property by election number, claim name, or interactively from the map; view authorized Measure 37/49 claim property boundaries and the numbers of new dwellings, new parcels, and total home sites authorized by the final order; find and download a “Final Order and Home Site Authorization”; view simplified maps of areas that are high-value farmland, high-value forestland and ground water restricted as specifically defined in Measure 49; and calculate and create a downloadable report of the percentages of high-value farmland and high-value forestland area within a claim property.

Oregon Urban Growth Boundary History Map

View changes to Urban Growth Boundaries through time.


Oregon Sage-Grouse Development Registry Viewer

As part of the SageCon partnership, Oregon committed to limiting the amount of human development within sage grouse core habitat in an effort to conserve the species. On September 16, 2015, Governor Brown signed Executive Order 15-18 which directed the OR Dept. of Land Conservation & Development (DLCD) to maintain a central registry of development on all lands within sage grouse habitat in coordination with the Bureau of Land Management (BLM) and county governments. The central registry must use the adopted baseline level of development within each Priority Area for Conservation (PAC) and track the location and extent of new development in each PAC over time.

Oregon Administrative Rule (OAR) 660-023-0115 identifies significant sage grouse habitat and directs counties to apply a hierarchy of mitigation to land use proposals. The rule also establishes a metering mechanism that allows only 1% of each PAC to be developed per 10-year increment, and establishes a hard ceiling that would not allow human-caused development to ever occupy more than 3% of any PAC. This tool shows the human development within the sage grouse PACs. Users can run a report to see the amount of development relative to the 1% and 3% development thresholds.

Oregon Sage-Grouse Data Viewer

The Sage-Grouse Data viewer is an Oregon Explorer web-based mapping application that allows the public to access up-to-date data layers related to Sage-Grouse habitat and threats in Oregon. Users can view data for the entire Sage-Grouse range in Oregon, or navigate to their location of interest, while advanced users can download data for analysis. The Viewer includes a suite of theme-based scores that rate areas across eastern Oregon by their habitat viability, fire and invasives threat, biodiversity significance, and energy development potential. Each theme consists of multiple indicator datasets which are also included in the Viewer. Supplemental data layers are included in the Viewer such as vegetation condition, previous wildfire perimeters, seasonal sage-grouse habitat, and sage-grouse habitat management boundaries.

Watershed Restoration

Oregon Watershed Restoration Tool

Access restoration project information and download data for Oregon Plan basins, subbasins or watershed councils. This tool was created in partnership with the Oregon Watershed Enhancement Board (OWEB) to show the locations of and information from the Oregon Watershed Restoration Inventory (OWRI) Database and Fish Passage Inventory data.

Oregon Watershed Restoration Reporter Tool

Use this tool to report on total number of restoration projects and investments for Oregon and it's basins, subbasins, counties and watershed councils for a time period selected by the user. Includes bar charts, pie charts and funding reports and outcomes for instream, riparian, fish passage, road, upland, wetland, estuarine, urban, fish screening and instream flow restoration activities.

OWEB Investment Tracking Tool

This tool allows you to explore how OWEB grant funding is distributed across the state. The tool provides basic information on grants in progress and those that have been completed (e.g. project name, start year, OWEB funding amount). The Oregon Watershed Restoration Inventory provides more detailed information on completed restoration projects


Willamette Valley Wetland Prescreening Tool

Identify mapped wetlands, water bodies, rare wetland types, and federally-listed species that may occur in, or within 100 feet of, your project area within Oregon's Willamette Valley. Multiple wetland-related data layers are available for mapping.

Oregon Wetland Restoration Planning Tool

Locate the most appropriate sites to implement restoration within a given watershed (watersheds are typically 4th level, 8-digit HUCs). The Oregon Wetland Restoration Planning Tool strives to identify which wetland complexes are the best to restore, based on current wetland condition, land management status, suitable soils, hydrology, and proximity to existing restoration projects, and also what plant materials to use for the job.

Oregon Rapid Wetland Assessment Protocol (ORWAP) Map Viewer

The Oregon Rapid Wetland Assessment Protocol (ORWAP) is a standardized method for rapidly assessing the functions and values of wetlands. The ORWAP tool provides site-specific mapping and reporting information needed to answer a small but important subset of ORWAPs 140 indicator questions. It also allows ORWAP users to upload completed assessments. The entire ORWAP protocol (manual, spreadsheets, data forms, policy guidance) can be viewed or downloaded from the Department of State Lands website. 

Wildlife, Biodiversity, and Invasive Species

Oregon Wildlife Viewer

The Oregon Wildlife Viewer is a tool to get specific wildlife species information for amphibians, birds, mammals and reptiles and generate species lists for places in Oregon.

Oregon Biodiversity Map Viewer

Obtain meaningful information about important, sensitive, rare and listed forest species and habitats that could be found, or restored, on a landowner's property.  View species and ecological systems data aggregated to the 6th field watershed, and gain easy access to the species status with respect to distribution or rareness, as well as a measure of the watersheds importance to maintaining populations of that species or habitat.


iMapInvasives is an online, GIS-based invasive species reporting and querying tool. It is focused on the need for land managers, regional planners, and others who are working to prevent, control, or manage invasive species to have locational information for where invasive species can be found. To access point distribution maps, view detailed observation records, enter sightings online, run reports and queries, and otherwise take full advantage of the iMapInvasives site, you will need to sign up for a free login. More information about iMapInvasives can be found at the iMapInvasives informational website.
