Wetlands of Concern (1/8/2014)
For vector control purposes, ODFW identified wetland types that have a greater conservation concern or are naturally rare. ODFW understands that VCDs treat all wetlands with care and has identified a subset of wetlands across the State to receive an additional level of consideration when being treated for mosquitoes. ODFW relied on the Department of State Lands’ (DSL) definition of Wetlands of Conservation Concern (Appendix E in ODFW's Vector Control Guidance for Sensitive Areas) as well as a selection of wetlands with high conservation significance, as identified by the Wetland Restoration Planning Tool on the Oregon Wetlands Explorer. This tool was jointly developed by The Wetlands Conservancy and the Institute for Natural Resources. 

Wetlands with high conservation significance are those identified with the highest conservation value scores, as determined by the Wetland Restoration Planning Tool. The tool scores wetlands for their current conservation value, summarizing geospatial factors such as: 

- Proximity (100 ft.) to DSL-designated Essential Salmonid Habitat. 
- Occurrence in or 100-ft proximity to USFWS-designated Critical Habitat or within known habitat of USFWS or ODFW-listed or sensitive wetland-dependent   species. 
- Within or adjacent to designated critical habitat and modeled habitat for USFWS or ODFW-listed species. 
- Proximity (300 ft) to a hot spring. 
- Occurrence in an ODFW-designated Conservation Opportunity Area with wetlands or riparian areas designated as a key habitat.
- Occurrence in DSL-designated Wetland of Conservation Concern (formerly Special Area of Concern, SAC).


As a starting point in mapping Wetlands of Concern, ODFW chose a subset of wetlands mapped in the Wetland Explorer with a conservation significance of ≥70. ODFW also removed a category identified as "Potentially Restorable Wetlands". Source wetland data can be accessed at: http://oe.oregonexplorer.info/wetlands/restoration/

As this may not be a real-time list, each County or VCD is responsible for protecting locations covered by federal laws (e.g., raptor nests) that may not be listed by ODFW, should a federally-regulated site be encountered. 


Not all wetlands are mapped. The map displays only those wetlands of high conservation significance, as determined from a wetland prioritization model. Wetland boundaries are derived from National Wetland Inventory and other sources. Many of the wetland polygons were derived only from aerial photo interpretation and may or may not meet wetland criteria in the field.
