1. Oregon Chub (oregonichthys crameri) Critical Habitat Designation Chris Cusack Judith Dempsey Biao Huang Tae-Young Kim Caiwen Wu

2. Objective This project will investigate the potential economic impacts of designating critical habitat for the Oregon Chub on the commercial, agricultural, industrial, and recreational sectors, over and above those impacts already made by it’s classification as an endangered species.

3. Overview Oregon Chub – description and background Endagered Species Designation vs. Critical Habitat Economic Analysis Conclusion

4. The Oregon Chub is a small, minnow-like fish which favor backwaters with little or no current, silty and organic substrate, and ample vegetation for hiding

5. Historic habitat The Oregon Chub is endemic to the Willamette valley of Western Oregon formerly distributed throughout the Willamette River Valley in a dynamic network of off-channel habitats

6. Historic Distribution of Oregon Chub in the Willamette River Basin (from Markle 1991/Oregon Chub Recovery Plan)

7. Changes in Habitat Conditions Alterations in natural flow conditions –Dams –Flood control projects –Fill and removal activities –Etc. Decline in Water Quality Introduction of non-indigenous species (NIS)

8. Willamette River – Past and Present (Sedell and Froggatt 1984/Oregon Chub Recovery Plan)

9. 1998 Distribution of Oregon Chub in the Willamette River Basin (Oregon Chub Recovery Plan)

10. Oregon chub potentially occurs in these Oregon counties: Benton, Lane, Linn, Marion, Polk (Map may reflect historical as well as recent sightings) Map from http://www.fws.gov/oregonfwo/Species/Data/OregonChub/

11. Endangered Species Act (ESA) Purpose: protect and recover imperiled species and the ecosystems upon which they depend Endangered species: any species which is in danger of extinction throughout all or a significant portion of its range. Threatened species: any species which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range. http://www.fws.gov/endangered/pdfs/esaall.pdf

12. Criteria used to evaluate the listing of a species 1)damage to, or destruction of, a species’ habitat 2)overutilization of the species for commercial, recreational, scientific, or educational purposes 3)disease or predation 4)inadequacy of existing protection 5)other natural or manmade factors that affect the continued existence of the species

13. Critical Habitat The term “critical habitat” for a threatened or endangered species means: –the specific areas within the geographical area occupied by the species, at the time it is listed, on which are found those physical or biological features essential to the conservation of the species and which may require special management considerations or protection; and –specific areas outside the geographical area occupied by the species at the time it is listed, upon a determination by the Secretary that such areas are essential for the conservation of the species. Critical habitat may be established for those species now listed as threatened or endangered species for which no critical habitat has heretofore been established Except in those circumstances determined by the Secretary, critical habitat shall not include the entire geographical area which can be occupied by the threatened or endangered species

14. ESA and the Oregon Chub The Oregon chub was listed as endangered in 1993. A recovery plan was published in 1998. A 5-year review was published in 2008 Currently, there is a proposal to designate critical habitat for this species.
