1-5:Aurora Donald Interchange(Exit 278) Interchange Area Management Plan for Marion County Approval ODOT KN19062 Oregon Department of Transportation—Region 2 camping and commercial and light-industrial development.The agricultural fields consisted of a low grassy groundcover in the northwestern quadrant of the study area (Photo 1 in Appendix E) and unidentified tree saplings amongst low grassy groundcover in the northeastern quadrant (Photos 2 and 3 in Appendix E).A small grove of hardwood and conifer trees was present between the field and 1-5 in the northeastern quadrant. The fields in the southeastern quadrant consisted of low grassy groundcover, while the drainage area of the tributary to Seneca) Creek appeared to be dominated by Douglas-fir (Pseudotsuga menziesii), invasive English ivy (Hedera helix), and Armenian (Himalayan) blackberry (Rubus armeniacus) (Photos 4 and 5 in Appendix E). A small grove of 24-to 36-inch-diameter Douglas-fir trees is located adjacent to the RV resort(Photo 6 in Appendix E). Much of the southwestern quadrant consisted of developed areas with ornamental vegetation and grassy lawns. 2.4.4.2 Special Status Species A review of existing information related to fish and wildlife distribution and habitat within and surrounding the study area included the following: • USFWS Information Planning and Conservation (IPaC) database—Trust Resources Report • USFWS Environmental Conservation Online System (ECOS) Critical Habitat for Threatened and Endangered Species • StreamNet: Fish Data for the Northwest Interactive Mapper In addition, the Oregon Biodiversity Information Center (ORBIC) produced a database search for rare, threatened, and endangered plant and animal records for species that may occur within a 2-mile radius of the study area.The ORBIC database search showed two federally listed species: Upper Willamette River(UWR) Chinook salmon (Oncorhynchus tshawytscha) and UWR steelhead (O. mykiss). The ORBIC database search revealed three special status species recorded within a 2-mile radius of the study area: • Western painted turtle (Chrysemys picta bellii)—Federal: None; ORBIC:Sensitive-Critical • Oregon giant earthworm (Driloleirus macelfreshi)—Federal: Species of Concern; ORBIC: Sensitive9 • Fungus (Tuber quercicola)—Federal: None; ORBIC: Review Based on the off-site data collection efforts and a January 22, 2019, site visit to assess species presence and habitat conditions within the study area, suitable habitat for Oregon special status species is not present within the study area, and no State of Oregon special status species are known or expected to occur in the study area. There are no critical habitats designated within the study area, and no ESA-listed species occur in the study area (see Table 1 in Appendix E). Consultation with the National Marine Fisheries Service through the Federal Aid Highway Program programmatic biological opinion process will be required.The consultation would consider potential effects due to changes in base and peak stream flows caused by new impervious surface and potential impacts to water quality within the study area as well as in waters downstream of the study area discharges (including Seneca) Creek, Mill Creek,the Pudding River,the Willamette River, and the Columbia River). 9 The status of Oregon giant earthworm and the fungus Tuber quercicola are from those listed in the ORBIC(2019) report. Recent reclassifications show no official status for these species,other than federal species of concern and ORBIC status of "Threatened or Endangered throughout Range"for the earthworm,and ORBIC status of"Review"for the T. quercicola (ORBIC 2016).
