Table 1-2 provides a brief summary of all species on both the USFWS listing of species within Jackson County (USFWS 2010) and Oregon Department of Agriculture’s (ODA) listed plants in Jackson County (ODA 2010). A summarization of geographic extent is also presented to clarify occurrence within the action area or project footprint:

Occurs Within Action Area?
|
Vernal Pool Fairy Shrimp
|
DCH: Within vernal pool complexes (VPCs) in Agate Desert region. Typically the majority of pools in any VPC are not inhabited by the species at any one time. Different pools within or between complexes may provide habitat for the fairy shrimp in alternative years, as climatic conditions vary. Within the project area, Agate Road north of the existing OR 62 intersection; Agate Road centered on Touvelle Road; and the existing Highway 62 alignment just south of the West Dutton Road.
|
Yes
|
Cook’s Lomatium
|
DCH: Within the Agate Desert only where soil types have a hard pan or clay pan layer close to the soil surface, creating seasonally wet soils and vernal pools. Found in communities with lack of trees, sparse prairie vegetation, and agate on the soil surface. Grasslands and VPCs within the southeastern and eastern boundary of the Rogue Valley International -Medford Airport (Airport) property, an area across the Medco Haul Road between Aviation Way and Commerce Drive, an area at the northern end of the runway on Airport property, south of Vilas Road and just west of Upton Slough, and an area between East Gregory Road and Antelope Road, just west of Agate Road.
|
Yes
|
Large-Flowered Woolly
Meadowfoam
|
DCH: Within the Agate Desert region, occurs at the edge of vernal pools at elevations of 1,230 to 1,310 feet, generally near the wetter, inner edges. Grasslands and -VPCs between East Gregory Road and Antelope Road, just west of Agate Road, and an area surrounding the west end of West Dutton Road, just north of the Veterans Affairs Southern Oregon Resource Center and Clinics (VA SORCC).
|
Yes
|
Gentner’s Fritillary
|
Not Designated: Typically grows in or on the edge of open woodlands at elevations from 60 to 450 feet with Oregon white oak (Quercus garryana) and Pacific madrone (Arbutus menziesii). Can also grow in open chaparral/grassland habitat, which is often found within or adjacent to the mixed hardwood forest type, but always where some wind or sun protection is provided by other shrubs.
|
No
|
Southern Oregon
Buttercup
|
Not Designated: Endemic to central Jackson County. Occurs in oak savannas on the lower south flank of Upper Table Rock, but has not been found on Lower Table Rock.
|
Yes
|
Kincaid’s Lupine
|
Designated CH: Found mainly in the Willamette Valley, but ranges south to Douglas County. Occupies native grassland habitats. Typically found in native upland dry fescue prairies and on well-developed soils adjacent to serpentine outcrops (high in magnesium, iron and certain toxic metals) often under scattered oaks.
|
No
|
Siskiyou Mariposa Lily
|
Not Designated: Found near Bald Mountain in Jackson County, but an extirpated population once occurred on Red Mountain near the Oregon–California Border. Open rock outcrop barrens associated with Ponderosa pine, ocean spray, Idaho fescue and wild buckwheat species.
|
No
|
|
Coral Seeded Allocarya
|
Not Designated: Open areas in low-lying wet meadows that dry in summer. Restricted to the Upper Rogue River Valley in Jackson County.
|
No
|
|
For the purposes of this assessment, only three ESA-listed species have been addressed: VPFS, Cook’s lomatium and large-flowered woolly meadowfoam. These three species have both known occurrences of individuals within the action area and project footprint and also have known suitable habitat (mound-vernal pool complexes) within the project footprint.
Gentner’s fritillary, Kincaid’s Lupine, Siskiyou Mariposa Lily and Coral Seeded Allocarya are not known to occur within the action area and suitable habitat, as described above, is not known to occur within the action area (pers. Communication Sam Friedman, FWS Regional Biologist, March 2011). Southern Oregon Buttercup is known to occur within the action area in areas of suitable habitat; however, no suitable habitat or occurrences of buttercup were identified during field surveys (MB&G 2008).
