Box 1990, Carbondale, Colorado 81623 1 Seaton Subdivision Vegetation and Wildlife November 2009 Purpose This document provides information and guidance regarding pertinent vegetation resources and wildlife on the portion of the Seaton Property proposed for a property split or subdivision. The Seaton property is located along Four Mile Road (CR117) roughly three and a quarter miles south of Glenwood Springs and up the Four Mile Creek watershed. This property lies just south of Chelyn Road off of Four Mile Road and includes a section of Four Mile Creek approximately two plus river miles upstream from the confluence of Four Mile Creek and the Roaring Fork River. The elevation is roughly 6,320 feet at the east edge of the Seaton property along Four Mile Creek Road dropping down slightly to the creek bottom to the west. This area extending from the road to the creek consists of the eastern half of the existing Seaton property and is now proposed as a separate lot (See Map 1, Seaton Proposed Subdivision, Weed areas of Note) . Brief Description of the Property The 4.448 acre piece of the Seaton property that is being proposed as a separate parcel is comprised mainly of a riparian plant community, an adjacent remnant of the original native upland Gambel oak/serviceberry community, and cleared meadow areas up on a higher terrace, now consisting of cultivated Eurasian pasture grasses. The other half of the property, 8.6 acres with the existing house, comprises the western half. It consists mainly of an un­ manipulated native, upland, mixed-mountain shrub plant community extending uphill above the existing
