potential yield, soil characteristics, end the significance end similarity of this field to true AVFS in the regi or.. The Annend field has not been hayed since the late 7950s with •' the exception of a small amount of hay which was cut out of the center portion of the field about five years ego (Carolyr~ Moon, personal communication, 1995). There has been no reseeding of the field or indication of normal husbandry practices being applied as evidenced by the dominanee• of reinvrrding native species. Discussions with individutils familiar with the area indicate only loose-stacked grass hay was harvested when the pasture was hayed (Beryl Rienks, Don Zulian, Bud Zabel, 1995). They also indicate not much hay was produced, possibly only enough to supply Mr. Annand's single milk cow with enough hay through the winter. Peabody purchased the A•nnand property in 1986, but had leased the property for approximately 20 years prior to 1986. No one, with the minor exception noted above, has approached Peabody about haying this field or managing it as a separate unit for hay production. Ms. Noon, a local livestock operator, had leased the area for grazing a number of years. She stated production in the field drops off later in the summer and, if hayed, may only produce one cutting of hay. Additionally, she stated livestock water from • the gravity flow source near the cabin (upper end of the field) becomes limiting later in the grazing season and an additional management problem. In her opinion, the field does not provide enough potential hay production, is too small in area, and is too remote in relation to a base of operations to warrant the expense and effort of haying. Based on the Division's concern for a potential AVF determination for the area in question, the field mapping was refined using i"=200' scale 5-foot contour topographic maps and a number of black and white and color photographs of generally a 1"=1000' state. Additionally, one frame of 1'~=1000' scale color IR photography (8/25/87) was available showing approximately the upper half of the field. initially, it was reported to the Division that 22 acres were included in the field within Annand Draw. The actual acreage is much less because the 22-acre number was determined by errantly including the acreage from an AVF located in upper Sage Creek which was included in the vegetation sampling. The more intensive analysis of the aerial photography and the refined mapping shoos the maximum acreage, which is influenced by some degree of subirrigetion, is 70.9 acres. However, small portions of the field are consistently lighter colored in the black and white and color aerial photography, indicating subirrigation is not strongly influencing • vegetation conditions throughout this field. Further evidence comes from the color IR 14 Revised 03/24/95
