;toeck~i2-kearnrn~rz~2 & assocscrt~s ~C0~.O91CC7~ COI2SU~~QT2~S I-14 August 17, 1981 , Mr. Jay Stewart Flatiron Companies P.0. Box 221 Boulder, Colorado 80302 Dear Jay, On August 15, 1981, I visited the Bourg Property and examined the vegetation along Mann Draw and the other drainage which crosses the site. Specifically. I was looking for areas which may support subirrigated vegetation. There is no evidence that any of the vegetation along either of these two drain- ages is subirrigated. The vegetation along the draws is composed of a big sagebrush shrubland type which is essentially the same as that which grows on the uplands adjacent to the drainages. There are no grassy meadows or grass-lined channels. The sagebrush is continuous from the uplands on one side of the drainage to the uplands on the other. The whole area consists of undeveloped rangeland. '. I also visited the Load Out facility at North Gate on August 15, 1981, The original vegetation at this site was probably a shrubland type dominated by silver sagebrush (Artemisia canal. The original vege- tation has mostly been removed or altered by past activities at the site. There is a road which crosses the entire area, and there is evidence that the site has been used in the past as a stockpile site for shipping coal. Old coal fragments occur over parts of the site. Currently, much of the area supports only a sparse cover of vegetation. Based on observations adjacent to the permit area, the original vegetation was probably dominated by silver sagebrush, rubber rabbitbrush (Chrysothammcs nauseosus), big sagebrush (Artemisia tridentata), and western wheatgrass (Agropyron smithii), The vegetation is similar to that on the Bourg property, however, the presence of silver sagebrush and rubber rabbitbrush make it somewhat different in that the type is likely to be more productive than the vegetation on the mine site. If you have any questions about either of these two sites, please give me a call. Best regards, Warren R.
