In response, CNHP has searched it's Biological and <br />Conservation Datasystem for natural heritage resources (occurrences of significant natural <br />communities and rare, threatened or endangered plants and animals) documented from: <br />T12S R90W Section 31 <br />T13S R90W Sections 1-12, 17 <br />T12S R91 W Sections 34-36 <br />T13S R91W Sections 1-3, 11-13 <br />Our records indicate the occurrence of two rare species within the Somerset Mine area. <br />1) Penstemon mensarum (Grand Mesa Penstemon) occurs within the T13S R90W <br />section 2. The CNHP considers this plant to be very rare meaning there are less <br />than 20 populations or occurrences globally. All of these occurrences are within <br />Colorado. This species is a candidate for federal endangered species listing status. <br />Per our conversation today, this population will likely not be impacted by the <br />activities currently proposed. However, it is important that this population be <br />flagged for consideration of additional, future actions. Since the population has not <br />been verified since 1977, it is recommended that the extent and vigor of the <br />population be documented in the near future. [f CNHP can be of assistance with this <br />survey, please contact us. <br />A Consen~ation Data Center For Colorado <br />a, u. Ld r,,,, <br />
