as ancillary information. Not considered in this analyses were other established ranking systems, i.e. <br />the IUCN Red List, Bureau of Land Management's and U.S. Forest Service's lists of sensitive <br />species. <br />Because of the inherent difficulty in comprehensively locating, surveying, and mapping plant <br />populations, the evaluation was somewhat flexible regarding the presence/absence of documented <br />species occurrence within Gunnison County. That is, if a species is known to occur within regional <br />proximity (i.e. in surrounding counties), then the determination was slightly weighted towards the <br />possibility that it may also occur in Gunnison County even if it has yet to be officially identified and <br />documented in the County. <br />A likelihood of presence determination ranking system was developed for this study ranging from <br />"Some likelihood" to "No likelihood". Each species was designated a likelihood of onsite occurrence <br />and justification for the determination was explained. The ranking system developed for this study <br />are qualitative and intended for purely informational purposes based on best scientific judgment. The <br />"likelihood" definitions for the ranking system are as follows: <br />Some Likelihood: The project site is within the species' range and onsite habitat, substrate, and <br />elevation is suitable for the species. The species is thought to be more common and/or occurs in a <br />wider range of habitats. <br />Unlikely: Little possibility that a population previously undocumented in Gunnison County may <br />occur in the project site. Known populations occur in nearby Counties and the habitat/substrate <br />and elevation are substantially appropriate for the species. However, due to species rarity, it <br />remains very unlikely that the species would occur within the project site. <br />Very Unlikely: Either known species populations are not within close regional proximity (i.e. <br />adjacent or nearby Counties), or the habitat/substrate and/or elevation is largely inappropriate for <br />the species. <br />No Likelihood: The appropriate habitat and/or substrate and elevation does not exist on the <br />project site and known occurrences of the species are not within or adjacent to Gunnison County. <br />It is unreasonable to assume any likelihood for species occurrence onsite. <br />30 <br />PAMpls\06 CO\26\06261003 MCC Refuse Pile Site Review & Permit\WorkFiles\Permit Application\2014 Revision\Exhibit 82 2014-05- <br />29.docx <br />
