Abstract This section addresses existing condition to proposed, threatened, endangered or sensitive (TES) fauna (USDA-Forest Service, 2007) that have been documented or have suspected occurrences on the Valles Caldera National Preserve (VCNP). The existing condition is described for each species, group of species, or habitat. Species presence/absence determinations were based on habitat presence, wildlife surveys, recorded wildlife sightings, and non-Forest Service databases. Effects on habitats are discussed, with the assumption that if appropriate habitat is available for a species, then that species occupies or could occupy the habitat. This strategy is based upon science that demonstrates connections between species populations and viability and the quantity and condition of habitat at appropriate scales of analysis (Baydack, Campa III, & Haufler, 1999). Effects on species will be determined by assessing how alternatives affect the structure and function of vegetation relative to current and historical distributions. Some wildlife habitats require a detailed analysis and discussion to determine potential effects on a particular species. Other habitats may either not be impacted or are impacted at a level which does not influence the species or their occurrence. The level of analysis depends on the existing habitat conditions, the magnitude and intensity of the proposed actions, and the risk to the resources. The analysis focuses on Threatened, Endangered and Sensitive Species (TES), landbirds including neotropical migratory birds (NTMB), and species of interest. A threatened species is an animal or plant species listed under the Endangered Species Act that is likely to become endangered within the foreseeable future throughout all or a significant portion of its range. An endangered species is an animal or plant species listed under the Endangered Species Act that is in danger of extinction throughout all or a significant portion of its range. A sensitive species is an animal or plant species identified by the Forest Service Regional Forester for which species viability is a concern either (a) because of significant current or predicted downward trend in population numbers or density, or (b) because of significant current or predicted downward trends in habitat capability that would reduce a species existing distribution. Threatened, endangered, and sensitive species effects are summarized by TES status and species. The assessment includes species that are being considered for listing as either endangered or threatened (proposed) as well as those listed.
