Species Habitat Present In the Silverton Landscape? Yuma myotis (BLM) No – too high elevation, not known to occur in San Juan Co. Insects (1) Great Basin silverspot (FS) No – too high elevation, not known to occur in San Juan Co. Reptiles (2) Desert spiny lizard (BLM) No – no sparsely vegetated rocky areas near flowing streams, not known to occur in San Juan County Longnose leopard lizard (BLM) No – Landscape too high elevation, not known to occur in San Juan Co. Table C-3. Forest Plan MIS species for the SJNF Species or Habitat Impacted by Action Project Impact Alternatives? Determination No Selecting Alternative 2 or 3 will have “no impact” on Yuma myotis. No further discussion is required No Selecting Alternative 2 or 3 will have “no impact” on Great Basin silverspot. No further discussion is required No Selecting Alternative 2 or 3 will have “no impact” on desert spiny lizard. No further discussion is required No Selecting Alternative 2 or 3 will have “no impact” on longnose leopard lizard. No further discussion is required MIS Species Preferred Habitat Brought Forward for Detailed Analysis? Birds (9) Columbian sharp-tailed grouse (Tympanuchus phasianellus columbianus) Reintroduced to non-federal lands near Dolores by Colorado Division of Wildlife in 2004. Currently not on Columbine or Pagosa RD but Dolores RD may retain habitat. No, grouse was not analyzed further as SJNF MIS because it has not been documented to occur on the SJNF for decades and no habitat is present in the Silverton Landscape. Green-tailed towhee (Pipilo chlorurus) Gambel oak/mountain shrub, pinyonjuniper, sagebrush, and riparian. Spring-fall resident. Yes, towhee habitat is present in the Landscape and potentially affected by sheep grazing. Hairy woodpecker (Picoides villosus) All forested habitats, associated with snags for foraging and nesting. Yearround resident. No, woodpecker habitat is present in the Landscape but nesting and foraging habitat will not be affected by sheep grazing. No further analysis is necessary. Mallard (Anas platyrhynchos) Aquatic and riparian. Spring-fall resident and winter migrant. No, mallard habitat is present in the Landscape but nesting and foraging habitat will not be affected by sheep grazing. No further analysis is necessary. No, turkey was not analyzed further as SJNF MIS. Merriam’s turkey (Meleagris gallopavo merriami) Grass-forb meadows, ponderosa pine/Gambel oak and open montane forests, aspen. Year-round resident. Turkey habitat is present in the landscape but nesting and foraging habitat will not be directly affected by sheep grazing. No further analysis is necessary. Mexican spotted owl (Strix occidentalis lucida) Mixed conifer habitat (Douglas-fir, ponderosa pine, white fir) located in steep rock-walled canyons. Only one confirmed occurrence on the SJNF, in late summer. Early-successional, alpine, mature No, spotted owl was not analyzed further as SJNF MIS. Spotted owl has not been confirmed to breed on the SJNF and no suitable habitat is present in the Landscape. No further analysis is necessary. Mountain bluebird (Sialia currucoides) aspen, mixed conifer, Gambel oak/mountain shrub, pinyon-juniper, ponderosa pine, and sagebrush, snag and cavity-dependant. Spring-fall resident. Yes, bluebird habitat is present in the Landscape and foraging habitat is potentially affected by sheep grazing. Northern goshawk (Accipiter gentilis) Mature deciduous, coniferous and mixed forests. Spring-fall resident and winter migrant. No, goshawk was not analyzed further as SJNF MIS. Goshawk habitat is present in the Landscape but nesting and foraging habitat will not be affected by sheep grazing. No further analysis is necessary. 115
MIS Species Preferred Habitat Brought Forward for Detailed Analysis? Southwestern willow flycatcher (Empidonax traillii extimus) Fish (4) Brook trout (Salvelinus fontinalis) Aquatic. Resident Brown trout (Salmo trutta) Aquatic. Resident. Colorado River cutthroat trout (Oncorhynchus clarki pleuriticus) Rainbow trout (Oncorhynchus mykiss) Insects (1) Uncompahgre fritillary butterfly (Boloria acrocnema) Endangered Mammals (10) Willow riparian with patch size 30 ft. x 30 ft. x 5 ft. tall, up to ¼ acre or larger. Summer resident, only one regular breeding location on the SJNF. Aquatic. Resident. Aquatic. Resident. Snow willow located in alpine habitat. Abert’s squirrel (Sciurus aberti) Ponderosa pine. Year-round resident. American marten (Martes americana) Spruce-fir and cool-moist mixed conifer. Year-round resident. Beaver (Castor canadensis) Riparian/wetlands. Year-round resident. Black bear (Ursus americanus) All forested habitats. Resident. Canada lynx (Lynx canadensis) Deer mouse (Peromyscus maniculatus) Elk (Cervus elaphus) Mule deer (Odocoileus hemionus) Spruce-fir, cool-moist mixed conifer, high elevation aspen mixed with sprucefir or cool-moist mixed conifer, and willow riparian adjacent to the above habitats. Reintroduced to SJNF by CDOW. All forested and non-forested habitats. Resident. All terrestrial habitats; pine, pinyonjuniper and mountain shrublands in winter. Resident. All terrestrial habitats; pine, pinyonjuniper, and Gambel oak/mountain shrublands in winter. Resident. River otter(Lontra canadensis) Watercourses with fish. Resident. No, not analyzed further as SJNF MIS. Flycatcher habitat is present in the Landscape but sheep do not regularly occur in the one habitat patch that is suitable for flycatchers and livestock do not appear to have any impact on its habitat structure. No further analysis is necessary. No, brook trout is not analyzed further as SJNF MIS. Trout habitat is present in the Landscape but will not be directly affected by sheep grazing. No further analysis is necessary. No, brown trout is not analyzed further as SJNF MIS. Trout habitat is present in the Landscape but will not be directly affected by sheep grazing. No further analysis is necessary. No, there are no conservation populations in the Landscape. No, rainbow trout is not analyzed further as SJNF MIS. Trout habitat is present in the Landscape but will not be directly affected by sheep grazing. No further analysis is necessary. No, UFB was not analyzed further as SJNF MIS. Butterfly habitat is present in the Landscape but project design criteria will prevent livestock grazing impacts. No further analysis is necessary. No, Abert’s squirrel was not analyzed further as SJNF MIS. Squirrel habitat is present in the Landscape but will not be affected by sheep grazing. No further analysis is necessary. No, marten was not analyzed further as SJNF MIS. Marten habitat is present in the Landscape but will not be affected by sheep grazing. No further analysis is necessary. No, beaver was not analyzed further as SJNF MIS. Beaver habitat is present in the Landscape but will not be directly affected by sheep grazing. No further analysis is necessary. No, bear was not analyzed further as SJNF MIS. Bear habitat is present in the Landscape but will not be affected by sheep grazing. No further analysis is necessary. Yes, lynx habitat is present in the Landscape and primary prey is potentially affected by livestock grazing. No, mouse habitat is present in the Landscape but their abundance and distribution is driven by climatic conditions, not sheep grazing. Yes, elk habitat is present in the Landscape and food sources are potentially affected by sheep grazing. Yes, deer habitat is present in the Landscape and food sources are potentially affected by sheep grazing. No, otter was not analyzed further as SJNF MIS. Otter habitat is present in the Landscape but will not be directly affected by sheep grazing. No further analysis is necessary. 116
