 Along much of Yosemite 's western boundary , habitats are dominated by mixed coniferous forests of ponderosa pine , sugar pine , incense cedar , white fir , Douglas fir , and a few stands of giant sequoia , interspersed by areas of black oak and canyon live oak . A relatively high diversity of wildlife species is supported by these habitats , because of relatively mild , lower @-@ elevation climate and the mixture of habitat types and plant species . Wildlife species typically found in these habitats include black bear , coyote , raccoon , mountain kingsnake , Gilbert 's skink , white @-@ headed woodpecker , bobcat , river otter , gray fox , red fox , brown creeper , two species of skunk , cougar , spotted owl , and a wide variety of bat species .
