Data in Table 2 were calculated before the establishment of new protected areas (South Okanagan Grasslands, White Lake Grasslands) as part of the Provincial Protected Areas Strategy. Quantitative data on land tenure for Spotted Bat habitat exists only for the southern Okanagan and Similkameen valleys (Ministry of Environment, Lands and Parks 1998). They roost on vertical cliffs and in open canyons. Diet. The spotted bat occupies a range of habitats in Washington from shrub-steppe and forests (e.g., ponderosa pine, Douglas-fir) to cliffs and water sources (e.g., marshes, open water, riparian areas) from 300 to 850 m in elevation. The habitat suitability map (Figure 6) demonstrates that roosting habitat in this region is fragmented and patchily distributed, a pattern consistent with the distribution of known roost sites described by Sarell and Haney (2000). According to Redpath (1990) more than 90% of the land in the southern Okanagan-Similkameen has been altered from its 'normal' state. These bats have black fur with white spots and a white belly, large (four centimetres long) pink ears and a wingspan of about 30 centimetres.

Black fur on back, with two large white spots on shoulders, large white spot on rump, white fur below. Vaseux Lake and McIntyre Bluff in the southern Okanagan Valley. 1992). The habitats of the spotted bat are undisturbed roosts on cliffs along the Grand Canyon in Arizona, and open and dense deciduous and coniferous forests, hay fields, deserts, marshes, riparian areas, and dry shrub-steppe grasslands in Arizona, California, Colorado, Oregon, New Mexico, Utah, and British Columbia, Canada. In the Chilcotin River valley at the northern edge of the range, Spotted Bats forage in riparian habitats and open upland habitats with Douglas-fir. Their habitat always seems to be associated with a water source such as a spring, creek, river or lake. A spotted bat ESA listing could result in the closure of climbing routes where roosts are found, and could impact livestock water and grazing management in areas with suitable foraging habitat. Located in NE Oregon, the Blue Mountains ecoregion is the largest ecoregion in the state. Occurrence of the spotted bat in Utah: Journal of Mammalogy: Journal: Utah: Euderma maculatum 379: Finley, R.

Be-ing secretive and nocturnal, it has few natural enemies. Spotted Bats are one of the rarest and hardest to catch bats in the USA. Early research suggested that this bat favored ponderosa pine forests, but more recent investigations show that the species uses areas tied closely to cliffs and water. This sound was recorded at Yosemite National Park in California. Improve understanding of basic ecology and habitat associations. For example, according to the Habitat atlas for wildlife at risk-south Okanagan and lower Similkameen (British Columbia Ministry of Environment, Lands and Parks 1998) about 85% of the valley bottom riparian habitat has disappeared. Experience More. Credit / Author: NPS. Species that may benefit from efforts to protect Spotted Bat roosting habitat include other cliff-roosting bat species (Pallid Bat New discoveries regarding its range, ecology, population dynamics, and life history will be made in the future.

It is largely a high elevation desert-like area dominated by sagebrush communities and habitats. for the rare Spotted Bat. In fact they stayed on the list even after I saw them […] ISSUES The primary issue facing this species is the lack of knowledge on abundance, 1999) that have shown no evidence for roosting in caves or mines. This ecoregion varies dramatically from its cool, moist border with the West Cascades ecoregion to its dry eastern border, where it meets sagebrush desert landscapes. Like other bats, this species … Bureau of Land Management, U.S. Department of the Interior, and Denver Service Center, Denver, CO. Storz, J. F. 1995. Of six habitats studied by Leonard and Fenton (1983) in the southern Okanagan Valley, foraging was observed in old fields and hay fields bordering ponderosa pine forest. Assess distribution, abundance, and trends. Hardy (1941) reported four Spotted Bats hibernating in a cave in Utah, but his anecdotal observation is inconsistent with several comprehensive surveys of mines and caves in various parts of the range (e.g. Spotted Bat lives in desert scrub and open forest areas. A habitat model developed for the southern Okanagan and Similkameen valleys (Ministry of Environment, Lands and Parks 1998; Sarell and Haney 2000) was based on the presence of steep cliffs with horizontal or vertical crevices for roosting habitat. Habitat. The bat prefers habitats along waterways, where there are nearby cliffs or steep hillsides. (1995) concluded that there has been a "severe" reduction in foraging habitat citing "urbanization, destruction of wetlands, extensive irrigation, and the development of orchards, crop lands, and pasture". Spotted Bat . These new protected areas support additional Spotted Bat habitat and probably increase the proportion of habitat in conservation land to about 10%. Wai-Ping and Fenton (1987) found considerable variation in the height, length, and aspect of six cliffs used as day roosts in the southern Okanagan valley. It is dominated by a rolling landscape of arid lowlands dissected by several important rivers, and extends from the eastern slopes of the Cascades Mountains, south and east from the Columbia River to the Blue Mountains. 1965. Like all bat species in Canada, the diet of spotted bat consists of flying insects, such as moths, flies and beetles. Maintain open-water sources in desert landscapes. The Spotted Bat is very special-ized in terms of its food habits and habitat needs. The impacts of agricultural development and urbanization on Spotted Bat roosting habitat are minimal. In this article, both monikers will be used to describe this interesting bat species. The spotted bat is a black bat with very large, pink ears. Subtle habitat disturbances in a few places could extirpate a large fraction of the known population. Spotted Bat.
