“…Silver-haired bats were active in unharvested patches on only one occasion in Alberta, showed intermediate levels of activity in 20% and 50% retention patches, and had their highest activity level in clearcuts (Patriquin and Barclay 2003). In West Virginia, silver-haired bats were more active in both clearcuts and deferment cuts (6-10 m 2 /ha residual basal area) than in intact stands and stands cut to a 40-cm diameter limit; this pattern was opposite to that shown by little brown and northern longeared bats (Owen et al 2003(Owen et al , 2004.…”

In the boreal forest region, partial-harvest silviculture has been garnering increasing interest as a means of maintaining wildlife species and habitat structure associated with late-successional forests. If late-successional species can find suitable habitat in partially harvested stands with a given level of structural retention, then partial harvesting might represent a viable silvicultural tool for maintaining wildlife dependent on mature or old-forest habitat within managed stands over time. Here we summarize literature on the responses of late-successional amphibians, birds, and mammals in Ontario's boreal region to various intensities of partial harvesting. We assess species responses from comparisons of habitat use in harvested and unharvested stands; we do not explicitly consider impacts of partial harvesting applied over large areas across the landscape. At the stand scale, light-intensity harvesting (70% retention) negatively affects several passerine birds, as well as spruce grouse winter habitat, but most late-successional species (including all mammals and amphibians considered) appear to be tolerant of this level of habitat alteration. Moderate-intensity harvesting (50% retention) was found to reduce the abundance of about 40% of the species considered, particularly cavity-and snag-dependent species (martens, northern flying squirrels, owls) and passerine birds that forage or nest in the canopy and understory. Highintensity (30% retention) partial harvesting was found to provide unsuitable habitat for about one quarter of all late-successional species, including most forest raptors, pileated and black-backed woodpeckers, brown creepers, northern flying squirrels, and woodland caribou. Also, studies indicate that additional passerine bird species would decrease in abundance, as would small, moisture-dependent, terrestrial species such as short-tailed shrews, red-backed voles, and eastern red-backed salamanders. There is a need to strengthen our understanding of responses to partial harvesting for nonpasserine birds and large mammals, and to verify species responses through experimental studies within Ontario's boreal region.Key words: structural retention, selection, shelterwood, seed tree, cavities, snags, downed woody debris, habitat suitability, amphibians, birds, mammals, biodiversity, review RÉSUMÉ Dans la région de la forêt boréale, la sylviculture basée sur une récolte partielle a attiré de plus en plus d'attention en tant que moyen de préserver les espèces sauvages et la structure du milieu associé aux forêts de fin de succession. Si les espèces de fin de succession peuvent retrouver un milieu adéquat dans les peuplements ayant subi une coupe partielle qui préserve à un niveau donné la structure du milieu, alors la coupe partielle pourrait constituer un outil sylvicole viable pour la préservation de la faune dépendante d'une forêt mûre ou d'une vieille forêt retrouvée au cours du temps parmi les peuplements aménagés.

“…Northern long-eared bats glean insects from foliage but rarely forage over water (Owen et al, 2003), and therefore have no requirement to roost close to water bodies other than possibly to drink. While little brown bats regularly forage often over water (Anthony and Kunz, 1977), they also frequently forage within the forests (Krusic et al, 1996;Jung et al, 1999).…”

“…Therefore, we calculated the percentage of each land cover type in a 2-km buffer surrounding each park (Ghert and Chelsvig 2003). All extant bat species in the region are known to forage up to 2 km or more from their roost sites (Menzel et al 2001;Owen et al 2003;Elmore et al 2005;Broders et al 2006). We consolidated the original 19 land cover types in the NLCD into six land cover types: water, developed (low and high intensity residential, commercial, industrial, and transportation), barren (emergent rock, sand, quarries, and mines), forested, open (pastures, row crops, and urban grasses), and wetlands (woody and emergent herbaceous wetlands).…”

“…Eastern pipistrelles (Pipistrellus subflavus) should be detected similarly between forested and fragmented parks, and more frequently at rural parks, which were closer to hibernacula (Menzel et al 2002a, Ghert and Chelsvig 2004. We expected that northern myotis (Myotis septentrionalis) and eastern small-footed myotis (Myotis leibii), a Maryland state-endangered species, would be encountered more frequently in rural, forested parks (Caceres and Barclay 2000;Owen et al 2003;Patriquin and Barclay 2003;Ghert and Chelsvig 2004;Ford et al 2005;Wund 2006). Although Indiana myotis, a federally-listed endangered species, also most likely would be detected in forested parks (Clawson 2002;Ford et al 2005), they could occur throughout the landscape regardless of distance to hibernacula because of their ability to migrate >500 km (Kurta and Murray 2002).…”

We examined the relationship between bat species activity and composition and the extent of forest cover and urbanization in and adjacent to 11 U.S. using mist nets, harp traps, acoustical detectors, and visual observations in a variety of habitats. Our efforts included 363 trap nights across 74 sites along with acoustical sampling at 362 sites. We captured 383 bats and identified 6,380 echolocation passes of 6 species. Both overall and species-specific activities were affected more by forest fragmentation within parks than by urbanization adjacent to parks. With an ability to exploit anthropogenic structures for day-roosts, big brown bats (Eptesicus fuscus) were the most ubiquitous and probably the most abundant species in NCR Parks, particularly in forested, urban parks. Northern myotis (Myotis septentrionalis), and to a lesser extent, little brown myotis (Myotis lucifugus) were more prevalent in forested, rural parks of the Ridge and Valley and Blue Ridge than in eastern, less forested urban parks of the Piedmont and Coastal Plain physiographic provinces. Retention of larger, residual forest tracts and dayroosting habitat (i.e., trees and snags) would be beneficial to most species, as urban expansion continues throughout the region.
