During 2001, we used active acoustical sampling (Anabat II) to survey foraging habitat relationships of bats on the Savannah River
Site (SRS) in the upper Coastal Plain of South Carolina. Using an a priori information-theoretic approach, we conducted logistic
regression analysis to examine presence of individual bat species relative to a suite of microhabitat, stand, and landscape-level
features such as forest structural metrics, forest type, proximity to riparian zones and Carolina bay wetlands, insect abundance, and
weather. There was considerable empirical support to suggest that the majority of the activity of bats across most of the 6 species
occurred at smaller, stand-level habitat scales that combine measures of habitat clutter (e.g., declining forest canopy cover and
basal area), proximity to riparian zones, and insect abundance. Accordingly, we hypothesized that most foraging habitat
relationships were more local than landscape across this relatively large area for generalist species of bats. The southeastern
myotis (Myotis austroriparius) was the partial exception, as its presence was linked to proximity of Carolina bays (best-
approximating model) and bottomland hardwood communities (other models with empirical support). Efforts at SRS to promote
open longleaf pine (Pinus palustris) and loblolly pine (P. taeda) savanna conditions and to actively restore degraded Carolina bay
wetlands will be beneficial to bats. Accordingly, our results should provide managers better insight for crafting guidelines for bat
habitat conservation that could be linked to widely accepted land management and environmental restoration practices for the
region. (JOURNAL OF WILDLIFE MANAGEMENT 70(5):1200-1209; 2006)

In forested landscapes, distributional patterns of bats are
influenced by a complex interplay of habitat factors from the
individual tree and stand-level to the landscape level, as well
as prey resources, temporal factors, climate, and the
autoecology of individual species of bats. Common to all
points on the landscape and across all habitat scales,
presence of bats at a single location at any moment can
depend upon time, temperature, humidity, precipitation,
barometric pressure, wind speed, ambient light intensity,
and abundance and availability of insects (Barclay 1985,
Clem 1993, Hayes 1997, Broders et al. 2003). At smaller
habitat scales (e.g., forest canopy gap to forest stand or
patch), activity can be related to proximity of riparian
habitat, forest structural characteristics, echolocation char-
acteristics, wing morphology, and prey preference of bat
species (Aldridge and Rautenbach 1987, Jung et al. 1999,
Menzel et al. 2005b). At larger landscape scales, bat presence
is often related to overall abundance of day roosts; proximity
of foraging habitat to day-roost sites; quality, density, and
spatial juxtaposition of all available foraging habitats; and
frequency and cumulative nature of disturbances on the
landscape (Best and Hudson 1996, Crampton and Barclay
1997, Evelyn et al. 2004).
Recent efforts that have attempted to elucidate these
processes, and their single and synergistic ecological agents
operating across spatial and temporal scales, have shown

strong linkages between activity of bats and a combination
of microhabitat and landscape variables (Gehrt and Chelsvig
2003, 2004). Other research suggests that bat activity is a
function of the features of smaller forest patch (Erickson
and West 2003, Ford et al. 2005) or specialized landscape
components (Grindal et al. 1999, Seidman and Zabel 2001,
Johnson et al. 2003, Menzel et al. 2005b). Unlike day-roost
data, the difficulty of collecting adequate activity data from
radiotelemetry over numerous areas or among multispecies
communities and the imprecise ability to link acoustical data
with individual bats has impeded our understanding of bat
activity patterns and habitat associations (Russ and Mont-
gomery 2002, Broders 2003).
Within the Southern Pine Region (SPR) of the Coastal
Plain of the southeastern United States, bat communities are
considered to be of high conservation value (Menzel et al.
2003). This portion of North America is undergoing
unprecedented landscape change caused by rapid growth
of the human population and associated urban and exurban
sprawl (Wear and Greis 2002). More importantly, this rapid
pace of forest habitat alteration is projected to continue for
the foreseeable future (Alig and Butler 2004). Forest
conversion or alteration associated with urban sprawl is
further complicated because composition of many extant
forests is expected to continue shifting to more intensively
managed plantation systems at least through the first 3
decades of the 21st Century (Wear and Greis 2002).
However, with no threatened or endangered species such as
