Detailed information about three-dimensional vegetation structure proves increasingly useful for 25 studying species-habitat relationships in forest ecosystems. This particularly applies to species that 26 make extensive use of the three-dimensional habitat space in forests, such as bats. Bats show 27 considerable variation in flight morphology and echolocation traits that are shaped by habitat features, 28 and are excellent model taxa for investigating relationships between vegetation structure and animal 29 occurrence and movement. The aims of this study were (1) to investigate the relationship between the 30 activity of bats and forest structure and (2) to compare the performance of airborne Light Detection 31 and Ranging (LiDAR) and terrestrial field surveys for measuring habitat features in a representative 32 sample of mixed and deciduous forests in the Swiss lowlands. Leaf-on and leaf-off LiDAR data were 33 used separately, as well as in combination, to evaluate the relative strength of these datasets to 34 describe 3D canopy architecture and vertical forest structure. Field measurements included structural 35 variables such as leaf area index (LAI), vertical layering, snags, as well as shrub and ground 36 vegetation cover. We recorded 145,433 echolocation call sequences from bats and assigned them into 37 three echolocation guilds (short-, mid-and long-range echolocators; SRE, MRE, LRE, respectively) 38 treating separately the dominant species (Pipistrellus pipistrellus; Pp). We used Generalized Mixed 39Effects Models (GLMMs) and applied an information-theoretic approach to assess relationships 40 between guild-specific activity patterns of bats and forest structure in the forest interior, as well as in 41 forest gaps. Standardized coefficients were used to evaluate variable effect sizes and relative 42 importance. We found that guild-specific bat activity was clearly related to three-dimensional forest 43 structure. The activity of SRE, MRE and Pp bats was negatively affected by foliage height diversity, 44indicating that a large scatter of vegetation elements along 3D forest profiles may restrict accessibility 45 for manoeuvrable bats. Outer canopy surface ruggedness was significantly and positively related to 46 the activity of MRE and LRE bats, as well as Pp, all of which may profit from increased...

“…Studies of bat activity at stand and landscape scales in both north-western and north-eastern forests of North America demonstrated that patterns in habitat use of bats were largely determined by habitat characteristics at the local or stand level and not at landscape scales (Erickson and West 2003;Ford et al 2006), suggesting that silvicultural systems that create a mosaic of treatments across forested landscapes with local differences in habitat structure will support a higher overall diversity of bat species (Wigley et al 2007). This approach has been recommended in published studies (Loeb and Waldrop 2008;; however, other sources report both stand and landscape metrics in North America and Europe to be important in selection of activity areas of bats (Loeb and O'Keefe 2006;Yates and Muzika 2006;FuentesMontemayor et al 2013), with tri-coloured bats, P. subflavus, and eastern red bats, L. borealis, most affected by local stand structure, northern long-eared bats, M. septentrionalis, negatively affected by forest edge, and Indiana bats, M. sodalis, positively affected by dead tree density and non-forested land cover. Other studies corroborate that selection of roosting sites in both bark-and cavity-roosting and foliage-roosting bat species is strongly influenced by landscape-scale metrics in both eastern and western forests of North America (Limpert et al 2007;Arnett and Hayes 2009;Lacki et al 2010).…”

Forests are one of the most important habitats for insectivorous bats as they offer the potential for both roosting and foraging. We reviewed silvicultural literature from North America, Australia, and Europe and found that diverse research approaches have revealed commonalities in bat responses to forest silviculture. Almost all silvicultural treatments evaluated were compatible with some use by forest bats, though different bat ensembles respond in different ways. Ensemble ecomorphology was a consistent predictor of how bats respond to vegetative clutter and its dynamic changes as forests regenerate and develop a dense structure following harvesting. Sustaining high levels of bat diversity in timber production forests requires a mix of silvicultural treatments and exclusion areas staggered across the landscape, regardless of forest type or geographic region. Use of edge habitats, exclusion areas/set-asides, and riparian corridors for roosting and foraging by bats were consistent themes in the literature reviewed, and these habitat elements need to be considered in forest planning. Densities of hollow or dead trees sufficient to support large populations of roosting bats are unknown and remain a major knowledge gap, but will likely be species contingent. New paradigm shifts in forest management away from the use of even-aged systems to multi-spatial scale retention of mature forest including trees with cavities should be beneficial to bats, which are influenced by landscape-scale management.

“…For all species, we included distance to stream, and distance to agriculture, as these variables have been found to be important for bats in general (Yates and Muzika, 2006;Either and Fahrig, 2011;Grindal et al, 1999) and particularly those in urban/agricultural matrices (Gehrt and Chelsvig, 2004;Duchamp and Swihart, 2008). We retained all measures of forest for example upland, swamp and floodplain) and open cover (for example meadow and prairie), as well as savanna because of its unique status in this region…”

Protected areas may function as islands of habitat in otherwise adverse environments for many species of North American animals. It is currently unclear how to maintain suitable foraging habitat for bats within these areas. Bats are nocturnal and highly mobile, making their specific needs difficult to determine. Using data collected from acoustically surveyed sites within protected areas in the Oak Openings Region of Northwest Ohio, a biodiversity hotspot, we developed spatially explicit macrohabitat models using maximum entropy modeling (Maxent). We then used data collected by citizen scientists to test these models to determine their success in predicting species presence. We found that the models were successful (AUC values > 0.75) at predicting the occurrence of the seven species for which models were developed, Lasionycteris noctivagans, Lasiurus borealis, Lasiuruscinereus, Myotis lucifugus, Myotiss eptentrionalis, Nycticeius humeralis, and Perimyotis subflavus. Within protected areas, it is important to manage for heterogeneous habitat composition at this intermediate scale to maintain potential for foraging areas for all occurring bat species. Data collected by citizen scientists is useful to test spatially explicit models and can potentially be used to monitor long term changes in bat species composition in these systems and across regions.
