Loss and fragmentation of forest habitat are accompanied by an increase in the ratio of forest edge to interior forest, and the response of bats to this can vary among species. Litter from any living organ and the mortality of whole trees transfer carbon and N into the soil, where the litter and humus decay, releasing N for tree growth. For Ecol Manage 238:156–166, Perry RW, Thill RE, Leslie DM Jr (2008) Scale-dependent effects of landscape structure and composition on diurnal roost selection by forest bats. Jarrah forest in Western Australia offers one example of providing pools of mature trees using zoning. In: Lacki MJ, Hayes JP, Kurta A (eds) Bats in forests: conservation and management. Under climate change, the corresponding increase was up to 27 per cent for a 60-year rotation, compared to baseline management (Figure 4). (2007) found that barbastelle bat, B. barbastellus, emerged later from tree roosts in more open forests, probably as a result of increased predation risks, and suggested that it was important to ensure canopy heterogeneity to provide a range of roosting conditions. Unfortunately, data on densities of occupied roosts and, thus, potential for landscape-scale population estimates of bats are few (Clement and Castleberry 2013; Fleming et al. For Ecol Manage 79:13–28. Working Paper 23/1996, pp 228–237, Hayes JP, Loeb SC (2007) The influences of forest management on bats in North America. 2013). In this sense, such modelling can provide valuable support for defining optimal forest management strategies for practical forestry under changing climatic conditions. However, closed-space bat species that glean insects from vegetation and manoeuvre well within clutter benefit from a relatively dense understorey and higher tree densities, which can act as sources of insect prey (Fuentes-Montemayor et al. The first sawmill was established by Swedish settlers in Philadelphia in 1662. Nilsson and Fahlvik, 2006; Bergh et al., 2008; Jacobson and Pettersson, 2010; Hedwall et al., 2014). Use of trails as linear edges in regenerating forest has also been reported in North America (Menzel et al. We look to highlight both commonalities and differences in the various approaches to the issue in different regions. The specialist golden-tipped bat, Kerivoula papuensis, preferentially roosts in the suspended nests of small birds within riparian rainforest and such areas are excluded from harvesting (Schulz 2000; Law and Chidel 2004). However, timber yields were, on average, 3–4 per cent lower under climate change. In our study, compared to the baseline regime, the timber yield increased with fertilization of 150 kg N ha−1 once or twice during a rotation of 60 years (no breeding gain assumed) by up to 25 m3 ha−1 in Norway spruce stands, and up to 11 m3 ha−1 in Scots pine stands (see Appendices 2 and 3). Compared to the baseline management regime, the use of improved seedlings, alone or together with N fertilization, increased timber production by up to 26–28 per cent and the NPV by up to 32–60 per cent over rotation lengths of 60–70 years, regardless of tree species (although more in spruce) or climate applied. Clearcuts aim to mimic broadly the massive stand replacement events created by wildfires, which are an irregular feature of tall eucalypt forests in Australia. The Johns Hopkins University Press, Baltimore, pp 237–261, Duerr DA, Mistretta PA (2013) Invasive pests—insects and diseases. 2000; Cryan et al. On the other hand, the mean diameter of trees in a stand at the time of final felling was in different simulations in our study in the range of recommended mean diameter in practical forestry in Finland. 2009). 2009b), and eastern red bats, L. borealis, roosting in the vicinity of gated roads (O’Keefe et al. Russo D, Cistrone L, Jones G (2005b) Spatial and temporal patterns of roost use by tree-dwelling barbastelle bats, Russo D, Cistrone L, Jones G (2007) Emergence time in forest bats: the influence of canopy closure. Immediately after harvest, closed-space bats are expected to decline, but we predict subsequent recovery if the retention of roost trees is catered for. Unfortunately, the size and shape of clearcuts studied are rarely reported so an evaluation of the effects of cut size and shape on bat activity cannot be made.
