The slides presented here in brief for B. Sc. Changes in total bat activity over 14 years in an alternate-coupe logging system in southern Australia (B. Silviculture involves a diverse range of techniques to manipulate growth conditions, extract resources, and facilitate regeneration within forests. The potential diameter growth is also affected by the diameter of the tree, the atmospheric carbon dioxide (CO2) concentration, and by the genotype (e.g. Northern J Appl Forest 21:154–159, Park KJ, Masters E, Altringham JD (1998) Social structure of three sympatric bat species (Vespertilionidae). Available at: Ford WM, Menzel MA, Rodrigue JL et al (2005) Relating bat species presence to simple habitat measures in a central Appalachian forest. Surprisingly, bat activity was low at the retained aggregates themselves, both in their centre and along the edge, and it is not known to what extent bats roost in these locations. J Appl Ecol 40:646–657, Perdue M, Steventon JD (1996) Partial cutting and bats: a pilot study. Such trees have a greater likelihood of supporting larger populations of roosting bats and persist for longer than smaller diameter dead trees (Lacki et al. Rosvall et al., 2002; Ruotsalainen, 2014; Haapanen et al., 2016; Jansson et al., 2017). R. Soc. One longitudinal study in Australian eucalypt forests, initiated in 1998, has been investigating alternate-coupe-integrated harvesting for woodchips and saw-logs, and although currently unpublished, a summary is presented here (B. Roosting on lower slopes was also found in a subtropical Australian forest, where lactating eastern forest bats, V. pumilus, roost in hollow trees in riparian zones during early summer, but shift up-slope during autumn when bats begin to mate (Law and Anderson 2000). Nilsson and Fahlvik, 2006; Bergh et al., 2008; Jacobson and Pettersson, 2010; Hedwall et al., 2014).

When existing old-growth forests are to be managed for timber production, they will obviously lose their old-growth status according to most, if not all, definitions. As mnagement objectives become more clearly defined nd desired stnd conditions are identified, silviculture will play a major role in developing practices to attain them. Mississippi Department of Wildlife, Fisheries, and Parks, Jackson, Mississippi, Mitchell RJ, Palik BJ, Hunter ML Jr (2002) Natural disturbance as a guide to silviculture. Silviculturists have had less influence on the early development of "New Forestry" thn other resource specialists. One possible reason for avoiding using ‘habitat trees’ as roosts was the relatively low density of hollow roosts (see 3.2 Deadwood availability and hollow tree density). Bats, however, were able to roost within managed forest, albeit in smaller numbers by exploiting roost sites in live trees and rock crevices.
