“…Species with territory sizes that exceeded the size of the largest group selection opening (0.65 ha) were the eastern bluebird (Sialia sialis), indigo bunting, alder¯ycatcher, and olive-sided¯ycatcher (Contopus borealis). Bluebirds were absent from group selection openings, and although uncommon in this study, are known to breed in clearcut openings (Conner and Adkisson, 1975;Crawford et al, 1981). Alder ycatchers and olive-sided¯ycatchers were observed exclusively in clearcuts, although low numbers of observations prohibited any de®nitive conclusion of size requirements.…”

Clearcutting creates habitat for many species of early successional songbirds; however, little information is available on bird use of small forest openings created by group selection harvests. Group selection harvests are increasing on the White Mountain National Forest due to negative public response to clearcutting. The objective of this study was to determine if avian species richness and composition differ between clearcut and group selection openings, and between mature stands and the uncut portions of group selection stands. Point count surveys were conducted during the 1992 and 1993 breeding seasons within six study blocks in the White Mountain National Forest, NH. Each block consisted of a clearcut stand, a group selection stand and a mature stand. Species richness per stand was signi®cantly higher in clearcut openings (p 0.010) than in group selection openings. Forested areas surrounding group selection openings were similar to mature stands in species richness (p 0.848) and composition. Our data suggest that, relative to avian use, the group selection system does not provide habitat similar to that created by clearcutting in extensive northern hardwood stands. The group selection system appears to retain much of the mature forest bird community while providing for a limited number of early successional bird species. Gradual replacement of clearcutting with group selection harvests could result in reduced avian diversity across large forested tracts. #

“…Habitat alteration due to forest management can influence several life-history aspects (demography, behaviour, habitat use, reproductive activity, abundance, etc.) of forest-dwelling vertebrates (Crawford et al 1981;Mahan & Yahner 1996;Taulman et al 1998;Humes et al 1999;Grialou et al 2000;Castleberry et al 2002).…”

Nest site preference of common dormouse was studied in two different habitat types of central Italy: a mesophilous deciduous forest dominated by Fagus sylvatica, and a thermophilous deciduous oak wood with Quercus cerris and Q. pubescens. In each site, 50 nest boxes were fixed to trees and monitored monthly for two years (May 1998-April 2000. Moreover, in both study sites, 19 habitat variables were measured within a 3-m radius circular plots centred on each nest box. We hypothesised that specific habitat features may induce common dormice to choose a particular site for nesting. Therefore, we compared habitat variables, recorded at the neighbourhood of either occupied or unoccupied nest boxes, in order to identify the importance of factors in nest site preference. In both beech and oak woodlands, the choice of nest site was affected by understorey vegetation structure rather than species diversity. In particular, the common dormouse prefers sites with high understorey density probably for the presence of route-ways through branches and visual protection from predators.

“…But serious problems can arise from this reductionism, and the idea that a single species can be selected as an indicator of the responses of all members of its guild to environmental changes should probably be rejected (Verner 1984). The choice of management-indicator species has not usually been made from a cautious, preservationist perspective, and old-growth species have fared poorly under this approach (Crawford andothers 1981, Graul andMiller 1984). Perhaps the indicator species concept has served primarily as an excuse for species biology-oriented managers to continue the single-species management they know best.…”

ABSTRACT/The present focus of practical conservation efforts is limited in scope. This narrowness results in an inability to evaluate and manage phenomena that operate at large spatiotemporal scales. Whereas real ecological phenomena function in a space-time mosaic across a full hierarchy of biological entities and processes, current conservation strategies address a limited spectrum of this complexity. Conservation typically is static (time-limited), concentrates on the habitat content rather than the landscape context of protected areas, evaluates relatively homogeneous communities instead of heterogeneous landscapes, and directs attention to particular species populations and/or the aggregate statistic of species diversity. Insufficient attention has been given to broad ecological patterns and processes and to the conservation of species in natural relative abundance patterns (native diversity).The authors present a conceptual scheme that evaluates not only habitat content within protected areas, but also the landscape context in which each preserve exists. Nodes of concentrated ecological value exist in each landscape at all levels in the biological hierarchy. Integration of these highquality nodes into a functional network is possible through the establishment of a system of interconnected multiple-use modules (MUMs). The MUM network protects and buffers important ecological entities and phenomena, while encouraging movement of individuals, species, nutrients, energy, and even habitat patches across space and time. An example is presented for the southeastern USA (south Georgia-north Florida), that uses riparian and coastal corridors to interconnect existing protected areas. This scheme will facilitate reintroduction and preservation of wide-ranging species such as the Florida panther, and help reconcile species-level and ecosystem-level conservation approaches.
