“…1). Because the distance between mays was large relative to the limited movements and small home ranges of many woodland salamanders (Madison, 1969;Holomuzki, 1982;Mathis, 199 1 ;Petranka et al, 1993Petranka et al, , 1994Petranka, 1998), we considered each array to be an independent sampling unit. Individual mays consisted of four, 3 m long x 61 crn high aluminum flashing in an X (Fig.…”

We surveyed cove hardwood stands aged 15, 25, 50, and 285 years following clearcutting in the southern Appalachian Mountains of northem Georgia to assess the effects of stand age and stand habitat characteristics on salamander communities using drift-fence array and pitfall methodologies from May 1994 to April 1995. Over a 60,060 pitfall trapnight effort, we collected 3937 salamanders represented by Desmognathus aeneus, Desmognathus mtznticola, Desmognathus ocoee, Ilesmognathus quadramaculatus, Eurycea bislineata, Gyrinophilus porphyriticus, Pseudotriton ruber, Pkthodon glutinosus, Plethodon serratus, and Notophtlaalmus viridescens. Analysis of covariance with pitfall array to stream distance as the covariate showed that salamander species richness and diversity measures and numbers of Desmognathus aeneus and Desmognathus ocoee were highest in stands 285 years. Eutyeea bislineata and Plethodon glutinosus were more abundant in stands 250 years old than in stands 285 years. Within cove hardwood stands, species richness and diversity measures and relative abundances of Desmogmthus spp. and Gyrinophilus porphyriticus were negatively correlated with distance to stream. Species richness and diversity were positively correlated to mounts of emergent rock. Species richness, diversity and relative abundances of Desmognathus spp. were correlated with basal area within stands and extent of connected mesic, cove hardwood habitat and amount of cove habitat within 1 km radius among stands. Eurycea bislineata was negatively correlated with landfom index, a measure of surrounding landfom sheltering, and Plethodon glutinasus was positively correlated with elevation in cove hardwood stands. Our research indicates stand age is an important factor in explaining the abundance and community composition of salamanders in southern Appalachian cove hardwood communities. Because southern Appalachian woodland salamander communities are slow to recover and are substantially changed following disturbances such as clearcutting, populations in small, isolated cove hardwood stands might be more vulnerable to extirpation or may require longer recovery times than those in larger coves. Managers may need to assess habilat features such as cove extent and habitat connectivity to minimize impacts on these taxa by forest management activities in southern Appalachian cove hardwood communities.

“…We used night-time area-constrained (2Â15 m transects) surveys and daytime sampling of arti®cial cover objects (Heyer et al, 1994). We allowed a 30 m buffer zone around transects and arti®cial cover objects on each treatment to reduce edge effects from adjacent treatments (Petranka et al, 1994).…”

“…Previous studies have shown that salamander populations decline after clearcut timber harvesting (Ash, 1988;Pough et al, 1987;Petranka et al, 1993, Petranka et al, 1994. Clearcutting increases the surface temperature and leads to drying of the litter layer (Johnson et al, 1985) limiting salamander surface activity (Fraser, 1976;Jaeger, 1980).…”

We compared the relative abundance of terrestrial salamanders before and after application of seven regeneration treatments in a low-elevation, southern Appalachian hardwood forest in southwest Virginia. Treatments included understory removal, group selection, two shelterwoods, leave-tree, clearcut, and a control. Salamander relative abundance was signi®cantly lower after harvest on the group selection (p0.005), shelterwoods (p0.007 and p0.015), leave-tree (p0.001), and clearcut treatments (p0.001). There was no signi®cant difference in relative abundance during the same period on the control (p0.788) or understory removal (p0.862) treatments. #

“…Harper and Guynn (1999) also reported a quick recovery of the salamander population after clearcutting. Other studies, however, have noted a decline in salamander population following clearcutting for several decades (Ash 1997;Mitchell et al 1997;Pough et al 1987;Petranka et al 1994).…”

. Effects of two silvicultural practices on soil fauna abundance in a northern hardwood forest, Québec, Canada. Can. J. Soil Sci. 82: 105-113. Soil fauna play a key role in soil fertility and productivity of forest ecosystems and represent an important base of terrestrial food chains. The impact of forest management on soil fauna should be considered when sustainable forest management and conservation of biodiversity are desired. We evaluated the impact of selective cutting and strip clearcutting on soil fauna abundance in a northern hardwood forest of the Lower Laurentians of Québec. Twelve years after strip clearcutting, the abundance of carabid beetles (Coleoptera: Carabidae), collembolans (Hexapoda: Collembola) and snails (Stylommatophora: Sigmurethra) was greater in the strip clearcuts than the adjacent undisturbed strips. Snails and millipedes (Polydesmida: Polydesmidae) were more abundant in the selective cuts 6 to 8 yr after treatment. Spiders (Arachnida) were the only organism whose abundance was lower in the selective cuts than in the adjacent undisturbed forest. No significant negative effect of the silvicultural treatments was noted for the abundance of other caught organisms. This one-season sampling suggests there are few negative impacts associated with low intensity selective cutting and strip clearcutting on the abundance of soil fauna in this northern hardwood forest stands 6 to 12 yr after harvest. La faune du sol joue un rôle primordial en ce qui concerne la fertilité du sol et la productivité des écosystèmes forestiers et constitue un maillon important de la chaîne alimentaire terrestre. Les impacts des activités forestières sur les organismes du sol devraient donc être considérés dans un contexte d'aménagement forestier durable et de conservation de la biodiversité. Nous avons évalué l'impact de coupes de jardinage et de coupes totales par bandes sur l'abondance de la faune du sol dans une érablière des basses Laurentides de la région de Québec. Douze ans après la coupe totale par bandes, l'abondance des carabidés (Coleoptera: Carabidae), des collemboles (Hexapoda: Collembola) et des escargots (Stylommatophora: Sigmurethra) était plus élevée dans les bandes coupées comparativement aux bandes adjacentes non-perturbées. Les escargots et les millipèdes (Polydesmida: Polydesmidae) étaient plus abondants dans les forêts jardinées 6 à 8 ans après traitement comparativement à celles témoins. L'araignée (Arachnida) représentait le seul organisme dont l'abondance était plus faible dans les forêts jardinées comparées aux secteurs témoins. Aucun effet significatif des traitements sylvicoles n'a été décelé sur l'abondance des autres organismes capturés. Cette campagne d'échantillonnage d'une saison suggère que les coupes de jardinage de faible intensité et les coupes totales de faible superficie dans ce type de forêt engendre peu d'impacts négatifs sur l'abondance de la faune du sol 6 à 12 ans après les traitements.
