| Summary: | abundance in SMZs implemented within clearcuts. Both abundance of one species. Clearcutting increased abundance blocks, bisected lengthwise by an intermittent stream, were clearcut plots. Two species increased in abundance in SMZs control and both timber harvesting treatments and between SMZ cutting appeared to have the least harmful effect on cutting did not decreased abundance of any species. days, between 24 January 1993 and 22 June 1994. During this decreased in abundance in SMZs of either selection-cut or detrimentally impacted species to repopulate the new emerging diversities than control SMZS. In the short-term, genotypic double-ended-wire funnel traps. Traps were checked for 180 effect on the remaining 13 species. Clearcutting decreased effectiveness of a streamside-management zone (SMZ) forest. forests by allowing heterogeneity in stand age and habitat. from each bank of the intermittent stream and subjected only greatest impact after timber harvest, while more generalist herpetofauna populations were evaluated. Also, the herpetofauna, as this method maintains the essence of natural Impacts of selection-cutting and clearcutting on local implemented within harvested areas was assessed. Research implemented within selection-cuts. Two species increased in multiple comparison tests for the 15 most commonly captured of 3 species and had no impact on I I species. No species preventing meaningful statistical evaluation. Selection- provide a refugium and may act as centers of dispersal for randomized block design experiment was used. Three 24-ha selection-cut and clearcut Sws possessed greater species selection-cut and clearcut treatments possessed greater selection-cut, and clearcut. A SMZ was established 20. 1-m Selection-cutting increased abundance of 2 species and had no species diversities than control areas. In addition, species of seasonally-flooded-bottomland forests suffer species remain stable or increase in abundance. Selection- species were captured. Differences in abundance between species. The remaining 23 species were rarely encountered, Station, located in southeast Tyler County, Texas. A subdivided into three (8-ha) plots consisting of a control, The continued use of SMZs is recommended. These areas time, 8194 individual reptiles and amphibians comprising 38 to limited selection-cutting. Herpetofauna were censused treatments were analyzed utilizing a one-way ANOVA and using 144 drift fence arrays, consisting of pit-fall and was conducted at Forest Lake Forest and Wildlife Research within control and SMZ within both timber harvesting |
