brenda.mccomb@oregonstate.edu Creator 2011-09-14 Previous descriptive and associative research approaches have identified associations between the amount of coarse woody debris (CWD) and either the occurrence or abundance of certain species of forest floor mammals and amphibians (e.g., Aubry et al. 1988, McComb et al. 1993). Managers are using information such as this along with observations regarding nutrient exchange sites around coarse woody debris to develop management guidelines for retention of woody debris following harvest. However, the hypothesis that retention of high levels of woody debris will result in the high numbers of certain species of forest floor vertebrates has not been tested in an experimental manner. populations primary production coarse woody debris amphibians mammals small mammals LTER controlled vocabulary Long-Term Ecological Research (LTER) Andrews Experimental Forest site thesaurus populations primary production LTER core research areas Data Use Agreement: The re-use of scientific data has the potential to greatly increase communication, collaboration and synthesis within and among disciplines, and thus is fostered, supported and encouraged.

No treatments (control), high CWD retention, and low CWD retention. We expect to provide managers with information that might allow them to identify the levels and types of woody debris that should be retained following harvest on similar sites in the Willamette National Forest and central Cascades region.

(541) 737-8480 lterweb@fsl.orst.edu http://andrewsforest.oregonstate.edu/ Field Methods - WE026 Two types of traps were used to sample small mammals and amphibians owing to trap selectivity of species (McComb et al. 1993). We used pitfall traps to sample shrews and amphibians. We established one pitfall trap (double-deep #10 can) within one meter of each trap-station center. The top of traps was flush with ground level. Holes were punched in the bottom of the traps for drainage of rain water. To minimize trap deaths, we placed a small amount of moss on the bottom of the traps to absorb moisture and polyfiber batting on top of the moss for insolation. Additionally, we placed a pint-size juice carton filled with polyfiber batting in the traps and provided a small portion of bait. Bait consisted of a mixture of peanut butter, rolled oats, and sunflower seeds. Additionally, rodent chow and suet were placed in pitfall traps as a food source for shrews. When in use, a plastic funnel made from a 2-lb margarine tub was placed in the neck of the pitfall trap to prevent escape of captures. Between trapping periods, pitfall traps were filled in with sticks or rocks to prevent animals from entering. Sherman live-traps (7.62 x 8.89 x 22.86 cm) were used to primarily record rodents. These traps were also baited and filled as much as possible with polyfiber batting, and placed inside empty one-half gallon milk cartons to shelter captures from rain. During a trapping period, we placed two traps within two meters of a trap station, one on each side of the transect. Sherman traps were removed when a plot was not being trapped. All three treatments within a replicate block were simultaneously trapped for two consecutive weeks, with some exceptions. Pitfall and Sherman traps were trapped for eight consecutive nights. Time-constraint searches were additionally conducted for amphibians during the 1995 trapping season. This sampling was also attempted in spring of 1997 in addition to destructive sampling in a non- experimental stand to evaluate the effectiveness of this technique. Given the very low observation rate (ca. 1 observation/2 hrs of searching), this technique was not used in subsequent years. For each capture, we recorded station number and trap type, body mass, body and tail length, and sex and reproductive condition where possible. Captures were ear tagged with Monel #1 ear tags except for species of shrews with too small of external ears and amphibians which were toe clipped. Tag or toe number were recorded for each capture as was capture status (i.e., new, recapture). Animals were released at the site of capture. We attempted to revive all torpid animals by placing them in the pocket of field vests containing a chemical heating pad and polyfiber batting. When possible, we fed animals sugar water with an eye dropper to aid in their recovery. If individuals were not revived within several hours, they were taken to the crew's quarters and provided ample food and water and insolation. Surviving animals were released as soon as possible at the site of capture. All dead captures were frozen and made available to the OSU Fish and Wildlife Department's study skin collection. We also recorded numbers of disturbed or closed traps for calculating comparable measures of captures per trap night among plots and among trapping years. Sampling frequency: seasonal As part of the Long-term Ecological Productivity (LTEP) study,we are monitoring the response of ground-dwelling vertebrates to three levels of coarse woody debris treatments - no treatments (control), high CWD retention, and low CWD retention. Three replicates (i.e., blocks) of the three treatments are sampled for ground-dwelling vertebrates. We sampled ground-dwelling vertebrates in the LTEP plots (located in the Isolation Block section of the Willamette National Forest) receiving the mid-seral, high and low coarse woody debris treatments and respective control plots for a total of nine plots (Table 1). Stands were naturally regenerated 80-100 yrs ago. The low CWD treatment was essentially a clearcut with the removal of large downed wood. The high CWD treatment was a clearcut but with 20% of the original basal area felled and left on site. Pre-treatment sampling on all plots was conducted October-November 1995. Another year of pre-treatment sampling was possible on replicate II and III plots during October-November 1996. Plots in replicate I were harvested after the 1995 vertebrate sampling and were sampled Fall 1996 to measure post-treatment effects. However, felling of residual stems did not occur in the high CWD treatment plot. Sampling was conducted in 1997 after harvest of all treatment plots. Again, however, the high CWD treatments were not fully implemented; residual stems remained on these plots until 1998. Sampling was conducted in 1999-2000 and after all treatments were fully implemented. Four 100-m long transects were established in each stand, with trap stations spaced 10 m apart along a transect. Transects were distributed to adequately sample a stand without traversing the centrally located mensuration plots. Transects were equidistant from the stand perimeter and the perimeter of the mensuration plot. Bearing and distance from the corners of mensuration plots to transects, and between transects was recorded for future reference. Stations were flagged with blue and white striped flagging on branches. Stations were additionally marked with wire flagging during the Fall 1996 sampling effort.

Andrews Experimental Forest is a living laboratory that provides unparalleled opportunities for the study of forest and stream ecosystems in the central Cascade Range of Oregon. Since 1980, as a part of the National Science Foundation Long Term Ecological Research (NSF-LTER) program, the Andrews Experimental Forest has become a leader in the analysis of forest and stream ecosystem dynamics. Long-term field experiments and measurement programs have focused on climate dynamics, streamflow, water quality, and vegetation succession. Currently researchers are working to develop concepts and tools needed to predict effects of natural disturbance, land use, and climate change on ecosystem structure, function, and species composition. The Andrews Experimental Forest is administered cooperatively by the USDA Forest Service Pacific Northwest Research Station, Oregon State University and the Willamette National Forest. Funding for the research program comes from the National Science Foundation (NSF), US Forest Service Pacific Northwest Research Station, Oregon State University, and other sources. Data were provided by the HJ Andrews Experimental Forest research program, funded by the National Science Foundation's Long-Term Ecological Research Program (DEB 2025755), US Forest Service Pacific Northwest Research Station, and Oregon State University. National Science Foundation: DEB1440409 The Andrews Forest is situated in the western Cascade Range of Oregon, and covers the entire 15,800-acre (6400-ha) drainage basin of Lookout Creek. Elevation ranges from 1350 to 5340 feet (410 to 1630 m). Broadly representative of the rugged mountainous landscape of the Pacific Northwest, the Andrews Forest contains excellent examples of the region's conifer forests and associated wildlife and stream ecosystems. These forests are among the tallest and most productive in the world, with tree heights of often greater than 250 ft (75 m). Streams are steep, cold and clean, providing habitat for numerous aquatic organisms. 1 WE02601 Captures: WE02601.csv 414979 c1f672f8e39b9188ad1bd448e5a6d2fa 1 \r\n column , "
