Why study salamander abundance? Salamanders, especially terrestrial salamanders such as<\/p>\n

plethodontidae, are critical components of forest ecosystems and potential indicators of ecosystem changes due to their broad range, high densities and sensitivity to ecosystem changes. Salamanders rely on cool, moist conditions, which can be affected by the change in available leaf litter and coarse woody debris, as well as canopy cover.<\/p>\n
Methods<\/strong> \u201cWith salamanders and other amphibians on the decline, understanding how timber harvest affects these vulnerable species is critical,\u201d Ochs said. \u201cOur findings suggest that timber harvesting techniques that keep some canopy cover may help prevent salamander declines, and even help protect them from drought, a concern as such extreme weather events are growing more common. These findings may be useful to land managers who hope to conduct timber management sustainably without damaging delicate ecosystems and species. Land managers particularly concerned about salamander populations may consider using methods such as shelterwood harvesting rather than more impactful clearcutting.\u201d<\/p>\n Data was collected using artificial cover object grids beginning in the fall of 2007 to determine relative salamander abundance. The first harvests occurred in the winter of 2008. Data was collected in the fall (from mid-September to mid-November) and the spring (from the beginning of March to the end of April) each year through November 2014. Sampling then took place from the fall of 2015 through the spring of 2017 and paused, before resuming in March 2019.<\/p>\n Researchers utilized R for statistical computing and used a before-after-control-impact (BACI) design to examine the effects of harvest type on salamander captures with generalized linear mixed effects models.<\/p>\n Full Article>>><\/a><\/p>\n Resources:<\/strong>
\nThe Hardwood Ecosystem Experiment<\/a> is a long-term, large-scale experimental study of forest management and its impact, which began in 2006. The 100-year project aims to find the ecological and social impacts of long-term forest management on public and private lands in Indiana and the Central Hardwood Region. The HEE features nine units located across the Morgan-Monroe and Yellowwood State Forests, which were analyzed prior to timber harvesting and the years following timber harvests. Units were assigned to utilize even-aged management<\/a>, uneven aged management<\/a> or as unharvested controls<\/a>.<\/p>\n
