Abstract

The Central Appalachian Spruce Restoration Initiative was formed to promote restoration of red spruce Picea rubens forests in Central Appalachia. One goal of the initiative is to increase availability and enhance quality of habitat for wildlife, including the threatened Cheat Mountain salamander Plethodon nettingi. The purpose of this research was to compare microhabitat characteristics between an occupied Cheat Mountain salamander site and early-stage spruce restoration sites, and between four occupied sites and proximal non-detection sites. We found that soil pH was higher and soil moisture was lower at spruce restoration sites compared to the occupied site, and that light intensity, sub-canopy air temperature, and ground-level air temperature were higher in spruce restoration prescriptions with reduced canopy cover. We found that soil moisture was higher at occupied sites compared to proximal non-detection sites, but soil pH was not significantly different. Our study suggests that Cheat Mountain salamanders are associated with low soil pH and high soil moisture, and thus spruce restoration could enhance habitat quality for this species in the long-term.

红杉早期恢复区受威胁的欺骗山蝾螈的微生境关联
“阿巴拉契亚中部云杉恢复倡议”旨在促进阿巴拉契亚中部红杉森林的恢复。该计划的一个目标是增加野生动物栖息地的可用性和质量,包括濒临灭绝的欺骗山蝾螈。本研究的目的是比较欺骗山蝾螈被占领地点与早期云杉恢复地点,以及四个被占领地点与近端未被发现地点之间的微生境特征。结果表明,云杉恢复地土壤pH值高于被占用地,土壤湿度低于被占用地,冠层盖度降低的云杉恢复地光照强度、亚冠层气温和地面气温均高于被占用地。我们发现,被占领的土壤湿度高于近端未检测的土壤,但土壤pH值差异不显著。我们的研究表明,Cheat Mountain salamander与低土壤pH和高土壤湿度有关,因此云杉恢复可以长期改善该物种的栖息地质量。

期刊介绍: Journal of Fish and Wildlife Management encourages submission of original, high quality, English-language scientific papers on the practical application and integration of science to conservation and management of native North American fish, wildlife, plants and their habitats in the following categories: Articles, Notes, Surveys and Issues and Perspectives. Papers that do not relate directly to native North American fish, wildlife plants or their habitats may be considered if they highlight species that are closely related to, or conservation issues that are germane to, those in North America.
