摘要

摘要火灾扑灭和硬木入侵是对依赖火灾的山地长叶松生态系统的两大威胁。研究了美国乔治亚州波尔丁县山地长叶松林恢复十年来对林冠、地被和鸟类群落的影响。恢复包括规定的火灾和选择性疏林计划,以减少树冠密度,减少或清除场外物种。达到了几个保护目标,包括恢复特有的树木组成和地被覆盖。鸟类的丰富度和丰度急剧增加,恢复后发现了许多具有高保护价值的灌木和林地依赖物种。我们的研究表明,这些地点很容易恢复,这样的项目可能会产生显著的保护收益。

Changes in Tree Canopy, Groundcover, and Avian Community Following Restoration of a Montane Longleaf Pine Woodland
Abstract. Fire suppression and hardwood encroachment are two of the most significant threats to the imperiled, fire-dependent montane longleaf pine ecosystem. We examined the effects of restoration of a montane longleaf pine forest in Paulding County, Georgia, U.S.A. on tree canopy, groundcover and bird communities over a decade. The restoration included a program of prescribed fire and selective thinning to reduce tree canopy density and reduce or remove offsite species. Several conservation goals were met including the recovery of characteristic tree composition and groundcover. Birds responded with sharp increases in richness and abundance, with many shrub and woodland dependent species of high conservation value detected post-restoration. Our research demonstrates these sites are easily restorable and such projects will likely yield significant gains for conservation.

期刊介绍: The American Midland Naturalist has been published for 90 years by the University of Notre Dame. The connotations of Midland and Naturalist have broadened and its geographic coverage now includes North America with occasional articles from other continents. The old image of naturalist has changed and the journal publishes what Charles Elton aptly termed "scientific natural history" including field and experimental biology. Its significance and breadth of coverage are evident in that the American Midland Naturalist is among the most frequently cited journals in publications on ecology, mammalogy, herpetology, ornithology, ichthyology, parasitology, aquatic and invertebrate biology and other biological disciplines.
