资源简介:
This package represents all data from Burramys trapping surveys within the Alpine Long Term Monitoring - Burramys Population Surveys project. The surveys began in 1982, and the most recent addition is from 2017. This data package contains data collected at a sub-set of the 481 long term monitoring plots which have been established in Australian Alps and in Tasmania. The sampling regime within the Victorian Network generally consists of multiple randomly positioned transects within sites, (rather than ‘plots’ sensu stricto), with each site, and/or transect geo-located. Point quadrats are taken at fixed intervals along each transect. The number of transects within sites, and sampling frequency varies from annual to decadal, depending on site and purpose. This general array of sampling transects, point quadrats along transects and floristic quadrats is consistent between grassland and snowpatch monitoring sites, although the number of transects and floristic quadrats needed to detect change in key variables (vegetation cover, bare ground, etc) at each site varies over time. There are also long-term monitoring sites in wetlands. The Victorian Alpine Plot Network research plots are revisited on a 2-10 years basis. A synopsis of related data packages which have been collected as part of the Victorian Alpine Plot Network’s full program is provided at http://www.ltern.org.au/index.php/ltern-plot-networks/victorian-alpine
本数据包涵盖高山长期监测(Alpine Long Term Monitoring)——山袋貂属(Burramys)种群调查项目下的全部山袋貂诱捕调查数据。该调查工作始于1982年,最新一批数据采集于2017年。
本数据包收录了在澳大利亚阿尔卑斯山区与塔斯马尼亚地区设立的481处长期监测样地中的部分样地所采集的数据。
维多利亚州监测网络的采样方案通常为在样地内布设多条随机设置的样线,而非严格意义上(sensu stricto)的样地,并对每处样地及/或样线进行地理定位。沿每条样线以固定间隔设置点样方框(point quadrats)。
样地内的样线数量与采样频率依样地类型与调查目的而异,从每年一次至十年一次不等。
尽管各监测样地为检测关键变量(植被盖度、裸地占比等)变化所需的样线与植物样方(floristic quadrats)数量会随时间动态调整,但草原与积雪斑块监测样地所采用的采样框架——即样线、沿样线布设的点样方框以及植物样方——整体保持一致。此外,该项目还设有湿地长期监测样地。
维多利亚州高山样地网络的研究样地每2至10年被重新开展一次调查。
