Nanangroe Plantation Plot Network: Arboreal Marsupial Spotlight Survey, Southwest Slopes, NSW, 2013

This arboreal marsupials survey data package comprises spotlight surveys conducted every two years along 200 metre fixed transects at each site for 20 minutes per site. Distances along and adjacent to a transect are recorded. If animals are in a tree, tree species and animal height (distance from the ground to the animal) are also recorded.

The principle objective of the Nanangroe study is to directly quantify changes in woodland vertebrate assemblages and their relationships with habitat variables when the surrounding landscape matrix is converted from a semi-cleared grazing landscape to a landscape dominated by an exotic softwood plantation (Lindenmayer, DB, Cunningham, RB, MacGregor, C, Tribolet, C & Donnelly, CF 2001, ‘A prospective longitudinal study of landscape matrix effects on fauna in woodland remnants: experimental design and baseline data’, Biological Conservation, vol 101 no 2, p. 160).

The study area is located in the Southwest slopes of NSW west of Lake Burrinjuck and includes four exotic Pine Plantations (Nanangroe, Cotway, East Bungongo and Bungongo), as well as private properties adjacent those plantations. Repeated sampling of the vegetation structure and cover and selected vertebrate groups on all sites from 1998 has created a long term dataset.

本树栖有袋类（arboreal marsupials）动物调查数据集，包含夜间聚光灯调查（spotlight surveys）方法：每两年在各调查点沿200米固定样带（fixed transects）开展调查，单调查点单次调查时长为20分钟，记录样带沿线及毗邻区域内动物的位置距离。若观测到动物栖息于树木上，则同步记录树种及动物栖高（即动物距地面的垂直距离）。

南纳格罗（Nanangroe）研究的核心目标，是直接量化当周边景观基质（landscape matrix）由半开垦放牧景观转变为以外来软木人工林（exotic softwood plantation）主导的景观时，林地脊椎动物群落（woodland vertebrate assemblages）的动态变化及其与生境变量（habitat variables）之间的关联（Lindenmayer等，2001：《林地残存斑块中景观基质对动物的影响前瞻纵向研究：实验设计与基线数据》，《生物保护（Biological Conservation）》，第101卷第2期，第160页）。

本研究区域位于布里金杰克湖（Lake Burrinjuck）西侧的新南威尔士州（NSW）西南坡地，涵盖4处外来松人工林（Pine Plantations），分别为南纳格罗、科特韦、东本贡戈及本贡戈，同时包含毗邻这些人工林的私人产权地块。自1998年起，研究团队对所有调查点的植被结构、覆盖度及选定的脊椎动物类群开展重复采样，由此构建了长期监测数据集。
