Nanangroe Plantation Plot Network: Arboreal Marsupial Spotlight Survey, Southwest Slopes, NSW, 1999+

This arboreal marsupial 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. Sightings of exotic species (e.g. foxes, rabbits and pigs), as well as some non-arboreal (e.g. kangaroos) 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 marsupial）调查数据集包含夜间灯光样线调查（spotlight survey）数据：各调查样点均沿200米固定样带开展调查，单次调查时长为20分钟，调查频率为每两年一次。调查人员将记录动物与样带沿线及邻近区域的距离；若动物栖息于树木之上，则同步记录其所在的树木种类与动物高度（即动物距地面的垂直距离）。此外，数据集同时收录外来物种（如狐狸、野兔与野猪）以及部分非树栖类群（如袋鼠）的目击记录。
南南格鲁（Nanangroe）研究的核心目标，是直接量化当周边景观基质（landscape matrix）从半开垦放牧型景观转变为以外来软木人工林为主导的景观时，林地脊椎动物类群的变化及其与生境变量的关联关系（Lindenmayer DB, Cunningham RB, MacGregor C, Tribolet C, Donnelly CF. 2001. 林地残存群落中景观基质对动物区系的影响前瞻性纵向研究：实验设计与基线数据. 生物保护（Biological Conservation）, 101(2): 160）。
本研究区域位于新南威尔士州（NSW）布里宁库克湖（Lake Burrinjuck）西侧的西南坡地带，涵盖4处外来松类人工林（南南格鲁、科特韦、东邦贡戈与邦贡戈），以及毗邻这些人工林的私人领地。自1998年起，研究人员对所有样点的植被结构、植被覆盖度以及选定的脊椎动物类群开展重复采样，由此形成了长期观测数据集。
