Nanangroe Plantation Plot Network: Nocturnal Birds Spotlight Survey, Southwest Slopes, NSW, Australia, 2013

This nocturnal birds survey data package comprises spotlight surveys conducted every two years along 200 metre fixed transects at each site for 20 minutes per site. Animal species and abundance are recorded. Distances along and adjacent to a transect are also recorded. If animals are up on a tree, tree species and animal height (distance from the ground to the animal) are also recorded. Nocturnal birds are also detected by the calls during spotlighting.

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.

本夜行性鸟类调查数据集包含灯光样线调查数据：于每个样点沿200米固定样带开展每两年一次的调查，单个样点的调查时长为20分钟。调查记录动物物种与个体多度，同时记录样带沿线及邻近区域的距离参数。若动物停栖于树上，则需额外记录树种及动物体高（地面至动物的垂直距离）。此外，灯光调查过程中还可通过鸣叫声侦测夜行性鸟类。

纳南格罗（Nanangroe）研究的核心目标为：当周边景观基质从半清理放牧景观转变为以外来软木人工林为主的景观时，直接量化林地脊椎动物群落的变化及其与生境变量的关联（Lindenmayer DB, Cunningham RB, MacGregor C, Tribolet C & Donnelly CF, 2001, 《林地残存物中景观基质对动物区系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）。

本研究区域位于巴林杰克湖（Lake Burrinjuck）西侧的新南威尔士州（NSW）西南坡地带，涵盖4处外来松树人工林（纳南格罗、科特韦、东本贡戈及本贡戈），以及毗邻这些人工林的私有地块。自1998年起，研究团队对所有样点的植被结构、植被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。
