Nanangroe Plantation Plot Network: Nocturnal Birds Spotlight Survey, Southwest Slopes, NSW, Australia, 2015

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. Arboreal marsupials survey data for 2015 can be found at http://www.ltern.org.au/knb/metacat/ltern6.9/html. 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. A synopsis of related data packages which have been collected as part of the Nanangroe Plantation Forest Plot Network’s full program is provided at http://www.ltern.org.au/index.php/ltern-plot-networks/nanangroe-plantation.

本夜行鸟类调查数据集包含夜间灯光样带调查工作：各调查点位沿200米固定样带开展单次时长20分钟的调查，每两年重复一次。调查期间需记录观测到的动物物种及其种群丰度，同时记录动物至样带的水平距离以及样带周边的相关距离。若动物栖息于树上，则需额外记录对应树种以及动物离地高度（即地面至动物的垂直距离）。此外，夜间灯光样带调查过程中亦可通过鸣叫声侦测到夜行鸟类。

纳南格罗（Nanangroe）研究的核心目标是：当周边景观基质由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，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（参考文献：Lindenmayer DB, Cunningham RB, MacGregor C, Tribolet C & Donnelly CF. 2001, 《一项关于林地残存物中动物的景观基质效应的前瞻性纵向研究：实验设计与基线数据》，载于《Biological Conservation（生物保护）》，第101卷第2期，第160页）。

本研究区域位于布里因杰克湖（Lake Burrinjuck）西侧的新南威尔士州（New South Wales，缩写NSW）西南坡地，涵盖4处外来松类人工林（纳南格罗、科特韦、东邦贡戈与邦贡戈），以及毗邻这些人工林的私有土地。

自1998年起，研究团队对所有调查点位的植被结构、植被覆盖度以及选定的脊椎动物类群开展重复采样，由此构建了长期监测数据集。
