Three Parks Savanna Fire-effects Plot Network (Fauna): Nocturnal Spotlighting Survey, Litchfield National Park, Northern Territory, Australia, 2016

These data are records of all nocturnal spotlighting observations during the 2016 Litchfield survey. A total of 220 permanent monitoring plots were established between 1994-2002 across three parks (Kakadu, Litchfield and Nitmiluk) in the Top End of the Northern Territory, representing the Three Parks Savanna Fire-effects Plot Network. A detailed flora and fauna survey has been conducted at each plot on a 5-6 year cycle to monitor biotic changes. Plots represent a variety of landforms and vegetation types. Litchfield National Park contains 40 plots. In 2016, 20 plots were surveyed for terrestrial vertebrate fauna using a range of survey methods. In addition, at all plots sampling also occurred at a second plot directly adjacent to the traditional plot. At each paired plot 2 x 15 minute surveys was conducted at night using head-torches, on any of the 4 nights available during the 4 day fauna survey period. The spotlight survey area encompassed the standard 50 x 50 m trapping grid and an additional 25 m around all sides.

本数据集收录了2016年利奇菲尔德调查期间全部夜间聚光灯观测记录。1994年至2002年间，北领地顶端区（Top End）的卡卡杜（Kakadu）、利奇菲尔德（Litchfield）与尼特米鲁克（Nitmiluk）三座公园内共设立220个永久监测样地，构建为三公园稀树草原火灾效应样地网络（Three Parks Savanna Fire-effects Plot Network）。各监测样地每5至6年开展一次详尽的动植物调查，以监测生物群落动态变化；样地覆盖多样的地貌与植被类型。利奇菲尔德国家公园（Litchfield National Park）共设置40个监测样地。2016年，研究团队采用多种调查方法，对其中20个样地的陆生脊椎动物开展了调查。此外，所有样地均在紧邻常规样地的第二块配对样地中开展采样。在每对配对样地中，研究人员于4天动物调查期内的任意一晚，使用头灯开展2次各为时15分钟的夜间调查。本次聚光灯调查区域涵盖标准50×50米诱捕网格，以及网格四周向外延伸25米的范围。作为三公园稀树草原火灾效应样地网络完整项目一部分所采集的相关数据集包的概要信息，可通过以下链接获取：http://www.ltern.org.au/index.php/ltern-plot-networks/three-parks-savanna
