Three Parks Savanna Fire-effects Plot Network (Fauna): Nocturnal Spotlighting Survey, Nitmiluk National Park, Northern Territory, Australia, 2015

These data are records of all nocturnal spotlighting observations during the 2015 Nitmiluk 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.

Nitmiluk National Park contains 46 plots, each with a paired plot located within 1 km of the primary plot. In 2015, 23 paired plots were surveyed for terrestrial vertebrate fauna using a range of survey methods.

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.

本数据集为2015年尼特米鲁克（Nitmiluk）调查期间所有夜间聚光灯观测的完整记录。
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）与尼特米鲁克三座国家公园内，共设立220个永久监测样地，构成三公园稀树草原火灾效应样地网络（Three Parks Savanna Fire-effects Plot Network）。各监测样地均以5至6年为周期开展详细的动植物调查，以监测生物群落动态变化；样地覆盖多种地貌与植被类型。
尼特米鲁克国家公园内设有46个主样地，每个主样地配套设置1个距其1公里范围内的配对样地。2015年，研究团队采用多种调查方法，对其中23组配对样地的陆生脊椎动物开展了调查。
在每组配对样地中，于为期4天的动物调查时段内的任意4个夜晚，使用头灯开展2次时长各15分钟的夜间调查。本次聚光灯调查的范围涵盖标准50×50米诱捕网格及其四周向外延伸25米的区域。
