Three Parks Savanna Fire-effects Plot Network: Plot-based Fire Severity Associations with Season and Frequency, Kakadu, Litchfield and Nitmiluk National Parks, Northern Territory, Australia, 1994–2013

This data package is a derivative product consisting of a subset of already published data fire severity data packages (from Dr Jeremy Russell-Smith), combined with data indicating time since last fire (from Brett Murphy). These data are used to produce the graphs and conclusions found on pages 355 & 356 of Lindenmayer et. al 2014, Biodiversity and Environmental Change: Monitoring Challenges and Directions.

A total of 220 permanent monitoring plots (40 m x 20 m) were established across three parks (Kakadu, Litchfield and Nitmiluk) in 1994-1995 to monitor biotic change. Of these, 132 plots are located in Kakadu, 41 plots are located in Litchfield, and 47 are located in Nitmiluk. These sample a variety of landform and vegetation type /habitat conditions. A substantial proportion of plots were positioned deliberately at sites likely to reveal environmental dynamics, especially at ecotones and in patches of fire-sensitive vegetation. For example stands of Callitris, sandstone heaths. As well, many plots are located at, or in the near vicinity of, intensively managed sites such as camp-grounds and other tourist destinations.

本数据包为衍生产品，其数据源自已公开发布的火灾严重性数据包（fire severity data packages）子集（源自杰里米·拉塞尔-史密斯博士），并结合了表征距末次火灾时间的数据集（源自布雷特·墨菲）。上述数据用于生成《生物多样性与环境变化：监测挑战与方向》（Lindenmayer等，2014）一书第355、356页中呈现的图表与结论。

1994-1995年间，研究者在卡卡杜、利奇菲尔德与尼特米鲁克三座国家公园内共设立220个永久性监测样地（permanent monitoring plots，规格为40米×20米），以监测生物群落变化。其中132个样地位于卡卡杜，41个位于利奇菲尔德，47个位于尼特米鲁克。这些样地覆盖了多样的地貌、植被类型与生境条件。相当比例的样地被刻意设置在易显现环境动态的区域，尤其是生态交错带（ecotone）与火敏感植被斑块处，例如Callitris（柏木属）林、砂岩灌丛。此外，众多样地位于或邻近诸如露营地、旅游景点等高强度管理区域。作为三座公园稀树草原火灾效应样地网络（Three Park Savanna Fire-effects Plot Network）完整项目的一部分所收集的相关数据包概要，可通过以下链接获取：http://www.ltern.org.au/index.php/ltern-plot-networks/three-parks-savanna
