Three Parks Savanna Fire-effects Plot Network: Plot-based Fire Severity Monitoring, Litchfield National Park, Northern Territory, Australia, 2012–2013

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, 41 plots are located in Litchfield. 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. A synopsis of related data packages which have been collected as part of the Three Park Savanna Fire-effects Plot Network’s full program is provided at http://www.ltern.org.au/index.php/ltern-plot-networks/three-parks-savanna.1994—1995年，为监测生物群落动态变化，研究人员在卡卡杜（Kakadu）、利奇菲尔德（Litchfield）与尼特米鲁克（Nitmiluk）三座国家公园内共设立220块规格为40 m × 20 m的永久性监测样地（permanent monitoring plots）。其中41块样地位于利奇菲尔德国家公园内。该样地体系覆盖了多样的地貌、植被类型与生境条件。大量样地被刻意布设于易显现环境动态变化的区域，尤以生态交错带（ecotones）以及火敏感植被斑块为重点布设场景，例如柏松属（Callitris）林分、砂岩灌丛群落。此外，诸多样地坐落于或紧邻集约管理区域，如露营地与其他旅游景区。作为“三座公园稀树草原火烧效应样地网络（Three Park Savanna Fire-effects Plot Network）”完整监测计划的一部分，相关采集数据集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。
