Three Parks Savanna Fire-effects Plot Network: Plot-based Fire Severity Monitoring, Litchfield National Park, Northern Territory, Australia, 1995–2011

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至1995年间，为监测生物群落变化，研究人员在卡卡杜（Kakadu）、利奇菲尔德（Litchfield）与尼特米鲁克（Nitmiluk）三座公园内共设立220块永久性监测样地（规格为40m×20m）。其中41块样地设于利奇菲尔德公园内。该批样地涵盖了多样的地貌、植被类型与生境条件。研究团队特意将大量样地布设至易显现环境动态变化的区域，尤其是生态交错带（ecotones）以及火敏感植被（fire-sensitive vegetation）斑块地带，例如澳柏（Callitris）林、砂岩灌丛等。此外，诸多样地坐落于营地等集约管理区域，或其邻近地带，包括各类旅游景区。作为“三公园稀树草原火效应监测样地网络（Three Park Savanna Fire-effects Plot Network）”完整项目的组成部分，相关配套数据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。
