Three Parks Savanna Fire-effects Plot Network: Plot-based Vegetation Sampling Data, Northern Territory, Australia, 1994-2016

Abstract: The Three Parks Savanna Fire-Effects Network was established in 1994 with the primary aim of training management staff and assisting with the development of adaptive approaches to conservation-based fire management in regional savanna systems. This dataset comprises the vegetation sampling data from the 220 plots located across the Three Parks Savanna Fire-effects Plot Network, of which 133 are in Kakadu National Park, 41 in Litchfield National Park and 46 in Nitmiluk National Park. The vegetation data consists of the quantitative assessment of all species in three major strata within 800 square meter plots. Plots are positioned to investigate environmental changes in areas of interest by land managers and may reveal environmental dynamics. Plots are located in a variety of landform and vegetation type / habitats and conditions, and may be in vicinity of intensively managed sites such as camp grounds and other tourist attractions. Areas also include ecotones and patches of fire-sensitive vegetation such as stands of Callitris and sandstone heaths. The full program assesses fire regimes and their impacts on plant and vertebrate biodiversity components. The program consists of two complementary elements – mapping of fire histories based upon interpretation of satellite imagery, and assessment of vegetation and faunal components at a large series of permanent monitoring plots located across respective parks. *Note: Plots are located within a National Park and physical access to the plots is restricted.

Sampling method: Monitoring plot establishment and resampling exercises are conducted either at the end of the wet season period to facilitate flora identification (i.e. before herbaceous plants wither, or the vegetation is burnt), or late dry season due to access logistical restictions, for example floodplain sites. Sampling is designed to assess all levels of habitat strata including non-woody and woody species diversity.

This package has chosen to use the following names from the NTFlora database:

• Fimbristylis miliacea (instead of Fimbristylis quinquangularis)
• Fimbristylis pterygosperma (instead of Fimbristylis pterigosperma)
• Sauropus lissocarpus (instead of Phyllanthus arnhemicus)
• Sauropus lissocarpus instead of Phyllanthus arnhemicus
• Cartonema sp. antrorse
• Cartonema sp. pedicellate
• Haemodorum sp. red flowers (instead of Haemodorum sp. Red flowers)
• Utricularia nivea (instead of Utricularia sp. Small white)
• Antidesma ghesaembilla (instead of Antidesma ghaesembilla)
• Melastoma malabathricum • Melastoma malabathricum subsp. malabathricum (instead of Melastoma affine)

Study exten: The plots were established in 1995 at the end of the wet season period to facilitate flora identification before herbaceous plants senesce. The full floristic sampling is timetabled to occur every five years. There have been up to 5 different time sets of data collected but not every site has been revisited each time. Fire recording by photo and ground observation is undertaken at the end of every fire season early, late and wet season.

**Note plot 95 in Kakadu National Park was lost after the first visit (T1).

Project funding: SBetween 2012 and 2018 this project was part of, and funded through the Long Term Ecological Research Network (LTERN) a facility within the Terrestrial Ecosystem Research Network (TERN) and supported by the Australian Government through the National Collaborative Research Infrastructure Strategy.

This project has also received funding through Parks Australia, NT Parks & Wildlife Service, Tropical Savannas CRC, and Darwin Centre for Bushfires Research (Charles Darwin University).

摘要：三公园稀树草原火灾效应网络（Three Parks Savanna Fire-Effects Network）于1994年成立，核心目标为开展管理人员培训，并助力研发适用于区域稀树草原（savanna）系统的保护性火灾管理自适应方案。本数据集涵盖分布于三公园稀树草原火灾效应样地网络（Three Parks Savanna Fire-effects Plot Network）内220个样地（plot）的植被采样数据，其中133个样地位于卡卡杜国家公园（Kakadu National Park）、41个位于利奇菲尔德国家公园（Litchfield National Park）、46个位于尼特米鲁克国家公园（Nitmiluk National Park）。植被数据包含对800平方米样地内三大植被层（stratum）中所有物种的定量评估。样地的布设旨在帮助土地管理者探究目标区域的环境变化，并可揭示环境动态。样地分布于多种地貌、植被类型/生境及环境条件中，可能紧邻营地及其他旅游景点等高强度管理区域。调查区域还包含生态交错带（ecotone）以及火灾敏感植被斑块，例如柏木属（Callitris）林和砂岩灌丛（heath）。该完整项目旨在评估火制度（fire regime）及其对植物和脊椎动物生物多样性组分的影响。项目包含两个互补组成部分：一是基于卫星影像解译绘制火灾历史分布图，二是对各公园内一系列永久监测样地的植被与动物区系组分开展评估。*注：样地均位于国家公园内，实地进入样地受到限制。

采样方法：监测样地的布设与重采样工作可选择在湿季末期开展，以便于识别植物区系（flora）（即在草本植物（herbaceous plant）枯萎或植被被烧毁前完成）；或因通行后勤限制选择在旱季后期开展，例如泛滥平原（floodplain）样地。采样设计旨在评估所有生境层的多样性，包括非木本与木本物种的多样性。

本数据集选用了北领地植物数据库（NTFlora database）中的以下物种名称：
• Fimbristylis miliacea（替代原名为Fimbristylis quinquangularis）
• Fimbristylis pterygosperma（替代原名为Fimbristylis pterigosperma）
• Sauropus lissocarpus（替代原名为Phyllanthus arnhemicus）
• Sauropus lissocarpus（替代原名为Phyllanthus arnhemicus）
• Cartonema sp. antrorse
• Cartonema sp. pedicellate
• Haemodorum sp. red flowers（替代原名为Haemodorum sp. Red flowers）
• Utricularia nivea（替代原名为Utricularia sp. Small white）
• Antidesma ghesaembilla（替代原名为Antidesma ghaesembilla）
• Melastoma malabathricum 及其原亚种Melastoma malabathricum subsp. malabathricum（替代原名为Melastoma affine）

研究范围：样地于1995年湿季末期布设，以便在草本植物衰老前完成植物区系识别。完整的植物区系采样计划每五年开展一次。目前已收集最多5个不同时期的数据集，但并非每个样地每次重采样都被覆盖。火灾记录通过照片拍摄与地面观测开展，在每个火灾季的初期、末期及湿季末期进行。

**注：卡卡杜国家公园的95号样地在首次采样（T1）后遗失。
