Three Parks Savanna Fire-effects Plot Network: Plot-based Fire Severity Monitoring, Kakadu National Park, Northern Territory, Australia, 1994–2011

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. The full program assesses fire regimes and their impacts on plant and vertebrate biodiversity components. The program comprises 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. The vegetation data comprises quantitative assessment of all species in three major strata within 800 square metre plots. Faunal assessments are undertaken in the immediate vicinity of respective plots. The occurrence of fire is assessed bi-annually on-ground and satellite derived fire mapping is conducted three times a year. A full inventory of vegetation is undertaken every five years. Terrestrial vertebrates are monitored systematically but on an irregular and less frequent basis. This dataset comprises on-ground assessment of fire occurrence and severity conducted at 132 plots located in Kakadu National Park. Fire occurrence is recorded based on on-ground plot visits, and from aerial ground-truthing assessments of the park’s satellite-based fire mapping programme. Fire severity scores (ordinal values 1–3) are assessed from field photographs. Fire occurrence and severity is assessed in three seasonal periods: early dry season (e), late dry season (L) and wet season (w) for each year. *Note: Plots are located within a National Park and physical access to the plots is restricted. **Note: This package used to be called "Monitoring the impacts of fire regimes on vegetation in northern Australia: Plot based fire severity monitoring data, Kakadu National Park, Northern Territory Australia, 1994–2011", but was relabelled for consistency.

三园稀树草原火灾影响网络（Three Parks Savanna Fire-Effects Network）于1994年成立，核心目标为培训管理人员，助力制定适配区域稀树草原系统的保护型火灾管理适应方案。该完整项目旨在评估火灾制度（fire regime）及其对植物与脊椎动物生物多样性组分的影响。项目包含两个互补模块：一是基于卫星影像解译的火灾历史制图，二是在各覆盖园区的大量永久监测样地中开展植被与动物组分评估。
植被数据采集工作为在800平方米样地内，对三个主要植被层片中的所有物种进行定量评估；动物评估则在对应样地的邻近区域开展。火灾发生情况每半年开展一次地面实地评估，卫星衍生的火灾制图工作每年进行三次。完整植被清查每五年开展一次。陆生脊椎动物采用系统性监测，但监测频率不固定且相对较低。

本数据集涵盖位于卡卡杜国家公园（Kakadu National Park）的132个样地的火灾发生情况与严重程度地面评估结果。火灾发生情况通过实地走访样地，以及对园区卫星火灾制图项目开展的航空实地验证评估两种方式记录。火灾严重程度评分（序数取值1~3）通过野外拍摄的照片进行评估。每年均会在三个季节时段——旱季早期（e）、旱季晚期（L）与雨季（w）——评估火灾发生情况与严重程度。

*注：样地位于国家公园范围内，实地进入样地受到权限限制。
**注：该数据集曾被命名为“澳大利亚北部火灾制度对植被影响监测：基于样地的火灾严重程度监测数据，澳大利亚北领地卡卡杜国家公园，1994–2011”，后为保持一致性进行了重命名。
