Mallee Plot Network: Murray Darling Basin data packages, 1994-2018

Aim: Improve understanding of the mechanisms that influence vegetation change, including fire, grazing regimes and climatic variation, and the ability of the ecosystem to sustain its characteristic biota. Key research questions: 1. How do survivorship and fecundity of different plant species vary with time since fire? 2. Do different herbivore species have contrasting effects on standing vegetation? Surveys: - Surveys of vegetation and fauna have been undertaken systematically in relation to fire and herbivore exclusions since 1997. - Automatic weather stations and manual pluviometers recording daily precipitation, evaporation and temperature have been established progressively since 1994.研究目标：深化对影响植被变化的各类机制（包括火灾、放牧制度与气候变异）以及生态系统维持其特有生物群落的能力的认知。 核心研究问题： 1. 不同植物物种的存活率与繁殖力如何随火灾发生后的时长发生变化？ 2. 不同草食动物物种对现存植被的影响是否存在显著差异？ 调查工作： - 自1997年起，针对火灾与草食动物排除实验，系统开展了植被与动物区系调查。 - 自1994年起逐步布设自动气象站与手动雨量计，用于记录每日降水量、蒸发量与气温。
