Native Vegetation Regulation Condition (2017) - 75m resolution

This replaces NVR2013_COND_V2 and _V2A. Site condition aims to reflect three components - composition, structure and function. In practice, condition is measured through the prism of lifeforms, their cover and species diversity. Measuring the condition of native vegetation recognises that most remaining native vegetation in Victoria has been subject to some disturbances, such as historical land use, grazing or weed and pest animal invasion, and is subsequently reduced in condition; vegetation types vary spatially and temporally; circumstances fluctuate (e.g. seasons, natural disturbance events); degradation and rehabilitation occur; and naturalness is valued.

本数据集替代NVR2013_COND_V2与_V2A版本。植被立地状况旨在体现三大核心要素——组成、结构与功能。实际评估中，该状况通过生物类群、盖度及物种多样性三个维度进行量化。开展本土植被状况评估时需考虑到：维多利亚州现存的绝大多数本土植被均遭受过各类干扰，例如历史土地利用、放牧或杂草与有害生物入侵，其植被状况随之下降；植被类型存在空间与时间异质性；环境条件存在波动（如季节变化、自然干扰事件）；退化与修复过程持续发生；同时自然性亦为重要的评估考量因素。
