SoE2020: Fragmentation of remnant vegetation

In the most recent 2015–2017 period, the New England Tablelands has experienced the greatest patch density increase (13.4%) and greatest remnant core areas density loss (-2%). The Gulf Plains experienced the greatest increase in the frequency of edges (226), the Brigalow Belt the greatest increase in patches (316) and the Mulga Lands the greatest fragmentation of core areas into smaller core units (400). These examples demonstrate that fragmentation has many guises and they do not necessarily correlate with rates of clearing.

在2015—2017年的最新监测时段内，新英格兰台地（New England Tablelands）的斑块密度增幅最高，达13.4%，同时其残存核心区密度降幅最大，为2%。海湾平原（Gulf Plains）的边缘频率增幅最大，为226；布里加洛带（Brigalow Belt）的斑块数量增幅最高，达316；穆尔加兰兹（Mulga Lands）的核心区破碎为小型核心单元的程度最为显著，数值达400。上述案例表明，景观破碎化存在多种表现形式，且其发生未必与土地清理速率存在关联。
