Comparison of historical data with recent surveys of grasslands across Victoria’s basalt plain reveals a substantial decline in native annual forbs. Eleven of the 35 species once common in this ecosystem have not been recorded for decades. The near loss of a lifeform from an ecosystem should ring alarm bells, but it seems the warning has passed largely unnoticed. Is this due to ‘shifting baseline syndrome’? What has caused this quiet decline in biodiversity, and what does it teach us about management and restoration?

维多利亚玄武岩平原草原被遗忘的年度草

将历史数据与最近对维多利亚玄武岩平原草原的调查进行比较，可以发现本地一年生杂草的数量大幅下降。曾经在这个生态系统中常见的 35 种物种中有 11 种已经几十年没有记录了。生态系统中生命形式的濒临灭绝应该敲响警钟，但似乎警告已经在很大程度上被忽视了。这是由于“转移基线综合症”吗？是什么导致了生物多样性的这种悄然下降，它在管理和恢复方面教会了我们什么？
