Much of the remarkable plant species diversity of the Southwest Australian Floristic Region can be attributed to high diversity of the understorey in its forests and woodlands, including 400–600 understorey species per km 2 in the Northern Jarrah Forest alone. Consequently, returning species diversity is a key challenge for post-mining ecological restoration in the region. Each year, Alcoa of Australia undertakes restoration of mined areas within the Northern Jarrah Forest with a goal of returning a self-sustaining jarrah forest ecosystem. To meet this goal, it is important to understand long-term (i.e. > 20 years) trajectories of vegetation development and the restoration practices that direct species diversity outcomes. Here, we report the results of several experiments, the oldest of which is 45 years of age, which together demonstrate significant longer-term effects on understorey species diversity of restoration practices determining initial conditions including topsoil handling, fertiliser application, seeding rates of large legumes, and tree (overstorey) species stocking rates. Our research highlights (1) that ‘historical contingency’ can determine the trajectory of jarrah forest restoration and (2) that longer-term studies are critical as they give a different, sometimes conflicting, perspective to short-term datasets. Notably, after 27 years, we found an inverse relationship between plant cover and P fertilisation, where plant cover was highest in the in the absence of P fertiliser and lowest at the uppermost P amendment rate. We also found that the long-accepted Initial Floristics Model of succession does not fit well with our data. Our overall findings are likely useful to restore understorey diversity to woodlands, forests, and abandoned farmlands elsewhere in the region.
澳大利亚西南区植物种类的显著多样性可归因于其森林和林地中林下植被的高度多样性，仅在北贾拉赫森林中，每平方公里就有400-600种林下植被。因此，物种多样性的回归是该地区采矿后生态恢复的关键挑战。每年，澳大利亚的美国铝业公司(Alcoa of Australia)都会对北亚拉赫森林(Northern Jarrah Forest)内的矿区进行恢复，目标是恢复一个自我维持的亚拉赫森林生态系统。为了实现这一目标，了解植被发展的长期(即> 20年)轨迹和直接影响物种多样性结果的恢复实践是很重要的。在这里，我们报告了几个实验的结果，其中最老的是45年的实验，这些实验共同证明了恢复措施对林下物种多样性的显著长期影响，这些恢复措施决定了初始条件，包括表土处理、施肥、大型豆科植物的播种率和树木(上层)物种的放养率。我们的研究强调(1)“历史偶然性”可以决定jarrah森林恢复的轨迹;(2)长期研究至关重要，因为它们为短期数据集提供了不同的、有时是相互矛盾的视角。值得注意的是，27年后，我们发现植物覆盖与施磷肥呈反比关系，在不施磷肥时植物覆盖最高，在施磷肥修正率最高时最低。我们还发现，长期接受的演替初始区系模型与我们的数据不太吻合。我们的总体发现可能有助于恢复该地区其他地方林地、森林和废弃农田的林下植被多样性。
