Species wood density and the location of planted seedlings drive early-stage seedling survival during tropical forest restoration

1.The success of restoration projects is known to vary widely, with outcomes relating to numerous biotic and abiotic factors. Though many studies have examined the factors associated with long-term restoration success, few have examined which factors impact the establishment of restoration plantings.

2.In Australia's Wet Tropics, we used a large replicated restoration experiment to assess seedling survival for 24 native rainforest species commonly used in local restoration efforts. The experiment allowed for a rigorous assessment of the effects of species functional traits, planting conditions and landscape and local scale biotic and abiotic factors on seedling survival. This study reports on seedling survival between three different time periods of 0 – 4, 4 – 9 and 9 – 31 months post planting.

3.The probability of seedling survival was influenced by multiple factors, varying in importance over time. Across the whole study period, seedlings with high wood density and which were pl...

1. 众所周知，生态恢复项目的成效差异悬殊，其结果与众多生物因子及非生物因子密切相关。尽管已有诸多研究探讨了与长期恢复成效相关的影响因子，但鲜有研究聚焦于哪些因子会对恢复种植的定植过程产生影响。
2. 本研究以澳大利亚湿热带地区为研究区域，依托一项大型重复生态恢复实验，对当地恢复工作中常用的24种本土雨林物种的幼苗存活率进行评估。该实验可严格检验物种功能性状、种植条件以及景观尺度与局地尺度的生物、非生物因子对幼苗存活率的影响。本研究报告了种植后0–4个月、4–9个月及9–31个月三个不同时段的幼苗存活情况。
3. 幼苗存活概率受多种因子调控，其相对重要性随时间动态变化。在整个研究周期内，木材密度较高的幼苗以及……
