农业景观中的残木和森林片断可以成为促进森林恢复的重要繁殖体来源。然而，许多研究只是将周围景观中的森林覆盖率量化为百分比，很少注意物种组成，因此未能发现对补充模式的影响。我们评估的相对重要性的空间分布和生活史特征的77个树种在景观尺度上的招聘模式在一个良好的复制长期恢复研究在南部哥斯达黎加。我们在8个重复恢复地块周围的100 m缓冲区中普查和绘制了潜在的母树，并量化了每个地块内的相应树木新兵。我们评估了母树丰富度，物种生活史特征（种子大小，传播模式），树木大小（胸径，高度）和恢复地块的距离如何影响粗（地块：50 × 50 m）和细（样方：3 × 3 m）空间尺度的补充。在恢复地块100 m范围内存在母树导致潜在平均招募增加10倍。母树丰度也是补充密度的重要驱动因素，特别是对于大种子（≥ 5 mm）的动物源物种，在观察到的母树丰度范围内，补充密度增加了5倍。母树丰富和接近之间的相互作用表明，母树丰富的招聘密度的影响是重要的，但随着距离的增加，从恢复地块减弱。在精细的空间尺度上，接近一致的重要性，最近的潜在母树的高度和胸径也影响招聘丰富，但种子大小的反应不同。结果突出了残余植被组成的重要性，邻近退化的栖息地的恢复，强调附近的残余森林和孤立的树木可以发挥本地化的生物多样性的持久性的巨大作用。
Remnant trees and forest fragments in agricultural landscapes can be important sources of propagules to facilitate forest recovery. However, many studies simply quantify forest cover in the surrounding landscape as a percentage, with little attention given to species composition, and subsequently fail to detect an effect on recruitment patterns. We assessed the relative importance of the spatial distribution and life‐history traits of 77 tree species on recruitment patterns at a landscape scale in a well‐replicated long‐term restoration study in southern Costa Rica. We censused and mapped potential mother trees in a 100‐m buffer surrounding eight replicate restoration plots and quantified respective tree recruits within each plot. We assessed how mother tree abundance, species life‐history characteristics (seed size, dispersal mode), tree size (DBH, height) and distance to restoration plot affected recruitment at coarse (plot: 50 × 50 m) and fine (quadrat: 3 × 3 m) spatial scales. The presence of a mother tree within 100 m of a restoration plot resulted in a 10‐fold increase in potential mean recruitment. Mother tree abundance was also an important driver of recruit density, and particularly so for large‐seeded (≥ 5 mm) zoochorous species with a fivefold increase in recruit density across the observed mother tree abundance range. An interaction between mother tree abundance and proximity demonstrated that the effect of mother tree abundance on recruit density was important but waned with increasing distance from restoration plots. At the fine spatial scale, proximity was uniformly important; height and DBH of the closest potential mother tree also affected recruit abundance but responses differed by seed size. Results highlight the importance of remnant vegetation composition to the recovery of adjacent degraded habitats, underscoring the outsized role nearby remnant forest and isolated trees can play for the persistence of localized biodiversity.
