食果动物和传粉动物是两个功能性动物群体，它们有助于确保恢复景观中植物的基因流动，并加速恢复进程。资源的可利用性被认为是利用恢复地构建动物群落的一个关键因素，但它仍然缺乏研究。我们预计，具有许多植物生长形式的多样性森林，其季节性物候模式较低，将为动物提供更多的资源，而不是植物生长形式较少和季节性物候模式较强的森林。我们研究了原始种植包括高树种多样性的森林。我们研究了所有植物生长形式的资源供应（丰富度和丰富的花朵和水果），在三个不同年龄的恢复网站相比，参考森林，调查植物物候是否与恢复过程中的变化。我们记录了物候数据的生殖植物个体（351种），每月采样超过2年，并发现花和水果的生产已经恢复后，十年的恢复，表明资源提供动物。我们的数据表明，广泛的植物生长形式提供了资源互补的种植树种。树木和非树木之间不同的花物候似乎在非树木物种多样性高的森林中更为明显。我们推荐理想的种植物种的例子，无论是在最初的种植和种植后的丰富。这些管理措施可以最大限度地减少食果和食蜜动物资源短缺的时间，增加恢复生态过程的可能性和恢复地点的可持续性。
Frugivores and pollinators are two functional groups of animals that help ensure gene flow of plants among sites in landscapes under restoration and to accelerate restoration processes. Resource availability is postulated to be a key factor to structure animal communities using restoration sites, but it remains poorly studied. We expected that diverse forests with many plant growth forms that have less‐seasonal phenological patterns will provide more resources for animals than forests with fewer plant growth forms and strongly seasonal phenological patterns. We studied forests where original plantings included high tree species diversity. We studied resource provision (richness and abundance of flowers and fruits) of all plant growth forms, in three restoration sites of different ages compared to a reference forest, investigating whether plant phenology changes with restoration process. We recorded phenological data for reproductive plant individuals (351 species) with monthly sampling over 2 years, and found that flower and fruit production have been recovered after one decade of restoration, indicating resource provision for fauna. Our data suggest that a wide range of plant growth forms provides resource complementarities to those of planted tree species. Different flower phenologies between trees and non‐trees seem to be more evident in a forest with high non‐tree species diversity. We recommend examples of ideal species for planting, both at the time of initial planting and post‐planting during enrichment. These management actions can minimize shortage and periods of resource scarcity for frugivorous and nectarivorous fauna, increasing probability of restoring ecological processes and sustainability in restoration sites.
