Tree species that produce resources for fauna are recommended for forest restoration plantings to attract pollinators and seed dispersers; however, information regarding the flowering and fruiting of these species during early growth stages is scarce. We evaluated the reproductive phenology of animal‐dispersed tree species widely used in Atlantic Forest restoration. We marked 16 animal‐dispersed tree species in 3‐ to 8‐year‐old forest restoration plantings in Itu‐São Paulo, southeast Brazil. We noted the age of the first reproductive event, flowering and fruiting seasonality, percentage of trees that reached reproductive stages, and intensity of bud, flower, and fruit production for each species. Flowering and fruiting are seasonal for most species; only two, Cecropia pachystachya and Ficus guaranitica, exhibited continuous flowering and fruiting throughout the year; we also identified Schinus terebinthifolia and Dendropanax cuneatus fruiting in the dry season during resource scarcity. Therefore, we recommend all as framework species, that is, species that are animal‐dispersed with early flowering and fruiting potential, for forest restoration. Further, we recommend identifying and planting similar animal‐dispersed tree species that produce fruits constantly or in the dry season to maximize fauna resource availability throughout the year in tropical forest restoration plantings.

幼林恢复造林中动物分散物种的非连续生殖物候

建议为森林动植物种植可为动物提供资源的树木,以吸引传粉媒介和种子传播者;然而,关于这些物种在早期生长阶段开花和结果的信息很少。我们评估了广泛用于大西洋森林恢复的动物分散树种的生殖物候。我们在巴西东南部伊图圣保罗的3至8岁森林恢复种植园中标记了16种动物分散的树种。我们注意到了第一个生殖事件的年龄,开花和结果的季节性,到达生殖阶段的树木的百分比以及每种物种的芽,花和果实产量的强度。大多数物种的开花结果是季节性的。只有两个,Cecropia pachystachya榕树全年开花并结实。我们还确定了在资源稀缺的干旱季节,中华绒螯蟹中华落叶松结果实。因此,我们建议将所有物种作为框架物种,即具有早期开花和结果潜力的动物分散物种,以恢复森林。此外,我们建议识别并种植在自然界中恢复生长的常年或在干旱季节结实的类似动物分散树种,以最大程度地利用动物资源。
