Seed rain sampling in a secondary subtropical forest invaded by Ligustrum lucidum subject to experimental management, 2021-2023

These seed rain data were collected during a field experiment evaluating the management of secondary forests affected by Ligustrum lucidum invasion. The experiment established six permanent plots of 240 metres by 140 meters each (3.36 hectares, see related dataset). Plots were established in pairs (3 pairs in total), where one element of the pair was assigned as the control scenario (no actions applied), and the other was the treatment (L. lucidum control and native tree planting). After implementing the treatment, 288 seed traps were established, each one being a 0.5x0.5-metre quadrat of mosquito mesh suspended by stakes at 0.30 metres above the ground. In total 48 seed traps per plot were deployed, allocating 12 seed traps to each of the 4 transects within each of the six permanent plots. Every two weeks, all the fruits and seeds were collected that had fallen on the traps, and then we identified each item at the species level when it was feasible. They were identified using field guides, a reference collection of fruits and seeds gathered from local field sites and supported by local experienced taxonomists. Also recorded was if there were signs that the fruit was consumed by animals.

本数据集收录了在一场旨在评估受女贞（Ligustrum lucidum）入侵影响的次生林管理效果田间实验中收集的种子降水数据。实验中设置了六个永久样地，每个样地面积240米×140米（共计3.36公顷，详见相关数据集）。样地以成对方式建立（总共三对），其中一对中的一方被指定为对照组（未采取任何措施），另一方则为处理组（女贞控制及本土树木种植）。实施处理后，建立了288个种子陷阱，每个陷阱均为0.5米×0.5米的蚊帐网格，由木桩悬挂于地面0.30米处。每个样地共部署了48个种子陷阱，每个样地内的四个样带各分配12个种子陷阱。每两周，收集所有落在陷阱上的果实和种子，并在可能的情况下对每个种子进行物种级别的识别。识别工作通过野外指南、从当地野外采集的果实和种子参考集以及当地经验丰富的分类学家支持进行。同时记录了果实是否被动物食用的迹象。
