Acacia cyclops seed counts, South Africa 2004-2023

The data set shows counts of Acacia cyclops seeds in the soil over 20 years (2004-2023) at various sites where biological control agents are active, and where fire events and, or, manual clearing operations were experienced intermittently at some of the sites.Counts were made by taking soil cores which were sorted through a sieve to obtain any seeds that were gathered. Samples were collected repeatedly at some sites and on an ad hoc basis at others with some sites only being sampled once.

该数据集展示了在20年间（2004-2023年）不同地点土壤中刺槐（Acacia cyclops）种子数量的统计，这些地点为生物控制剂活动区域，部分地点还间歇性地经历了火灾事件以及或人工清理作业。种子数量的统计通过采集土壤样本并经筛分处理以获得收集到的种子完成。在一些地点，样本收集是反复进行的，而在其他地点则是根据实际情况进行，部分地点仅进行了一次采样。
