Data supplement for "Bird communities and rehabilitation of the Al Karaana Lagoons in Qatar"

These data accompany the paper (with the same authors) entitled "Bird communities and rehabilitation of the Al Karaana La-goons in Qatar". Briefly, the data describe the number of individuals of each bird species observed at the Al Karaana Lagoons in Qatar before (2015, 2017) and after (2019-2021) restoration work at the lagoon. 2015 data are presence-absence only. Pre-restoration data were collected by independent contractors working for the Qatari government in preparation for the rehabilitation. Post-rehabilitation data were collected by us (primarily by KCC). This updated version removes one species (water rail), as the confidence in the identification was low.

本数据集配套于同作者发表的论文《卡塔尔阿尔卡拉纳潟湖鸟类群落与生态修复》。简要而言，本数据集记录了卡塔尔阿尔卡拉纳潟湖（Al Karaana Lagoons）在潟湖修复工程开展前（2015年、2017年）及开展后（2019年至2021年）观测到的各鸟类物种种群个体数量。其中2015年的数据仅包含物种存在-缺失记录。修复前的数据集由受雇于卡塔尔政府、负责此次修复筹备工作的独立承包商采集。修复后的数据集由我方（主要由KCC）采集。本更新版本移除了1个物种：普通秧鸡（water rail），因其鉴定置信度较低。
