Data for the scientific article "Evaluating created wetlands for bird diversity and reproductive success"

The conducted study was done in order to investigate what habitat characteristics could explain breeding wetland bird diversity and reproductive success in created wetlands in Uppland, Sweden. The geographical study units were individual wetlands. For each wetland, the data contains all environmental variables considered and estimated within the study (Landscape forest within 1 km buffer, Urban area within 1km buffer, Neighbouring wetlands within 3 km buffer, Size, area of open islands, area of wooded islands, Water vegetation, Local forest (50 m around shoreline), Flooded area, Year of creation, Inflow of water from other sources, Number of ponds within the wetlands, and whether the wetland is managed), as well as species richness, pair abundance, chick abundance and information on whether species succeeded to reproduce.

Data: data contains bird inventories in created wetlands in Uppland, Sweden.

Data collection description:
Four standardised wetland bird inventories of the 89 created biodiversity wetlands in Sweden took place during the breeding season in 2018: twice during the period when birds were settling or started breeding (14-29 May, "settlement stage"), and twice during the chick-rearing period (18 June - 3 July, "reproductive stage"). The data includes all wetland species except for passerines, and was counting pairs and chicks.

The variables are described in detail in the documentation file.

A file with geographical coordinates for the wetlands, bird_diversity_created_wetlands_coordinates.csv, is included.

A raw data file including migratory species and species information for each visit is available upon request.

本研究旨在探究瑞典乌普兰（Uppland）区域人工营建湿地中，能够解释繁殖期湿地鸟类多样性与繁殖成功率的栖息地特征。本研究的地理观测单元为单个湿地。每份湿地数据均包含研究中考量并估算的全部环境变量：1公里缓冲区范围内的景观森林、1公里缓冲区范围内的城市区域、3公里缓冲区范围内的邻近湿地、湿地面积、开阔岛屿面积、林木岛屿面积、水生植被、岸线周边50米范围内的本地森林、淹水区域、湿地营建年份、外源补水情况、湿地内池塘数量，以及湿地是否接受人工管理；同时涵盖物种丰富度、成对个体数量、雏鸟数量，以及物种是否成功繁殖的相关信息。

数据集说明：本数据集涵盖瑞典乌普兰区域人工营建湿地的鸟类调查结果。

数据收集说明：2018年繁殖季期间，针对瑞典境内89处人工营建的生物多样性湿地开展了四次标准化湿地鸟类调查：两次处于鸟类定居或初始繁殖阶段（5月14日至29日，即“定居期”），另外两次处于育雏阶段（6月18日至7月3日，即“育雏期”）。本次调查覆盖除雀形目（Passerines）之外的全部湿地鸟类，统计对象为成对个体与雏鸟。

变量的详细说明可查阅配套文档文件。

本次数据集附带包含湿地地理坐标的文件bird_diversity_created_wetlands_coordinates.csv。
