Distribution of waterbirds along the Drugeon river, France

This dataset describes bird observations performed along the Drugeon river, France from 2006 to 2019. 'Carte.jpg' Map of the study area. The box shows the location of the Bannans and the Sainte-Colombe transects. Village locations and the route of the river have been taken from 'BD Carto ', kindly provided for research by the National Geographical Institute, and modified on the basis of field observations. 'Mat sup 1 transects Drugeon synthèse_Zenodo.xlsx' since September 2006, two transects were carried out four times a fortnight,on foot in the early morning. All identified birds, by sight or by ear, were noted with special care to avoid double counting. The two transects are located in the downstream part of the Drugeon valley. The Bannans transect starts from the Drugeon diversion upstream from the Bannans flour mill and runs along the river downstream to the place called Mitray, with a lateral extension to the En Vau-Les-Aigues marsh located partly in the La Rivière-Drugeon village. This transect is approximately 5.4 km long, of which 1.4 km follow the river. It sampled the bird population of the river, the marshes more or less wooded with willows, birches and a few spruces, and the neighboring meadows and pastures. The flour mill dam provides a 3660 square meter body of water that is not flushed out because it is attached to a dwelling house. This is the only non-huntable wetland area along the two transects. The Sainte-Colombe transect starts from the village, crosses the mesophilic and then wet meadows to reach almost the downstream end of the Bannans transect. It then runs along the river in its undisturbed part to the Chaffois mill. The return to the village is via an agricultural path that crosses mesophilic and humid meadows, a marsh and a small wood of poplar and spruce trees. This transect is 8.6 km long including 2 km along the river. A U-shaped pond carved out of a marsh provides an open water surface of approximately 3400 square meters. It was also prospected during the transect. 'Mat sup 2 données brutes descente du Drugeon.xlsx' covers the censuses along the course of the Drugeon river from 2014 to 2019. Birds were recorded during a course carried out on foot along the river on a bank from the Dompierre bridge located between Vaux-et-Chantegrue and Bonnevaux villages to the Pont Rouge bridge next to Vuillecin village (29,2 km representing almost the entire course of the Drugeon river). Each year, the census was taken in sections during the second half of October, an average of one to one and a half months after the opening of the hunting season. Each waterbird observed was precisely located on a map and then plotted on Google Earth. Using Géoportail and field surveys, a precise description of the watercourse has been carried out on the whole of the prospected area: environment bordering each bank (forest, wooded marsh, herbaceous marsh, meadow, village), vegetation on each bank (continuous willow, megaphorbiaie with scattered willows, pure megaphorbiaie, phragmitaie, short herbaceous vegetation), width of the river, slope of the watercourse, status with respect to hunting (huntable zone, zone not huntable because located less than 150 m from homes and hunting reserve). The figures of the following three files are computed from the two files above: Mat sup 1 and Mat sup 2: 'Mat sup 3 Down river walk.zip' Distribution and abundance 2014-2019 of the main waterbird species along the Drugeon river 'Mat sup 4 Hunting season onset.zip' Abundance of the Anatidae species on the Bannans and Sainte-Colombe transects according to the opening date of waterbird hunting 'Mat sup 5 Bannans transect.zip' Abundance of the Anatidae species on the Bannans and Sainte-Colombe transects according to the opening date of waterbird hunting 'TransectsDomi.kml' a kml file locating the Bannans and Sainte-Colombe transects (polylines).本数据集记录了2006年至2019年间法国迪尔热翁河（Drugeon river）沿岸的鸟类观测情况。'Carte.jpg'为研究区域地图，图中矩形框标注了邦南（Bannans）与圣科隆布（Sainte-Colombe）样线（transect）的位置。村落点位与河道数据来源于法国国家地理研究院（National Geographical Institute）无偿提供的'BD Carto'地理数据集，并结合野外实地观测进行了修正。 'Mat sup 1 transects Drugeon synthèse_Zenodo.xlsx'：自2006年9月起，研究人员于每日清晨徒步开展两条样线的调查工作，每两周重复四次。调查中对通过肉眼观测或鸣听识别的所有鸟类均进行细致记录，以避免重复计数。两条样线均位于迪尔热翁河谷下游区域。 邦南样线起点为邦南面粉厂上游的迪尔热翁河分流处，沿河道顺流而下至米特雷（Mitray）点位，其侧向延伸至部分位于拉里维耶尔-迪尔热翁村的昂沃-莱艾格（En Vau-Les-Aigues）沼泽。该样线全长约5.4千米，其中1.4千米沿河道布设，调查对象涵盖河道鸟类、以柳树、桦木及少量云杉为主的多树沼泽，以及邻近的草甸与牧场。面粉厂水坝形成了一处面积达3660平方米的滞水水域（未进行水体交换，因其依附于住宅建筑），为两条样线沿线唯一的非狩猎型湿地。 圣科隆布样线起点为村落，途经中湿草甸与湿草甸，几乎延伸至邦南样线的下游端点，随后沿河道未受干扰的河段顺流至沙夫瓦磨坊（Chaffois mill）。返程则沿农田小径穿过中湿草甸、沼泽以及一片由杨树与云杉组成的小型林地。该样线全长8.6千米，其中2千米沿河道布设。一处由沼泽改造而成的U形池塘提供了约3400平方米的开阔水面，调查期间也对该区域进行了踏勘。 'Mat sup 2 données brutes descente du Drugeon.xlsx'：涵盖了2014年至2019年间迪尔热翁河沿岸的鸟类普查数据。普查人员沿河道单侧河岸徒步开展调查，起点为位于沃-尚特格吕（Vaux-et-Chantegrue）与邦沃（Bonnevaux）两村之间的当皮埃尔桥（Dompierre bridge），终点为毗邻维耶桑村（Vuillecin）的红桥（Pont Rouge bridge），全程29.2千米，几乎覆盖迪尔热翁河全段。每年普查均于10月下旬分区段开展，即水鸟狩猎季开启后的1至1.5个月左右。每一只观测到的水鸟均会在地图上精确定位，随后导入谷歌地球（Google Earth）进行标注。 研究人员借助Géoportail平台与野外实地踏勘，对普查区域内的河道进行了全面精细化描述：包括两岸毗邻环境（森林、树沼、草本沼泽、草甸、村落）、两岸植被（连续柳林、散生柳树的大型草本群落、纯大型草本群落、芦苇群落、低矮草本植被）、河道宽度、河道坡度，以及狩猎管制状态（可狩猎区域、距住宅不足150米的非狩猎区域、狩猎保护区）。 以下三个衍生数据集均基于上述两个基础文件（Mat sup 1与Mat sup 2）计算得到： 1. 'Mat sup 3 Down river walk.zip'：2014-2019年迪尔热翁河沿岸主要水鸟物种的分布与丰度数据； 2. 'Mat sup 4 Hunting season onset.zip'：基于水鸟狩猎季开启日期统计的邦南与圣科隆布样线鸭科（Anatidae）物种丰度数据； 3. 'Mat sup 5 Bannans transect.zip'：基于水鸟狩猎季开启日期统计的邦南与圣科隆布样线鸭科物种丰度数据； 4. 'TransectsDomi.kml'：用于标注邦南与圣科隆布样线（折线）的KML文件。
