We analysed hydrographic and habitat factors influencing the location of 207 colonies of the grey heron Ardea cinerea in Poland. We compared areas of particular habitats in three buffers around colonies (0-1, 0-10, 0-20km) among eight regions differing in their proportions of studied habitats. We found the highest inter-region dissimilarities in areas covered by water bodies (all scales) and pastures (0-1km). We recognized some indicator habitats characteristic of the majority (water bodies, pastures) or of some (seacoast, inland marshes, urbanized zone) regions. The habitat selectivity index showed that grey herons in buffer 0-1km preferred pastures and water bodies in seven regions and rivers in one subprovince. In buffer 0-10km, forests and urban zones were preferred in seven and five subprovinces, respectively. Our study revealed that both aquatic and non-aquatic habitats are important for the distribution of the grey heron colonies in Poland.
我们分析了影响波兰207个苍鹭（Ardea cinerea）栖息地位置的水文和栖息地因素。我们比较了八个地区（其研究栖息地比例不同）中，围绕栖息地的三个缓冲区域（0 - 1公里、0 - 10公里、0 - 20公里）内特定栖息地的面积。我们发现，水体（所有尺度）和牧场（0 - 1公里）覆盖的区域在不同地区之间差异最大。我们识别出了一些大多数地区（水体、牧场）或某些地区（海岸、内陆沼泽、城市化区域）特有的指示性栖息地。栖息地选择性指数表明，在0 - 1公里缓冲区内，七个地区的苍鹭偏好牧场和水体，一个省份的苍鹭偏好河流。在0 - 10公里缓冲区内，分别有七个和五个省份的苍鹭偏好森林和城市区域。我们的研究表明，水生和非水生生境对波兰苍鹭栖息地的分布都很重要。
