Gravel Bars Can Be Critical for Biodiversity Conservation: A Case Study on Scaly-sided Merganser in South China

This dataset inlcudes occurrences of Scaly-sided Merganser Mergus squamatus along a 40 km river section of Yuan River, in Central China, for three consecutive winters, and the landscape metrics of river gravel bars from geo-rectified fine resolution (0.6 m) aerial image data. We built habitat suitability models (Generalized Linear Models - GLMs) with the dataset to study the effects of landscape metrics and human disturbance on Scaly-sided Merganser presence probability.
