A glacial refugium refers to an area that remained unglaciated during periods of extensive glaciation in the Earth's history, particularly during ice ages. These refugia provided a microenvironment where plants, animals, and other organisms could survive while the surrounding regions were covered by glaciers. The significance of glacial refugia lies in their role as centers of biodiversity.
