China’s giant sinkholes are protecting an endangered tree, but they may also be trapping its future

In China, vast sinkholes provide a refuge for the rare Magnolia aromatica trees, buffering them against the harsh realities of climate change. These subterranean havens create stable microclimates that support these endangered species. However, this isolation can limit genetic diversity and hinder the trees’ adaptability to future environmental changes. To ensure their survival, conservation efforts must focus on safeguarding habitats while facilitating gene flow between populations.
