Summary
A new study published in Earth's Future reveals that California has lost 60% of its coastal sand dunes since the mid-1800s. The research, which combined aerial photos with lidar data, shows that dunes are threatened by urban development and sea level rise. These dunes are critical for protecting coastal communities from flooding and supporting diverse plant and animal life, yet they occupy prime land for human development, making them highly vulnerable.
