Summary

NPR’s Shortwave explores microforests, small human-designed urban forests that boost biodiversity and combat climate change. Producer Rachel Carlson visits a Los Angeles site where scientists Damien Ouellette and Catherine Pacraduni study native plant growth. They use drones and spiderwebs to track wildlife, finding increased species diversity and carbon sequestration compared to nearby control plots.
