Bark-Code is a handheld LiDAR scanner that uses a tree's unique bark texture as a biometric digital fingerprint, eliminating the need for physical tags. This innovation makes tracking growth and carbon storage affordable and accessible for family forest owners, reducing monitoring costs from $50–$200 to near zero. By enabling smallholders to participate in carbon offset markets, Bark-Code offers a viable alternative to logging, preventing significant CO2 emissions and preserving forest integrity.
