AGBD: A Global-scale Biomass Dataset

Tracking when trees leaf out or shed leaves reveals how forests respond to climate change, but collecting such data across large areas is costly. SwissPhenoCam repurposes cameras already installed across Switzerland for weather monitoring and tourism, turning existing infrastructure into an ecological observatory. The result is a freely available dataset covering over 5,800 tree-years across more than 20 tree species, documenting species-specific seasonal behaviours along elevation gradients.
