maps and images - Locations of the forest conservation projects surveyed in the Chilean Patagonia. We present: the Chilean Patagonia extension (a), the forest conservation projects locations (b), aerial footage acquired during the drone-lidar mapping campaign in September 2023 (c) and ground footage acquired during the same campaign (d).

schematic - Research workflow from data collection, retrieval of GEDI data, description of the reference field tree estimates, point cloud filtering, and generation of products and comparisons of aboveground biomass density (AGBD) estimates at two scales: small-scale operational (existing conservation projects) and at landscape level using all evergreen forests in Aysén’s region.

maps with imagery - Distribution of GEDI high-quality estimates of aboveground biomass density (AGBD) and layout of the canopy height models (CHM) derived from lidar data for the conservation projects in Isla Magdalena (adjacent to the protected National Park) and Lago Verde.
