Savannas cover at least 40 percent of the global tropics and support a fifth of the world’s population, thus efforts to better understand biodiversity and ecosystem functioning in these systems are essential for climate change mitigation and effective policy formulation. Using our Global Airborne Observatory’s light detection and ranging (LiDAR) technology, the diverse scope of […]
Land use practices over the last century have drastically altered the extent and composition of native Hawaiian forests. One of the exciting projects the Pacific Ridge-to-Reef team at Arizona State University is actively working on is mapping expansive areas of critically important forests at the species level throughout the Hawaiian Islands. These species maps help […]

Understanding ecological systems at a global or regional scale is a complex problem, requiring the integration of a wide variety of different sources and types of data. Asner Lab uses an array of approaches to address this challenge, many of which enhance human-scale analyses with machine intelligence. Guided by project-specific experts, artificial intelligence (A.I.) allows […]
Mapping the biodiversity and functioning of forests and coral reefs is critical to understanding how best to conserve and manage them in a changing world. Advanced Global Airborne Observatory (GAO) mapping technology has reached performance levels required for operational monitoring of forest and reef biodiversity and functional properties from the air. However, spectral-chemical libraries are […]
In 2016, the Global Airborne Observatory mapped much of the Malaysian state of Sabah on the island of Borneo in support of a government-led initiative to establish a large new protected area. This work positioned Asner Lab as a key expert in service to the Malaysian government. Our lab is responsible for identifying the most […]
California is both a global biodiversity hotspot and home to forest ecosystems with the highest aboveground carbon storage per unit of land area on earth. Warming temperatures and changing precipitation patterns threaten California’s forests and their ecosystem services. Asner Lab is working to map patterns of forest species composition, forest functional diversity, and carbon stocks […]

The Global Airborne Observatory (GAO) is mapping forest conditions throughout the Hawaiian Islands, with a special focus on the detection of Metrosideros polymorpha, (also known as Ohi’a), Hawaii’s most important native tree species. The spread of Rapid Ohi’a Death, or ROD, to Ohi’a trees has increased over the years due to a highly aggressive foreign […]
The Global Airborne Observatory (GAO), formerly the Carnegie Airborne Observatory (CAO), is an airborne laboratory developed by Dr. Greg Asner and his team that houses advanced Earth mapping technology. The GAO’s mission is to make scientific discoveries, support conservation, and galvanize action to protect the environment at large geographic scales. Now in its third generation, […]
