We need to save the trees — but how?

Trees have an incredible ability to absorb carbon — which means protecting, planting and restoring forests are a (relatively) easy way to address global warming. Climate change, however, is making it more complicated. Our forests are (quite literally) going up in smoke, which has far worse consequences than one might expect. In this episode, we explore the role forests play in carbon sequestration, how increasingly intense fires are threatening to turn them into a carbon bomb, and how technology (think drones, satellites and lasers) can assist in our replanting and conservation efforts. The forests have helped us, it’s time to help them. 

Featured in this episode:

• Lola Fatoyinbo-Agueh is a NASA scientist. Working in the biospheric sciences lab, she studies forest ecology and ecosystem structure, using LiDAR to GEDI (more on that later) to map and measure the amount of carbon sequestered by trees.
• Faisal Moola, a biologist. He’s an associate professor at the University of Guelph, and an expert on forest conservation, biodiversity (conducting inventory of areas using drones) as well Indigenous partnerships. He helps us understand what we’ve done in the past to hurt forests, and how we can heal them.
• Amy Cardinal Christianson is a fire research scientist, who specializes in Indigenous fire stewardship and talks about the role of fire in the overall health of trees. She is also a host of a podcast called “Good Fire.”
• Stephen Elliott is the co-founder and research director of the Forest Restoration Research Unit of Chiang Mai University (FORRU-CMU) in Northern Thailand. He works with communities in replanting efforts and has a particular interest in automated forest restoration.
