Peatlands 101 - Florida's Hidden Climate Superpower

In this episode, we're joined by two leading scientists from The Nature Conservancy to explore one of the most under-recognized natural climate solutions on the planet: peatlands.

Catherine Fitzgerald, global lead for peatlands at The Nature Conservancy, brings a wealth of expertise in unlocking equitable and durable opportunities to conserve and restore peatlands worldwide. With a Master of Environmental Management from Duke University and years of experience as a professional wetland scientist, Catherine leads TNC's global work to protect these ecosystems for climate, water, and people.

Morgan Higman, climate strategy director for The Nature Conservancy in Florida, focuses on accelerating clean energy and natural climate solutions across the state. Her doctoral research in public administration and policy at Florida State University's Askew School was supported by the National Science Foundation, the U.S. Department of Energy and the Environmental Research and Education Foundation.

Peatlands are ancient wetlands made up of layers of partially decayed plant matter that have accumulated over thousands of years. Bogs, swamps, and fens all fall into this category. Though they cover just 3% of the planet, peatlands store one-third of the world's soil carbon and 10% of its freshwater. That's more carbon than all the world's forests combined. Healthy peatlands filter water, buffer communities against floods and drought, reduce wildfire risk, and support unique plant and animal species. When drained or disturbed, they flip from carbon sinks to carbon sources, releasing stored greenhouse gases and compounding the very climate risks they once helped prevent.

Catherine and Morgan walk us through why Florida is a standout state for peatland restoration. A 2025 TNC spatial analysis identified Florida as having some of the greatest restoration potential in the Southeast, with the St. Johns River Water Management District emerging as a priority area. With support from VoLo Foundation, TNC is conducting a deep-dive assessment of high-opportunity sites across the region, bringing together water management districts, local landowners, scientists, and community partners to identify lighthouse projects that can catalyze action at scale.

This work is part of TNC's broader global peatland strategy, with active initiatives across more than a dozen countries and states, including North Carolina, Minnesota, Colombia, and Mongolia. In North Carolina alone, TNC was recently awarded a $200 million EPA grant to restore and protect approximately 43,000 acres of peatlands. Florida's program builds directly on those decades of groundwork, with the goal of creating a replicable framework for the entire Southeast.
