A new study by scientists at the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR) demonstrates how satellite imagery can track forest recovery after wildfires, offering a faster and cheaper alternative to traditional field assessments. Published earlier this year, the research highlights the role of conservation practices in speeding up regrowth, with protected areas recovering 10% faster than unprotected lands. The study was published in Fire.
The research team analyzed wildfire-affected regions in Northern California and Southern Oregon using data from NASA’s Terra and Aqua satellites (MODIS) and the USGS Landsat mission. By cross-referencing this data with the Protected Areas Database, they assessed recovery rates and fire severity across land management categories.
Key findings revealed that unprotected areas had slower recovery rates (27% after five years) compared to protected areas (37%). Unprotected lands also experienced 25–47% higher burn severity, underscoring the dual benefits of conservation practices in reducing fire damage and aiding regrowth. Evergreen forests showed the most significant recovery advantages under protection.
“This method is a quick, cost-effective way to help managers know where to focus funds to get the maximum benefit,” said lead author Dr. Shima Shams. She emphasized the framework’s potential to guide policy by identifying effective land management strategies.
While satellite analysis cannot replace detailed field assessments, it provides scalable insights for fire and land managers. The NSF NCAR team plans to collaborate with managers to tailor the framework to local needs, helping prioritize conservation efforts and optimize resource allocation for wildfire recovery.
