Severe megafires in 2020 and 2021 have significantly harmed sequoia groves in California, hindering their ability to regenerate naturally, two new studies reveal.
Caroline Marshall Reinhart reports for Inside Climate News.
In short:
- Studies found drastically low seedling densities in groves burned by recent megafires, threatening natural regeneration.
- Researchers observed that high-severity fires kill seeds and mature trees, making long-term recovery unlikely without intervention.
- Sequoias store substantial carbon, helping combat climate change, but they struggle to adapt to new climate conditions.
Key quote:
“Our data suggest that sequoia grove areas that were severely impacted by the fires may not have enough reproduction to replace the sequoias lost.”
— David Soderberg, lead author and Ph.D. ecologist at USGS Western Research Center
Why this matters:
Giant sequoias, essential for carbon storage and climate mitigation, are at risk due to increasingly severe wildfires. Without intervention, these iconic trees may not recover, impacting biodiversity and climate resilience.
