'Lifeboats' Amid the World's Wildfires

The New York Times

Forests have burned in spectacular fashion this year, from California to Colorado, and Portugal to Greece. The fires left scenes of ashen destruction, but they did not wipe out everything. Scattered about the ravaged landscapes were islands of trees, shrubs and grass that survived unharmed.

It’s easy to overlook these remnants, which ecologists call fire refugia. But they can be vital to the long-term well-being of forests. These havens shelter species that are vulnerable to fires. Afterward, they can be starting points for the ecosystem’s regeneration.
