Water managers realize the security of their water supplies is tied to the health of distant upland watersheds. One study showed that restoration can increase water supplies in downstream reservoirs by 9 to 16 percent. As climate change intensifies, degraded watersheds will become more and more vulnerable to megafires, likely setting in motion a disastrous positive feedback loop: megafires substantially increase greenhouse gas emissions, which heat the atmosphere and spawn more megafires. For this reason alone, watershed restoration is as urgent as any other kind of climate change remediation.
