Bio
Nate Stephenson’s roots in the Sierra Nevada go back five generations, and he has spent much of his life hiking and fishing in the mountains. Over the last two decades, much of his research has focussed on fire ecology, giant sequoia ecology, and restoration of forests that have been altered by prolonged fire exclusion. Nate's ongoing role as director of USGS's Sierra Nevada Global Change Research Program complements his research interests in the climatic controls of forest dynamics and vegetation distribution. He is author of the Sierra Nevada Ecosystem Project chapter on the scientific basis for sequoia grove management.
