Just out: A new geodatabase of fuel treatments across federal lands—published in Scientific Data.
Whether you’re mapping change or assessing risk, TWIG shows when and where treatments happened.

Excited to share our new Fire Ecology study! 🌲🔥 Terrestrial lidar can rapidly and accurately measure crown scorch 20x faster than traditional methods. Our R package, CrownScorchTLS, helps make this method accessible for large-scale forest monitoring.

The Turkeyfeather Fire in the Gila Wilderness, NM has burned as a low-severity fire over about 24,000 acres (so far). This is a continuation of a fire regime that existed for millennia before the 20th century. This 🧵reviews the fire history of the Gila, as my colleagues and I have studied it. 1/18
