Global Tree Density
As part of a team of researchers at Yale School of Forestry and Environmental Studies I helped assemble over 400,000 plots of tree density around the world. We combined these ground based measurements with remotely sensed layers of the earth's surface to produce a spatially-explicit map of tree density, as well as an estimate for the total number of trees of earth - over 3 trillion! This work supported conservation and reforestation efforts by Plant for the Planet and was done in led by Dr. Thomas Crowther in collaboration with Henry Glick, Dr. Kristofer Covery, Charlie Bettigole, Dr. Daniel Maynard, and many others!

Ecoregions
Ecoregions have long been considered a foundational unit of environmental research and management. However, until recently we had no emperical evidence that, at global scales, they were accurate predictors of species diversity. In a series of papers we look at the strength of these groupings and what the biotic and abiotic drivers of species clustering may be. This project has been an amazing collaborative effort with a great group of PhD students and Post-Docs from Stanford.
