Lindsay uses mapping to better understand how trees influence urban landscapes. She heads data analysis and mapping for the Chicago Region Trees Initiative, and is working on a project to identify tree species across the seven-county Chicago Region. She also works to turn these findings into products - including interactive maps, flyers and presentations - that can be used by forest managers, tree stewards, and the broader public. Lindsay also works to identify where tree plantings could have the biggest impact. This project weighs landscape characteristics, surface temperature, air quality, socio-economic, and health variables to find communities where tree plantings are the highest priority.
