Exploring Urban Forestry Modeling and Prioritization Tools
The document discusses Azavea's urban forestry modeling and prioritization toolkit, aimed at identifying key tree planting locations based on various factors and estimating the long-term impacts of trees. Funded by a USDA grant, the toolkit allows users to set adjustable factors to create customized heat maps and calculates the benefits of planting trees. It combines research and open-source tools for improved urban forestry planning and implementation.
