Impact/Results
These maps provided a visual for conversation and led to the program expanding and becoming one of the most important programs at American Forest Foundation.
Leadership at AFF needed to present on where we had selected to potentially expand our programming to. Helping the audience better understand why we wanted to expand in the area we had selected was crucial. It gave a very clear vision for our future.
