Open source software for collaborative, geographically-enabled urban forest inventory

Urban street trees have myriad proven benefits for communities including providing shade, improving air quality, assisting with stormwater runoff, raising property values, decreasing utility bills, and enhancing the look and feel of communities.

OpenTreeMap is an easy-to-use public inventorying platform that enables individuals, organizations, and governments to collaboratively contribute to an interactive and dynamic map of a community's tree population. The system can be used in a single municipality or cover a broader geographic region with many communities, anywhere in the world.
