Mission statements of urban forestry-aligned organizations. These organizations do not represent a membership organization for urban forest professionals, as they are either not membership-based or their members are not individual urban forest professionals. Note: These urban forestry organizations fulfill parts of the PIT, especially related to performing an essential service to society, maintaining body of knowledge for urban forestry, and holding professional conferences and networking (1.1, 1.2, 2.1, and 8.4). However, they differ significantly in mission and goals from professional organizations.
