Metro used Terramet, an open source platform created by Sitka Technology Group, to track over $360 million in public investments for natural area acquisitions and stewardship. Terramet consolidated Metro's data from various disconnected databases and files into a centralized system, established consistent workflows, and enabled Metro to easily monitor and report on its portfolio of over 500 properties totaling 13,200 acres. By sharing Terramet as open source software, Metro also helped other organizations more efficiently manage their natural area programs.
