This report explores how software technology could be used to support the long term systematic monitoring of urban trees by trained professionals, student interns and volunteers; assist with tree planting and maintenance data processes; and enable data to be organized and shared between researchers and practitioners. Interviews with researchers and forestry practitioners evaluated how various individuals would interact with a software tool designed for long-term urban forestry monitoring, then a list of related system requirements for an ideal software monitoring system was created. Using that list of requirements, an evaluation of eleven existing software platforms in three general categories (proprietary forestry software, proprietary non-forestry specific software, and free and open source software) was completed and options listed for expanding the software to meet the system requirements. The report concludes with a series of recommendations regarding cost and tech support, establishing an open data standard, creating a central data repository, and balancing collaboration andleadership.
