The Baltimore County Forest Sustainability Project used the Montréal Process Criteria and Indicators (MPC&I) as a tool for engaging stakeholders and developing a Forest Sustainability Strategy for the County. The MPC&I allowed participants with divergent points of view to develop a common understanding of local forest issues, identify those issues requiring additional study, and agree on necessary actions to ensure the long-term health and vitality of Baltimore County’s diverse forest resources. Four years after it began, the Forest Sustainability Project continues to engage the original participants as well as a widening circle of stakeholders working cooperatively to maintain, preserve, and enhance the forests of Baltimore County.
