Presented live on December 8, 2020, this webinar provides a nuts and bolts review of how the type and number of credits are determined for a conservation bank and how the extent of the service area is determined. For each topic, case studies ranging from the straight-forward to the complicated are shared, along with lessons-learned and emerging trends from the field. Striking the balance between ecological and economic needs is discussed from diverse perspectives. 

It is recommended that participants view Webinar 1: The Market & Regulatory Drivers for Conservation Banking prior to viewing this webinar.
