The Ontario Land Trust Alliance’s (OLTA) Baseline Documentation Report (BDR) Guide was last updated in 2006. A team of four students from Fleming College worked in collaboration with OLTA staff and board to update the BDR Guide to reflect current legislation including the role of the BDR as a monitoring and enforcement tool. This update was completed through undertaking a review of relevant literature, other current BDR templates, feedback from an online survey targeting OLTA members, and valuable input from personal communication with other stakeholders. An important section in the BDR Guide covers methods for updating a BDR and the reasons why an update may be necessary. Natural or human disturbances, CEA amendments, changes in legislation, and advancements in technology can all trigger an update, but what kind of update is required? During this webinar OLTA, Fleming Student Team, and Laura Kucey provided an overview of our updated BDR Guide and explored the different mechanisms and reasons for updating a BDR.
