In 2010, a Canadian company, CoastEcoTimber began to harvest the standing timber preserved beneath Lake Gatun — the reservoir created when the Panama Canal was built a century ago. In order to provide consumers with assurances of social and ecological responsibility, a chain of custody monitoring was developed to trace shipments of timber from the underwater harvesting, through the milling, manufacturing and distribution processes. Coast Eco Timber hired John to design the documented control system to demonstrate that only Forest Stewardship Council certified Controlled Wood was being exported. John helped put in place transparent set of procedures, including material handling, training and and documentation, that would confirm the source of the the logs.
