Instructor Information:
Tom Bernthal is the Wetland Monitoring Coordinator for the Wisconsin Department of Natural Resources, responsible for developing wetland assessment and monitoring tools for use in the state. He has an Associate Degree in Land Surveying Technology from Madison Area Technical College and an MS in Water Resources Management from UW-Madison. Some projects he has overseen to date include the development of the Wisconsin Floristic Quality Assessment; statewide mapping of wetlands dominated by reed canary grass; mapping of ephemeral ponds in southeastern Wisconsin and mapping of potentially restorable wetlands in the Milwaukee River Basin, the Rock River Basin and Mead Lake Watershed. He has also helped initiate a series of annual status reports on trackable wetland gains, losses and "acre-neutral" activities across Wisconsin.
Gregg Breese is the Shoreland Program Manager for the Wisconsin Department of Natural Resources, responsible for implementing the statewide shoreland-wetland zoning program. He has a BSE from the UW-Whitewater and holds certificates from the International Association for public participation and project management. He is also a graduate from the Department of Natural Resources Leadership Academy. Some projects he has overseen include small dam removals, county code administrator training, zoning ordinance revisions and publication of Stories From The Shore. He has also helped initiate a series of annual reports on trackable workload and protection levels in zoning including the shoreland stewardship awards.
