Speakers include Alex Hackman, project manager and restoration specialist from Massachusetts Department of Fish and Game; Robin MacEwan engineering design manager from Stantec; Boyd Kynard, an authority on sea lamprey; Keith Nislow from UMass/US Forest Service on stream ecology; and James Dietrich from Dartmouth College on high-tech survey techniques using drones.
