In his new book “Dead Moose on Isle Royale: Off Trail with the Citizen Scientists of the Wolf-Moose Project,” Jeffery Holden turns decades of volunteer field notes and short essays into an off-trail narrative about the people who sustain one of ecology’s longest-running studies. The Wolf-Moose Project at Isle Royale National Park started with scientists from Purdue University, Durward Allen and L. David Mech, in 1958. Since then, volunteers have collected data through on-the-ground fieldwork and built a six-decade record that reveals how climate, disease and food availability shape population cycles.
