shagbark hickory saplings he spent months growing from seeds collected 250 miles south of here.
It’s not a species commonly found among the maple, birch, cedar and white pines of northern Michigan. But on this 311-acre property known as Ziibimijwang Farm, few of the newly-planted seedlings are.
“I don’t think it’s been too cold for them yet,” Jansen said as a group of volunteer tree-planters prepared to tuck the saplings into the soil.
Jansen and his colleagues at the Little Traverse Bay Band of Odawa Indians have planted thousands of trees since the tribe purchased the property in 2013, transforming it into a small-scale experiment in girding northern forests against climate change.
Along with the shagbark and silver maple, there’s black walnut commonly found in southern Michigan, sassafras and swamp white oak that typically ranges only as far north as mid-Michigan, and a host of other species — about 30 in all — that Jansen hopes will become the feedstock for a diverse, climate-resilient forest.
“I don’t know which of these species are going to thrive in 50 or 100 years,” said Jansen, the tribe’s conservationist. “So we cast the net broad and try to have something there that creates habitat for wildlife, sources of cultural significance for tribal members and areas to hunt and gather.”
Intermixed with the species foreign to this area, crews on the property — about nine miles southwest of Mackinaw City — have planted more familiar northern species, such as white cedar and paper birch, using seeds drawn from trees at the very southern tip of their range. He hopes the cedar and birch will tolerate warmer conditions, buying time for two species that climatologists have cast as “climate losers” destined to lose footing in Michigan as the earth warms.
