The Pacific Northwest’s ‘Forest Gardens’

 From Science:

For decades, First Nations people in British Columbia knew their ancestral homes—villages forcibly emptied in the late 1800s—were great places to forage for traditional foods like hazelnuts, crabapples, cranberries, and hawthorn. A new study reveals that isolated patches of fruit trees and berry bushes in the region’s hemlock and cedar forests were deliberately planted by Indigenous peoples in and around their settlements more than 150 years ago. It’s one of the first times such “forest gardens” have been identified outside the tropics, and it shows that people were capable of changing forests in long-lasting, productive ways.

“It’s very creative and sort of unique work,” says University of Kansas, Lawrence, plant ecologist Kelly Kindscher, who was not involved in the research. “Many of us know there are historical imprints on the land, but tend to dismiss Native Americans and Aboriginal people globally in terms of their impact.”

Because these wild-looking forest gardens don’t fit conventional Western notions of agriculture, it took a long time for researchers to recognize them as a human-created landscape at all. Many ecologists argued until recently that such islands of biodiversity, seen also in Central and South America’s tropical rainforests, were an accidental and fleeting byproduct of fire, floods, or land clearing. Without constant maintenance, ecologists assumed, the “natural” forest would quickly take over. (Read more.)
