When Butch Jacobs steps into the woods in search of basket making materials, he does not have a specific type of forest or black ash tree in mind, but he knows it when he sees it. “It’s a unique skill set that cannot necessarily be taught. Some people just have it,” Jacobs said.

Jacobs, a member of the Passamaquoddy Tribe, is one of few remaining basket-tree harvesters in Maine—a longstanding tradition that stretches back to before Europeans arrived on North American shores. Now, the custom faces a threat that may devastate the trees that harvesters like Jacobs seek.

Emerald ash borer, an insect native to Asia, has barreled through ash stands in at least 31 states and three Canadian provinces since it was first documented in Michigan and Ontario in 2002. Black ash, the species basket-tree harvesters target, is especially susceptible to the invasive insect that has already decimated millions of North American ash trees, and will soon arrive in Maine.

That spells trouble for Jacobs and many others, for whom ash trees are of critical cultural and economic significance. The black ash is a central element in several Native American and First Nation traditions, including some tribes’ creation stories.

Despite the importance of black ash to these cultural traditions and Maine’s rural economies, knowledge about the tree’s ecology is limited, and the information that was available was often conflicting.
