As Minnesota’s ash trees fall to the invasion of emerald ash borer in the next decade, the forest that borders the 72-mile stretch of the Mississippi River in the Twin Cities metro area is expected to lose one-fifth of its canopy.
Turns out that’s not all bad.
Conservation groups that work in the 54,000-acre Mississippi National River and Recreation Area are using that environmental disaster to thwart a much larger one on the way — climate change.
By replacing ash with other kinds of trees, as well as bushes and other plants, they hope to establish a forest that is more likely to thrive in a future of higher average temperatures and much more erratic precipitation.
Changes in climate and extreme weather are already increasing challenges for forest ecosystems across the world. Many impacts are expected to remain into the future. This means forest managers, conservationists and woodland owners continually need to address climate change to ensure forests can provide a broad array of benefits and services. The USDA Northern Forests Climate Hub and the U.S. Forest Service provide tools to help address this need.
Collaboration between scientists and managers resulted in the publication Forest Adaptation Resources: Climate Change Tools and Approaches for Land Managers. This publication provides a suite of materials enabling land managers to consider the likely effects of climate change and increase the ability of forests to cope with climate change impacts.
