Oaks under threat from invading insects, warming temperatures, disease

The mighty oak may be in trouble in the Great Lakes region – and climate change is largely to blame. A mix of factors is in play, including rising temperatures, more severe and intense rainstorms, increasing susceptibility to plant-eating animals and vulnerability to disease-causing microorganisms, a new study from Michigan Technological University says. “Oaks have evolved a range of adaptations to dry and hot conditions and have an increased range of suitable habitat with climate change,” according to the study in the journal Forests. They were a pioneer species in the Great Lakes region before widespread European settlement, said Amanda Stump, the lead author of the research, and can do well with extreme temperatures. Even so, the study warns, warmer winters, extreme weather events, diseases and extended ranges of herbivores “may still put oaks at risk.”

And that can jeopardize what Stump describes as the important role oaks play in supplying food – acorns – in the fall for bears, turkeys, birds and other wildlife.

Researchers have revealed the Great Lakes’ 10 worst aquatic invasive species, spotlighting the plants and animals that pose the greatest threat to the region’s delicate ecosystems, fisheries and recreational waters. The recent study, published in the Journal of Great Lakes Research, is the first to compare all 188 nonnative species in the lakes with the same methods and pinpoint which are causing the most harm to the region, its authors said. At the top of the list is the zebra mussel. These small but mighty mollusks are believed to have made their way into the Great Lakes in the 1980’s through ballast water in ships from Europe. They can now be found in all five Great Lakes.
