The Lake Superior summer water temperatures are increasing more rapidly than regional air temperatures. According to an article in the Ely Timberjay, the surface water temperatures of Lake Superior increased approximately 6 degrees F between 1979 and 2006. This is significantly greater than regional atmospheric warming. How this change will impact biodiversity and the proliferation [...]
The St. Paul Pioneer Press warns that climate change will have a serious impact on the Midwest. Because the Quetico-Superior region is at a crossroads of forest communities: the boreal forest to the north, the broadleaf deciduous forest to the south and the oak savanna to the west, affects of climate change to ecosystems may [...]
A technique to kill invasive aquatic species found in the ballast water of Great Lakes ships made its real-world debut on a vessel traveling from Gary, Indiana to Duluth, Minnesota recently.
Managers of the Superior National Forest are seeking comments on a project that seeks to combat the spread of non-native invasive plants in the Boundary Waters Canoe Area Wilderness.
This summer, Minnesota’s North Shore of Lake Superior will again be the front-line in the battle between agriculture officials and the exotic invasive insect known as the gypsy moth.
University of Minnesota forest ecologist Lee Frelich continues to foresee a transition from forest to savanna taking place at the margins of Minnesota’s north woods. Newly published research suggests that within the century, the climate and ancillary factors will make significant changes to the state’s prairie/forest border.
The Minnesota Department of Natural Resources (DNR) confirmed that spiny waterfleas were discovered by anglers in Burntside Lake near Ely last week. Burntside Lake is a popular entry point into motorless area of the Boundary Waters Canoe Area Wilderness. Water fleas are tiny, but pose threats to lake life. The animals can collect in masses [...]
Minnesota’s first gypsy moth in caterpillar form was found recently in Duluth, confirming that the exotic pest which can defoliate wide swaths of forest is reproducing in Minnesota.
Minnesota’s battle against the gypsy moth is ready to resume. The state’s Department of Agriculture is about to set 23,000 traps for the moths across the eastern border of Minnesota to note where new outbreaks of the invasive pest are occurring.
