Hemlock Woolly Adelgid

ALERT! HWA FOUND IN SLEEPING BEAR DUNES NATIONAL LAKESHORE
Most residents of northern Michigan are familiar with emerald ash borer – an invasive insect that arrived in our state, resulting in the widespread die-off of millions of ash trees. Forests once full of this large, native tree are now stocked with dead snags and state-wide quarantines are still in place preventing the spread of wood material from one place to another. Unfortunately, another invasive species is knocking at our front door, this time targeting a critical habitat species – our hemlocks. The photos emerging from the Appalachian Mountains are stunning. Entire swaths of forest appear to be brown as dense hemlock stands become fatalities to the hemlock woolly adelgid (HWA). Originally from Asia, but now established in the eastern U.S. and moving west, this aphid-like insect can be hard to spot, but they situate themselves at the base of hemlock needles and feed off the trees’ nutrient supply, eventually resulting in mortality. Luckily, unlike with Michigan’s ash trees, this mortality is more gradual – often taking five to ten years. This allows natural resource professionals to work toward saving this crucial hemlock resource. READ MORE>>>ISN WEBSITE LINK

HWA SURVEY

Oak Wilt

Picture
Oak wilt (Ceratocystis fagacearum), first identified in the USA in the early 1940s, is a serious disease affecting many oak species throughout the eastern United States. The fungus that causes oak wilt is likely an exotic species but to date it has not been identified anywhere outside the U.S. The spread and impacts of oak wilt have recently attracted more attention in Michigan due, in part, to an extensive oak resource across much of the state, which comprised 10 percent of the forest volume in the state. Home construction or utility work in woodland areas, and other human activity, can increase the spread of oak wilt. The disease is present throughout much of the oak range in both the Lower Peninsula and Upper Peninsula. It is especially abundant in some localized areas.
