A recent grant from the U.S. Forest Service's Landscape Scale Restora- tion Program will expand outreach to local units of government in affected areas and provide training to their staff.
Infestations on private and municipal lands in the four-county area are being surveyed by the Ottawa Conservation District, supported by funding from the Great Lakes Restoration Initiative, the Michigan Invasive Species Grant Program and Ottawa County.
To keep information organized and efforts coordinated, all partners use the same software for data collection.
All survey and treatment information is housed in one database managed by the DNR that can be used by partners to inform decision-making and work flow.
When invasive species arrive, they don't come with a set of instructions. Knowing how they will respond to a newly encountered environment,
what they need to survive and whether they develop new behaviors are important considerations in determining how best to control them.
Deborah McCullough, a professor in Michigan State University's depart- ments of Forestry and Entomology, is at the center of a multifaceted effort to understand the hemlock woolly adelgid's life cycle in Michigan, its response to insecticide treatments and the effects of Michigan's winter tem- peratures on its survival.
McCullough and her colleagues have already completed an adelgid risk map, layering hemlock stands identified by satellite imagery over climate data indicating temperatures favorable for adelgid survival.
The map directs survey crews to the most likely places hemlock woolly adelgids might be found. Preliminary findings from treatment studies are communicated with partners and contractors to improve results in the field.
"There are so many parts to managing an infestation - research, funding, partnerships, survey, treatment," McCullough said. "Working together

The hemlock woolly adelgid is an invasive species in Michigan that came from Japan and damages eastern hemlock trees.
