INVASIVE SPECIES MANAGEMENT

The Allegan Conservation District is a proud member of the West Michigan Cooperative Invasive Species Management Area (WMCISMA) which provides assistance identifying, surveying, and treating populations of invasive species across 7 counties (Allegan, Kent, Mecosta, Montcalm, Muskegon, Newaygo, Oceana, Ottawa).

Identification and survey assistance is available free of charge, and treatment of invasive species is done for a small fee. Invasive species treatment through WMCISMA is eligible for a cost-share with the Allegan Conservation District.

Contact the WMCISMA for more information on their services, help managing invasive species on your property, or how to get involved in our cost-share program!

Hemlock Woolly Adelgid (HWA) Surveys

IMG-3154 (1).jpg

HWA is an invasive insect native to Japan. It extracts sap from hemlock trees, weakening needles, shoots, and branches. Over time, tree growth slows, and without treatment, infested trees die within 4-10 years. Hemlocks are some of the oldest living trees in Michigan, providing important habitat and winter cover for many species.

HWA can be identified by:

  • White, cottony masses about 1/4 the size of cotton swab attached to the twigs, at the base of needles on underside of branches

  • Needle loss and branch die back, no new growth

  • Gray-tinted foliage

 

Do you have hemlock trees on your property? The Allegan Conservation District offers surveys to Allegan County landowners to assess hemlock tree health, check HWA status, and tag trees for future treatment. Once property is surveyed, landowners are eligible for treatment through our cost-share program.

 

Please fill out the form below to request an HWA survey of your property. Email completed forms to Emily Brown at emily.brown@macd.org.
