INVASIVE SPECIES MANAGEMENT
What are invasive species? Invasive species are plants, animals or fungi that are not native and cause harm or are likely to cause harm to the economy, environment, or human health. Not all non-native species are invasive, but the ones that are out-compete native plant species for vital resources like water and sunlight. The loss of native plants to invasive species is extremely detrimental to local ecosystems, wildlife, infrastructure, and more. Invasive species are a serious threat to biodiversity here in Michigan, and across the world. Allegan Conservation District works to fight against invasive species and protect healthy ecosystems in Allegan county.

Hemlock Woolly Adelgid (HWA)

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
​
