Shallow roots make it undesirable for use in soil stabilization.
Honeysuckle has a relatively shallow root system and young plants can be easily hand pulled.
Honeysuckle thickets replace generally deeper rooted native plants, weakening erosion protection on shorelines and hillsides.
Per the US Fish and Wildlife Service "upland invasive plants, such as ... Japanese honeysuckle, reduce the stability of soil, which leads to increased sediment entering streams throughout the watershed."
Early dense foliage blocks light, preventing any ground cover and crowding out native plants
"Honeysuckle out competes and shades out desirable native woodland species, and can form pure, dense thickets totally void of other vegetation." Fact Sheet from The Ohio State University
Open habit leaves bird nests at risk for increased predation.
Fruit has high carbohydrates but is not the high-fat, nutrient-rich food source supplied by native plants that is needed by migrating birds. The Nature Conservancy goes further to state that the berries have no nutritional value to birds.
Native plants supported 35 times more caterpillar biomass (amount by weight) than did alien plants
There are many articles on honeysuckle. Here are some that may be helpful in explaining why we should deal with this plant. The latter two are recommended by staff at Mass Audubon, who along with Maine Audubon and many other local organizations are actively managing this invasive plant on their properties.
