Invasive species are non-native plants and animals that have the potential to become established in an ecosystem, spread widely, and cause ecological or economic harm or even pose a risk to human health.

WOODY INVASIVES
Invasive trees, shrubs, and woody vines pose a serious threat to natural areas in the Great Lakes region, out-competing native plants and damaging wildlife habitat.

NEW ZEALAND MUD SNAIL
The New Zealand Mud Snail (NZMS) is an invasive aquatic species that now

inhabits some Michigan lakes, rivers, and streams and is expanding
its range. Mud snail populations are increasing in some of our most
valued trout streams across the state. As mud snails take over, they
can reduce the numbers of native macroinvertebrates that fish feed
on. Some fish, including rainbow and brown trout, will eat mud snails.
Because the snail’s shell can’t be digested, the fish receive no
nutrition, which can lead to smaller fish sizes and poor fish health.
Mud snails can be spread by attaching to boating and fishing equipment.
Without natural parasites and with few predators, mud snails are
invading trout streams across the state.
The New Zealand Mud Snail Collaborative strives to improve knowledge on the ecosystem impacts of NZMS, develop strategies to minimize their spread, inform management initiatives, and raise public awareness.
