Invasive plant

Amur cork tree is an emerging threat to Wisconsin forests.

Amur cork tree (Phellodendron amurense) is a relatively new invasive plant found in at least four Wisconsin counties. It is classified as Prohibited under Wisconsin’s invasive species law, NR 40. The female cork tree cannot be possessed, transferred, transported or introduced in Wisconsin. We ask that you report this tree to DNR because it is invasive here and in other states and DNR is mounting control efforts before it becomes widespread. DNR works with property owners to achieve this by providing advice, tools and resource opportunities. Continue reading “Amur cork tree is an emerging threat to Wisconsin forests.”

Lesser celandine is an emerging threat to Wisconsin forests – be on the lookout.

Spherical bulbils of lesser celandine form during the spring growing season. Later they drop off and sprout to form new plants.

Lesser celandine (Ranunculus ficaria), also known as fig buttercup, is a ground layer plant and an aggressive invader of forests in North America. So far, it is relatively unknown in Wisconsin but has been found in the southeastern part of the state, especially in moist (mesic and wet-mesic) forests and along river banks.

Lesser celandine is a spring ephemeral that emerges in early spring, develops flowers, dies back by early summer, and remains dormant in underground tubers. During the short growing period the plant produces bulbils which sprout and give rise to new plants. After the round bulbils drop off they are spread by gravity, water, small animals, and like the tubers, transported when soil is moved.
