SOPE Fall 2020 Nov. 16-20

Originating in China and eastern Asia is the invasive plant wintercreeper. Wintercreeper is one of the most invasive species on the planet and it was brought to the United States in the early 1900s. People first brought it to the United States because it is very beautiful but they didn’t know that it would spread and kill hundreds of plants in the process.

Wintercreeper spreads by people planting it, or birds eating the seed and spreading it by dropping through their feces. It chokes the plants on the surface and crawls up trees blocking sunlight from the tree. It produces red berries in the fall. Wintercreeper grow all year even in the winter. Nothing naturally eats wintercreeper, it creates low biodiversity and affects all life in that area, like birds, insects, reptiles, and in some cases, even humans. 

There are a few ways that you can slow the spread down, or even kill it off for good. Most people don’t realize how bad it is but the ones who do know try their best to kill it off. A few things you could do to slow it down is cut down the vines when you see them, or you could spray certain chemicals on it. Some of the more expensive ways are also very time consuming but they are also more effective.

This month’s blog post was written by Alex and Brady Bogart.

The extent of winter creeper invasion can be nearly 100% cover, as seen in this picture from McDonald County’s Outdoor Classroom. The plant can slowly strangle the trees it climbs, as well as increasing the likelihood of tree damage from winds, ice or snow..
The red berries against the dark green foliage can be very beautiful, but belies the danger this plant can pose to Missouri’s native landscapes.
Wintercreeper can form a nearly impenetrable ground cover, both choking the plants trying to grow and keeping native seeds from being able to make contact with the soil.
The dead vines look ugly for now, but the first step to reducing the impact wintercreeper can have on an area is to eliminate the growth on the trees. This will reduce the impact the vine has on the trees, as well as preventing them from producing more seeds.
