Across the United States, invasive plants have taken over much of the land, reducing habitat for wildlife. Many invasive plants are found in this park, like Japanese wineberry. It is a type of shrub that is in the same family as raspberries and blackberries. It is everywhere in the park, and it is easily identified by its red stems that form thick patches on the forest floor. It’s very strong and spreads quickly, replacing the native plants. Without the native plants, there is less habitat area for the animals to live in.
The plant grows broad, bright green leaves on its thorny stems in the spring and summer (Matt McIntosh/NOAA).
