Invasive species in the watershed
The flowers appear in early to late spring
Leaves are opposite along the stem, 1.5-2 inches long, and short-stalked.
The bark has distinctive ridges.
The bright red berries are widely spread by birds.
Older stems are usually hollow.
While hand tools can be used to remove younger honeysuckle, chain saws will really help with the older, larger ones.
Where permitted, herbicide is painted on the stumps to prevent regrowth.
Ficaria verna, commonly known as lesser celandine or pilewort, is a low-growing, hairless perennial flowering plant in the buttercup family Ranunculaceae native to Europe and west Asia. It has fleshy dark green, heart-shaped leaves and distinctive flowers with bright yellow, glossy petals. (from Wikipedia)
Lesser celandine thrives along stream banks and in wet areas. It forms dense mats that crowd out spring ephemeral plants before it goes dormant in the summer.

Any introduced species can become invasive; while not on the official list of invasive species, this winter aconite (Eranthis hyemalis) which is in the buttercup family (along with lesser celendine) is problematic in Webster Park. Volunteers have been working on restraining it.
Garlic mustard, Jack-In-the-Bush, or Alliaria petiolata is a non-native understory invasive plant in North America. Garlic mustard sprouts earlier in the spring than most native species. When native species eventually emerge, garlic mustard blocks sunlight making it more difficult for natives to grow. Garlic mustard is particularly damaging because it secretes a compound called sinigrin into the soil that destroys fungal networks that support native species.
