Riley Creek Woods Conservation Area is a beautiful woodland filled with wildflowers, ferns, and sedges.
Each week in May you will see a succession of blooms from wood anemone to Jack in the pulpit and
wild blue phlox.
This area is being threatened by a non-native noxious biennial called garlic mustard. Each plant can
produce thousands of seeds. The plant changes the soil chemistry so that the environment is only
favorable to garlic mustard. If the spread of garlic mustard is not checked, instead of healthy
biodiversity that supports birds and other wildlife, we will end up with a monoculture. Join us to learn
about native wildflowers and to recognize and remove garlic mustard. Bags will be provided. Please
bring your own gardening gloves.
Tour of Wood Rill Scientific and Natural Area
Rescheduled May 26th 10 am -12 pm
From the DNR website:
Wood-Rill SNA preserves an outstanding example of Sugar Maple "Big Woods" forest. This forest type is ranked S2, or imperiled, in the state and is increasingly rare in the developing metro-area.
According to University of Minnesota Forest Ecologist Lee Frelich, individual trees in Wood-Rill range from seedlings to 350 years old, with many trees between 120-180 years old. The oldest trees that Frelich has core-dated are sugar maples. "But none of the trees are as old as the forest," he notes. "Analysis of data from pond sediment indicates that the big woods forest community replaced oak savanna at this site about the year 1300 AD. That tells us that the big woods forest here is roughly 700 years old."
Uplands host a closed-canopy forest of trees over 90 feet tall, the largest with diameters of nearly 3 feet at breast height. Dominant canopy trees included red oak, basswood, sugar maple and white oak. In the more poorly drained lowlands, the dominant trees are red maple, black ash, hackberry, basswood and green ash. Large, downed trees are scattered on the forest floor in various stages of decay. The occasional gap created in the canopy by one of these fallen giants is soon filled by young maples that reach for the light.
