Woodburn Plants

The most common finds in the digs at Woodburn High School are of plants. These plants are represented by seeds, leaves and wood. It is clear from the samples gathered, that this was a wetland/bog environment with slow moving water that fluctuated in depth, but at many times was quite shallow (below a meter in depth).

Below is a list of the plants found so far.

Menyanthes trifoliata more likely known as Bog Bean grows in North America. They grow in shallow water like ponds, marshes, and bogs. These plants grow six inches below the water and up to twelve inches above water. Bog beans bloom from May through June, and the color of their flowers is white.

The seeds are the most common item found in the Woodburn deposits. Each year, thousands of seeds are seen and removed from the soils, indicating that the plant was heavily populated in the area during the late Pleistocene.

The Engelmann spruce grows in areas of considerable moisture, usually above 8,400 ft. It’s most often found in high forests. Its scientific name is the Picea Engelmannii. It grows up to 50 meters tall, and its trunk seldom grows over 1 meter thick. The Engelmann Spruce can be killed by spruce beetles which eat the tree. This tree can be found in parts of Canada and in the US.
