In class last week, we ventured out the the Presque Isle Bog Walk and Nature Trail. I had never been to (or, been consciously aware of being to) a bog. So, I really had no prior knowledge of what it would be, or what I would observe. The Presque Isle Bog Walk is great because it has so many informative plaques along the path and walkways that contain information about how bogs are formed, their characteristics, and what can be found there.

Bogs grow in cool, moist climates and interestingly prevent the total decay of plant material. Bogs were formed by glaciers which formed shallow lakes. Along these shallow edges, bogs were formed.

Bogs are highly acidic and are low in oxygen beneath the surface. Bogs also lack many nutrients within the soil.

Pictured above, is the pitcher plant. A pitcher plant is unique because it is a carnivorous plant. I had no idea that we had carnivorous plants in our area, until going on this field trip. Pitcher plants have dark red flowers and red-veined, cupped leaves that fill w/ rain water. When insects crawl into the pitcher plants cup, they are digested by enzymes secreted by the plant. Thus, providing the plant with nitrogen.

Above, is my group for MSED 251, Life Science. We explored the trails and made observations along the way. We were also asked to develop a scientific, testable, and important question. This exercise was to help us understand the concept of a scientific, testable question.

Here, shows a plaque and a sign describing and explaining different parts of the bog. The sign on the right talks about the restoration of the wetland that is in process within the Presque Isle Bog Walk.
