The stages in bog development are divided up by a series of circles that can be easily identified as you look out over a bog. In the middle of the bog is an area of open water. Around that is a mat of Sphagnum moss and other plants that are so thick in spots a person can walk on top of the mat without falling into the water. The whole mat moves up and down. The outside circle is made up of tall shrubs that give way to a forest of tamaracks or other trees.
Bogs have very little decomposition of organic matter creating a very acidic soil.
In this nutrient-poor soil, some plants have adapted by becoming carnivorous. Examples include Venus flytraps and pitcher plants. These plants trap insects to supplement their photosynthetic diets.
