Insect-eating plants
including pitcher plants and sundews are common in boreal bog forests. These two plants have two very different methods for trapping
insects. Sundews have sticky threads growing on their leaves, in which insects become entangled. Pitcher plants capture prey in hollow
stalks, where, once trapped, insects can not escape. Other plants have evolved a variety of different strategies for capturing and digesting
prey. All insectivorous plants have an advantage in boreal bogs because they are able to obtain nutrients directly from the insects they
capture.

| Bog sediments become important vegetation records over thousands of years. Grains of pollen from plants in the surrounding area collect in the sediments, and remain identifiable for thousands of years. Sediment samples can be extracted from bogs to determine the history of the vegetation in that area. |
