One of the distinct ecosystems is the Riverine Forest. These are found on the lower flood plains along the rivers edge. The main species found here is one of the deciduous species; the Balsam Poplar. These trees like a high volume of moisture and are able to tolerate flooding. They are distinguishable by their thick, gnarly bark and their larger, pointed leaves.
