Approaching the little Island near this GPS point, notice some trees that are about to fall into the river, along with some trees whose roots are exposed and being undercut by the river. The constant movement of water, both the flow of the river, and the movement up and down during different seasons, causes erosion along the banks of the river.

An undercut tree or bank can provide beneficial habitat for many types of species, because they provide two basic protections that are necessary in the river. First, all undercuts provide needed overhead protection from predators- they provide an area for insects and small fish to hide from birds. Second, they offer protection from strong water currents. Often these undercuts provide shallow pools with very little motion, which can be optimal nesting areas for fish.
