Threats to Habitat

Channelization / Ditching

Habitats Affected: Wetlands, water column, soft bottom

Common Sources: Flood control, agriculture, urban and suburban development, forestry

Impacts:

Reduction in wetland habitat.

Loss of wetlands or conversion to uplands reduces system’s ability to filter pollutants and regulate water flows.

Loss of riparian vegetation increases loading of non-point source pollutants.

Filling and channelization reduces fish access to wetlands.

Channelization increases erosion of stream banks and turbidity in the water.

Waters adjacent to channelized streams and ditched wetlands support lower abundance and diversity of fish.
