Metric Guidance

Metric Guidance ID	Description	Used on Work Elements
218	Enter the quantity of rootwad structures used for stabilization of the streambank or channel. (Note: If rootwad structures are not used, enter a "0" for the value of the metric.) - Stumps with roots attached (root wads): Placement of a stump with roots attached into the stream or on a bank. Root wads are a type of large woody debris. (Note: if rootwads are fastened to multiple pieces of wood, select "logjam".) - Stabilization: The structure serves as a means to stabilize sediment in the stream or on the bank of the stream.	29

29. Increase Aquatic and/or Floodplain Complexity	Active	This work element is intended for the placement of natural materials in the water or on the floodplain to create habitat features or improve channel morphology. Actions include placement of large woody debris (LWD), constructed riffle features, boulder placements, and beaver dam analogs (BDAs). It also includes placing gravel to improve complexity by creating pools or fish spawning habitat. Complexity structures are typically used in stream reaches with limited natural tendencies to foster development of, or ability to maintain, natural habitat features. For example, structures are often placed to improve habitat variability for fish in otherwise uniform flow conditions. These actions can have the objectives of creating and/or maintaining scour pools, influencing channel sinuosity and hydraulic complexity, recruiting and retaining wood and gravel, sorting of gravels, and supporting hydrologic connectivity with the floodplain. Design review should be at 80% completion before contracting to help assure implementation and expenditure of contracted funds. When this WE is used, the contract must also include 175. Produce Design . If structures are being added to resolve a fish passage barrier, use 184. Install Fish Passage Structure . If maintaining an existing structure, use 186. Operate and Maintain Habitat/Passage/Structure . If work involves only plantings, use 47. Plant Vegetation . If other methods are used to control erosion in the riparian and upland zones, use 55. Erosion and Sedimentation Control . This work element should not be used for bank stabilization unless it is part of a larger habitat or complexity action.	2011		218	Enter the quantity of rootwad structures used for stabilization of the streambank or channel.
