The type of management prescriptions applied and the level 

 of habitat protection required are dependent on the presence or 

 absence of fish 9pecies (i.e., stream classes: I anadromous, 

 II resident, and III no fish) and channel geomorphic types 

 (e.g., bedrocfc or gravel substrate, channel incision, and 

 channel gradient). Because the presence of fish species and 

 channel types very within and between streams, a range of 

 management options are available to match the specific habitat 

 requirements within a stream reach. Such options may include: 

 variable width no-cut buffer zones ranging from 25 to several 

 100 feet, selective tree harvest within riparian management 

 zones, and combinations of buffer and riparian management 

 zones. This management flexibility provides the most effective 

 protection of fish habitat and enables the harvest of timber in 

 the riparian zone, which is not required for fish habitat. 



Application of riparian guidelines requires planning and 

 coordination among an interdisciplinary team (IDT) of resource 

 managers with expertise in-f isheries, forestry, and hydrology. 

 Minimum standards and management prescriptions developed by the 

 Forest 8ervice for each stream class and channel type (USDA 

 Forest Service 1989). are used as a guide by the IDT to prepare
