Montana wetland field evaluation : form and instructions / prepared by Jeff Berglund, Morrison-Maierle Environmental Corporation.

Abstract

The HGM method for wetland classification and functional assessment is currently under development for use in Montana. Once "up and running", the HGM method will likely be preferred by the COE relative to all types of projects that potentially affect wetlands and require a Section 404 permit. Work is currently underway to develop regional guidebooks for one subclass each of riverine and depressional hydrogeomorphic groups. These guidebooks may be available as early as midsummer of 1997, but will only apply to one subclass, not all subclasses, of riverine and depressional wetlands, and will likely apply only to the western portion of Montana. Work will continue relative to additional hydrogeomorphic groups, including high elevation slope wetlands, and additional subclasses of riverine and depressional wetlands; however, it is not known when models will be available for all Montana wetlands. MPT Montana Wetland Field Evaluation Form and Instructions July I, Consequently, MDT proposed to revise the 1994 MDT wetland evaluation form to be used in the interim, starting with the 1996 field season. METHODS The 1994 form was distributed to and comments solicited from over members of the Montana Wetland Council that were most likely to be familiar with the form. Comments were solicited from private consultants and numerous agencies/entities including the COE, USFWS, FWP, Environmental
