New Mexico Rapid Assessment Method (NMRAM) Montane Riverine Wetlands Training
NMRAM Montane Riverine Wetlands
Montane Riverine Wetlands Field Guide Version 2.5 and worksheet packet
The New Mexico Rapid Assessment Method (NMRAM) Montane Riverine Wetlands Field Guide provides updated procedures for conducting a rapid ecological assessment of wetlands in the Montane Riverine Wetland subclass. The Field Guide provides specific protocols and datasheets for evaluating 14 wetland ecological condition metrics using a combination of Geographic Information System (GIS)-based measurements and field surveys. In addition to details on metric measurements, appendices are provided which include the data collection worksheets, a reference guide for taking some metric data, a plant species list with wetland indicator status, the state noxious weed list, photo-point guidelines and a glossary of terms.
Montane riverine wetlands occur along unconfined mountain streams and rivers at elevations between 6,000 and 8,500 ft and in the southern part of the state at elevations as low as 4,800 ft. They generally lie between the subalpine riverine and lowland riverine subclasses. The subclass includes mid-elevation, second- to fourth-order stream segments where valley widths generally exceed 80 m (262 ft) and have a channel width ranging from two to 10 m (6.6–33 ft). Channels have a low degree of confinement from the surrounding landscape and have room for lateral movement, leading to moderate sinuosity. Overbank flooding during peak flows plays a major role in developing and sustaining complex floodplains composed of point bars, terraces, and backwater channels which support the wetland communities. The Montane Riverine Wetland subclass also includes wetlands associated with montane riverine channel reaches exhibiting steeper channel slopes (2-4%), but still within a wide valley as a result of their geomorphic context.
Training Process Overview
View the training videos in the order listed below. You should also download and have available for review the Montane Riverine Wetlands NMRAM Field Guide Version 2.5 and worksheet packet. After watching each video it is recommended you review the relevant section of the Field Guide and practice entering test data into the associated worksheets. The relevant PowerPoint slide set for each video section is also available for download below to review while you are viewing the videos or for later reference.
