Abstract The Montana Wetland and Riparian Framework represents the extent, type, and approximate location of wetlands, riparian areas, and deepwater habitats in Montana. These data delineate the areal extent of wetlands and deepwater habitats as defined by Cowardin et al. (1979) and riparian areas as defined by the U.S. Fish and Wildlife Service (2009). The Montana Wetland and Riparian Framework consists of features that were manually digitized at a scale of 1:4,500 or 1:5,000 from orthorectified digital color-infrared aerial imagery collected during the summers of 2005, 2006, 2009, 2011, and 2013 by the National Agricultural Imagery Program (NAIP). These data are intended for use in publications at a scale of 1:12,000 or smaller. This layer consists of one feature dataset: NHP_Layers. The NHP_Layers feature dataset contains the digital wetland and riparian mapping and consists of the feature class WetRip. This feature class consists of data that have undergone three rounds of internal quality assurance/quality control procedures by the MTNHP.
Purpose To provide current geospatially referenced information on the status, extent, characteristics, and functions of wetlands, riparian areas, and deepwater habitats to promote the understanding and conservation of these resources. These data provide consultants, planners, and resource managers with information on the location and type of wetlands and riparian areas in Montana. These data do not show precise wetland boundaries and should not be compared to boundaries delineated from ground surveys. Wetland polygons are classified in accordance with the Wetlands Classification Standard endorsed by the Federal Geographic Data Committee (FGDC): Cowardin, L.M., V. Carter, F.C. Golet, and E.T. LaRoe. 1979. Classification of Wetlands and Deepwater Habitats of the United States. U.S. Department of the Interior, Fish and Wildlife Service, Washington, DC. FWS/OBS-79/31. Riparian polygons are classified in accordance with the publication U.S. Fish and Wildlife Service, Division of Habitat and Resource Conservation. 2009. A System for Mapping Riparian Areas in the Western United States.
Supplemental Information The Wetland and Riparian Framework layer is one of the 15 Montana Spatial Data Infrastructure Framework layers. The goal of the layer is to have statewide digital wetland and riparian data for Montana. Mapping is completed to the Wetlands Mapping Standard endorsed by the FGDC in 2009 (FGDC-STD-015-2009). As projects are completed, they are submitted to the U.S. Fish and Wildlife Service for inclusion in the National Wetlands Inventory (NWI). Due to a lag time between submittal and availability, this layer may contain data that have been submitted to the NWI but are not yet available for download from the NWI website http://www.fws.gov/wetlands/data/Data-Download.html

To provide current geospatially referenced information on the status, extent, characteristics, and functions of wetlands, riparian areas, and deepwater habitats to promote the understanding and conservation of these resources. These data provide consultants, planners, and resource managers with information on the location and type of wetlands and riparian areas in Montana.
