Service Description: 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): Federal Geographic Data Committee. 2013. Classification of wetlands and deepwater habitats of the United States. FGDC-STD-004-2013. Second Edition. Wetlands Subcommittee, Federal Geographic Data Committee and U.S. Fish and Wildlife Service, Washington, DC. Riparian polygons are classified in accordance with the publication U.S. Fish and Wildlife Service, Ecological Services Division of Budget and Technical Support Branch of Geospatial Mapping and Technical Support. 2019. A System for Mapping Riparian Areas in the Western United States.

Description: 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. (2013) and riparian areas as defined by the U.S. Fish and Wildlife Service (2019). This is modern mapping completed by Montana Natural Heritage Program's (MTNHP) Wetland and Riparian Mapping Center 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, 2009, 2011, 2013, 2015, 2017, 2019, and 2021 by the National Agricultural Imagery Program (NAIP). These data are intended for use in publications at a scale of 1:12,000 or smaller. These data do not cover the entire state of Montana. For areas within Montana that do not have modern MTNHP mapping, please use the NWI Legacy (outdated mapping) and the NWI Scalable (incomplete mapping) datasets. For more information regarding the different datasets, please refer to the following document http://mtnhp.org/nwi/Wetland_Riparian_Mapping_Status_Info.pdf.
