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). These data represent wetland and riparian mapping managed by the University of Montana's Ecological Mapping, Monitoring and Analysis (EMMA) Group. Wetland and riparian areas 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, 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 For areas within Montana that do not have updated mapping or modern mapping, please download the NWI Legacy (outdated mapping) data from https://www.fws.gov/program/national-wetlands-inventory/wetlands-data. For more information regarding the different datasets, please refer to the following document https://mtnhp.org/nwi/Wetland_Riparian_Mapping_Status_Info.pdf.

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. (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 two feature datasets: NHP_Layers and NHP_quadStatus.The NHP_Layers feature dataset contains the digital wetland and riparian mapping and consists of the feature class finalprovWetRip. This feature class consists of data that have undergone three rounds of internal quality assurance/quality control procedures by the MTNHP. For data where the Status field is Final, the data have been sent to and approved by the Regional Coordinator of the National Wetlands Inventory of the U.S. Fish and Wildlife Service. For data where the Status field is Provisional, the data have undergone three rounds of internal quality assurance/quality control procedures by the MTNHP but have not been sent to the Regional Coordinator of the National Wetlands Inventory of the U.S. Fish and Wildlife Service. The quadStatus feature dataset contains information about the mapping status of each topographic quad and consists of five feature classes: activeProjectList, finalStatus, historicNWI, noMapping, and provStatus. The activeProjectList feature class consists of quads that are currently being mapped by the MTNHP; the finalStatus feature class consists of quads with mapping that has been approved by the Regional Coordinator of the NWI; the historic NWI feature class consists of quads that were mapped by the U.S. Fish and Wildlife Service using 1980s-era imagery, this includes quads with both digital and non-digital mapping; the noMapping feature class consists of quads for which no mapping exists and no mapping is currently planned; and the provStatus feature class consists of quads with provisional wetland mapping.; abstract: The Montana Wetland and Riparian Framework represents the extent, type, and approximate location of wetlands, riparian areas, and deepwater habitats in Montana.
