Montana Wetland Mapping (Updated 9/29/2020)
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>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, 2006, 2009, 2011, 2013, 2015 and 2017 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 For areas within Montana that do not have modern MTNHP mapping, please use the NWI Legacy (outdated mapping) and the NWI Scalable (incomplete mapping) datasets.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.</SPAN></P></DIV></DIV></DIV>
