Montana Natural Heritage Program (MTNHP) 20130201 vector digital data Helena, Montana Montana State Library ftp://ftp.gis.mt.gov/WetlandsFramework/ http://gisservice.mt.gov/ArcGIS/rest/services/MSDI_Framework/WetlandsRiparian/MapServer 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, and 2011 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 quadStatus. The NHP_Layers feature dataset contains the digital wetland and riparian mapping and consists of two feature classes: finalWetRip and provWetRip. The feature class, finalWetRip, consists of data that have undergone three rounds of internal quality assurance/quality control procedures by the MTNHP. These data have been sent to and approved by the Regional Coordinator of the National Wetlands Inventory of the U.S. Fish and Wildlife Service and are considered final. The feature class, provWetRip, consists of data that have undergone three rounds of internal quality assurance/quality control procedures by the MTNHP. These data may or may not have been sent to and approved by the Regional Coordinator of the National Wetlands Inventory of the U.S. Fish and Wildlife Service and are considered provisional. 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 that have been approved and incorporated into 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, these include 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 that have been mapped by the MTNHP. 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. The Wetland and Riparian Framework layer is one of the 14 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/DataDownload.html 20130201 publication date In work Quarterly -116.451402 -103.558465 49.180617 44.115422 ISO 19115 Topic Category biota environment inlandWaters Wetlands Deepwater habitats Hydrography Surface water Swamps, marshes, fens, ponds Riparian NWI Montana Spatial Data Infrastructure MSDI Wetland and Riparian Framework Montana None. Acknowledgement of the Montana Natural Heritage Program is appreciated in products derived from these data. Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a different manner than that used in this layer. There is no attempt, in either the design or products of this inventory, to define the limits of proprietary jurisdiction of any federal, state, or local government or to establish the geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities involving modifications within or adjacent to wetland areas should seek the advice of appropriate federal, state, or local agencies concerning specified agency regulatory programs and proprietary jurisdictions that may affect such activities. Information in this data layer is not intended to be used as a precise locator of wetland boundaries, for site specific planning or management, or for regulatory purposes. Proper use of wetland and riparian mapping requires knowledge of the inherent limitations of this mapping. It is suggested that users also consult other information to aid in wetland detection, such as U.S. Department of Agriculture soil survey reports and other wetland maps that may have been produced by state and local governments.

Helena MT 59620-1800 USA 406-444-0915 knewlon@mt.gov 8-5 M-F The Wetland and Riparian Framework was created by the Montana Natural Heritage Program. Montana Natural Heritage Program 2013 The minimum mapping unit is 0.1 acres for wetland polygons and 0.5 acres for riparian polygons, although polygons smaller in size can be mapped if interpretable and mappable. Linear features such as streams, canals, or ditches are mapped if they are 15 feet (3 meters) or greater in width at a mapping scale of 1:4,500. The horizontal accuracy minimum requirement is commensurate with the base imagery scale. The base imagery scale for this layer is 1:12,000. The minimum horizontal accuracy requirement is 5 meters. The Wetland and Riparian Framework is either complete, in progress, or scheduled to be mapped for approximately 75% of Montana. This data set represents the extent of wetlands, riparian areas and deepwater habitats that can be determined with the use of remotely sensed data and within the timeframe for which the maps were produced. The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the amount and quality of the collateral data, and the amount of ground truth verification work conducted. Error is inherent in the interpretation of aerial imagery, thus detailed on-the-ground inspection of any particular site may result in revision of the mapped boundaries or classification. Wetlands or other mapped features may have changed since the date of the imagery and/or field work. Differences may exist in polygon boundaries or classifications between the information depicted on the map and the actual conditions on the ground. Montana Natural Heritage Program 20130201 20130201 Mapping is completed by individual project area. Mapping project areas are largely determined by the project funder. Once a project area is selected, a shapefile of the project boundary is sent to the NWI Regional Coordinator and the USGS Wisconsin Internet Mapping Center. A file geodatabase is sent by the USGS containing the empty wetland and riparian feature class. Wetland and riparian mapping is created in this feature class. Image analysts with MTNHP use 1-meter resolution color-infrared aerial ortho-rectified imagery to develop photo signatures and interpret wetlands and riparian areas. This imagery serves as the base imagery from which wetland and riparian data are produced. Wetland and riparian mapping data are produced through on-screen digitizing performed at a mapping scale of 1:4,500. Ancillary data layers such as multiple imagery years, topographic maps, digital elevation models, and hydrography data are used to improve mapping accuracy. Wetland polygons are classified according to the FGDC Wetlands Mapping Standard (2009), which is based upon the Wetlands and Deepwater Habitats of the United States (Cowardin et al. 1979). Riparian polygons are classified according to the USFWS A System for Mapping Riparian Areas in the Western United States (2009). Mapping is completed for U.S. Geological Survey 1:24,000 quadrangles. Once mapping is complete for an individual quadrangle, the image analyst runs several verification checks to fix any errors in polygon attribution. Any topology errors are also fixed to eliminate overlapping polygons. Three rounds of internal quality assurance/quality control (QA/QC) procedures are conducted for each mapped quadrangle once the above steps are completed. The first round of QA/QC is conducted by an image analyst with MTNHP who did not complete the mapping. The image analyst who mapped the quadrangle makes any necessary corrections based on comments made during the first round of QA/QC. The second round of QA/QC is completed by a third image analyst who reviews the comments and corrections resulting from the first round of QA/QC. A third round of QA/QC is completed by a MTNHP project manager. Once final edits are complete, verification checks are completed a second time. Data are then incorporated into the provisional wetland and riparian layer (provWetRip). Data are also sent to the NWI Regional Coordinator for review and approval. Once approved, data are added to the final wetland and riparian layer (finalWetRip). Mapping within the final wetland and riparian layer is edge-matched with surrounding areas to produce a seamless layer. 20130201 Robin Lium Montana Natural Heritage Program mailing address
