The Watershed Boundary Dataset (WBD) is a comprehensive aggregated collection of hydrologic unit data consistent with the national criteria for delineation and resolution. It defines the areal extent of surface water drainage to a point except in coastal or lake front areas where there could be multiple outlets as stated by the "Federal Standards and Procedures for the National Watershed Boundary Dataset (WBD)" “Standard” (https://pubs.usgs.gov/tm/11/a3/). Watershed boundaries are determined solely upon science-based hydrologic principles, not favoring any administrative boundaries or special projects, nor particular program or agency. This dataset represents the hydrologic unit boundaries to the 12-digit (6th level) for the entire United States. Some areas may also include additional subdivisions representing the 14- and 16-digit hydrologic unit (HU). At a minimum, the HUs are delineated at 1:24,000-scale in the conterminous United States, 1:25,000-scale in Hawaii, Pacific basin and the Caribbean, and 1:63,360-scale in Alaska, meeting the National Map Accuracy Standards (NMAS). Higher resolution boundaries are being developed where partners and data exist and will be incorporated back into the WBD. WBD data are delivered as a dataset of polygons and corresponding lines that define the boundary of the polygon. WBD polygon attributes include hydrologic unit codes (HUC), size (in the form of acres and square kilometers), name, downstream hydrologic unit code, type of watershed, non-contributing areas, and flow modifications. The HUC describes where the unit is in the country and the level of the unit. WBD line attributes contain the highest level of hydrologic unit for each boundary, line source information and flow modifications.

The Connectivity results data are published here: https://bzn-community.maps.arcgis.com/home/item.html?id=e849cae2926d4e8280d04fd595a1b5ffThis layer displays the results of the connectivity sensitivity model, which consists of an overall sensitivity score calculated by summing all scores assigned to each input layer, where higher scores indicate areas with either a larger diversity of layers or higher individual scoring for data present in the area.

The potential connectivity regions data are published here: https://bzn-community.maps.arcgis.com/home/item.html?id=17766fb79653407f8fa7d8fbefcb1120This layer displays generalized pathways that could provide connections between potential wildlife hotspots. They do not represent actual corridors since telemetry and GPS tracking is confidential and not available for this study from Montana Fish, Wildlife, and Parks (FWP).

The wildlife and biodiversity results data are published here: https://bzn-community.maps.arcgis.com/home/item.html?id=60f66fbc129443e4944bb47fe6b9fcc5This layer displays the results of the wildlife and biodiversity sensitivity model, which consists of an overall sensitivity score calculated by summing all scores assigned to each input layer, where higher scores indicate areas with either a larger diversity of layers or higher individual scoring for data present in the area.

Within the models for this plan, the study area acts as the extent of all other layers for analysis and is used to clip input layers.

Model Methods:

Model Methods:1. Extracts layer areas only within the study area.

This data was originally derived from the 2018 Lidar flight of the City of Bozeman. Portions of the data have been updated using data previously maintained by the City of Bozeman GIS department. The data will be in relative alignment to orthorectified photography provided by the City of Bozeman GIS Department.

This document is included in the Gallatin Valley Sensitive Lands Protection Plan as Appendix C Part 2. It describes all data sources included in the current version of the sensitive lands model. Details for each data sources include layer name, the entity that created the data, file type, year published, a brief description of the data and how it was weighted in the model scoring, the attributes that were included in the model and how they were scored, the ArcGIS tools used on the data, and a link to the data download page, and the areas within the study area covered by the data.Note: The links in this document are maintained on an infrequent basis and may not be the most up to date access links. However, the other details provided for each data source should provide enough information to guide users to the correct download page.

The survey was conducted via U.S. Postal Service in November and December 2022 to determine community values regarding sensitive lands. A survey was mailed to a random sample of 3,500 people who own homes in the study area which consisted of Bozeman, Belgrade, Manhattan, Three Forks, and unincorporated Gallatin Valley.
