The Undeveloped Habitat Blocks datasets are part of a group of datasets developed and published by the Beginning with Habitat Program (https://www.maine.gov/ifw/fish-wildlife/wildlife/beginning-with-habitat/index.html), a partnership of the Maine Department of Inland Fisheries and Wildlife, Maine Natural Areas Program and other state, federal, and NGO conservation partners in Maine. Maps produced from these data are presented to municipalities and land trusts to encourage open-space planning efforts that include a vision for the preservation of biodiversity. This dataset was created in December 2023 by The Nature Conservancy in Maine in cooperation with the Maine Department of Inland Fisheries and Wildlife, Maine Natural Areas Program, Maine Audubon, Maine Coast Heritage Trust, and Maine Department of Environmental Protection. The primary purpose of the Block Connector Segments is to encourage conservation and development planning that includes a vision of the larger patterns of undeveloped habitat and landscape connectivity.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Block Connector line segments represent stretches of roads that are at least 500 ft. long that separate undeveloped blocks and are the only fragmenting feature of the undeveloped blocks at these locations -- see the undeveloped blocks datasets for details. The are coded for whether they intersect a Beginning with Habitat mapped riparian area and/or are withing 50 feet of a non-open-water wetland as mapped by the National Wetlands Inventory. These connector segments represent stretches of roads that are the least developed stretches of roads between undeveloped blocks of habitat. Roads used in this analysis were a subset of MaineDOT Public Roads (Maine Office of GIS: 2023), E911 Roads Features (Maine Office of GIS: 2023), and NHDOT Roads (New Hampshire Granit 2023). The primary roads dataset utilized was the MDOT Public Roads dataset -- important: Only non-highway roads qualify as connectors (because of the outsized fragmenting nature of divided highways). Therefore, only MDOT roads with a FedFuncClas not equal to 'Interstate' or 'Other Freeway or Expressway' are included as potential connector segments. The E911 roads were used as a supplement to the MDOT public roads - mainly as the best representation of private roads available - only E911 roads with RdClass equal to 'Private', 'Local', or 'Gated' that didn't overlap MDOT public road lines were used in the undeveloped blocks analysis and therefore, this Block Connector Segment product. For more details on the data sources used to define the undeveloped blocks, see the undeveloped block outer boundary and undeveloped block component dataset metadata.</SPAN></P></DIV></DIV></DIV>
