vt wetlands resources data
VT Wetlands Resources - Data
  • National Wetlands Inventory –NWI - Data
  • Source from 1:40,000 CIR to 1:80,000 Black & White Imagery
  • Target Mapping Unit (TMU) from ~1 - 4 or 5 Acres, Based Upon Terrain
  • Tiled on 1:24,000 Quads
  • Show “photointerperable” wetlands
  • Likely To Miss Smaller, Drier (Emergent) or Woodland Wetlands
  • Must Have One or More of the Following Three Attributes:
        • 1) at least periodically, the land supports predominantly hydrophytes
        • 2) the substrate is predominantly undrained hydric soil
        • 3) the substrate is non-soil and is saturated with water or covered by shallow water at some time during the growing season of each year
