Sanctuary Highlights

  • The huckleberry, which turns these Nantucket moorlands into a blaze of scarlet in October
  • Unpaved and usually unmarked sandy cart paths that take you through a prairie-like landscape with Little Bluestem grass, Bayberry, Bearberry, and Lowbush Blueberry.
  • An actively managed landscape that makes use of prescribed fire and mechanical brush cutting to maintain grassland and heathland.
