A short drive down a shaded country road leads to South Triangle Pond Conservation Area, 47 acres of quiet woodlands and tranquil pond shores. Here, you’ll be close to one of the most ecologically significant habitats in the world — coastal plain ponds. The preserves lie between South Triangle Pond and Great South Pond and are part of a larger conservation area that protects the high concentration of coastal plain ponds located in this section of central Plymouth. The forested upland is characterized by a hummocky terrain of small hills and steep-sided hollows, formed when sand and gravel were deposited by meltwater from receding glaciers over 14,000 years ago.

From the parking area, you may walk a short distance to the shores of South Triangle Pond, a kettle pond. Trails from the opposite side of the road lead into a forest of eastern white pines, with its understory of huckleberry and low-bush blueberry. Canada mayflower grows in the acidic soil created by the pine needles. Look for the red berries of the wintergreen, which persist through winter. Near the ponds, the pine forest changes into a more open woodland of oak, white pine, and occasional pitch pine. Sweet pepperbush grows tall in the understory and its blooms perfume the air in mid-summer.

Great South Pond, a Coastal Plain Pond, was once Plymouth’s municipal water source. Adjacent to Jenkins Hole lies Barnes-Jenkins Wood Lot. It was once common for small-town New England families to own wood lots from which they harvested wood for cooking and heating.
