Parvin State Park Professional Review and Guide
"Where habitats collide, botanical and biological diversity rules. In Parvin State Park, northern and southern ecosystems meet in a preserve that lies just below the Mason-Dixon Line. Here oak-pine upland, swamp hardwood forest, stream flood plain, and Atlantic white cedar bog habitats weave together into a rich woodland tapestry.
It boasts 40 tree types, 61 woody shrubs, 17 ferns and club mosses, plus 200 herbaceous flowering plants. Migrant and nesting birds number at more than 135 species. White-tailed deer, river otter, raccoon, skunk, turtles, salamanders, and nonpoisonous snakes thrive amid dense foliage. The explanation for so much variety packed into such a tight space is a concept biologists call the ecotone. An ecotone marks the boundary between two or more ecosystems or habitats. In an ecotone the species of one habitat freely mix, interact, and compete with those of another for soil moisture and nutrients, light, space, and food. In these transition zones species variety tends to be rich. This 4.6-mile loop walk uses the Parvin Lake Trail, Long Trail, and Thundergust Lake Trail to sample this wealth of life."
