Yet these systems are increasingly vulnerable
And so their condition serves as a visible barometer of the health of the Piedmont Aquifer. Seeps and springs help regulate water levels, maintain cooler temperatures, and sustain streamflow during dry periods— conditions that are all critical for biodiversity. Amphibians such as salamanders and frogs rely on the cool, oxygen-rich conditions of spring-fed habitats, while native plants adapted to moist soils thrive in seep environments. Seep and spring systems can remain hydrated when surrounding landscapes dry out.
These freshwater systems provide refuge for species to survive seasonal stress or extreme weather. When surface waters recede in late summer or during drought, groundwater-fed habitats often remain, giving life to insects, birds, amphibians, and reptiles that depend on reliable water sources.
Yet these systems are increasingly vulnerable
Climate change, urban expansion, and excessive groundwater withdrawals are altering the delicate balance that sustains seeps and springs. Rising temperatures increase evaporation, and changing precipitation patterns marked by more intense storms reduce opportunities for water to slowly infiltrate soil to recharge aquifers. As a result, many seeps and springs are experiencing reduced flows and greater variability. During extreme droughts, they may dry up entirely.

Who lives( and grows) in the springs and seeps of the Reserve?
Many of our favorite animal pals and plants live in and around seeps and springs. Spring Peepers and Spotted Salamanders seek temporary shallow water for mating. Dragonflies live in the mud of forested seeps. And seeps are excellent habitats for the little fellers( microinvertebrates): caddisflies, midges, crawfish— all of whom serve as meals for amphibians. The primary source of water for these resources is underground, so less prone to freezing and that is happy news for amphibians, who depend on seeps and springs for hibernation, as well as mammals who utilize them for water, food and cover. Native plants such as Skunk Cabbage, Sensitive Fern, Green Ash, Sycamore, Tulip Tree, Jack-in-the-Pulpit, and Golden Ragwort thrive in these environments. Tread lightly if you visit these special places as life abounds below and is often hidden.
