Where do the Turtles Go During the Winter?

By Nature

Take a walk on the C&O Canal towpath in the spring or summer and you’re likely to spot turtles sunning themselves on logs in the canal or perhaps along the towpath. Have you ever wondered where those turtles go during the winter months?

Turtles brumate during the winter, similar to hibernation in mammals. Brumation is a semi-dormant winter cool-down that allows turtles to survive when food is scarce and temperatures are much colder. During brumation, turtles can still move but they live off of stored fat and their metabolism slows.

The canal is home to three different types and several species of turtles: the Eastern Snapping Turtle (Chelydra serpentina serpentina), Basking Turtles, and the Eastern Box Turtle (Terrapene carolina carolina).

Eastern snapping turtles are a common find throughout the C&O Canal. As their name suggests, these omnivores have long necks, quick reactions, and are aggressive on land. These large reptiles are almost exclusively aquatic: they occupy the canal and the Potomac River except for land travel during the spring and early summer for mating and nesting. Females lay an average of 50 eggs between April and November. Snapping turtles can be identified by their flat oval brown shell, wide flat heads, bulky limbs, and long alligator-like tail. They weigh between 10 and 35 pounds and are the largest freshwater turtle in Maryland. Eastern snapping turtles dive down to the muddy bottom of the canal and the Potomac River in the winter, remaining alert to light and temperature.

Basking turtles are a frequent sight throughout the canal and in slow-moving or still portions of the river where they can be viewed swimming and sunning themselves on logs or rocks. These turtles rarely ever leave the water except for nesting in the spring and early summer. Eastern Painted Turtles (Chrysemys picta picta) can be identified by their olive-brown to black shells with red markings on the edge, yellow spots on either side of their black head, yellow stripes along the jaw and through the eyes, and yellow or orange belly. These omnivores are just 4.5 to 6 inches long.

Similar species include the non-native Red Eared Slider (Trachemys scripta elegans), and native Northern Red-Bellied Cooter (Pseudemys rubriventris) which are both slightly larger than Painted Turtles. The presence of a red oval-shaped marking behind the eye helps identify Red Eared Sliders from the narrower yellow lines on the Red-Bellied Cooter’s head. Red Eared Sliders are omnivores and are typically 8 to 13 inches long. Red-Bellied Cooter’s are omnivores as juveniles and herbivores as adults, growing 10 to 12.5 inches in length. All basking turtles stay buried in the mud beneath the water during the winter months, occasionally rising to the surface for food or air.

Eastern box turtles are the most terrestrial turtle native to the C&O Canal. They are named for their boxy, high-domed shell and they have the ability to close up their body using a hinge on the shell’s underside. These omnivores can be found throughout the Park, in both forested and open habitats. Like all other turtle species in the C&O Canal, they are most active in the spring and early summer. Box turtles are usually dark brown with gold or orange blotched patterns on the shell, orange scales on the head, neck, and front limbs, and have brown or red eyes, which differ based on the sex of the turtle (typically red for males, yellow-brown for females). They grow to be 4.5 to 6 inches in length, burrowing deep under the soil and leaves to brumate during the winter months.



Pollinators Along the C&O Canal

By Blog, Nature, Photography

June is National Pollinators Month, the perfect time to emphasize the important relationship between pollinators and native plants. One of the things that makes the C&O Canal National Historical Park (NHP) so special is the park’s biodiversity. It is home to more than 1,500 different species of plants, including 118 rare, threatened, and endangered plants. One of the C&O Canal Trust’s more recent initiatives includes raising funds to help protect these rare plants.

How does pollination work? Simple! Pollinators, such as birds, bees, butterflies, and even bats, carry pollen debris to plants, which is then deposited on the stigma of these plants. The plants are then fertilized, which in turn allows them to reproduce, producing fruit, seeds, and more plants. This process is essential to maintaining ecosystems around the world. Pollination allows floral growth, which provides habitat for animals, like insects and birds. Pollinators also contribute to healthy soils and clean water by fostering robust plant communities.

Below we have included several photos of some of the more common pollinators you may see in the park. We encourage you to take note of these important creatures that work hard to help maintain the biodiversity of our beloved C&O Canal! Pollinators’ ecological service is valued at $200 billion each year (USDA, 2020).

Spring Blossoms on the C&O Canal

Bluebells along C&O Near Lock 51 by Cathy Hoyt

Spring is a beautiful time of year to explore the C&O Canal National Historical Park. As nature begins to awaken from its winter slumber, I find my eyes are no longer drawn upward to the tops of the majestic white sycamore trees along the river’s edge, but instead down to the wildflowers at the towpath’s edge. Wildflowers that appear early and have a short bloom time, often referred to as spring ephemerals, are like Mother Nature’s announcement that spring has arrived, and their cyclical appearance reminds me of the rhythms of the earth and the promise of warmer days ahead. 

One of the first spring ephemerals I typically spot along the towpath is dutchman’s breeches (Dicentra cucullaria). The dainty white blossoms of these woodland perennials, which resemble a pair of pantaloons hanging upside down, are my signal to be on the lookout for other wildflowers. Squirrel corn (Dicentra canadensis), in the same family, seems to follow and bloom soon after. It is very similar to dutchman’s breeches, but has heart-shaped blossoms with a pink and sometimes lavender tint to them. The name comes from the resemblance of the plant’s root tubers to corn kernels and the fact that squirrels and other small animals are often responsible for digging up and spreading the roots. 

Bloodroot by Charissa Hipp

Bloodroot (Sanguinaria canadensis) and spring beauty (Claytonia virginica) also appear in the early days of spring along the towpath. Bloodroot flowers only last for a few days; on cold days, the petals stay closed like at night. When the petals are fully open, bloodroot flowers are quite lovely with their solitary flower and the contrast of the golden-orange center against the white petals. The unique lobed leaves of the bloodroot plant often catch my attention long after the blooms have gone away. The name is derived from the red juice in the underground part of the plant’s stem that was used by Native Americans as a dye for baskets, clothing, war paint, and insect repellant. 

Spring Beauty by Charissa Hipp

Spring beauty (Claytonia virginica) is abundant in large patches along the towpath. The petals of this petite woodland perennial are white with very fine pink stripes that vary from light pink to bright pink. Sometimes they’re so faint that the flowers look almost entirely white; other times, the vibrant hot pink is impossible to miss. Spring beauty has blooms that last about a month. 

It’s impossible to talk about spring ephemerals along the C&O Canal without mentioning bluebells (Mertensia virginica). Bluebell season is one of the most anticipated times of year in the Park, waiting for the beautiful blooms that range in color from white to pink to shades of periwinkle. I’m drawn to the bell-shaped, tubular flowers and love discovering bluebell alleys along the towpath when large swaths of them blossom on both sides of the towpath. Once I was standing in such a space, enjoying the beauty of the bluebells when a hummingbird made a brief appearance, attracted to the fragrance of the bluebells.

Trout Lily by Charissa Hipp

Yellow trout lily (Erythronium americanum) reminds me of origami with its unusual and intricate-shaped, nodding blooms. I think the blooms are prettiest when they’re just starting to open and I’ve learned to notice the spotted leaves of the plant long before the blooms even appear. It grows in large patches along the towpath and sometimes I’ll spot a few white trout lilies among the yellow ones. Trout lily tends to bloom a little later in spring and can last well into May. 

These are just a few of the most common spring ephemerals that bloom throughout the C&O Canal National Historical Park. There are many more. Do you have a favorite? Is there a particular one that signals the arrival of spring to you?

Invasive Plants: How You Can Help Prevent Their Spread

By Blog, Nature
One of the most common threats to the natural ecosystems of the C&O Canal National Historical Park are invasive plant species. Invasive species are not native to the area and have a negative impact on the surrounding ecosystem. Many invasive plant species not only outcompete the native plants, but they have little to no native predators, allowing invasives to thrive and spread in the Park. Read More

The Bald Eagle Has Landed

By Nature

The Bald Eagle, considered a sign of strength since the times of the ancient Romans, has been our national symbol since 1782. Fun fact: Benjamin Franklin, in a letter to his daughter in 1784, described the bald eagle as “a bird of bad moral character”. This regal bird has now become an icon symbolizing American strength and fortitude. Read More

Why Fish Need Ladders

By Nature

Fish was a principle food source for early settlers in Maryland and Virginia. As settlements began to creep westward, the demand for fish meant that this valuable food source also needed to move westward from the Chesapeake Bay to its western tributaries. The Great Falls area on the Potomac River posed a challenge since the migrating fish could not go upstream beyond the falls. Industry, canals, and dams also negatively affected this migration.
