NC's Natural Communities, Part I: Green Swamp

I sometimes wonder what John Lawson saw when he made his way up from "Charles Town" (Charleston) to survey the Carolinas in 1700. To my understanding, he would have been privy to the sight of herds of buffalo (not us) roaming through pillows of golden grasses typical of the longleaf pine savannas that blanketed the region. Rivers and creeks filled with inky water cutting swaths though the soft sand. Untamed clumps of brambles and bushes the natives called Pocosins. Depending on the time of year, fields of Pink Lady Slippers or sunflowers gently rocking in the wind. What did he think when he saw thousands of ducks, geese and majestic swans swirling over wide, shallow lakes, or when he watched a blue heron glide over golden marshes in a silence broken only by the croaking of frogs or the call of the now extinct Carolina Parakeet?

We got a glimpse of a small portion of what he may have seen last week when we visited Green Swamp and again yesterday when we visited Lake Mattamuskeet on the Albemarle-Pamlico Peninsula. And oh what a sight we saw.

Those passing by Green Swamp, located in the southeastern most region of North Carolina, may think they were looking at a scraggly woods in need of development. What looks like overgrown grass grows beneath tall, longleaf pine trees spread generously apart. But the too-small area is what the Nature Conservancy calls "the country’s finest examples of longleaf pine savannas."

Five members of CarolinasAdventures hiking group met in the parking lot off Green Swamp Road and for the next several hours, roamed through the savanna (pun intended) with resident botanist, Kelvin Taylor pointing out flowers, the tangled thickets of the Pocosin, an area he called Ecological succession (the gradual replacement of one community by another) sterile pine tree trees in that area--hence the reason for the succession--and more. I always enjoy these outing. In addition to great company, we always learn something that helps us better appreciate North Carolina's natural communities and the efforts to preserve them. And they're in desperate need of preservation. Poachers and development are slowly eating away at these resources. A multitude of Venus Flytraps and pitcher plants once grew in abundance. Now, we had to search carefully to find a few of the flytraps and a delicate flower that I love, the Grass of Parnassus.


I'm not a botanist so I can't address the importance of the longleaf pine savanna to nature and to North Carolina, but I do know it's part of this state's past, it's a refuge for rare and common species, and it can teach us about plant life and this type of ecosystem. In addition to our little band, a group of students were visiting Green Swamp that day and we had the chance to overhear the instructor point out various parts of the plant life they studied. In doing so, this instructor is helping to preserve Green Swamp for the future. I'm sure John Lawson would have been pleased.

Howell Woods Environmental Learning Center

Howell Woods Environmental Learning Center:
A CarolinasAdventures Learning Experience


East coast members of the CarolinasAdventures hiking group banded together for their first official group hike last weekend. Our destination: Howell Woods Learning Center in Johnston County, NC. An apt name for this obscure treasure, and I couldn't have chosen a more knowledgeable (and amiable) group of people to experience it with.

According to their website and various brochures, Howell Woods is part of Johnston County Community College, which uses the 2,800 plus acres as an outdoor classroom. Fortunately, the college graciously allows the public to use the land for hiking, camping, horseback riding (byoh), bird watching, and hunting. There is a fee for hunting, horseback riding, and camping, but hiking is free.

We rendezvoused at the Learning Center's parking lot shortly after 9:00 A.M. After signing in at the Center as required, we took a few photos of HW's permanent residents--a turkey vulture, an owl, and two red-tailed hawks that can no longer survive in the wild--and then began the hike.

The closest trailhead is located several yards behind the Learning Center, in the direction of the Savannah Pond. Using the trail map we found on the website, we hopped on the Leopold Loop and slowly worked our way into the woods.

Though a bit drab this time of year, sometimes desolate, and what I called "crunchy", Howell Woods is nonetheless fascinating. They have incredibly diverse habitats ranging from arid to soggy (longleaf pine savannah, bottomland hardwood, mixed pine, a variety of wetlands, and more.) We literally walked from a savannah to a cypress swamp, passing a grass and shrub area as we went. Even more incredible, their brochure not only lists the trails, the trail length, and the surface type, it also lists the dominant habitat in that area. Unfortunately, the brochure wasn't the best resource to use to navigate those trails. When we thought we were heading for one area, we ended up in another. One road should have been on one side of the woods, but somehow it intersected with a road in another quadrant. Consequently, we ended up meandering a lot. According to the brochure, there are over twenty-five miles of hiking trails and paved roads in Howell Woods, so we meandered quite a bit.


But we stopped often to explore as we went. We saw birds, large and small, flitting through the tall grasses of the savannah and through trees. Three turkey buzzards circling overhead caught our attention several times. As we hiked, our resident botanist, KT, pointed out various non-flowering plants and trees and encouraged us to identify them. He asked us questions about the habitat we were walking through and how we knew the type (i.e. a savannah or a mixed pine) without sneaking peeks at the brochure to find the answer. We stopped to take pictures of the first spotted wildflower of the season—a violet that should have been named Brittany for all the photos we snapped of it. We also took time to investigate a swamp with clear water, one with stagnant water, and a pond so still we wondered if the shocking shade of putrid green of what turned out to be duckweed hid ground or water.

Howell Woods also has a diverse wildlife population. We saw deer tracks on a number of occasions, tracks that may have belonged to a raccoon, and ruts we decided had been created by a few members of the feral pig population. Wild turkeys, gray squirrels, and waterfowl also reside in the woods. Because Howell Woods states their focus is "Conservation through Education", I was surprised to learn they allow hunting on the premises. I'm having a hard time understanding that, and how monies collected from hunting related activities can, as one brochure states, be "used to fund the ongoing operations benefiting the wildlife/habitat management...." Can someone clarify this for me? (Someone did. Please see comments below.)

The trail system at Howell Woods consists of gravel roads intertwining with boardwalk, sand, and mowed paths. The street signs at the corner of several trails reminded me of those at Dupont Forest in Brevard, where individuals and organizations wrenched back that land as it was being developed into an upscale neighborhood. While the signs do detract from the outdoor experience, they are helpful, especially when used in conjunction with the hybrid satellite photo/trail maps signs, which are posted at several intersections.



As mentioned earlier, we began the hike at the Leopold Loop. From there, we connected to Bartram Trail, Diversity Dr, Longleaf Ln, Wild Turkey Ln, and Hannah Creek Trail, which took us to the far edge of Howell Woods. Somewhere along the line, we stopped at a picnic area. From there, we hiked up Cornell to the BW Wells trail, and then attempted to turn up Thoreau, where a trail full of water hampered our progress.

Note: attempts to circumvent the watery path of Thoreau will result in bushwacking through what KT referred to as wicked prickles, the sting of which feels like thorns until one encounter the thorns. After several minutes of attempting to play the tough hiker, only to find more water and more prickles, we backtracked to BW Wells, and then took Plantation and Howell Dr to the Learning Center (which was, to our surprise, only three quarters of a mile away.)



If you plan to hike through Howell Woods, wear comfortable hiking shoes and pants to protect your legs from bugs and brambles. During bug season, wear a long sleeve shirt or take plenty of bug spray. On second thought, take plenty of bug spray period. Also, watch out for snakes. We encountered a long, grouchy black snake on one of the trails.

Howell Woods is an experience. And because of the sharing of knowledge by the participants on this hike, we not only received lessons in a variety of subjects such as plant life and habitats (pop quizzes and all), but the multiple observations too numerous to mention made by everyone throughout the four-hour hike enhanced this outing experience ten-fold. Don't know individuals familiar with birds, plants, or North Carolina's natural communities? No worries. Howell Woods offers several programs including Plant and Tree ID, Bird Banding, No-Trace Camping, and a course on habitats.
