Toxicodendron radicans AKA Poison ivy


One of the most common plants that we’ve found at our monitoring sites is one that’s useful to know wherever you are: Poison ivy (Toxicodendron radicans). Poison ivy can be hard to identify as it can look very dissimilar from plant to plant or even at different points of the same plant. It is helpful to remember the common cautionary sayings:  


“Leaves of three, let it be!” 


“If it’s a hairy rope, don’t be a dope!” 


Toxicodendron means poison tree. You definitely don’t want to accidentally touch this plant as it gives off an oil called urushiol, which can cause itchiness and puss-filled bumps for many people. Ick! You can get the oils from the plant on your skin from any part of the plant, even in winter or if the plant is dead. Some people have more of a reaction than others to the urushiol, but a sensitivity can develop over time, so it’s best not to touch. If you develop a rash, it is not contagious, but the oils can stay on your clothes or pets for a long time, causing re-exposure to the oils. 


The second part of the name, radicans, means rooting. This is useful to remember as the vine that poison ivy often grows on can become covered in tiny roots that help it cling to and climb trees. Thus, the vine has a hairy or fuzzy appearance.  


The leaves of poison ivy are trifoliate, meaning you will always find 3 leaves together. The plant may have many branches, each with 3 leaves. Be careful to look at multiple parts of the plant as it is possible that damage to the plant may cause you to only see 2 leaves, but most of the plant should have groupings of 3 leaves and never more than 3 leaves. The leaves can vary significantly in shape and color. Leaves may appear green, reddish, shiny, or matte! They may appear as smooth (entire) almond shapes or may have significant toothing (lobing). Poison ivy can grow as ground cover, a bushy plant growing out of the ground, or a hairy vine growing up a tree. Poison ivy has white fruits in the fall and yellow flowers in the summer.

Poison ivy is native to North Carolina. It will grow in floodplain wetlands and swamps, but also grows in drier upland areas. It grows especially well in areas that have been recently disturbed, such as by construction or roadways. It often grows alongside jewelweed (Impatiens capensis), which is another common wetland plant. Jewelweed is sometimes used as a homeopathic remedy for poison ivy that is said to prevent poison ivy reactions. 

Poison ivy is not a true ivy, but it is in the same family as cashews and mangoes. If you develop a severe allergy to poison ivy, you may also be affected by these plants. 


Poison ivy can be confused with a couple other common plants we might see:

Virginia creeper (Parthenocissus quinquefolia) also grows on a vine and can be green or reddish. It has groupings of 5 leaves, but some younger parts of the plant may have only 3 leaves. Check the whole plant and if you see leaves of 5 anywhere on the plant, it is not poison ivy. 

Young box elders (Acer negundo) can also be confused for poison ivy. Box elder is a type of maple that can also have groups of 3 leaves. They grow in wet areas and although they become trees, they start out small and shrubby like poison ivy. It is helpful to look at how the leaves are arranged. Poison ivy has alternate branching, meaning that only one branch will come out of the main stem at any point. Box elders, like all maples, have opposite branching, meaning that 2 branches will depart from the main stem at any point along the stem. If the plant is damaged, there may be some points where you don’t see 2 branches, but if there is any point on the stem where 2 branches come out at the same point, it has opposite branching.

Poison ivy gets a bad reputation, but it has benefits! Its fruits provide food for many animals and its roots help hold soil and prevent erosion, especially in disturbed areas. 


On your next hike, look out for poison ivy in its many forms, so that you’ll be prepared to identify it at our next monitoring events. If you are still unsure, you can practice using iNaturalist on your phone to help you.

Celebrating Our Carolina Wetlands

By rick.savage July 7, 2026
July is Lakes Appreciation Month, an annual celebration led by the North American Lake Management Society (NALMS) to recognize the many ways lakes enrich our lives—from providing drinking water and recreation to supporting wildlife and local economies. It is also an ideal time to recognize one of a lake’s most important, yet often overlooked, partners: lacustrine wetlands. When many people picture a lake, they imagine open water stretching to the horizon. But healthy lakes are much more than open water. Around their shorelines lies a dynamic transition zone where land and water meet. These shallow, vegetated areas are known as lacustrine wetlands, and they are among the most productive ecosystems in the Carolinas. What’s the Difference Between a Lake and a Wetland? Although they are closely connected, lakes and wetlands are not the same. A lake is generally a body of open water deep enough that sunlight cannot always reach the bottom. In contrast, a wetland is defined by the presence of water at or near the surface long enough to support hydric soils and plants adapted to saturated conditions. Lacustrine wetlands occupy the shallow margins of lakes where water levels fluctuate seasonally. Because sunlight reaches the bottom, these areas support an abundance of native aquatic plants such as pickerelweed, arrowhead, bulrushes, and water lilies. Rather than competing with lakes, these wetlands help lakes function as healthy ecosystems. Think of them as the lake’s living shoreline. Nature’s Water Filter Before rainwater reaches a lake, it often flows through wetlands. Along the way, wetland plants slow runoff, trap sediment, absorb excess nutrients, and filter pollutants. This natural treatment system helps improve water clarity and reduce harmful algal blooms. The same wetlands also soften the impacts of floods by temporarily storing stormwater and slowly releasing it after heavy rains. As we have discussed in recent newsletters, healthy wetlands provide one of our most cost-effective defenses against flooding while protecting downstream communities. A Haven for Wildlife Lacustrine wetlands are biodiversity hotspots. Their shallow waters provide spawning and nursery habitat for fish, breeding grounds for amphibians, nesting areas for turtles, and feeding habitat for wading birds. Dragonflies patrol above the vegetation while pollinators visit native flowering plants along the shoreline. Many species spend their entire lives within these wetlands, while others depend on them during critical stages of migration or reproduction. Remove the wetland, and the lake loses much of the biological richness that makes it special. Carolina’s Lake-Associated Wetlands Across North and South Carolina, remarkable lake-associated wetlands demonstrate this close relationship between lakes and wetlands. The majestic cypress-gum swamps surrounding Lake Waccamaw create habitat for rare plants and animals found nowhere else. The extensive shoreline wetlands of Lake Mattamuskeet, the largest natural lake in North Carolina, support hundreds of thousands of migratory waterfowl each winter. Reservoirs such as Jordan Lake , Falls Lake , and Lake Norman also contain valuable coves, embayments, and shallow wetlands that provide wildlife habitat while improving water quality. Closer to home, many neighborhood lakes, farm ponds, and municipal reservoirs include wetland fringes that quietly perform these same ecological services every day. While these wetlands may seem ordinary, together they form an important network that benefits both people and wildlife. Some of our Wetland Treasures such as Merchants Millpond , Robertson Millpond , and Phelps Lake Shoreline are Lacustrine wetlands. Appreciating the Whole Ecosystem As you celebrate Lakes Appreciation Month, take a moment to look beyond the open water. Notice the cattails swaying along the shoreline, the chorus of frogs after sunset, the great blue heron stalking fish in the shallows, or the dragonflies darting among the lilies. Those vibrant edges are not simply the border of a lake—they are an essential part of the ecosystem. Protecting lakes means protecting the wetlands that surround them. Together, they improve water quality, reduce flooding, support biodiversity, and provide countless opportunities for recreation, education, and inspiration. At the Carolina Wetlands Association, we believe that every wetland matters—whether it borders a coastal marsh, a forested swamp, or a favorite Carolina lake. This July, as we celebrate Lakes Appreciation Month, let’s appreciate these remarkable partnerships between lakes and wetlands and continue working to conserve them for future generations. What is your favorite lake with beautiful wetlands? Share your photos and stories with the Carolina Wetlands Association and help us celebrate the wetland treasures that make our Carolina lakes so special. So go out and explore a wetland at your favorite lake or at one of our Wetland Treasures and remember that Carolina Wetlands Association is actively working to protect all wetlands. Your support is always appreciated. Rick Executive Director Carolina Wetlands Association

Hello Wetland Supporters, I hope everyone had a wonderful American Wetlands Month in May and found an opportunity to get outside and explore a wetland. We enjoyed fantastic paddling events at Robertson Millpond Preserve and Lake Mayo, where participants experienced the beauty and importance of these unique ecosystems firsthand. Wetlands have also been in the news recently as the impacts of recent Supreme Court decisions on wetland protections continue to be evaluated. Two recent articles highlight what is at stake: Lisa Sorg in Inside Climate News, Supreme Court’s Limitation on Wetlands Protection Will Make Flooding Worse Jesse Gourevitch and Adam Gold, New Research Shows What’s at Stake When Wetlands Disappea r The central message of both articles is clear: the loss of wetlands leads to increased flooding and rising economic costs for communities. Research cited by Gourevitch and Gold found that wetland loss across the United States has increased residential flood insurance claim payments by an estimated $10.1 billion since 1985 — approximately 9% of all insured riverine flood losses nationwide. The authors also emphasize that policymakers must better recognize the economic value wetlands provide in reducing flood damage to homes and communities. According to the research, the flood-mitigation value of currently unprotected wetlands is estimated at $177 billion nationwide , with North Carolina accounting for approximately $4.6 billion of those benefits . This research reinforces what the Carolina Wetlands Association has long understood: healthy wetlands are essential infrastructure for resilient communities. Through support from the NC Land and Water Fund, Carolina Wetlands Association have received three grants to partner with vulnerable communities to assess flooding concerns and develop restoration plans that incorporate community input, scientific data collection, and hydrologic modeling to identify the most effective wetland restoration strategies. We are also excited to share that we recently received a fourth NC Land and Water Fund grant to begin our first restoration project at Stony Run in Harnett County. Stony Run Walkable Watershed Lumbee Cultural Center Wetland Restoration By working alongside communities and restoring wetland resources, we are helping reduce potential flood damage while also providing additional benefits such as improved water quality, recreation opportunities, shoreline stabilization, environmental education, and greater community resilience. So, the next time you explore a wetland, remember that healthy wetlands mean healthy communities — and your support plays an important role in protecting these valuable ecosystems. Wetlands truly do matter. Best, Rick Savage Executive Director
