Is It Legal to Collect Dogbane in National Parks?

Collecting Regulations

Dogbane (Apocynum cannabinum) is often found in national parks, particularly in North America. While regulations vary by park, most allow the collection of plant materials for non-commercial purposes. For example, the National Park Service (NPS) states that plants can be collected for “personal use, such as making cordage or medicine,” but only if it’s not “for commercial purposes or in quantities that could harm the plant population.” It’s crucial to check with park rangers or visitor centers for specific regulations and restrictions in the park you plan to visit.

Cordage Preparation

The plant fibers obtained from dogbane can be used to create durable cordage, which is an essential survival skill. To prepare the fibers, follow these steps: first, harvest the plant’s stems during the summer months when they are at their strongest, typically between 6-12 inches in length. Next, cut the stems into manageable sections, about 6 inches long, and remove any leaves or debris. Then, soak the sections in water for several hours or even overnight to help break down the lignin, a complex organic compound that makes the fibers more pliable. After soaking, remove any remaining debris and use a hand tool or a mallet to pound the fibers into a pulp. Finally, use a series of twists and turns to create a strong, durable cordage.

Safety Considerations

When collecting dogbane in national parks, be mindful of the plant’s potential toxicity and allergic reactions. The plant’s sap can cause skin irritation and allergic reactions in some individuals, so it’s essential to wear protective clothing and gloves when handling the plant. Additionally, be respectful of the park’s ecosystem and other visitors, and only collect dogbane in areas where it is abundant and not likely to harm the environment.
