Nature can be a beautiful, calming, and therapeutic thing. Hiking through a forest, running through a field, or even just walking along a beach can be an enjoyable way to spend a day. However, while out on a hike, it’s important to be aware of the plants and animals that inhabit the area. In North America, there are some dangerous plants for humans that can cause severe reactions or can even be deadly if touched or ingested.
Knowing what to look for and how to avoid these plants can help keep you safe while exploring the outdoors. Here is a list of the 10 most dangerous plants that you should be aware of and stay away from while hiking in North America.
What is plant-based danger and why is it important?
Plants can be dangerous in many ways. Some plants have thorns, needles, or spines that can pierce the skin and cause irritation. Some have sticky or resinous sap that can cause irritation or even create a strong bond that will trap you if you come in contact with it. Some plants can cause skin infections or rashes if you come in contact with them. Others have toxic or poisonous parts, such as seeds, leaves, flowers, or roots, which can cause severe allergic reactions, mouth or throat swelling, difficulty breathing, dizziness, vomiting, or even death.
The most important thing to remember is that some plants will cause harm even after you’ve picked them. You can become exposed to dangerous plants even after you’ve removed them from their roots. Seeds, sap, and spores can remain on your clothing, shoes, or even your hands and can cause harm even after you’ve left the scene.
