🐛Introduced earthworms are dramatically changing the nutrient composition of forest soils, impacting native plant communities.
🌿Giant hogweed, an invasive plant, poses a threat to human health due to its sap, which can cause severe skin burns upon contact.
What are the impacts of introduced earthworms on forests?
—Introduced earthworms are altering soil composition and nutrient availability, affecting the growth of native plants and potentially disrupting forest ecosystems.
Why is giant hogweed dangerous?
—Giant hogweed's sap contains compounds that, when exposed to sunlight, can cause severe burns and damage to human skin. It also crowds out native plant species.
