Invasive Plant of the Month: English Ivy

English ivy, also known as Hedera helix, is a plant native to Europe, western Asia, and northern Africa, introduced to Canada in the 1800s as an ornamental plant.

Ontario has 441 known invasive plant species, the most of all provinces. Invasive plants can have severe consequences, including reduced crop yield, increased herbicide use, and reduced forest regeneration.

In natural areas, invasive plants affect species diversity and health by reducing available resources. They can also impact human health, as seen with toxic plants like giant hogweed and wild parsnip.

Recreation areas overrun by invasive plants can become less enjoyable due to increased ticks, dense growth, and reduced wildlife.

Focus on English ivy, an invasive species that can outcompete native plants and harm ecosystems.
