What happens if you plant an invasive species?

Habitat loss and invasive plants are the leading cause of native biodiversity loss. Invasive plant species spread quickly and can displace native plants, prevent native plant growth, and create monocultures. Invasive plants cause biological pollution by reducing plant species diversity.

What are some invasive species in the wetlands?

How can invasive species be eradicated?

Chemical control includes the use of pesticides, herbicides, fungicides, and insecticides. Cultural control includes manipulation of habits to increase mortality of invasives or reduce it’s its rate of damage (selection of pest-resistant crops, winter cover crops, changing planting dates).
