Aquatic Invaders

Here in Montgomery County, we face a significant challenge posed by hundreds of invasive species. While invasive plants make up a significant portion of these invaders, a large population of invasive animal species negatively impacts our local streams and aquatic environments. These invaders pose a threat to the health and diversity of our precious natural habitats and threaten our delicate ecosystem.

We need your help! Below are five invasive species that currently impact our local ecosystem. Your vigilance and cooperation are crucial in combating this problem. If you spot any of these species, please promptly alert the Department of Environmental Protection. Together, we can protect our native flora and fauna, preserve the ecological balance, and ensure a sustainable future for Montgomery County. Let's safeguard the beauty and biodiversity of our natural environment. Thank you for being an active participant in our conservation efforts.

Why It Matters?

Why does it matter? Invasive species are a significant issue locally, nationally, and globally, and threaten severe consequences for our ecosystems. Montgomery County alone faces threats from over 300 documented invasive plant species, the second highest among Maryland counties. The good news is that we can make a difference!

What Can I Do to Help Stop Invasive Species?

  1. Stop New Introductions:
    • Do not release pets or bait into the wild. 
    • Avoid using non-native plants in your garden. 
    • Clean your boat thoroughly between uses to prevent the transport of invasive species. 
    • Refrain from moving firewood or other plant material, as they can harbor invasive pests. 
  2. Manage Existing Invasive Species:
    • Remove invasive plants from your gardens and yards. 
    • Follow regulations regarding the possession and management of invasive species. 
    • Maintain the overall health of the environment through responsible land management practices. 
  1. Outreach and Reporting:
    • Encourage your local garden center to stock native species, promoting their availability and use. 
    • Collaborate with your community or homeowners association to raise awareness and implement invasive species control measures. 
    • Report any new introductions of invasive species to the appropriate authorities, helping them track and address emerging threats.
