Prevention

Stop the Spread

We have all heard the famous phrase, “An ounce of prevention is worth a pound of cure”. This phrase rings especially true in preventing the introduction and spread of invasive species in our National Parks. There are a variety of simple steps a visitor can take to ensure that they are not transporting invasive species into, around, or out of a park. Listed below are some tips to help prevent the spread of invasive species to our national parks.

  1. Don’t let it loose! Do no further harm by not releasing your pets into the wild or dumping aquariums or bait buckets into waterways. Unused bait should be discarded into trash cans.

  2. Clean, Drain, Dry. Thoroughly rinse your gear and pressure wash your boats, skis, and other recreation vehicles on site. Plants and aquatic organisms can get into any place water can get into. Use hot water if available. Learn how to clean, drain, dry.

  3. Don’t keep invasive species as pets and don't choose invasive species for your landscaping.

  4. Wash your vehicle, especially if you have been driving on unpaved roads or off road. Plant materials can get stuck in your tires and undercarriage. This includes cars, bikes, and ATV's.

  5. Shake out your tent, camp chairs, sleeping bags, and other camp accessories before leaving the campsite to remove any plant or seed materials.

  6. Brush off or wash your pets; if they have been out romping in the parks. Sticky seeds can hitchhike on their fur.

  7. Clean your shoes or boots by knocking dirt and plant materials out of the treads. Consider carrying a boot brush in your car or pack. Rinse the soles if possible.

  8. Wear short gaiters to cover your socks and pant bottoms. This will prevent sticky seeds, such as cheat grass, from getting stuck in your socks.

  9. Don't move firewood. Use local firewood. Do not bring in firewood from outside the immediate area. (Check park websites for specific instructions).

  10. Use weed free feed if possible when using pack animals, such as horses, mules, and cattle, prior to and during, you visit. Contact the park you will be visiting to see if they have a list of local vendors of weed seed free feed.

Graphic of the invasion curve of invasive species
An invasion curve depicts the spread of invasive species over time and the cost of that spread. The longer an infestation goes untreated, the bigger the cost - to the resources as well as monetarily.

The invasion curve is adapted from Invasive Plants and Animals Policy Framework, State of Victoria, Department of Primary Industries, 2010. NPS Graphic/S. Sparhawk.

Early Detection and Rapid Response

Early Detection and Rapid Response (EDRR) means locating invasive species just as they are beginning to invade a particular area and quickly treating the new infestation. This concept is fundamental to effective invasive species management.

Early identification and treatment makes successful control more likely and can save critical funding and resources for the park. EDRR relies upon a strong communication network and the education of visitors, neighbors, and employees about potential invaders.

EDRR is illustrated in the invasion curve (left). If an invasive plant or animal species is not detected and recoved early, expensive and long-term management may be unavoidable.
