Dogs raise awareness in National Parks about aquatic invasive species





Grand Teton and Yellowstone national parks, in partnership with Working Dogs for Conservation, will host trained dogs that will raise awareness about aquatic invasive species. Scent dog Tobias will be in Yellowstone July 19-31, and Jax will be in Grand Teton July 20-Aug. 3. While in the parks, the dogs and handlers will assist AIS boat inspectors by sniffing out zebra and quagga mussels and participate in public events.

AIS pose a grave and growing threat to the parks, the surrounding ecosystem, and visitor recreation for these reasons:

  • In 2016, non-native mussels were detected in Montana. This underscores the urgent need to prevent these and other destructive species from entering the parks.
  • AIS can completely transform habitats for native species, introduce disease, out-compete native species, alter food chains, change the physical characteristics of bodies of water, damage equipment, devastate water-delivery systems and negatively impact local/regional economies.
  • Eradication is usually impossible and management is very costly.

The public is invited to learn about AIS and meet the dogs during the following schedule:
