National Parks in America are under the severe threat of presence and spread of invasive species. To ensure the survival of these natural treasures, National Park Service has asked a panel of experts to chart a plan.
The journal Biological Invasions published the experts’ findings.
Ashley Dayer, Assistant Professor, Wildlife Conservation, College of Natural Resources and Environment is the lead author of the paper.
National Parks reported 1,409 populations of 311 invasive animal species. The invasive species include – reptiles (includes the Burmese python), mammals (includes cats, rats, feral pigs), aquatic species (includes the quagga mussel and lake trout), etc.
Expert findings are -
• the mission of National Park Service can be undermined by invasive species. They can cause -
- Loss of park wildlife
- Introduction of diseases
- Lessen visitors' enjoyment of parks
- Pose economic impacts due to the cost of control measures
• To meet the challenge of invasive species, coordinated action is required
• Collaboration is important that includes -
- Public engagement, support and co-operation
- Strategic decision support across all levels
- Emerging technologies
Findings also identifies that ‘public’ have an important role to play in the entire process.
Ashley Dayer states that "The national parks are not the National Park Service's parks; they belong to the U.S. public and serve as conservation models nationally and internationally."
