Experts in conservation, invasive species and park management recently published a study in the journal Biological Invasions about how US National parks are struggling to protect their national habitats and wildlife. The spread of invasive species is to blame. To overcome this challenge, the authors recommend coordination among stakeholders and the appropriate use of emerging technologies.

The paper presents a detailed review of the invasive species and their management by the National Park Service. The invaders include mammals such as rats, cats, and feral pigs; aquatic species like lake trout and the quagga mussel; and reptiles, including the Burmese python. Statistics reveal that of the 1,409 reported populations of 311 invasive animal species in national parks, there are management plans for 23% and only 11% are being contained.
