Analysis | Invasives pervasive in US NPs

There has been, for a disturbing amount of time, a slow, creeping invasion of the national parks, one arriving in the form of an ecosystem-upsetting menagerie that poses a significant threat to both native species and the very integrity of the parks.

It is an invasion on land and in the water, one that is attacking wildlife that has evolved with the landscapes. For some parks, the problem has gone beyond being an isolated problem and turned into a malevolent force that is literally impairing the very nature of the parks and some of the reasons they were set aside in the first place.
