Invasive Species
Dandelions. Those pesky, resistant weeds are EVERYWHERE. They are an invasive species in Denali, and pretty much everywhere else. Dandelions are much tougher than they look, and could easily win a Hunger Games for Plants. They put deep roots in the soil, and choke all the other natural vegetation. They will pop up everywhere in the park, and will take over the area. Dandelions are not killed easily, their roots will allow them to keep popping up.
