Isla Nublar

The ecosystem of Isla Nublar post Jurassic World was considerably more unstable than previously, largely due to the presence of a much greater number of large carnivores on the island. This led to over-hunting and competition, with a number of species falling back into extinction after the fall of Jurassic World.

The reactivation of Mt. Sibo threatened with destroying, or at least, devastating Isla Nublar, thus endangering the surviving dinosaur population. With the eruption of the island in 2018, around half of the dinosaur species present on the island were rendered extinct with the remaining population transported to the mainland United States.
