Site B Abandonment

Lore & Background

The abandonment of Isla Sorna began when InGen diverted resources to its public-facing park on Isla Nublar, leaving Site B vulnerable. Once staff evacuated, the dinosaurs were left to live freely and reproduce without human intervention. Unlike the juvenile specimens at Nublar, the animals on Sorna had years to mature in isolation, adapting with brutal efficiency to a feral environment where natural selection was the only law. The source highlights that this ecosystem eventually suffered a breakdown after illegally-cloned animals were introduced there, as noted by a promotional website for Jurassic World: Fallen Kingdom. Despite the chaos of abandonment and subsequent genetic contamination, the island remained a critical location in the franchise's timeline until the surviving dinosaurs were relocated to Isla Nublar.

In Their Own Story

The narrative of Site B shifts from controlled science to wild survival following InGen's departure. The source specifies that the island is part of a five-island chain called Las Cinco Muertes, or "The Five Deaths," though only Sorna plays a role in the novels and films. By the time of Jurassic World: Fallen Kingdom, the ecosystem had destabilized due to the introduction of illegal clones. The story arc culminates with the surviving dinosaurs from this broken ecosystem being moved to Isla Nublar. While the source does not detail specific evacuation radio transmissions or the exact moment power failed, it confirms that InGen's retreat left the facility in a state where predators and herbivores established their own territories until the island's fate was sealed by external intervention.

Reader's Guide

For those tracking the timeline of Site B, the source establishes its geography first: 140 km southwest of Isla Nublar. Its primary function was incubation and rearing, distinct from Nublar's role as a showroom. The key turning point occurred after the events of the first novel and film when InGen abandoned the site. A promotional website for Jurassic World: Fallen Kingdom provides the specific detail that the ecosystem suffered a breakdown due to illegally-cloned animals. This period of isolation allowed dinosaurs to grow into robust adults, creating a population distinct from the park stock. The guide concludes with the relocation event where surviving dinosaurs were moved to Isla Nublar, marking the end of Sorna's era as an independent feral preserve.
