Isla Sorna Site B Development
The secret nursery where monsters learned to survive before the world knew.
Isla Sorna served as Site B, the secret breeding ground for InGen’s prehistoric creations before they were ever displayed on Isla Nublar. While the first park focused on tourism and containment, this remote island was designed as a naturalistic production facility where dinosaurs could mature in the wild under supervision. Following a catastrophic storm that disabled security systems, the site was abandoned, allowing its inhabitants to roam freely and establish a self-sustaining ecosystem.

Lore & Background
Over several years without human interference, the island evolved into a complex food chain independent of InGen’s control. Herbivores grazed in open valleys while apex predators hunted across the landscape. This environment proved that the creatures could thrive outside artificial enclosures, challenging the notion that they required constant management. The site remains a dangerous testament to genetic engineering gone rogue, where survival is dictated by instinct rather than science.
In Their Own Story
Rain lashed against the rusted corrugated roof of the abandoned processing plant, a relentless drumming that drowned out all other sound. Inside, the air hung heavy with the scent of wet earth and ozone. A shadow detached itself from the gloom beyond the shattered window—too broad for any human silhouette. The researcher froze, their grip tightening on a flashlight until the beam sputtered and died. In the sudden, suffocating darkness, a low rumble vibrated through the floorboards, shaking centuries of dust from the ceiling. It wasn't the hum of a generator kicking back to life; it was the deep, rhythmic exhalation of something massive breathing in the jungle just outside. The realization hit with cold clarity: no one had come to shut it down.
Reader's Guide
InGen bifurcated its ambitious genetic project across two distinct islands. While Isla Nublar served as the glittering public face, Isla Sorna operated as the clandestine Site B—a sprawling naturalistic factory rather than a sterile laboratory. Here, scientists nurtured cloned dinosaurs in open habitats designed to simulate prehistoric conditions, aiming to produce robust specimens ready for transport to the visitor park. Operations proceeded smoothly until a catastrophic hurricane struck the archipelago in the early 1990s. The storm severed power and disabled security systems, forcing an immediate staff evacuation that left critical containment fences unpowered. Without human maintenance, electric barriers failed, unleashing apex predators into the wild. For years, InGen leadership ignored the breach. When they eventually returned to reclaim the island for a new venture, they discovered not a ruin, but a thriving, self-sustaining ecosystem where nature had already rewritten the rules of survival. This transformation turned Site B from a supply depot into the primary setting where humanity faced the terrifying reality that their creations no longer needed them.
Did You Know?
- The name Isla Sorna is Spanish, often interpreted as 'Island of the Snake' or related to serpentine imagery.
- Site B was never intended for public display; it existed solely to supply dinosaurs for the park on Nublar.
- Some species found on Sorna were not present in the original park due to habitat suitability differences.
- The island's ecosystem developed independently, creating unique behaviors unseen in captivity.
