Ellie Sattler was a graduate student under Dr. Alan Grant during the Nublar incident. She was a paleobotanist, a scientist that studies prehistoric plants, and was asked to come to the park by John Hammond, hoping she would endorse it. Sattler agreed, and was, like Grant, originally thrilled with the prospect of Jurassic Park. However, she too saw the dangers of mixing dinosaurs with humans, mostly after discovering the staff at Jurassic Park had paid no attention to the plant life around them. They placed poisonous plants around the pool and other public places, showing their ignorance. During the tour, Sattler helped solve the problem as to what was ailing one of the park’s Stegosaurus. She discovered the cause of the ailment was accidental ingestion of Melia azedarach (West Indian Lilac).
She then took the jeep with Gerry Harding and Donald Gennaro to the Visitor’s Center. She helped Harding take care of Ian Malcolm’s injuries after he was rescued. During the final power outage, Sattler used herself as bait and distracted a number of Velociraptors trying to get into the Safari Lodge. After Tim Murphy restored power, she accompanied Grant and Gennaro to the raptor nest to document the number of animals that survived. She escaped the island alive, and later married a scientist at Berkeley and had two children.
