Basically, Isla Sorna was where InGen was able to experiment with dinosaur creation in a less controlled seeting, and could go wild and try dangerous things.

It was also intended to be a place for younger animals to mature before being moved into the park, Hammond was also keen on the idea of Sorna being a zoological reserve, somewhere for scientists to study the dinosaurs in their natural habitat.
