JP: Fences
Isla Nublar
^ Tyrannosaur Paddock fence.
Fences were first seen in service on Isla Nublar. They were anywhere between ten to thirty feet tall. They had a minimum of 10,000 volts of electricity to stop the dinosaurs from attempting escape. The fences are clearly shown to be thick metal supports with electric wiring connecting them, with different versions depending on the paddock and location.
^ Dilophosaurus fence.
Some also had concrete moats near them, such as the Tyrannosaur Paddock. Smaller fences, between five-to-eight feet tall were found near the Dilophosaur Paddock.
^ A stretch of perimeter fencing, of which would line the park. Notice the thin wire interconnecting the larger wires.

Isla Sorna
On Isla Sorna there were several broken down electric fences. A perimeter fence that lined the Worker Village and a stretch of specialised fencing near the Aviary observatory.
^ Worker village fence.
The Worker Village fencing utilized the same type as the perimeter fencing on Isla Nublar complete with the same style gating. However, the elements had taken their toll on them and by 1997 the wiring and support poles were sagging. Even with the deterioration, the fencing still is capable of running electricity as evident by the lights atop each pole being lit up when Nick Van Owen restores the power to the compound in order to send a distress call.
^ Isla Sorna "aviary" fence.
The fencing outside the Pteranodon aviary as seen in Jurassic Park 3 is very heavily built. A row of thick, albeit hollow bars run parallel to the ground, with the inner sidelined with meshed cable wiring. The topmost bar, roughly 30 ft or more in the air, is armed with large spikes pointing in all directions. Each section of fencing is connected by large triangular beams. Due to the age of the fence and lack of maintenance, the Spinosaurus crashed through the fence with ease.
