VERY unfinished so far. So far the basic area has been fenced in, but eventually it'll be expanded, the spawn (and the safe area) have been protected and given some equipment, and a few handfuls of dinosaurs have been spawned.
You'll need the Jurassic Park Rebuild V3.3.2 texturepack to see this map to its full extent, or the pictures won't look right, and the JurassiCraft 2.0.3 Pre-Release mod. You'll still be able to see some dinosaurs with a lower grade of the JurassiCraft mod, but mutliple dinosaurs and features won't be available unless you use at least JurassiCraft 2.0.0 Pre-Release.
By default the gamerule dinoMetabolism is set to false to prevent the dinosaurs from starving as I work on this.

A note: Even though I've hinted about adding JurassiCraft's Indominus Rex to the reserve, I'm holding off because it will kill everything.
