Jurassic World Evolution 3 Birth Control Mod v1.0
November 5, 2025 - 8:45am
Birth Control is a gameplay and quality-of-life mod for Jurassic World Evolution 3. It helps prevent uncontrolled breeding by reducing the population cap for every species in a territory and lowering clutch sizes for slower population growth. When the herd reaches its cap, breeding stops automatically, keeping your park balanced and easier to manage.
Main Features
- Lowered Population Caps: Each species has a territory population cap between 8 and 16, based on their breeding archetype, for tighter control.
- Reduced Clutch Sizes: The number of offspring per breeding is limited, so herds grow much slower than in the base game.
- Automatic Breeding Halt: When maximum population is reached, breeding stops and nest interactions display “Too many dinosaurs in territory.” Females also show “Max herd population reached” under breeding chance info.
- Standalone and Safe: Works independently of other mods and should remain compatible after game updates.
