Jurassic World Evolution 3 Birth Control Mod v1.0

                    
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.
