|Complete Wildlife Preservation||19||Mordecai (Sanctuary)||3527 XP, Sniper Rifle|
The engineers working in the Hyperion preserve are still alive and Mordecai wants to fix that by releasing the creatures they were working on. Fast travel to the Wildlife Exploitation Preserve and you'll see three different waypoints. You'll have to go to each one, free the animals, then kill the guards that spawn. Each location will have twelve guards for you to kill, so there's no differences there.
You will notice that there is an optional objective to keep seven creatures alive during the mission. There should be more than enough animals needed for the optional objective, as it's possible to get five just from the first encounter. However, since the creatures are normal ones in the first two, the guards might make short work of them; this isn't the case with the final encounter, as you are protecting a Badass Stalker. Just make sure you clear the area of enemies before you free the creatures you need to release, as this will limit the number of enemies that could go after the animals. Return to Mordecai once you're finished.
