Your terraforming group (Military, science, etc.) is sent to "Remove by any means necessary" a non-sentient native lifeform that is interfering with the company's schedule.
{Everything is available here. From a military expedition to remove the Alien Hive Queen, to a peaceful attempt to gather Tribble Herds and find a new habitat for the little buggers.}
{This can also be as simple as "Go do job and leave" or as complicated as "What will the long term effects to the native environmental habitat be if we remove this creature." Even if it is the Alien Hive Mother.}
