Ecosystem Takeover
The "Ecosystem Takeover" event in Stellaris — flavor, choices, and how to trigger it with the event console command.
Ecosystem Takeover

The … on … has recently started settling new regions of the planet. The local flora and fauna, initially vastly different from what can be found in the settled territory, are being completely taken over by the collective, who is taking a radical but methodical approach to regulating the local ecosystem. Certain animal species are ruthlessly exterminated only to be replaced by others, while invasive vegetals choke out the life of the indigenous trees. The native's ecological mastery is remarkable, yet they cannot avoid certain setbacks in areas of unusual climate, where the introduced lifeforms cannot survive long. We believe that they shall soon find a way around these obstacles and eventually, the whole world will be uniform, presenting optimal conditions for the collective to thrive in.
