Migrating Forests is a colony event chain that has a very small chance to trigger 2 or 3 years after any colony has been founded. It can only happen once per game. The event chain offers two mutually exclusive paths which both have eventual rewards and drawbacks.

Migrating Forests

Evt alien nature.png

The surface of [colony name] is covered in lush forests, with massive tree analogues rising hundreds of meters into the air. Interestingly, our colonists have found that nearly all of the flora is mobile to various degrees. Forests stretching for miles will slowly migrate to new areas richer in nutrients in a cycle that seems tied to the [planet or moon]'s orbit.

Unfortunately, this has seriously hampered our efforts to develop the colony's infrastructure. The migrating trees frequently cut power lines while smashing our buildings and roads into rubble.

Special Project Completed

We have learned that the roaming forests on [colony name] avoid certain regions that are home to colonies of a native pseudo-insect. These insects secrete a pheromone that can be used to steer the wandering trees away from population centers.

Furthermore, the areas where the forests most frequently range have been closed off as nature reserves. Our biologists can learn much by studying this reserve from the neighboring regions.

Special Project Completed

A napalm bombing campaign has been effective in decimating the migrating forests on [colony name]. The massive firestorms have left a smoldering landscape in their wake, in which our ecologists have planted more traditional and significantly less mobile off-world trees. Losses to the [planet or moon]'s wildlife have been substantial, but within acceptable limits.

Forest Adaptation

Evt alien nature.png

Continued interaction between our colonists and the wandering forests on [colony name] has revealed that the trees are in possession of some form of rudimentary communal intelligence. They seem to have adapted to our presence, and now go out of their way to avoid damaging the property of our colonists even without the use of the insect pheromone. Spirits among the colonists have risen.

Mineral Deposits

We have discovered several significant mineral deposits that had previously been obscured by the roving forests on [colony name]. Now that the trees have been reduced to ashes, the deposits are easy to access.

Forest Research

We have learned a great deal by living in proximity of the wandering forests on [colony name]. Some enterprising colonists have even built homes in the treetops of some of the larger specimens, following the forests around as they migrate across the planet. Some of the foremost biologists in the [empire name] have spent time studying these unique trees.

Forest Fire

A forest fire caused by lightning on [colony name] created something akin to a stampede among the [planet or moon]'s wandering forests. Their wild panic brought them into areas they had previously avoided, resulting in widespread damage to the colony's terrain.

Ecological Damage

Evt alien nature.png

It would appear the migrating forests we exterminated on [colony name] played a more vital role in the [planet or moon]'s ecology than previously thought. The wildfires we started and the absence of the forests have led to the extinction of several local species, resulting in a domino effect that has claimed several species of predators as well.

Efforts are ongoing to at least partly restore the fragile ecological balance by introducing new flora and fauna from other worlds, but it is a difficult process that will take time.

Wandering Forests Migrate

The colonial authorities on [colony name] have reported that one of the local wandering forests has migrated to another region on the [planet or moon]! Hundreds of thousands of trees have uprooted and marched in unison to this new area, trampling everything in their path.

Rise of the Trees

Evt alien nature.png

The migrating forests on [colony name] have resurfaced! We knew isolated pockets of their kind had survived in several remote areas, but they appeared dormant. It seems they used this reprieve to replenish their numbers, and they have begun to systematically attack our settlements.

Contrary to what we believed, they clearly possess some form of rudimentary intelligence, and they're out for revenge!
