Arctic plantlife covers a group of plants that are suitable for aiding in the terraforming of subzero worlds. They can be seeded on worlds that have either no or very little life in order to establish vegetation in regions that currently have none. Normally 1,000mu's of arctic plantlife is required in order to convert a flat lifeless terrain into a vegetation (probably tundra) terrain.
This plantlife can only be used on a world that has a breathable atmosphere.
Multiple sectors can be seeded in a single special action although the GM is the final arbitrator on what will be effective.
