You need more than a "keep off the grass" sign when chipmunk/wolf Animats are around the place!

This is a typical sight at night on Lantrei. Because there is only eight hours of daylight during any one day, and twenty four hours of night (well, technically eight hours of dusk, eight hours of night, and eight hours of dawn), lighting is a necessity. When the Colonists finished terraforming the planets surface, they genetically engineered plants to be bio luminescent. To this day parks and a lot of public spaces are illuminated by plants and other 'natural' kinds of lighting.
