The ecology of Gaeleth is that of an alien world, with species unique to Gaeleth and the SisterWorlds in each of its ecological biomes. Below is a list of biomes, complete with typical encounters within those biomes. Terran life forms are introduced species to the world, and no one is certain how many of the other life forms are native, or came from other worlds than Gaeleth. Some biomes overlap in the overall ecological scheme: mountain forests, for instance, can be found in both 'mountains' and 'forests' entries. Terran examples of biome locations can be found at http://www.statemaster.com/encyclopedia/Biome.
