[QUOTE="Fenris, post: 2958496, member: 2820"] Indeed, traditional views of terraforming consist of the introduction of non-native, oftne invasive plants intot he new environment (whether terrestrial or another planet). If you want plants to grow you will need some carbon dioxide in the air. Enough plants can generate the oxygen you need. May I suggest that in addition to your native microbes you add some primitive lichens. They would be able to survive the cold and dry conditions, but during the once-a-year rain storm, they could flourish and thus justify why you have any oxygen there at all (unless the planet used to have more water). The other nessecity for both a heavier gravity field and more oxygen is of course ozone. Without a decent ozone layer, the humans will not be able to move around without special equipement (SPF 2,000 doesn't count :) ) Not even restricting life to canyons will help that. One thing to consider in regards to plants and temperature in general is the rotation of the planet around it's star and the rotation of the moon around the planet and the rotation of the moon itself. How much light and dark time will you have? Too much time behind the gas giant will cool the planet too mcuh for life, too much time in front of it could heat it up. I see wide temperature swings here. Maybe life is restricted to the poles where the temperature swings aren't as bad. [/QUOTE]
