They're talking about doing it on Mars, but I can't
see why this wouldn't by just as applicable to a
Stanford Torus, Bernal Sphere, or so on.

This is nothing remarkable, All Darwin did was bring plants to an island that they would of gotten on anyway had they left it alone and let nature take it's course. Yeah that may be years if not hundreds of years, but sooner or later a bird or animal would of dropped a seed that would of taken root such as it has happened on so many remote islands. This really changes nothing about Mars, it's still hostile. Maybe the least hostile of the not-Earth planets but still is far from welcoming for us to just bring some plants to and hope for the best.

And yes sailorbarsoom this would be easier to do in some kind of habitat rather then a planet with a collapsed magnetosphere, and a thin wisp of an atmosphere.

Mars be grate for mining and research and not much else, at least for the foreseeable future...
