I want to make the local ecosystems stronger. Native plants should grow well, but there are also many organisms around to fertilize them, prey on them, symbiose with them, eat their fallen leaves, and so on. Everything else in the ecosystem from the microbes, fungi and insects up is native, so it seems obvious to me that the plants should be as well.
