I have been working toward a permaculture garden and landscaping with native species. Mostly consisting of small slow changes to increase insect habitats and food sources for local fauna. A local nature conservation program nearby sells permaculture plant sets to encourage the use of non-invasive species. I think the idea is gaining awareness. You might enjoy the documentary biggest little farm.
Food forests, permaculture. Thoughts? ( beehaw.org )
Personally I find these both awesome ideas but I wonder about their scalability for larger communities. Does anyone have experience with them?...
