I'm going to elaborate some here as I feel that this may be a good guild for many new sites in the Pacific North West.
A simple hypothetical native planting design for a square empty lot of your choice. I'm sure someone creative could come up with at least one more plant, fungus, or animal to introduce. I will build from the canopy down, which is apparently the way you
should do things. This is not a design system that could provide all of your food needs or provide food overnight. One could mange this system as a sort of 'edible woodlot'
Alder - Used for timber, food for high protein mushrooms, nitrogen fixing, and soil building.
I often see alder bunched up in insanely dense patches along the worst of fill dirt. The kind found along along tortured roadsides. They get mowed, sprayed, flooded, baked, and they just keep on growing. Poor Soil? Rocky soil? Wet soil? No problem. Plant them as close as you feel comfortable. Plant thrice that many. If you have alder seeds and a 'plant-it jr' and put them in like you would freaking carrots or salad mix. Plant every other square centimeter with nettle.
They'll grow. Quickly. And fix nitrogen.
Nettle - All parts usable. Seeds, leaves, and rhizomes are edible. Stalk can be used for fiber and cordage. Crop and drop soil builder.
Compost maker. Child deterrent.
By the first fall you will be needing to chop and drop. The smaller you chop it and the move it gets worked into the soil the quicker they'll rot. Alder leaves will of
course fall annually raining fresh mulch down to the floor of your new native forest.
I'd be looking for something like 1 4-5" alder per 2 feet by year 3 or so. And continue thinning and opening up space from there on as I needed. At this point your alder is mature
enough to inoculate with oyster mushrooms. You could stack these along your path in the shade.
Oyster mushrooms - A Primary Decomposer. Fruit Bodies are edible and high in protein.
By year five you'll have an alder forest with 6' trunks 3 feet apart - probably with with little cleared sunspots where you're nettles would be doing particularly well (Nettles glory is in coming ups so early - its a foot and a half tall by the time any other leaves are unfurling - so you'll have it everywhere not just the clearings)
I'd cut down a few more
trees - chip the branches - inoculate the trunks - and plant some Salmon Berry thickets in the clearings and thimble berries along any available edge. Or Try trellising black caps up alders and through salmon berry bushes. Stay alert though because they will also creep as a ground cover (but not fruit in the shade of an alder canopy) and can compete with even the mighty nettle.
This is the point where one would be tempted to branch out into non native species.
You can use you're imagination for year ten or 15. I'd probably have a nice little alder grove where the center had been turned into a peaceful clearing perhaps with a rock
pond. As time goes on one the Old alder will naturally snag and turn into food producing spore broadcast towers. Nettles everywhere you want them.
Good eatin' and more importantly good for the
land.
One final note:
One you start chop and dropping and/or chipping you are almost certain to get a forest floor cover of wavy caps. BEWARE THIS PESKY PSYCHEDELIC. It has a mind of its own and is clearly bent on
world domination. For this reason it has been outlawed both locally and nationally.
