From India. Helped grow one Miyawaki mini forest
(* we did make a few short cuts so its a 70% there mini miyawaki) in the common area of our buildings.
Hope other people do too. We need more trees. This is a way to get a thick cover in less space. Basically go 3.5 feet down (atleast so soil is dug up) Mix compost, fallen leaves, some thing like corn waste or sugar cane waste of rice husk to loosen soil, coconut shells broken in to small pieces (cocopeat) to hold water) and plant native to that area trees, very close to one another, taking care to grow trees that grow tall (30+ feet) near 2-3 that grow less (1 10-20 feet high, other 2 20-30 feet high) so they take up different vertical spaces when grown, kind of like flats/ apartments)
See https://www.youtube.com/watch?v=FfA2namCs7Y We did one in muy flats. Very proud after 1.5 years see images at https://photos.google.com/share/AF1QipNNT15rSFTjGa_SGT3EbIvxEMly2f_XxfZb.
