More awareness?
EG
In Australia farmers can plants thousand of plants a day using a tractor and a 'direct seedling' tractor attachment. I have not seen how this is done, but I have seen the results-- a bushy green windbreak of mixed
local shrubs and trees. You do need people who collect a
LOT of seed as not everything germinates. Here, that involves people who are good shots, shooting the branches with seeds off tall gums.
This organisation gets people involved, and is a good model to use maybe, in other places?
