Re: [fukuoka_farming] forest restoration
- hi bob,
clear-cutting exposes the forest floor to intense insulation & evaporation &
deep compaction if big machines were used... as a result, the normal soil
life of fungi, bacteria, worms, microscopic plants & animals of all kinds
are destroyed & with fauna & flora of open lands coming in...if the
clearcutting has taken place a long time ago the soil may be by now totally
lacking mycorrhizae so it's possible that the vegetation growing now is
associated with bacteria instead & not at all the type that was there with
the original forest...
try to find in ur region an untouched old growth forest corresponding to the
same elevation & natural range than ur land, to collect seeds from it, the
tree planting should rely on a wide mix of natives species to promote &
restore the forest ecosystem with their complete set of native species &
structures: if the site is really downgraded it may be necessary to start
with tough, pioneer plants, & years later plant in later succesional species
& u should as well collect soil (it should not dry out or been left too long
exposed to the air) from the rhizosphere level of the younger trees of the
mature forest from where u gather the seeds to inoculate the tree seeds
with,( it's necessary to put back all the living critters & their feces back
to the soil, soil arthropods are the regulators in most soil processes, they
are the system catalysts that drive the microbial processes of chemical
excitement & ensure the health & long life of the young trees as they keep
start the seedlings, either directly on the ground making an small hole &
depositing an small handfull of the collected soil in it with the seed, or
start the seedling in the collected medium in a nursery but transplant as
soon as sprouted early spring with the collected soil & being very careful
not to shock the tree when transplanting as it can slow its growth rate for
years beside fragilising it to diseases, either way once in the ground the
seedling must be protected from predation, protecting also the soil with
coarse woody debris, perhaps using bud-caps to protect the seedlings from
browsing & from excessive light...imitating a canopy is not easy but
essential for the good developement of the trees. perhaps u can start with
planting alders which have a quick growth, leave a lot of leaves to feed the
soil & u can remove later when the natural species are well stablished.
consider as well the setting up bird boxes on poles to increase their
natural habitat: they'll work as pest predators.
what about roads in that land?
