Mario, sorry for such a slow reply! Where are you in the world? The
steps taken to reforest a place depend a lot on the place, the
current state of the land, and the availability of indigenous seed
to the site (without your help).
If I were you, I would look at what nature would do if you didn't
do it, and try to speed up that process (stacking functions,
stacking time). Try to get lots of organic matter (in basically any
form) in there and spread it on the ground. It doesn't need to be
composted. Then plant in the shrubs, legumes, and other small trees
that would come up first. Once you have this process going, you
could come back in a couple years and put in some more climax
(dynamic equilibrium) species, or just let nature do it from there.
If you are in the tropics, the thing will take off and before you
know it you have a fully stratisfied forest!
A helpful resource to check out, especially for wet/dry tropics is
call forru (Forest Restoration and Rehabilitation Unit) out of
Chiang Mai Unversity in Northern Thailand. You can download their
book:

I hope that helps, and thanks for replanting!
