1.12 PRINCIPLES OF ACCELERATED SUCCESSION &
EVOLUTION
Direct and accelerate the succession and evolution of your system.
TECHNIQUES TO ACCELERATE SUCCESSION
Use what is already growing,
usually a weed layer, to build soil fertility.
Introduce plants that will easily
survive in the particular environment, and which will help to bring up soil
fertility (e.g. legumes).
Raise organic levels artificially
by using mulch, green manure crops, compost and other ”natural” fertilisers. 
Substitute your own herb,
pioneer, and climax species which are more useful.
PULSING (Holmgren)
“The use of fire, grazing and
cultivation to provide a pulse of high yield between longer phases of
biological rebuilding can be recognised as strategic use of change against a
background of catching and storing energy”. 
Through following natural
patterns and assisting instead of fighting
the life forces we can rapidly turn barren areas into lush and fertile systems.
