PDC LESSON 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.
