They dig, hunt, nest, mate, breed, defecate and die in and on the ground beneath the stacks. The wind carries seeds which hit the stacks and drop to the ground. After rain the moisture is retained for longer because of the micro tillage and reduced evaporation. The natural mulch from wind blown vegetation and old growth plus the moisture allows the growth of fungi. The environment is now suited to earthworms which may discover it on an evening migration.
Natural symbiosis is at work.
Within three years we need to extract our stacked material from the mini jungle and find another degraded area for storage. The once degraded soil has been tilled, fertilised and conditioned by a host of microbes and animals in symbiotic relationships. That wraps up this session.
