A healthy ecosystem has the resilience to deal with adversity. Populations of individual species fluctuate through dry spells and extreme wet ones, excessive heat and cold. However, the great diversity of species allows the community as a whole to retain its overall cohesion.
Every species prefers different foods, and in turn contributes different value-added products towards someone else’s food supply. The greater the biodiversity, the greater the overall fertility of the soil and the chances that all will find exactly what they require for optimal health.
Allowing the garden to recycle its own waste in place creates optimal biodiversity; and with that optimal soil fertility and water holding capacity. In a commercial setting this practice is difficult to accept, as the desire for that manicured look is almost a must. The application of mulch to these landscapes is a great alternative and gives the soil some biodiversity to work with
