Bio-diversity supports below ground and above ground species:

There is more bio-diversity in the trophic levels below the ground. For example there is a plethora of microorganisms, insects and other creatures that inhabit the earth in the below ground levels. So leaving areas of the landscape as natural and undisturbed as possible will greatly enhance the survival of these organisms. Remember it is the interaction among species that contribute to a bio-diverse garden. Even small practices such as recycling all the leaves in your yard will enhance beneficial fungi and other organism that thrive on organic matter. In turn, these interactions cause other reactions such as earthworms and other creatures to inhabit the soil, even in your own backyard. Many non-gardeners are interested in the visible above ground components of the landscape because that is all they can see. The most critically important part of the landscape is the below ground component of the garden as it contributes ton the health and resiliency of what grows in it.
