" The world is so full of a number of thing , I ’m sure we should all be as happy as kings , " sings poet Robert Louis Stevenson in an disposed sum-up of the wealthiness and diversity in nature ’s plant kingdom . These days , botanical or plant multifariousness is an oft - heard construct , but it can be unmanageable to determine what it intend to the single gardener or homeowner . In an clause published by the University of Kentucky Department of Horticulture , however , Extension Professor William M. Fountain boil it down as the degree of variation in a system in any defined region , from a home landscape to a continent .
Diversity First
" How can you govern a country which has 246 varieties of cheeseflower ? " Charles de Gaulle lamented , reverberate the big issue that many human beings have with diversity . Conservationists agree that the more plant species in an ecosystem , the hefty and more rich it is , yet a stroll down any lane in suburban America offer yard after thou of similar plants set in straight rows . American culture values the refined and the conversant in home landscape , and nurseries offer the plant consumers seek ; as a result , the biodiversity of the country declines .
The More, the Merrier
Biopests are usually picky , bank on only one species or a handful of nearly interrelate species . If an arena has many species , the distance between specimens of the same species increases , and insects and diseases ca n’t hop-skip conveniently from one to the next , decimating an entire species . Almost every clock time a species has been wiped out in large numbers , it grew in single stands , such as the American chestnut tree diagram ( Castanea dentata , U.S. Department of Agriculture plant hardiness zones 5 through 8) , largely eliminated by a legion - specific fungus . This is also true in the home base garden , as demonstrate by the demise of photinia ( Photinia x fraseri , USDA zona 8 through 9 ) and Leyland cypress ( x Cupressocyparis leylandii , USDA zones 6 through 10 ) .
The Dirt on Biodiversity
Gardeners know soil is more than the dirt beneath their feet ; it ’s a living ecosystem filled with being from microscopic bacteria to nightwalker — together with have a go at it as the stain intellectual nourishment web . These organism break up plant debris and win over nitrogen , enhancing and enrich the stead plants ' roots call home . The richer the soil food web , the more prolific the soil . Since the food vane partly look on the plants that acquire in it , the more unlike species you plant , the robust and healthier the soil .
Your Own Backyard
Your industrial plant belong to you , but in a larger sense , they serve your residential district , since diverseness is the sum of all backyard . you could preserve biodiversity by abandoning the estimate that your garden should resemble your neighbor ’s . Do n’t plant overused mintage and blank related specimen far apart in your curtilage . impose your local botanic garden for stirring rather than the neighborhood nursery that likely offers what you see in your neighbors ' thou . Do n’t plant the same veggies yr after twelvemonth . It ’s deserving your metre to seek out different species , especially native species ; not only will this help in creating biodiversity in your residential area , but it will also reward you with fewer garden pests and flora job .
