Native species are those that occur in the region in which they evolved. Plants evolve over geologic time in response to physical and biotic processes characteristic of a region: the climate, soils, timing of rainfall, drought, and frost; and interactions with the other species inhabiting the local community. Thus native plants possess certain traits that make them uniquely adapted to local conditions, providing a practical and ecologically valuable alternative for landscaping, conservation and restoration projects, and as livestock forage. In addition, native plants can match the finest cultivated plants in beauty, while often surpassing non-natives in ruggedness and resistance to drought, insects and disease.
Insects need native plants to survive. We need insects alive so that our food and medicine and utility plants can be pollinated and fertilized. Without insects and native plants our biome will experience an ecological collapse. Native plants are the only food that many pollinator insects will consume. Bringing native plants back into our environment is essential to the survival of humans, fauna and flora. Once the insects are gone, then will fall the birds, squirrels, foxes, rabbits, deer, and other fauna. The food chain will collapse.
