The impact on the natural habitat is of great concern at present. Increasing demand could force the destruction of natural habitats, breeding grounds, removal of winter cover, shelter beds for some species. Mechanization of agriculture saw the destruction of nests, burrows, etc. Similar impact but with greater intensity can be expected to result from energy crop plantations. Extending energy crop farming into unusable, non agricultural land can have a negative impact on that particular eco system. However, generally, energy crops are believed to have the potential to support a diverse eco system and support genetic biodiversity. Although, energy crops cannot act as a substitute for natural habitat, they can act as a support for early to mid succession species. .
