In-situ conservation is the preferred mechanism for maintaining biodiversity (Tuxtil & Nabhan 2003) because through in-situ conservation target species are preserved, along with all associated species. In-situ conservation can be a bi-product of wild collection when a proper evaluation of the ecosystem (Kacalek et al. 2009) and cultural functions (Melloni et al. 2008; Mitchell et al. 2007) is considered.
Ex-situ conservation as an approach for the conservation of habitats is questionable. Taking a species out of its natural habitat and away from the commensurate species who depend on it may preserve that species but will take attention and resources away from preservation of the diversity of life which depend on that species. Native species of plants, algae and fungi have evolved to create habitat and symbiosis with a host of associated species. Introduced and non-native farmed species are disassociated from native ranges and do not offer the same level of environmental benefits. As lands are converted from wild to human oriented use the loss of biodiversity is high, even in agricultural systems with higher biodiversity, e.g. agroforestry and organic (Steffan-Dewenter et al. 2007).
