Plant species recovery programs are enacted when naturally occurring diversity of a species or population falls close to or below what is considered to be a sufficient size for the species to continue to exist without human intervention. The purpose of these plans is to ensure the long-term survival of the (axon concerned, and where possible, to re-establish self-sustaining populations in their natural habitat. In such an endeavour to increase plant numbers, there exists a risk that seed, soil, machinery and plant material used in the introduction of plants to native habitats will include the introduction of phytopathogens capable of destroying the very population that we are attempting to increase. Alternatively, changes to environmental conditions created by the activity of the program may favour disease development by native or naturalised pathogens. For these reasons, phytosanitation (literally, plant-health-process) procedures are employed to minimise the threat of pathogens already at a site and, more importantly, to prevent infected or infested material entering a site.
