When all these are achieved, there will be the formation of a basis for reclassification of the species from the endangered category to a lesser affected category, popularly known as down-listing.The Karner blue butterfly is a species that have for once been federally listed as an endangered sort range-wide (Charde & Martin, 2012). In its history, the species occurred in twelve different states and sites in Ontario Province. Currently, the blue butterfly has been reported to have gone extinct in seven of the states, and having massive occurrences in the western range. In the five states, the species has been considered extirpated. Reintroduction of the species to the said states could be achieved through translocation. Historically, the species is said to own or inhabit the savanna ecosystems. Due to the development, much of the ecosystems have been destroyed without replacement leading to lack of habitation for the organisms. This eventually led to decline in the locations and numbers of the Karner blue, marked by loss of large populations. This was especially evident in the eastern and central quotas of its range (Moores et al. The remaining savanna and barren habitats among other sites that support the habitat acts as a home for the Karner blue presently. These include such places as the military bases, rights-of-ways, silvicultural zones and airports.The bio network of the blue butterfly is closely related to the habitat in which they garner food and other sub habitats. In its larval stages, the species feed on a specific plant, the wild lupine without which the regeneration of the species cannot thrive. Conserving such plants within the habitats is highly recommended and should not be left in isolation while strategizing for recovery of the species. The adults on the other hand feast on nectar for survival and reproduction. As a result, to renew the existence of and persistence of the species, managing and revamping these habitats is eminent. The dynamics and distribution of the above habitats, therefore, forms the basis for setting recovery plans to establish a sustainable meta-population.There exist more than a thousand different plans set to aid in the recovery of the endangered species. A requirement by the law for all the plans to have an "objective, measurable" criterion for delisting was a positive measure enacted through a constitutional amendment in the late 1980s. The size of the population for a
