Loss of habitat and fragmentation reduces population sizes and can lower migration rates and genetic connectivity among remaining populations of native species, reducing genetic variability and increasing extinction risk.

Restoration of native species and habitats may also be constrained by low genetic variability and often little is known of the genetic implications or the levels of adaptability present in key restoration species.
