The habitats of most species have been fragmented by human actions, isolating small populations that consequently develop genetic problems. Crossing between populations is required to reverse these effects, but managers rarely do so. Millions of small, isolated, fragmented populations are likely suffering from inbreeding depression and loss of genetic diversity, greatly increasing their risk of extinction.
Following this advice will often doom small populations to extinction when the habitat fragmentation and genetic differences were caused by human activities. A key reason for such inaction is that managers are often advised to manage populations in isolation whenever molecular genetic methods indicate genetic differences among them. A paradigm shift is required whereby evidence of genetic differentiation among populations is a trigger to ask whether any populations are suffering
