Some Cross River gorilla subpopulations number fewer than 20 individuals within a single forest region.
Because Cross River gorillas are distributed across scattered forest fragments, individual mountain blocks can contain entire extended family lineages. In some regions, fewer than a dozen individuals inhabit a single protected area. If that forest were cleared or severely degraded, a unique genetic branch of the subspecies could disappear permanently. Unlike larger gorilla populations where loss in one region is buffered by others, each Cross River subpopulation carries irreplaceable DNA. Their isolation means local extinction is global extinction for that lineage. Conservation surveys have identified multiple micro-populations separated by farms and villages. Each functions as a fragile genetic vault.

When population size drops below several dozen, genetic drift accelerates dramatically. Rare alleles can vanish within a few generations. For Cross River gorillas, losing even a small forest enclave can eliminate traits that evolved over millennia. Such erosion is invisible to the naked eye yet biologically profound. This dynamic makes land protection exponentially more urgent than raw numbers alone suggest. Protecting one hillside forest can preserve thousands of years of evolutionary adaptation.
The concept challenges how extinction is perceived. It is not always a dramatic global wipeout; it can occur piecemeal, ridge by ridge. With fewer than 300 individuals total, every local forest block is a final stronghold for something genetically singular. In practical terms, bulldozing one valley could erase a family tree older than recorded human history. The survival of Cross River gorillas depends on safeguarding these micro-refuges before they quietly disappear.
