The hirola antelope, is the world's most endangered antelope, with the primary problem being, fewer than 500 individuals are left. The decline began in the 1980s but has continued due to an ongoing, complex environmental issue. The loss of the hirola would be the first extinction of a mammalian genus on mainland Africa in modern human history.

Here is a timeline of the key events that led to their current crisis:

-A rinderpest virus outbreak, caused the initial crash, as it claimed 80-90% of the hirola population and this is the main reason hirola cannot recover.

-Loss of Grassland, attributed to widespread elephant poaching. Elephants are crucial landscapers, that turn down woodlands to grasslands. Elephants naturally knock down trees and clear land, maintaining the savannah. Their absence allowed woodlands to take over. Hirolas are specialized grazers that depend on short, new grass and open landscapes with less than 30% tree cover for feeding and spotting predators. The area has since then, seen tree and shrub cover increase by approximately over 250% in recent decades, severely reducing their food and space.

-Increased Competition: The growing human and livestock populations in their range has led to, direct competition for the remaining grassland. Hirola are often displaced by cattle and other livestock.

Other pressures compound the habitat issue

• Natural Predators: Lions, cheetahs, leopards, and hyenas prey on hirola, especially calves.
• Genetic Vulnerability: The tiny population is at risk of inbreeding depression, a concern noted in the translocated Tsavo group.
• Disease Risk: Living close to livestock puts hirola at risk of novel disease outbreaks, which conservationists actively monitor.

Conservation focuses on habitat restoration and protection:

1. Predator-Proof Sanctuaries: The most successful effort is the "Ishaqbini Hirola Conservancy" a fenced, livestock-free sanctuary. Since 2012, its founding population of 48 hirola has more than doubled and has even tripled according to some reports, proving they can thrive with protection.
2. Active Habitat Management: Conservation programs are 'clearing bushes, reseeding native grasses, and working to bring elephants back' to the ecosystem to help control tree cover naturally.
3. Community Partnership: Success hinges on working with local Somali pastoralists. Efforts include providing water for livestock and supporting community governance of conservancies.

Why It Matters:

The hirola is the last remaining species of its entire genus (Beatragus). Its extinction would mean the loss of a unique branch of the evolutionary tree.
