TAWI ATAIR, Oman — Several thousand feet up on a jagged escarpment overlooking the Arabian Sea, Hadi al-Hikmani has come searching for a shy and reclusive creature.

The Arabian leopard, the last remaining big cat in the Middle East, is almost invisible in the canyons and dry riverbeds of Oman. So even a growl or a scratch mark would satisfy the conservationist. But al-Hikmani looks set to go home empty-handed as he has so many times after his treks across the Dhofar mountains in the Jebel Samhan Nature Reserve of southern Oman.

Then his luck turns.

“Here we go!” yells al-Hikmani as he comes upon a pile of leopard droppings that appears several weeks old. He and a colleague bag the waste, which later will be genetically analyzed to help determine the leopard population in the area as well as the prey. This leopard seemed to have a taste for porcupines, small rodents and hyrax, a plump, rock-dwelling mammal.

A few hundred feet up the path, further good news. One of the more than 25 camera traps that dot these mountains caught an image of a leopard — its pale coat dotted with black rosettes and spots standing out against the darkness. It was just a bit larger than a golden retriever and was the first one caught on camera for several months.

“It’s a good indication that the leopard is still using this area,” said 30-year-old al-Hikmani, who works for the Oman government’s Arabian leopard project and wears a traditional Omani headdress over Western hiking attire. “Maybe one day we will come up here and won’t even see any leopards. So we are quite excited.”

For conservationists, these are small victories in the race to save a species.

Once thriving across the Middle East, the Arabian Leopard is now considered critically endangered by the International Union for Conservation of Nature. It estimates there are fewer than 200 in the wild with the largest single population of 50 to 100 in the mountains of southern Oman. There also are small populations in Yemen and Israel’s Negev desert.

The animals’ range is increasingly fragmented by development, overgrazing and herders who shoot or poison them lest they prey on their goats, cows and camels. Leopards in Yemen are under threat from poachers who supply a vibrant exotic animal trade in places like the United Arab Emirates.

“They are at a critical point,” said Andrew Spalton, a Briton who advises the Oman government on environmental affairs and has worked on leopard conservation for 16 years.

“Inevitably, they are going down. That’s because of loss of habitat. Where they are hanging on are areas that people find most difficult to get into with their livestock and their four-by-fours,” Spalton said.

The immediate challenge is to count them and figure out their gender ratio.

“The official estimate given is there may be 200 Arabian leopards left between Oman and Yemen (at opposite ends of the Arabian peninsula). It’s probably half that number and may even be lower. We don’t know,” said Tessa McGregor, a British conservation biologist.

McGregor is working with al-Hikmani on a five-year project supported by the nonprofit Earthwatch Institute and the Omani government to gather data on the leopards in Jebel Semhan, train Omani scientists and raise awareness of leopards in communities and schools.

But al-Hikmani and others know that research alone won’t save the leopard, and are exasperated that their work isn’t matched by stronger action on the ground.

Nothing has been done to combat the rampant overgrazing by livestock that denudes the Dhofar mountains, and enforcement of Oman’s laws protecting leopards is weak.

The hope is that next month’s Oman-sponsored conference on the leopard will result in more coordinated approach to saving the leopards.

The gathering of Omani officials will weigh such proposals as compensating herders for reducing their herds and curbing the area’s unchecked development.

One option not on the table will be to reintroduce leopards into Oman from the more than 80 captive-bred leopards in nine locations on the peninsula.

At the Breeding Centre for Endangered Arabian Wildlife in the emirate of Sharjah just north of Dubai, the leopards are caged and almost docile when humans approach, and they would make easy pickings in the wild.
