(CNN)Van Zyl's golden mole is an extraordinary creature. It is more closely related to elephants than to the moles you might find in gardens and parks. It has no visible eyes or ears and it "swims" just below the surface of South African sand dunes.

This endangered species has only ever been found in two locations, both inside the Succulent Karoo desert. It's just one of the rare creatures found in this otherworldly landscape that stretches between Namibia and South Africa -- the most biodiverse arid desert on the planet, according to UNESCO.
Home to more than 6,300 plant species -- thousands of which are found nowhere else on Earth -- massive blooms of spring wildflowers, and 70 types of scorpion, the Succulent Karoo is a bountiful wilderness.
But the human demands on this place are relentless, from overgrazing by livestock to exotic plant poaching and sand mining. Only a quarter of the desert remains in a pristine state and conservationists are calling for action to research the region, and protect it.

Cobus Theron, of South Africa's Endangered Wildlife Trust (EWT), says the situation is urgent. "It's not adequately protected and the race is to try and get more land under formal protection," he says.
Theron explains that it can be hard to get the public to understand that a seemingly barren desert can be a valuable ecosystem in need of safeguarding. "While this environment looks odd and harsh, it's actually very fragile," he adds.
Unusually for a desert, the Succulent Karoo's has an abundance of plants -- including a third of the world's succulent species. Succulents -- which include cacti and aloe plants -- can survive searing temperatures by storing any moisture in their stems and leaves. Fleshy and peppered with bright flowers, they supply essential food and moisture for the wealth of insects in the Succulent Karoo, such as monkey beetles, termites and long-tongued flies.
In turn, these insects draw insect-eating animals into the desert, like scorpions and golden moles. Several kinds of tortoises, birds and lizards in the Succulent Karoo are unique to this region.
In the springtime the Karoo plants burst into color -- a phenomenon that draws flocks of tourists every year. But this abundance can also attract the wrong sort of attention.
When you hear the words "illegal wildlife trade" rhinos or tigers may spring to mind, but a growing illegal market for succulents is fueling poaching activities in the Karoo region, says Marienne De Villiers, an ecologist for the South African government's conservation organization, CapeNature.
In 2015, CapeNature officials caught a couple who had illegally collected more than 2,200 plants near Knersvlakte Nature Reserve. De Villiers notes that scorpions, baboon spiders, and some lizard species also fall prey to poachers in the region.
