Monkeys to elephants: Life at a Thai wildlife hospital. See pics

Yong, a pig-tailed macaque rescued from a life harvesting coconuts, was being treated at Thailand's only NGO-run wildlife hospital.

He is one of dozens of animals treated each month at the Wildlife Friends Foundation Thailand (WFFT) facility.

Patients range from delicate sugar gliders intended as pets, to some of the hefty rescued elephants that roam WFFT's expansive facility in Phetchaburi, southwest of Bangkok.

The wide variety can be a challenge, said vet Siriporn Tippol.

"If we can't find the right equipment, we have to DIY use what we already have or modify based on the specifications we need."

She described strapping an extension handle onto a laryngoscope designed for cats and dogs so it could be used during surgery on bears and tigers.

Yong was in quarantine after rescue -- coconut monkeys often carry tuberculosis or other infectious diseases -- and needed a full health check.

But first, he had to be sedated, with a tranquilliser dart blown from a white tube into his left haunch.

Before long he was slumped over and ready to be carried to hospital.

Blood was taken, an IV line placed and then it was X-ray time, to look for signs of broken bones or respiratory illness.

Next was a symbolic moment: vets cut off the metal rings around the monkey's neck that once kept him connected to a chain.

The operating theatre was the final stop, for a vasectomy to allow Yong to join a mixed troop of rescued monkeys without risk of breeding.

- Out-of-hand hobby -
The light-filled hospital only opened this month, replacing a previous "tiny" clinic, said WFFT founder Edwin Wiek.

"I've always dreamed about having a proper medical facility," he told AFP, over the sound of nearby tigers roaring in grassy enclosures.

With over 900 animals in WFFT's care and a regular stream of emergency arrivals, "we needed really a bigger place, more surgery rooms, a treatment room," he said.

Wiek founded WFFT in 2001 with two macaques and a gibbon. It now spans 120 hectares (297 acres) and houses 60 species.

"That hobby got out of hand," he laughed.

He has long advocated for stronger wildlife protections in a country well-known as a wildlife trafficking hub in part because of its location and strong transport links.

Wiek once had tendentious relations with Thai authorities, even facing legal action, but more recently has become a government advisor.

WFFT is now a force multiplier for the Department of National Parks, Wildlife and Plant Conservation (DNP).

"In many cases, when wild animals from elephants and tigers to macaques are found injured and displaced, we coordinate with WFFT, who assist in rehabilitation and medical care," said DNP wildlife conservation director Chalerm Poommai.

One of WFFT's current campaigns focuses on the estimated thousands of monkeys like Yong trained to pick coconuts on plantations in southern Thailand.

"The animal welfare issue is horrible," said Wiek.

"But another very important point is that these animals actually are taken out of the wild illegally. And that, of course, has a huge impact, negative impact on the survival of the species."

WFFT is working with authorities, the coconut industry and exporters to encourage farmers to stop using monkeys, and switch to shorter trees that are easier to harvest.

There is also work to do in equipping the new hospital. A mobile X-ray unit and specialised blood analysis machine are on Siriporn's wishlist.

And Wiek is thinking ahead to his next dream: a forensics lab to trace the origins of the animals confiscated from traffickers.

"The laws are there, we lack the enforcement," he said.

"But with this tool, we could actually do some real damage to these illegal wildlife traffickers."
