Invasion of the orchid snatchers

Ruthless hunters track their prey around the globe, snatching stunning individuals from their homes before they can even be named.

The beauties only surface in the shadiest of nurseries and high prices for their lives are agreed under the counter by hungry-eyed collectors.

This is not the plot from a harrowing tale of people smuggling but the fate of rare and highly prized orchids.

The plants have inspired frenzied collection since the 18th century with their lustrous blooms and incredible variety.

Now, scientists say the illegal collection of orchids is pushing species to the edge of extinction, with dire consequences for biodiversity.

With some vulnerable species available on the black market before they can even be formally named, biologists and customs officers alike are battling to preserve the captivating plants.
Sex appeal

Admired for their beauty, orchids make up the largest family of flowering plants (Orchidaceae) with over 26,000 species.

The plants vary enormously from tiny 3-4mm Bulbophyllum minutissimum to 20m long vanillas: lianas that grow high up in rainforest.

What unites them is the unique way they germinate from seeds, developing a tuberous mass of cells to form a seedling plant.

For orchid admirers however it is the sensual differences between the plants that inspire such admiration and many are driven wild by the unique shape, scent and sight of new species.

Victorian Britons referred to the condition as "orchidelerium", an insatiable lust for collecting the plants.

From delicate ghost orchids to the beautifully coloured petals of Cattleya, the aesthetic appeal of orchids is obvious.

Orchids: The bigger picture

Orchids are often referred to as indicators of a healthy eco-system
This is because many species are highly sensitive to disturbance
Orchids can only germinate due to their symbiotic relationship with a microscopic fungus so soil must be stable for them to grow

The plants also interact closely with invertebrates
Bee orchids (Ophrys) are named because their labellums mimic the appearance and scent of female bees, attracting males that then spread their pollen

Throughout history the plants have been considered "overtly sexual" with voluptuous blooms sporting enlarged lips (labellum): pouting platforms to entice insect pollinators.

But the individuality and appeal of orchids also makes them vulnerable.

"Orchids are naturally rare with many species only being known from a handful of populations," says orchid expert Dr David Roberts from the Durrell Institute of Conservation and Ecology at the University of Kent, UK.

"Smuggling only affects the groups that are specifically in demand which isn't all orchids. However for the groups that are sought after, such as slipper orchids, it is a big problem."
High price

Rare species can fetch a pretty penny; a single stem of the Rotchschild's Orchid (Paphiopedilum rothschildianum), known as the Gold of Kinabalu, is reported to command prices of around $5000.

After its discovery in 1987 this slipper orchid, remarkable for its imposing horizontal petals, was stripped from the wild by orchid smugglers bringing it close to extinction.

Despite reintroduction of the plant from cultivated seedlings, it is still described as endangered and its few known wild locations in Kinabalu National Park in Sabah, Malaysia are kept a closely guarded secret.

However, not all species are afforded the same protection.

Orchids are naturally rare with many species only being known from a handful of populations”

Dr David Roberts Durrell Institute of Conservation and Ecology

Last year, Asian orchid expert Dr Jaap J Vermeulen studied an orchid collected by conservationists in a national park in Sarawak, Malaysia.

But before he could describe the new species to science, it had been introduced to the black market.

"Bulbophyllum kubahense is a particularly beautiful species with a dense [cluster] of fairly large, white, heavily purple spotted flowers. That makes it desirable to orchid growers," Dr Vermeulen explains.

"Traders found the species in a conservation area, and first thought that is was a particularly luxuriant form of another, similar looking species... Plants appeared in nurseries in Sarawak, Singapore and Thailand."

Through his analysis, published in the journal Plant Systematics and Evolution, Dr Vermeulen confirmed that the plant was a "true novelty".

"It is beautiful, and it is rare: only known from a single locality near Kuching, Sarawak. That will put the price up, and with it the collecting pressure on the natural population," he warns.
Populations stripped

This is not the first time an orchid has been endangered before it has even been formally described.

Such is the demand from collectors, smugglers scour the globe for new species of orchid, sometimes removing whole populations of plants before anyone else knows of their existence.

Dr Vermeulen cites examples from peninsular Malaysia and Vietnam but the most famous example comes from Peru.

Phragmipedium kovachii was first found in 2001 and is referred to as one of the most important natural history discoveries of the last decade.

A foot tall with striking purple blooms, it is a distinctive member of the lady's slipper family, named for their slipper-shaped petal pouches.

Orchid dealer James Kovach bought the orchid from a roadside vendor in Peru and travelled back to his native US with it.

Within days, the Peruvian authorities asked the US Fish and Wildlife Service to investigate the plant, as all Phragmipedium are banned from export under the Convention on International Trade in Endangered Species (CITES).
