Tiny Seychelles island coaxes bird back from brink

Climate change linked heatwave caused mass starvation of seabirds
Washington (AFP) Jan 15, 2020 - Around a million North Pacific seabirds known as common murres died during a 2015-16 heatwave that disrupted their food supply, scientists said Wednesday, the biggest mass mortality event ever recorded among avian species.

Julia Parrish, an ecologist at the University of Washington and co-author of a paper on the subject published in the journal PLOS ONE told AFP that the increased frequency of such heatwaves appeared to be "relatively new" and linked to climate change.

From 2014 through 2016, an enormous mass of warm seawater nicknamed the "blob" was joined by a strong El Nino, with the two combining to create a marine heatwave stretching from California to Alaska.

El Nino is an irregularly occurring global climate phenomenon associated with warm waters developing in the central and east equatorial Pacific.

During the period from summer 2015 to spring 2016, around 62,000 emaciated murres washed ashore dead or dying along the North American Pacific coastline -- in Alaska alone the rate of die-off was a thousand times higher than normal.

Since only a tiny fraction of birds that die was ashore on areas that are accessible, they estimated the total amount of deaths was between half a million to 1.2 million.

By comparison, 30,000 bird carcasses were recovered after the Exxon Valdez oil tanker spill off the Alaskan coast in 1989, leading to overall death estimates of 300,000 to 600,000, said John Piatt, a research biologist at the US Geological Survey's Alaska Science Center and the paper's lead author.

- How it happened -

Parrish said the effects of the heatwave were two-fold. First, elevated temperatures reduced the quality and quantity of phytoplankton, which in turn reduced the quantity and quality of the fish eaten by common murres -- prey like herring, sardines and anchovies.

Second, as waters warmed, it increased the energy requirements of larger fish like salmon and Pacific cod, that have the same prey as the murres, foot-long birds with black and white bellies that are fast flyers and adept at diving at depths up to 200 meters below the water's surface to forage.

Piatt added that the murres' evolutionary "Achilles heel" was their need to consume half of their body mass every day.

"Everything they do depends on that breast muscle. And when they can't eat three or four days, they burn up all that muscle," and can no longer fly or dive, he told AFP.

Compounding the problem, many of the birds that died were of breeding-age. Murre breeding colonies across the entire region failed to produce chicks for years during and after the heat wave event, the study found.

Several other species experienced mass die-offs during the same period, including tufted puffins, Cassin's auklets, sea lions and baleen whales.

But the common murre die-off was by far the largest recorded by all metrics -- overall number, duration and geographic extent -- the area affected was equivalent in size to Canada.

Taken together, the mass mortalities demonstrate that "a warmer ocean world is a very different environment and a very different coastal ecosystem for many marine species," said Parrish, with sea birds, as highly visible members of that system, "bellwethers of that change."

Giant tortoises amble across Cousin Island as rare birds flit above.

The scene attests to a stunning success for BirdLife International, a conservation group that bought the tiny Seychelles isle in 1968 to save a songbird from extinction.

Thick vegetation smothers ruins that are the only reminder of the coconut and cinnamon plantations that covered the island when the group stepped in to protect the Seychelles Warbler.

Now teeming with flora and fauna and boasting white beaches, Cousin Island is firmly on the tourist map, with managers scrambling to contain visitor numbers and soften their negative environmental impact.

More than 16,000 people visited the island in 2018, compared with 12,000 a decade earlier.

"Tourism is important for Cousin. That's what allows us to finance the conservation projects we run here.

"But 16,000 tourists... that was too much," said Nirmal Shah, director of Nature Seychelles, which is charged with running the special reserve.

Before the island was in private hands, the population of Seychelles Warblers was thought to have shrunk to just 26, barely hanging on in a mangrove swamp after much of their native habitat had been destroyed.

Now, they number more than 3,000 and the greenish-brown bird has been reintroduced to four other islands in the archipelago.

The former plantations have transformed into native forests, teeming with lizards, hermit crabs and seabirds, and the island is the most important nesting site for hawksbill turtles in the western Indian Ocean.

The International Union for Conservation of Nature (IUCN) waxes lyrical about the "unique biodiversity and conservation achievements" of Cousin, "the first island purchased for species conservation", a model since replicated around the world.

- Nature first -

Tourists have been allowed onto the island since 1972, but the message is clear: nature comes first.

In a well-oiled routine, every morning a handful of luxury sailboats and small motorboats anchor off the island, where their occupants wait for Nature Seychelles to skipper them ashore on their boats.

"Tourist boats cannot land directly on the island, the biohazard risk is too big," Shah said.

"Non-indigenous animals who may accidently be on board could come to the island and threaten its (ecological) balance."

Too many tourists can also upset this balance.

Nature Seychelles in July increased the price of visits from 33 to 40 euros ($36 to $44) and removed a free pass for children under 15, resulting in a welcome 10-percent reduction in visitor numbers.

"Something had to be done, there was too much pressure on the environment," said Dailus Laurence, the chief warden of the island.

"When there are too many tourists it can bother nesting birds and turtles who want to come and lay their eggs on the island."

One guide said that some tourists, bothered by the island's ubiquitous mosquitos, would "leave the paths, move away from the group and walk where they are not supposed to", putting fragile habitats at risk.

Shah said that if they wanted to increase the number of tourists, it would require hiring more wardens and guides who live on the island, which would also have a negative impact on nature.

"Our absolute priority is nature, and it comes before tourists. If we have to take more steps to protect it and reduce the number of tourists, we will," he said.

In Seychelles, nature is prized above mass tourism
Anse Bazarca, Seychelles (AFP) Jan 16, 2020 - In a shady patch along a pristine white beach on Mahe Island, a radio spits out reggae and snapper sizzles on the barbecue, as Seychelloise Nareen tops up her rum and coke on time off from her job aboard a luxury yacht.

Her family is spending the weekend at the beach where a couple dipping their feet into the turquoise waters off in the distance are the only foreign tourists in sight.

"We don't have mass tourism in Seychelles, and that's great. That is how we want it," says Nareen, 32, who asked for her full name not to be published.

Nevertheless, like most citizens, she earns her living from tourism, which makes up more than 60 percent of GDP in the Seychelles, the only country in Africa considered "high income" by the World Bank.

The Indian Ocean archipelago, a chain of 115 islands, is a byword for luxury holidays, Instagram-perfect beaches and has gained a reputation as a honeymoon idyll.

But it is confronting a tug-of-war over how to keep the economy growing, while protecting its fragile ecosystem.

"More tourists means it's better for the economy, but it's not the only thing that comes into play," Nareen says.

- One island, one resort -

High-end tourism, from Europe mainly, helped pull the Seychelles from the brink of financial ruin after the 2008 economic crisis.

Visitor numbers almost doubled in the decade that followed, to around 360,000 in 2018, nearly four times the country's population.

But now the Seychelles is grappling with how many visitors it can realistically accommodate. An official study commissioned into the matter is due to begin soon.

In the meantime, the government placed a moratorium in 2015 on the construction of large resorts on the three main islands of Mahe, Praslin and La Digue.

It wanted both to protect the environment and encourage the growth of smaller, locally-run hotels.

On further-flung islands, the Seychelles practises a "one island, one resort" policy.

"It's about controlling the number of tourists that come here, through controlling the number of rooms in the hotels that exist," Tourism Minister Didier Dogley told AFP.

The Seychelles has 6,000 hotel rooms, but another 3,000 are in the pipeline, having been approved before the moratorium took effect, Dogley said.

"We believe that we can go up to 500,000 tourists, that is just an estimate for the time being," he said.

- World heritage -

Nearly half of the Seychelles 455 square kilometres (176 square miles) are classed as protected areas.

By later this year, 30 percent of its 1.3 million square km of marine territory will have protected status too, under a special arrangement in which conservation groups agree in return to pay a small portion of Seychelles' national debt.

The country has two UNESCO world heritage sites: the Mai Valley and its indigenous coco de mer palm trees, and the Aldabra Atoll, home to the Seychelles' famed giant tortoises.

With a few exceptions such as the popular Beau Vallon Beach on Mahe or Anse Source d'Argent on La Digue, regularly named one of the world's most beautiful beaches, tranquility reigns on the islands.

Most beachside resorts keep a low profile, blending into the jungle backdrop that reaches into the island's interior from the white sands bordering the azure shores.

"It all depends on the standards that you want to maintain," said Nirmal Shah, executive director of environmental NGO Nature Seychelles.

He believes that some of the more popular sites have already reached their full capacity.

The Seychelles, he said, "really do not want to become" an eyesore like some beaches in Europe, crowded by umbrellas and edged by concrete.

- Room to improve -

On Grand Police, in the south of Mahe island, locals have been angered by a Gulf company's plans to build a new resort, approved before the 2015 ban.

The project is unpopular over concerns about the health of a local marshland but also because most large resorts are owned by foreign groups.

The government has promised to talk to those behind the new resort to explore how the proposal could be dropped.

Despite environmental pledges and efforts, Dogley said that much still had to be done in Seychelles to ensure a sustainable tourism industry.

Large hotel groups have put measures in place to limit their impact on the environment, such as having their own vegetable gardens and reducing plastic and energy use.

Smaller, Seychellois-owned establishments, though not leaving the same ecological footprint, sometimes lack the resources to match these efforts, despite government incentives.

"Given our small population, the number of tourists is huge, and it is difficult to absorb the footprint of so many visitors," said Shah.

More than a quarter of the workforce is foreign, he pointed out, especially in the tourism and construction industries -- unemployment is only around 3.5 percent.

The tourism industry faces other constraints, too.

The small, hilly country is forced to import more than 90 percent of its goods, and most of the energy needed to keep the islands running is derived from oil-powered generators.

Still, the pursuit of eco-friendly growth over profit alone has struck a chord with some visitors.

"We didn't know much about the ecological side of tourism in the Seychelles... but once here, it really hit us," says Romain Tonda, a 28-year-old French tourist on his honeymoon on Cousin Island, fringed by coral reef.

"It's not perfect, but we can see that it's something that is important for the Seychellois."
