Rising seas threaten limited habitat of giant Indonesian lizards, say compilers of 'Red List'

MARSEILLE, France: Trapped on island habitats made smaller by rising seas, the Komodo dragon of Indonesia was officially listed as “endangered” on Saturday, in an update of the authoritative wildlife Red List.

Overfishing also threatens nearly two in five sharks with extinction, the International Union for the Conservation of Nature (IUCN) said.

About 28% of the 138,000 species assessed by the International Union for the Conservation of Nature (IUCN) for its survival watchlist are now at risk of vanishing in the wild forever, as the destructive impact of human activity on the natural world deepens.

But the latest update of the Red List for Threatened Species also highlights the potential for restoration, with four commercially fished tuna species pulling back from a slide toward extinction after a decade of efforts to curb overexploitation.

The most spectacular recovery was seen in the Atlantic bluefin tuna, which leapt from “endangered” across three categories to the safe zone of “least concern”.

The species — a mainstay of high-end sushi in Japan — was last assessed in 2011.

“These Red List assessments demonstrate just how closely our lives and livelihoods are intertwined with biodiversity,” IUCN Director General Bruno Oberle said in a statement.

‘Clarion call’

A key message from the IUCN Congress, taking place in the French city of Marseille, is that disappearing species and the destruction of ecosystems are no less existential threats than global warming.

At the same time, climate change itself is casting a darker shadow than ever before on the futures of many species, particularly endemic animals and plants that live uniquely on small islands or in certain biodiversity hotspots.

Komodo dragons — the world’s largest living lizards — are found only in the World Heritage-listed Komodo National Park and on the neighbouring island of Flores.

The species “is increasingly threatened by the impacts of climate change”, said the IUCN: rising sea levels are expected to shrink its tiny habitat at least 30% over the next 45 years.

Outside of protected areas, the fearsome throwbacks are also rapidly losing ground as humanity’s footprint expands.

“The idea that these prehistoric animals have moved one step closer to extinction due in part to climate change is terrifying,” said Andrew Terry, Conservation Director at the Zoological Society of London.

Their decline is a “clarion call for nature to be placed at the heart of all decision making” at crunch UN climate talks in Glasgow, he added.

‘An alarming rate’

The most comprehensive survey of sharks and rays ever undertaken, meanwhile, revealed that 37% of 1,200 species evaluated are now classified as directly threatened with extinction, falling into one of three categories: “vulnerable”, “endangered” or “critically endangered”.

That’s a third more species at risk than only seven years ago, said Simon Fraser University Professor Nicholas Dulvy, lead author of a study published on Monday underpinning the Red List assessment.

“The conservation status of the group as a whole continues to deteriorate, and overall risk of extinction is rising at an alarming rate,” he told AFP.

Five species of sawfish — whose serated snouts get tangled in cast off fishing gear — and the iconic shortfin mako shark are among those most threatened.

Chondrichthyan fish, a group made up mainly of sharks and rays, “are important to ecosystems, economies and cultures,” Sonja Fordham, president of Shark Advocates International and co-author of the upcoming study, told AFP.

“By not sufficiently limiting catch, we’re jeopardising ocean health and squandering opportunities for sustainable fishing, tourism, traditions and food security in the long term.”

The Food and Agriculture Organization reports some 800,000 tonnes of sharks caught — intentionally or opportunistically — each year, but research suggests the true figure is two to four times greater.

Conservation tracker

The IUCN on Saturday also officially launched its “green status” — the first global standard for assessing species recovery and measuring conservation impacts.

“It makes the invisible work of conservation visible,” Molly Grace, a professor at the University of Oxford and Green Status co-chair, said at a press conference on Saturday.

The new yardstick measures the extent to which species are depleted or recovered compared to their historical population levels, and assesses the effectiveness of past and potential future conservation actions.

Efforts to halt extensive declines in numbers and diversity of animals and plants have largely failed.

In 2019 the UN’s biodiversity experts warned that a million species are on the brink of extinction — raising the spectre that the planet is on the verge of its sixth mass extinction event in 500 million years.

“The red list status shows that we’re on the cusp of the sixth extinction event,” the IUCN’s Head of Red List Unit Craig Hilton-Taylor told AFP.

“If the trends carry on going upward at that rate, we’ll be facing a major crisis soon.”
