Cliff cypress returns in Chongqing after extinction in the wild

Cliff cypress returns in Chongqing after extinction in the wild

New Capabilities

A 300-million-year-old conifer declared extinct in 1998 now numbers about 10,000 wild trees, 70% of them in Chongqing

3 days ago: Human Progress reports cliff cypress comeback

Overview

Updated 2 hours ago

The International Union for Conservation of Nature declared the cliff cypress extinct in the wild in 1998. Twenty-eight years later, roughly 10,000 mature trees grow in China's Daba Mountains, and about 70% of them are in Chongqing.

The recovery came from a two-decade effort that pushed cutting-propagation survival from under 20% to above 90% and now produces more than 2 million seedlings a year. The species, nicknamed the 'giant panda of the plant world,' is now a model for pairing endangered-plant conservation with local revenue.

Why it matters

A species declared extinct in the wild now numbers 10,000 trees, showing that targeted propagation and habitat protection can reverse extinction.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

1900-2004

Ginkgo biloba near-extinction (early 20th century)

Ginkgo survived mainly in cultivation by Buddhist monks in China. A 2004 paper suggested supposedly wild populations were actually cultivated, meaning the species may have no truly wild stands left.

Then

Cultivation preserved the species despite its wild decline.

Now

Ginkgo now lines streets worldwide, saved entirely by human propagation.

Why this matters now

Shows that cultivation can preserve a species even when wild populations vanish. The cliff cypress effort goes further by restoring wild populations, not just preserving the species in cultivation.

1941-1948

Dawn redwood rediscovery (1940s)

Metasequoia glyptostroboides was known only from fossils until a living stand was found in central China's Sichuan-Hubei border region. Seeds were collected and distributed to botanical gardens worldwide.

Then

The species went from presumed extinct to widely cultivated within a decade.

Now

Dawn redwoods now grow on every continent, a standard example of a 'living fossil' saved by propagation.

Why this matters now

Like the cliff cypress, a Chinese conifer thought extinct was rediscovered and saved through human propagation. The cliff cypress recovery follows the same playbook at a larger scale.

2026

Glyptostrobus pensilis decline (ongoing)

A related relict conifer, Glyptostrobus pensilis, is still declining. A 2026 study documented a dying micro-population at Nanhua Temple in southern China, with trees at high risk of local extinction.

Then

The Nanhua Temple population continues to decline despite its protected status.

Now

The species remains globally threatened, a contrast to the cliff cypress's recovery.

Why this matters now

Rediscovery alone does not guarantee recovery. The cliff cypress succeeded because of active propagation and reintroduction, not just protection.
