Loro Parque has welcomed two critically endangered Sumatran tigers as part of a European conservation breeding programme aimed at helping safeguard one of the world's rarest big cats from extinction.

The new arrivals, Zaza, a two-year-old female, and Lucu, an eight-year-old male, have travelled from separate zoos in the UK to form a breeding pair under the European Association of Zoos and Aquaria (EAZA)'s European Endangered Species Programme (EEP).

Carefully matched for conservation

The pairing has been planned using detailed scientific data rather than chance. Every Sumatran tiger in the European breeding programme has a comprehensive genetic profile, including ancestry, family relationships, health, age and previous transfers.

Programme coordinators use this information to maximise genetic diversity while avoiding inbreeding, helping to maintain a healthy population under human care.

Wolfgang Kiessling, president of Loro Parque, said the arrival of the two tigers strengthens the park's commitment to conserving one of the world's most endangered tiger subspecies.

He said every transfer within the programme is based on strict scientific criteria and highlights the importance of cooperation between modern zoos in protecting species facing an uncertain future in the wild.

Only a few hundred remain

The Sumatran tiger (Panthera tigris sumatrae) is the smallest and darkest of all surviving tiger subspecies, having evolved to live in the dense tropical forests of the Indonesian island of Sumatra.

Conservationists estimate that only 300 to 400 individuals remain in the wild, with habitat destruction, forest fragmentation, human expansion and poaching continuing to drive the population down by around 40 animals every decade.

The urgency is heightened by the fact that the Javan tiger and Bali tiger, two closely related island subspecies, are already extinct.

Long-term commitment

Mike Jordan, the park's zoological director, described the arrival as an important milestone.

He said the priority is to give both animals the time, space and specialist care they need to settle into their new home before any breeding is considered.

Any future offspring will depend on the tigers' welfare, compatibility and continued approval from the European breeding programme.

By joining the EEP, Loro Parque continues to play a role in international efforts to preserve the Sumatran tiger, while giving visitors the opportunity to learn more about one of the world's most threatened and iconic big cats and the importance of protecting the tropical forests on which its survival depends.
