The 100 Asian elephants, which were on Saturday pictured crossing the Mall in London, were created by communities in the southern Indian state of Tamil Nadu who live in close proximity to the large mammals.

Actress Joanna Lumley, Bollywood star Amy Jackson and presenter Donna Air posed for pictures to promote the installation.

The models were positioned by conservation group Elephant Family as part of the CoExistence campaign, a response to "the increasing overlap between the human and animal world, which is in part responsible for the spread of deadly zoonotic diseases".

Following the parade in the Mall, the elephants will be displayed in various London locations before going on sale for between PS6,000 ($A11,000) for a calf and PS30,000 ($A54,000) for a fully grown tusker.

Gurkha guards will look after the sculptures as they are transported to destinations including the King's Road and Royal Parks this summer.

Each model is made from lantana, an invasive weed whose removal from protected areas benefits wildlife and the herd is joined by a flock of extinct or endangered model British birds such as the nightingale, curlew, Dalmatian pelican and turtle dove, highlighting the biodiversity lost in the UK in recent years.

All proceeds will go to the work of Elephant Family, including the secureing of wildlife corridors to enable safe movement for animals and people, the expansion of national parks and the protection of indigenous and tribal knowledge.

Lumley, a long-standing ambassador of Elephant Family, said: "The elephants crossing London's Mall are as mighty as they are meaningful, and I am proud to represent this campaign.

"The herd has arrived at the time of a great pause, when our human footprint on the wild world has lessened and wildlife everywhere has flourished.

"These elephants carry with them inspiring stories of coexistence and we have much to learn from them."

Fellow ambassador Jackson said: "Following The Mall, these elephants will continue to make their way around the globe on their 13,000-mile migration.

"As they reach new places they will tell the story of our crowded planet, the effect of our human footprint on wild spaces and share inspiring ways we can coexist with all living beings that make our world magical - from tigers and badgers to nightingales and elephants."
