ZSL launches national native oyster quest to find forgotten British treasure

Wildlife photographers across the UK are being challenged to capture underwater images of the rare European native oyster (Ostrea edulis), as international conservation charity ZSL (Zoological Society of London) launches a national native oyster hunt to galvanise support for the species.

Suffering a 95% decline in population over the last 200 years due to historic overfishing, habitat loss, pollution and the introduction of diseases – images of the species in their natural habitat on the seabed are very rare.

Now ZSL, who run the National Native Oyster Network jointly with the University of Portsmouth (UoP) are calling on the British and Irish public to help them gather visuals of the iconic native species.

Project managers hope that images and video generated through the competition will help to answer questions around the oysters’ recovery, including revealing if there are indeed any oyster reefs left and whether other endangered species like the spiny seahorse (Hippocampus histrix) or European eel (Anguilla anguilla) are associated with the habitat. The images will also be used by oyster conservationists to promote the importance of the humble mollusc.

Left undisturbed, oysters will settle on top of one another forming a 3-dimensional reef structure. Much like coral reef ecosystems in tropical seas, or trees in a forest, oysters grow a habitat in which other species thrive – creating marine mega cities in the form of an oyster reef. However, none are currently known to still exist in the UK and Ireland. 

Judged by a panel of professional photographers; Tom Gilks, Picture Editor at BBC Wildlife Magazine, Tom Mason, professional wildlife photographer and Nikon Europe Optics Ambassador and oyster expert Dr Philine zu Ermgassen of the European Native Oyster Restoration Alliance (NORA) – the competition will run from 1st March through to 31st of September  with the winners announced on December 1st 2020.

The winner will win a one-day advanced photography workshop hosted at ZSL with professional photographer and National Geographic Explorer, Dave Stevenson and a BSAC (British Sub-Aqua Club) diving membership including access to UK-wide training, a monthly magazine, insurance cover and discounts on dive holidays, kindly donated by BSAC. Runner-up prizes include a BSAC membership and a £100 voucher towards completing any PADI training also generously donated by the Oyster Diving Company, the UK’s premier PADI scuba diving and travel company.

Alison Debney, ZSL’s Senior Conservation Programme Manager said: “Throughout our restoration work – one of the barriers we’ve come up against is not having images of native oysters in the wild. Trying to explain the importance of a species to people when they’re only ever framed as a seafood dish – can be a struggle.

“Oysters provide enormous benefits in the form of ecosystem services; nurseries for wildlife, clean water and in abundance, removal of carbon from our environment into their shell to name a few. Whether you’re a diver, photographer, fisher or simply live near a coast – we need your help. The native oyster is a forgotten British treasure that needs the public’s support during this long road to recovery.”

Celine Gamble, ZSL’s Native Oyster Network Coordinator said: “Oysters are an essential part of coastal communities around the UK, helping to sustain them through means of a livelihood. Outside of these hubs however, very little is known about them. Our work would be halfway done if everyone could tell the difference between the pacific non-native oyster and our native oyster. We can’t simply let another vital British native species slip away.”

Marine Biologist and network co-founder Dr Joanne Preston based at UoP’s Institute of Marine Sciences said: “We desperately need to revive the lost cultural memory of our native oyster habitat – and what better way to do that then get the nation involved in a quest to find, document and celebrate the remnant oyster reefs in our coastal waters.”

The oyster restoration work is part of ZSL’s Mother Thames campaign, celebrating the incredible variety of life below the surface of the River Thames – which will culminate in the publication of the first-ever State of the Thames Report this summer.  To learn more about the work please visit: www.zsl.org/motherthames
