The British and Irish Association of Zoos and Aquariums (Biaza) have expressed concern that Brexit will negatively impact EU-wide animal breeding programmes.
All EU Member States sign up to the same high standards of health and welfare for zoo animals. This is essential for zoos who frequently move animals across the EU for breeding purposes.
Catherine Bearder MEP, who founded the cross-party MEPs for Wildlife group said:
"Animal breeding programmes in the UK may suffer outside the EU with its regulations and safeguards, which bring cooperation and funding.
"Protecting genetic diversity needs cooperation and ease of movement."
