Endangered black rhinos return to Tanzania

Two endangered black rhino have been returned to their native habitat from Port Lympne Wild Animal Park in Kent, UK by The John Aspinall Foundation, a UK-based charity devoted to saving rare and endangered species and reintroducing them into protected areas in the wild.

Laikipia, a female and Limpopo, a male, both five years old, were born and raised at Howletts and Port Lympne Wild Animal Parks in Kent which are managed by The John Aspinall Foundation. The two animals were flown on a specially-chartered cargo flight to a reserve on the western edge of the Serengeti National Park on 11 June. They arrived safely the following day.
Both animals have taken to their new surroundings very quickly and by the end of the first day in Tanzania, Limpopo had taken his first steps outside the ‘boma’, similar to a stable.
Over the last few days since arrival, the rhino have both been introduced to their outside paddocks which allows them the chance to get used to their new surroundings as well as giving the rhino teams the opportunity to monitor the animals. The progress of their return to the wild will be slow but steady and if things proceed as planned, they will be released into larger paddocks soon.
The reintroduction was approved by the Convention on International Trade in Endangered Species (CITES) and the Department of Environment, Food and Rural Affairs (DEFRA).
