A white-tailed sea eagle at the Isle of Mull, Scotland, cleanly snatching a fish from the water. White-tailed sea eagles became extinct in Britain in 1916 and the species disappeared from the wild for over 50 years. It wasn't until 1975 that the first formal reintroduction was carried out, with a total of 140 birds returned to the wild over the course of 20 years. These birds have gone on to establish a population of over 80 breeding pairs on the west coast of Scotland. Despite this it is still rare to see the winged hunters showing off their fishing prowess Photograph: David Gibbon/Rex Features

A project to restore tens of thousands of acres of ancient woodland has secured £1.9 million from the Heritage Lottery Fund.

The Big Belly Oak in Wiltshire. Thousands of 'precious' ancient trees could be at risk from pests and diseases such as ash dieback and acute oak decline, experts have warned. Described as the natural equivalent of listed buildings, ancient trees have stood for hundreds of years, watching over historic events and playing a role in folklore and culture. But the majority of the 115,000 ancient, veteran or notable trees registered by the Woodland Trust could be facing the threat of diseases and pests, a loss that would be 'devastating', the conservation charity said. Some, such as the 11-metre girthed Big Belly Oak in Savernake Forest, Wiltshire, which is thought to have stood since the time of William the Conqueror, have acted as significant landmarks for local people for centuries Photograph: Woodland Trust/PA
