The number of endangered animals in the UK has doubled over the past 10 years, according to wildlife experts.

Hedgehogs, house sparrows and harvest mice are among the 1,149 species that have been identified as being under threat and in need of help to survive.

Hundreds of wildlife experts spent more than two years working out which species need the most protection.

The government-approved list is aimed at increasing awareness of conservation and the animals and habitats at risk.

Some animals featured on the first list, in 1997, have already benefited from the conservation efforts made since then.

The numbers of 123 animals and species, including the ladybird spider and lady's slipper orchid, have increased enough to get them taken off the latest list.
