Hedgehog and House Sparrows have been included on an updated list of species and habitats which need protection.
The new Biodiversity Action Plan (BAP) has seen an increase in the listed species from 577 to 1,149 species being in need of conservation and greater protection. 59 species of bird are included which is 1 in 5 of all species regularly occuring in the UK.
A separate study also highlighted the decline in the UK's hedgehog population. The study by the University of London for the People's Trust for Endangered Species and the British Hedgehog Preservation Society listed tidier gardens and urbanisation as key factors affecting the fall in the number of the small mammals.
