Early cold snap a threat to Britain’s native species

Native species of Britain, such as harvest mice, could be plunged into crisis if the early cold snap sweeping the country continues for much longer, experts warned.

Chester Zoo’s biodiversity officers fear harvest mice could see their numbers drop by 95 per cent in harsh weather over the winter.

Other smaller, fragile species such as wrens and goldcrests could also face hardship if the current cold weather continues.

The zoo’s Sarah Bird said: “Harvest mice, in particular, will struggle if this goes on for very much longer.

“Frozen ground can also make it difficult for species that have to dig for food, such as moles.

“This weather will particularly affect small or weak individuals of any species as they will find it more difficult to find food and keep warm.”

One benefit of the snow is that it makes it much easier to spot wildlife, Ms Bird added.

“It is well worth watching out for unusual birds feeding in trees with berries or at bird feeders,” she said.

“This year there have already been a lot of waxwings seen across the UK, which have come here from Eastern Europe and Siberia.”

The zoo has also given its top tips for caring for native species over the winter months, including:

Feeding birds with seeds, fat balls and fruit can also help other wildlife including mammals. Food should be provided in feeders, on bird tables and on the ground.

Providing water is extremely important when the temperature is below ze­ro. Make sure a shallow water container is ice free for at least part of the day.

Trees and shrubs with berries are a very festive sight in the frost and snow, but it is worth remembering that they are also very important food for wildlife, so always leave plenty if you collect any from your garden.
