A PLEA has gone out for walkers and tourists to protect rare birds and toads around an East Lancashire beauty spot.

Warning signs are being placed around Coldwell Reservoir at Southfield, between Colne and Nelson, urging people not to stray too far from the beaten track.

Gates are also now being locked around the site at night as the result of people straying too far from recognised pathways.

The reservoir, owned by United Utilities, is a Biological Heritage Site and is home to a number of protected species.

Tufted ducks, a rare Lancashire breeder, and snipes, curlews and short and long-eared owls are also known to nest locally.

Extra signs are also being erected to alert people that toads, another frequent visitor, are also breeding at this time of year.

Paul White, an assistant land agent for United Utilities, said: "It is vital that the whole community works together to help preserve these species, which are such an asset to this beautiful area."

Plant species present there include the grass-of-Parnassus and Coldwell is the only site in the East Lancashire area where this can be found. Sneezeworth and smooth lady's mantle are also found there.

Mr White added: "Grasses are now beginning to come through and as the breeding season is underway it is important to bring in these measures."

The company's estates department has pledged to work with police and Lancashire Wildlife Trust to ensure that people do not affect wildlife.
