Those who like to go walking
in the Yorkshire Dales must take care to ensure their dogs are under control, the National Park Authority has said.
People bringing their four-legged friends with them when they don their hiking boots
have been asked to consider nesting birds in the area, with many nests full of eggs that are vulnerable to disturbance from pets.
Such birds include skylarks, lapwings, red grouse, oystercatchers and curlews.
Ranger services manager Alan Hulme said areas where birds could nest safely without humans or dogs showing up are now more accessible under the Countryside and Rights of Way Act in 2005.
For this reason, the authority is looking to "highlight" the potential problems, he stated.
"Disturbance can mean that adult birds flee the nest, leaving eggs to get cold or, later, leaving newly-born hatchlings exposed to the elements and to predators," Mr Hulme added.
There are several times in the year when dog owners need to keep their pets on a lead when on the hills, such as early spring when the lambing season is in full swing.
