Sections of the woodland at Beacon Fell Country Park are to be thinned in order to improve the quality and diversity of the habitat.
The work will be carried out under a felling licence issued by the Forestry Commission. It will be the first of several operations set out in a new management plan, with thinning being carried out approximately every five years.
The work a is due to start at the end of this month.
Marcus Johnstone, county council’s cabinet member for environment, planning and cultural services, said: “While visitors may be concerned about the initial impact and the disruption, the long-term benefits will be a woodland that is better for wildlife and visitors.
“The work will be carried out by contractors in accordance with instructions from the county council’s forestry experts.
“If the work causes any damage to the footpaths, the repairs will be carried out once the felling has been completed.
“Anyone who has any queries about the work can contact the Ranger Service on 01995 61693.”
