Larch trees are being felled in Goyt Valley in response to an outbreak of Phytophthora Ramorum.
Cutting down is said to be important to help prevent the disease spreading and killing other trees and plants.
Larch trees are known as the worst transmitter of the disease, but sweet chestnut and rhododendron are also included in the plant health notice and will also be removed. The areas affected will be re-planted with tree species that are resilient to the disease.
Timber from the felled trees will be used where possible for construction, fencing materials, pallet wood and biomass.
The work will begin in the next few weeks and is a medium to long-term project. During this time areas of car parking may be closed and rights of way restricted to keep the public safe.
