Ash trees suffering from dieback

One of the biggest issues facing our nature reserves is the ongoing management of Ash trees suffering from dieback – Augill is no different as the woodland there is about 10% Ash. Some of the ash trees were identified through our tree safety surveys as being diseased and close to footpaths and the car park.

Two of the diseased trees were overhanging the Augill Smelt Mill. Any limb shedding would cause further damage to this structure, which is on the Historic England Scheduled Monument At-Risk register.

We made the decision to employ a local firm of tree surgeons to remove both these trees and several other ash trees around the car park. This work was delivered working with our tenant for the reserve; Cumbria Wildlife Trust.

An ash tree trunk with no branches and left as a monolith

This tree was left as a 5m tall ‘monolith‘, which as continues to decay, will provide habitat for birds and bats.

The trees were removed in Mid-January and I went recently to check on their progress. When I arrived they had cordoned off the car park and footpaths and had their climber in the larger of the two trees removing the higher limbs. By the time I left about 2 hours later, they had removed the majority of the limbs, while the ground crew had processed the brash and timber into log piles and brash windrows

The grassland at Augill Pasture is managed by grazing and unusually for our reserves it is grazed by ponies. Two small ponies were put on the reserve in October and were taken off recently, as the weather became very cold at the beginning of January. This grazing will have controlled the growth of the grass species, allowing the forb species enough space to grow as the weather turns warmer.
