Ten different plants should be used, including honeysuckle, elm, hawthorn, dogwood and blackthorn.
This trail has been around for 27 years and runs from Forde Abbey in the west, across Dorset to Bokerley Dyke in the east. However, the group also hopes to plant other hedges along four small hiking trails in the county.
About 50 volunteers have already signed up to help the Dorset Climate Action Network (Dorset CAN) carry out the long-term project, which is still in its infancy and could take ‘a generation’ to complete, according to The Telegraph .
The first of four stages involves volunteers walking the Jubilee Trail and surveying a 1.8-mile (3 km) stretch to see if there are any holes in the hedges.
“We are focused on what we can do now to engage people to help improve existing hedgerows and possibly create new plantings where appropriate,” Dorset CAN Land Use team coordinator Julie Leah told the Telegraph.
“Each kilometer takes a good half hour [to survey] because you must identify the plant species, the condition of the hedges and the approximate measurements.
“Most volunteers will need training in one or all of these aspects. We aim to do a lot of this via online resources. The Jubilee Trail alone is 100 miles (161 km).
