Trees as indicators of hedgerow age

Mature trees commonly found in hedgerows can provide a good judge of hedgerow age, by finding out the age of the trees themselves. This can be done easily with dead tree stumps, such as those provided by the pathogen Ophiostoma ulmi (dutch elm disease), especially in the southern areas, as well as hurricane damage, by counting the growth rings of the stumps.

Species composition of hedgerows and verges have an infinite variety where not only are no 2 the same, but they are different every 100 yards or sometimes every few yards.
