NATURE’S WAY BLACKTHORN

EDGEROWS ARE a quintessential part of the British DARK H countryside and a vital habitat for our wildlife. In fact, it is estimated that 1,500 of inhabit hedgerows at some point in their life cycles. Many hedgerows have been around for hundreds of years, providing a constant material source of safety and food for numerous generations of wild . The blackthorn has negative Hedgerows which have been in existence since before the Enclosure connotations in our folklore Acts in the 18th and 19th centuries are regarded as ‘ancient’, and are likely to have but plays a vital role for become ‘species-rich’. In Northern England and upland Wales, a hedgerow hedgerow wildlife, says containing four species of woody shrub in a 30m stretch is considered species-rich; David Chapman in the rest of England and Wales five different varieties are needed. During the second half of the 20th century we lost a huge amount of this important habitat – in 1945 there were approximately 500,000 miles of hedges in Britain but by 1990 there were just 107,000 miles left. Most of them were ripped out to make fields bigger, improving agricultural output but removing a vital wildlife environment. Hedgerows are now better protected but are often still neglected. Many now feature tall, straggly trees and large gaps. The tendency is to fill the gaps with fences which are much easier to maintain but are of little value to wildlife. Two trees – blackthorn and hawthorn – are strongly associated with hedgerows.
