The south Devonshire seaside town of Torbay is to become the first local authority in the UK to put an economic value on every one of its 28,000 trees. Using software developed by the US forest service, the town has surveyed its tree cover and calculated the benefit it brings in terms of pollution being removed from the air and energy saved due to summer shade and slower heat loss in the winter. A similar survey, in New York found that every $1 spent on tree planting brought benefits worth $5.6.
Several years ago, American researchers identified the value of woodlands in flood prevention and water purification. I’ve often wondered what role the woodlands around Loch Ness play in helping to reduce the chance of flooding when heavy rain falls on the surrounding hills. Woodlands can help slow the speed at which rain landing in the surrounding area, flows into the Loch. They can act as a natural flood defence.
Will this continue to change the way we think about the tress and forests around Loch Ness? While many trees were planted with the aim of producing timber, the Loch’s woodlands are providing a natural habitat for wildlife, a first class recreational resource, they are helping to absorb and store carbon and they could be helping to reduce flooding and provide shelter. Loch Ness trees it would seem are quite a valuable resource. One member of destination Loch Ness converted a 90 acre livestock farm into native woodlands which would more than offset their Loch Ness self catering business carbon emissions for many years.
