A SHORTAGE of skilled builders and craftsmen is threatening the survival of the region's historic buildings, a report claims.

The study, by the National Heritage Training Group, found that a lack of tradesmen, such as blacksmiths and carpenters, posed as much a danger to buildings as the ravages of time.

Long-term unfilled vacancies also existed for thatchers, cabinet makers, dry stone wallers and gilders, the report said.

The findings were announced at Chris Topp Wrought Ironworks, near Boroughbridge, in North Yorkshire, which is repairing the main gates to the Houses of Parliament, damaged last year when they were hit by a car.

David Fraser, regional director for English Heritage, said: "Not only does the report produce yet further evidence that heritage conservation skills are at risk, but, uniquely, it puts forward an action plan to tackle specific problems."

The report's findings were supported by a five-year blueprint to save Yorkshire's historic structures, also published yesterday.

As well as detailing measures to tackle the shortage of craftsmen, the Yorkshire Historic Environment Forum plan looks at how its 19 members - including the National Trust and Heritage Lottery Fund - can work together to preserve national treasures such as Harrogate's Royal Hall and the Thornborough Henges, near Masham.

Mr Fraser, forum chairman, said: "A well-cared-for historic environment makes the region a more attractive place for inward investment, provides sustainable housing and office accommodation, earns tourism revenue and provides a tangible sense of who we are in Yorkshire. This document underpins our aspirations in these areas and many more."

The forum has highlighted 13 investment goals, including surveying sites under development pressure and marketing historic tourist attractions.

The blueprint also calls for investment to be focused on restoring grade one and grade two-star listed buildings, especially those in private ownership, industrial buildings and those under threat from development pressure.
