NATIONAL park chiefs are hoping the organisation's 50th anniversary next year will prove to be the catalyst that ensures its future survival.

Research indicates that the majority of people who make regular trips to the Yorkshire Dales are white, able-bodied, middle-aged and middle class.

A report warns if no attempt is made to promote the Dales' attractions to a more diverse audience, there is a real risk future generations will grow up without appreciating the great outdoors.

The report was compiled by the parks authority's acting head of internal affairs, Andrew Osbourne.

He said: "One of the conclusions which can be drawn is that the national park is becoming less relevant to younger people.

"Looking to the future, this could have a range of impacts on the national park. If new audiences are not made aware of the national parks, then there will be a public decline in the support for their conservation and enhancement.

"Further, the long-term future of tourism and associated businesses could well be weakened."

The report, which was presented to the national park authority last week, suggests that during next year's 50th anniversary in celebrations it should take its message into the inner cities, to schools, to shows and festivals while a number of new marketing initiatives are developed to improve the profile of the Dales.

Members were reminded of the role local communities play in making the Yorkshire landscape what it is today, and events planned in 2004 should also celebrate their contribution.

At last week's meeting the authority sanctioned a working group which will be responsible for spearheading new schemes to come under the 50th anniversary umbrella.

Mr Osbourne said: "While pursuing this new area of work and reaching out, the authority will be mindful of its traditional audiences and an integrated programme of initiatives will be developed for residents and current visitors."
