by saying that the national park authority shall attach ‘greater weight to the purpose of conserving....’ rather than the phrase ‘priority must be given’ as used by Sandford and which was more absolute and directly in favour of conservation. Use of the term ‘greater weight’ indicates clearly that evidence must be collected and weighed when deciding where public enjoyment might be considered a less desirable purpose than conservation. The word ‘purpose’ is significant in that it places a legal requirement on the national park authority to consider and demonstrate why it is conserving and enhancing the natural beauty, rather than doing so for no particular reason or simply suggesting an arbitrary priority.
