In reply to RockAngel: Interesting. Aussie context, but probably applicable here.
I do think climbers should be wary on asking for dog bans due to conservation purposes. You only have to look at well climbed crag and a poorly climbed crag to understand that climbing has a huge impact on local biodiversity. The amount of fauna and flora is seriously impacted on by climbing. Almost any activity in the outdoors does, it's unavoidable.
If we are going to be so extreme as to ban dogs in the hills for 4 months of the year then I think the climbing community should look out.
I do worry that dog owners in the outdoors are not represented, the BMC, understandably, doesn't take account of dog owners who are members really.
The CRoW act was a terrible piece of legislation for dog owners, done in London with little idea of what it's like on the hills.
