Don't know the job but do know where it is. Others will be in a better place to comment.
It's not a big grouse area, but I would expect they do some burning, pred control and would like some walked up days, certainly not a driven moor. Red , Roe & Sika in the area, some nice ground and a few Boar kicking about! Not sure on the pheasants, the ground is certainly tough for them but will show some cracking birds, I would suspect.
Not 100% on the ownership [so won't say anything] , anytime, I drive past the buildings etc are neat and tidy and look to have had money spent [allways a good sign].
I haven't heard anything negative about the place, so if anyones interested, apply! It's the only way to find out.
