Fortunate enough to visit 40 years ago when we had a breeding pair and several immature eagles in the area. Also plenty of Ring Ouzels, Pied Flycatchers etc... Perhaps its the rose tinted specs but I remember Riggindale as being far more wild back then with the remains of sheep and dead lambs being relatively common. In recent years it appears the area has changed from hill farming to an outdoor activity centre. Very sad news if as suspected the Golden Eagle is now extinct in England.
As someone who lives on the edge of the Lakes your post strikes a note.
There is a lot of good work being done on the fringes Just locally a new wetland has been created, as well as a mini Foulshaw Moss raised bog habitat.There has been a notable increase of trees being planted on the fells.
Only a few miles away Foulshaw Moss has been improved dramatically and the Ospreys are breeding here regularly.
I know of several fringe valleys where the thronging masses never visit .There are great examples of rewilding or the habitats are still in tact already.I don't advertise them, as enough places have been ruined already.
I seldom if ever venture beyond the fringes as so many places in the heart of the Lakes are overrun with fell runners,fell walkers,dog walkers,outdoor pursuit groups,Army training parties,endless lines of school parties and mountain bikers.
The Open Spaces Society and other busy bodies have a lot to answer for.
They resist any attempt to fence off some areas on the fells as they want to be able to roam wherever they like.
I know this because they are constantly blathering on in the local press, objecting to schemes to fence off and rewild.
When I have suggested fencing off even small areas Natural England tell me it would be more hassle than it is worth.
Compare this with my visit to the Porto Conte Natural Park in Sardinia last year.Huge areas had been fenced off,the habitats were being managed and the birdlife was overwhelming.
Even Lanzarote is ahead of the game.They control entry and exit into the Timfanya National Park and only accredited coaches are allowed to proceed through the volcano route.Even then the passengers are not allowed to hop on and off then wander around willy-nilly.
Try to impose restrictions like that,in the Lakes and just wait for the wailing and gnashing of teeth to begin!
