The point of these bolt belays is not for trad climbers, it's to make it simpler to set top ropes up above Wee Doris and Cabbage.Any trad climber would sort a belay and you can walk off anyway.
Andy could you amend this to just having a general discussion by the Area on what, if anything, should be done about routes at Stoney for which now dead ash trees provide the belay (and potentially abseil retreat) where no other suitable natural anchors exist. If the Area would like bolted belay / ab stations (not lower offs) to replace the trees then PBF are willing to do the work.
If ALL the trees do disappear, I think placing a few new pegs should be considered before bolting. As I said above, the dieback is unlikely to be permanent on the timescale that bolts are permanent. Many of the routes already have legacy pegs; generally none have bolts. Bolting blank rock on trad crags should be an absolute last resort.
especially where there were none previously
they can fail very suddenly and without any warning
far more retrograde than a bolted belay/
