In reply to Simon:
been to some of the areas before and after the guide was published...
Baslow coverage is good, been before good soloing/short routes and bouldering the slipstones of the peak (not quite as good obviously). Think the inclusion in the last rock-fax helped but the inclusion of the bouldering is probably already having an affect on making the place popular and spreading the traffic away from trackside! Generally very clean but a bit gritty in some places , haven't been down to the right hand end in the trees for a while so no idea on greenness.
Froggatt woods, had had Downes' crack on the wish list for a while, finally did it in the summer, was clean & pre chalked. Was desperate move onto the final ledge on a sweaty day (not using the tree not shown on the topo) The top out though was very vegetated. Surrounding routes looked extremely green/dirty. Esau's buttress looked in appalling condition. Would require crag cleaning vegetation removal from around the routes, and more traffic (vicious circle as unlikely in current state). Froggatt brook area, Cooked Start & Tinsel's Tangle both excellent, the former maybe worth 2 stars. Bit green still though thought some of the vegetation around the crag could do with a cut back. A great area to visit as we did when the rest of the crag is packed! (indoor Fisherman looks ace, like to try) The boulder problems in the surrounding area starting to get traffic but still green.
Also at Froggatt should small saplings growing on the crag be removed (round jankers area for example), and selective larger trees pruned/removed. (cave crack tree)
Curbar woods again been before the guide was published had hurd about this beauty called "the Line" which is ace, the tree at the bottom will soon start to seriously get in the way of the route and should probably be removed. Short buttress is excellent and the slab climbing probably as good a 3 pebble but less hyped. The soft E1 now HVS in this BMC guide Green Acres is particularly good, but i have reservation to how much traffic the gear placement will take. Other route/boulder problems in the area are fairly clean, a few heathery top outs, again quite a few small saplings or larger birch trees that are already or likely to suffocate routes or cause issues in the future. For the HVS/E1 leader a great area with several good classics and only a few minutes further from the car than chequers buttress.
so in conclusion excellent guide book coverage, great routes/problems, generally clean but some vegetation removal should be carried out
