“If I had the choice I would group by valleys - or catchments”
I agree, but without getting bogged down into flora I suggest we define the limit of Anglezarke as :-
West - Stronstrey Bank escarpment
East - A675 to the East ( as it runs along the “valley” bottom betweem Turton & Anglezarke Moors)
South - The road from Belmont to Rivington village (as it runs at the base of Rivington Moor escarpment)
North - Dean Black Brook. (Separating Anglezarke from Wheelton Moor)
This is a large area to survey comprehensively and as you know, features are “popping” out of the peat daily.
