Be aware that the 1:25k's are 50 years out of date. Even Yahoo! is 5 years(?) old. It's surprising how quickly hedgerows disappear, or in recent times, appear. Also I think you've missed a couple where they disappear under the labeling on the 1:25k. > By using both sources the field boundaries have been largely completed in > this area.

I notice you tagged some areas as forest when they're labeled as woods on the 1:25k. I also think that labeling any wood in the UK as natural is incorrect, but I'll put that forward for discussion in a separate thread...
