The trouble is that many indicators - such as those two - are very
unreliable. SOME are reliable, such as rhododendron woods or wild
juniper, but most have exceptions.

Oaks will grow even on moderately alkaline soil, so you have to
be able to tell natural woods from plantations or outliers. And
nettles are phosphate lovers, so are found where stock used to
be kept (and next to drove roads), even on poor soil.
