Wikipedia's own Moorland article states plainly that experts disagree on the exact distinction between heath and moorland: moor is generally described as highland, high-rainfall ground while heath is lowland and more often shaped by human activity, but the line is not sharp and both the Heath and Moorland articles describe each as closely related to the other with no agreed boundary.
What would resolve this A published vegetation-classification standard drawing an explicit, measurable line between heath and moorland (by elevation, rainfall, peat depth or floristic composition) accepted across the ecological literature, rather than the regional and traditional usage the sources currently describe.
