The species are ranked by pH preference, from most acidophile down to most basiphile (based on ECOFACT Ellenberg Factors).

This table shows the striking contrast between the varied and basiphile associates in sites such as Widdybank Pasture or Glen Fender Meadows, and the acidophile associates at e.g. Butterburn Flow.

Very remarkably, the Hybrid Deergrass and Cross-leaved Heath (the latter in only one list) are the
only associates in common between the list for Widdybank/Glen Fender (pH around 3–9 – Ellenberg) and Butterburn Flow (pH around 1–2)!

One wonders if there are two ecotypes involved here.

It is planned in future seasons to survey the water regimes of a selection of these sites for parameters such as pH, solutes concentration, and dissolved oxygen.
