Golden Plover do like heathery areas - particularly with peat 'Hags' and patches of bog - for feeding, but for breeding they like flattened hillock tops with short grass for unobstructed views of the approaching Hen Harriers...... Sadly, any views of Hen Harriers are no longer such an issue in England
The problem is that although the current environment is not the original one, it is still important as it is now - the Blanket Bogs and Semi-improved grasslands of upand Snowdonia / Lakes are very important habitats in their own right and reforestation could lead to local / national extinction of many threatened species.
I spent several days this summer out surveying the Migneint for Golden Plover. Sadly I didn't find any, and part of the reason is that a lot of Plover habitat has been lost through UNDER grazing of the area - what were once close cropped grassy hillocks are now covered with rough heather scrub and the Plovers need to have the open summits for nesting on in order to keep watch for predators.
I agree totally with Shewie - lightweight trail shoes (or even sandals if you can find ones without a slippery footbed) let your feet breathe so you no longer worry about wading through rivers or bogs because your feet get used to the moisture and dry very quickly.
The "ankle support" thing is really an old myth - I've only sprained an ankle when I've been wearing boots, and the time when my feet / ankles feel by far the best is when I walk barefoot (even with a heavy pack) !
I too only wear boots when I might need crampons in winter.
"in the mountains I do what I'd do with my own, dig a hole and bury."
Actually, although it's cosmetically more acceptable to bury in a hole, from both a biodegradability point of view and a disease control perspective it's far better to leave the faeces (yours or dogs) exposed to wind, rain, sunlight ahd beetles rather than hiding it away.
The Woodland Trusts (and Forestry Commissions) approach of 'stick and flick' has been developed with both this and the 'Xmas tree bags' issues in mind.
