I had to Google 'pollard' as I don't think I've ever seen it used as a word, I thought it was a surnameI maintain a previously neglected 5 acre wood behind my house. Lots of mature trees and saplings. Lots of stuff falls over or off. I clear up, cut down, thin, pollard, cut and lay hedges. Split and stack homegrown firewood, and inevitably have regular large bonfires throughout the year to get rid of the small branches, sweepings, brambles, and the rotten wood that is no good for burning indoors. Basically stuff that will not go on the compost heap. I view this as part of a sustainable ecosystem in equilibrium ( in fact more productive under active management) and one that has a useful output, as well as being amazingly therapeutic.
