To pollard a tree is to cut off its top — and often the big upper branches — so a thick head of new shoots grows out lower down. Town trees, willows, and old street trees are often treated this way, so they stay a useful size and do not smash windows or wires.

The word is built from an old poll, 'head,' plus -ard, the same kind of ending as in drunkard and coward; the picture is a tree given a cut 'head.' Farmers used related talk for animals whose horns were taken off at the head — headed, not horned — and that 'cut head' idea moved onto trees.
