Fodder pollards produced "pollard hay" for livestock feed; they were pruned at intervals of two to six years so their leafy material would be most abundant. Wood pollards were pruned at longer intervals of eight to fifteen years, a pruning cycle tending to produce upright poles favored for fencing and boat construction. Supple young willow or hazel branches may be harvested as material for weaving baskets, fences, and garden constructions such as 1841: 1819: 455: 1777: 1735: 1805: 375:

growth may be pollarded. In these species (which include many broadleaved trees but few conifers), removal of the main apical stems releases the growth of many dormant buds under the bark on the lower part of the tree. Trees without this growth will die without their leaves and branches. Some smaller

An incidental effect of pollarding in woodland is the encouragement of underbrush growth due to increased light reaching the woodland floor. This can increase species diversity. However, in woodland where pollarding was once common but has now ceased, the opposite effect occurs, as the side and top

Pollards cut at about a metre above the ground are called stubs (or stubbs). These were often used as markers in coppice or other woodland. Stubs cannot be used where the trees are browsed by animals, as the regrowing shoots are below the browse line.

tree species do not readily form pollards, because cutting the main stem stimulates growth from the base, effectively forming a coppice stool instead. Examples of trees that do well as pollards include broadleaves such as

of the top part of the tree. Older pollards often become hollow, so it can be difficult to determine age accurately. Pollards tend to grow slowly, with denser growth-rings in the years immediately after cutting.
175:. In some areas, dried leafy branches are stored as winter fodder for stock. Depending on the use of the cut material, the length of time between cutting will vary from one year for tree hay or 443:"pollard" came to be used as a verb: "pollarding". Pollarding has now largely replaced polling as the verb in the forestry sense. Pollard can also be used as an adjective: "pollard tree". 241:, the majority of which was pollarded until the late 19th century. Here, the light that reaches the woodland floor is limited owing to the thick growth of the pollarded trees. 1378: 385:
Oaks, when very old, can form new trunks from the growth of pollard branches; that is, surviving branches which have split away from the main branch naturally.

Pollarding was preferred over coppicing in wood-pastures and other grazed areas, because animals would browse the regrowth from coppice stools. Historically in
