one of the typical life zones on mountains is the montane forest: at moderate elevations, the rainfall and temperate climate encourages dense forests to grow. holdridge defines the climate of montane forest as having a biotemperature of between , where biotemperature is the mean temperature considering temperatures below to be . above the elevation of the montane forest, the trees thin out in the subalpine zone, become twisted krummholz, and eventually fail to grow. therefore, montane forests often contain trees with twisted trunks. this phenomenon is observed due to the increase in the wind strength with the elevation. the elevation where trees fail to grow is called the tree line. the biotemperature of the subalpine zone is between .

savernake is a coppice-with-standards forest and an ancient woodland. a coppice is a wood where broad-leaved trees, typically hazel, grow out of the stumps or "stools" left from previous cuttings. standards are trees allowed to grow to maturity. if these trees are allowed to grow in close proximity they grow straight and tall. if they have more room to grow then side branches become substantial.in the past standardisation was not at all essential. craft work and early mechanical industry, such as shipbuilding, wagon making, and furniture making all required "bends" and "knees," as well as other eccentrically shaped pieces which the side branches would provide. trees such as beech and oak can be pollarded, a process whereby a standard is cut two-thirds up its trunk. multiple boughs grow from the cut point and the life of the tree is extended and curved pieces of bough or trunk are often produced. such trees become magnificent specimens and they live through generations of forest workers. their base trunk attains great girth. often the side boughs become too heavy and are broken in stormy weather. in other cases the bough weight (an outward force) begins to tear the lower trunk apart creating a cavity which can over decades become cavernous in size. the oldest of these pollarded trees is the "big belly oak" beside the a346 road. big belly is one of fifty great british trees named and honoured as part of the queen's golden jubilee celebrations. it has a girth of and is 1000–1100 years old. in 2001 it was in danger of splitting in two, a fate that had already overtaken the similarly aged duke's vaunt. to prevent this, the tree was fitted with a metal corset. the 2011 radiohead album "the king of limbs" is named after the ancient king of limbs tree in the forest near tottenham house, where the band recorded part of their previous album, "in rainbows".
