Tree taper is the degree to which a tree's stem or bole decreases in diameter as a function of height above ground. Within Forestry and for the purposes of timber production, trees with a high degree of taper are said to have poor form, while those with low taper have good form. The opposite is the case for open-grown amenity trees.
Site index – a species specific measure of site productivity and management options, reported as the height of dominant and co-dominant trees in a stand at a base age such as 25, 50 and 100 years; Tree taper – the degree to which a tree's stem or bole decreases in diameter as a function of height above ground. So it can be sharp or gradual.

Tree taper – the degree to which a tree's stem or bole decreases in diameter as a function of height above ground; Girard form class – an expression of tree taper calculated as the ratio of diameter inside the bark at 16 feet above ground to that outside the bark at DBH, primary expression of tree form used in the United States
Girard form class is a form quotient calculated as the ratio of diameter inside bark at the top of the first 16 foot log to the diameter outside bark at breast height ().Its purpose is to estimate board-foot volume of whole trees from measurement of DBH, estimation of the number of logs, and estimation of the taper of the first log, based on the general relationships identified between the ...

Knees with very little taper A bald cypress exhibiting tapered knees. A cypress knee is a distinctive structure forming above the roots of a cypress tree of any of various species of the subfamily Taxodioideae, such as the bald cypress.

Although "tree" is a common word, there is no universally recognised precise definition of what a tree is, either botanically or in common language. [ 1 ] [ 2 ] In its broadest sense, a tree is any plant with the general form of an elongated stem, or trunk, which supports the photosynthetic leaves or branches at some distance above the ground ...
