Some grammar changes. I think it still needs to be rephrased, but it is at least better than it was. |

Line 5:
'''Tree allometry''' establishes quantitative relations between some key characteristic dimensions of [[tree]]s ([[Forest inventory|usually fairly easy to measure]]) and other properties (often more difficult to assess). To the extent these statistical relations, established on the basis of detailed measurements on a small sample of typical trees, hold for other individuals, they permit extrapolations and estimations of a host of [[dendrometry|dendrometric]] quantities on the basis of a single (or at most a few) measurements.
The study of [[allometry]] is extremely important in dealing with measurements and data analysis in the practice of [[forestry]]. Allometry studies the relative size of organs or parts of organisms. Tree allometry narrows the definition to applications involving measurements of the growth or size of trees. Allometric relationships often are
The use of [[allometry]] is widespread in [[forestry]] and [[forest ecology]]. In order to develop an allometric relationship there must be a strong relationship and an ability to quantify this relationship between the parts of the subject measured and the other quantities of interest.<ref>Smith, W.B., and G.J.
