# Radiata pine total AGB, weighted arithmetic model Eq. 14

Aboveground biomass equation for Pinus radiata, New Zealand, from Moore 2010. 637 trees, DBH 0.7–80.6 cm. Listed on Tree Allometrics, a free library of tree allometric equations, each quoted from the source that published it.

## Equation

As printed in Moore 2010 (Section 2.2, Eq. 14):

> AGB = β0 (D2H)β1 (14)

Cite: https://treeallometry.org/equations/moore-2010-eq14/#equation

In this library's units, ready to compute (aboveground biomass in kg):

```
Aboveground biomass = 0.1039 * (D^2 * H)^0.8229
```

Inputs: D = Diameter at breast height (1.3 m) (cm); H = Total tree height (m).
The source's own form: 0.1039 * (D^2 * H)^0.8229, with D in cm, H in m; output in kg.

A missing fit statistic is one the source doesn't state, or that we haven't recorded; it is never estimated. Outside the stated DBH range or region, the equation is an extrapolation.

## The facts, in the source's words

**Equation** (Section 2.2, Eq. 14):

> AGB = β0 (D2H)β1 (14)

Cite: https://treeallometry.org/equations/moore-2010-eq14/#equation

**Equation** (Table II, row Eq. 14 (parameter estimates)):

> 0.1039 | 0.8229

Cite: https://treeallometry.org/equations/moore-2010-eq14/#quote-expression

**Trees measured** (Section 2.1):

> biomass measurements for 637 individual radiata pine trees from 13 different studies

Cite: https://treeallometry.org/equations/moore-2010-eq14/#quote-fit-n-trees

**R²** (Table II, R2 column, Eq. 14):

> 0.94

Cite: https://treeallometry.org/equations/moore-2010-eq14/#quote-fit-r2

**Our note:** D in cm, H in m, AGB in kg. Fitted directly on the arithmetic scale, so no correction factor. Fit ranges are the pooled data (Table I overall). Eq. 18 under-predicts large trees according to the paper (Section 3.2).

## Checks this equation passes

On every build, the library's form and the source's own form (in its units) must both give these values within 1%.
