Description Usage Arguments Value Note Author(s) See Also Examples

Mean tree dbh is estimated as the the dbh of the mean basal area tree: \bar{d} = 2 \cdot √{\frac{G}{N * π}} at forest level or \bar{d} = 2 \cdot √{\frac{g}{n * π}} at plot level

1	ttMeanDbh(basalArea, treeDensity)

`basalArea`	basal area at plot level or forest level
`treeDensity`	count of trees at plot level or forest level

a single numeric value (estimate of mean tree dbh), not rounded, in the same unit of measure as basal area

The unit of measure of the result if the same as the basal area
