Carbonnier 1975 Height growth of Oak plantations in Sweden.

Description

Largely based on the Fortran IV script appended to the original source. Checked against table VI.1 (ibid), p. 66.

This function was written by Björn Hägglund following the same method as outlined in Hägglund 1972.

Usage

Carbonnier_1975_Sweden_height_trajectories_Oak(
  total_age,
  top_height_m,
  age_2,
  output = "SIH100"
)

Arguments

total_age

total age of stand or tree.

top_height_m

Top height of tree or stand in m.

age_2

Necessary if output is "Height". The age for which height along the same curve is to be computed.

output

One of "SIH100", "Height", or "Equation".

Details

multiple correlation coefficient: 0.995

100*spread around the function/spread around the mean: 10.1

spread around the mean of ln(height): 0.30096

Value

If output is "SIH100", the numeric value for the height (m) a stand will reach at age 100.

If output is "Height", the numeric value for the height (m) a stand will reach at age_2.

If output is "Equation", a text response with the equation for that height curve.
