Height trajectory for Beech in Sweden from FAKTA SKOG nr. 14 2013

Description

"Beech and Oak: The curves are based on permanent experimental plots in beech and Oak stands, which are followed with repeat measurements. The same plots were used in the 1970's for develop height development curves and production models for beech and oak stands, but longer time series have been available this time."

Usage

Johansson_2013_height_trajectory_Sweden_Beech(
  dominant_height,
  age,
  age2,
  output = "Height"
)

Arguments

dominant_height

Dominant height of stand, m.

age

Total age.

age2

Total age at output age.

output

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

Details

29 plots. 40 observations.

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 named list with 2 elements: I) "Equation": text response with the equation for that height curve.
