Linear growthThis behavior does either diameter or height growth as a linear function of GLI. Parameters for this behavior| Parameter name | Description |
|---|
| Simple Linear - Diam Intercept in mm/yr (a) | Intercept of the linear growth function, or growth at no light, in mm/yr, for diameter growth. | | Simple Linear - Diam Slope (b) | Slope of the linear growth function, for diameter growth. | | Simple Linear - Height Intercept in cm/yr (a) | Intercept of the linear growth function, or growth at no light, in cm/yr, for height growth. | | Simple Linear - Height Slope (b) | Slope of the linear growth function, for height growth. |
How it worksThis behavior calculates an amount of diameter or height growth as: Y = (a + (b * GLI)) * Twhere - Y = amount of radial increase, in mm, or amount of height increase, in cm
- a = Simple Linear - Diam Radial Intercept in mm/yr (a) parameter (for diameter growth) or the Simple Linear - Height Intercept in cm/yr (a) parameter (for height growth)
- b = Simple Linear - Diam Radial Slope (b) parameter (for diam growth) or the Simple Linear - Height Slope (b) parameter (for height growth)
- GLI = global light index, as a percentage between 0 and 100, calculated by a light behavior
- T = number of years per timestep
How to apply itThis behavior can be applied to seedlings, saplings, and adults of any species. Any tree species/type combination to which it is applied must also have a light behavior applied. You can choose either a diam with auto height, diam only, or height only version. |
