Additional Spatial Aggregation & Resolution Information: Results are given at an annual resolution and represent average forest structure across of the entire forest (i.e. all simulation patches).
Temporal Resolution Of Input Data: Climate Variables: monthly
Temporal Resolution Of Input Data: Soil: constant
Key model processes
dynamic vegetation: Yes, forest dynamics emerge from interactions between individual tree cohorts. Establishment, growth and mortality are simulated explicitly and are influenced by environmental conditions (availability of light, water, nutrients).
nitrogen limitation: Yes, nitrogen limitation is considered via a growth-reduction factor (i.e. nitrogen limitation decreases tree growth, depending on species-specific nitrogen demand).
CO2 effects: No
light interception: Yes, light interception through the canopy is simulated via the Beer-Lambert law.
light utilization: No, photosynthesis is not simulated explicitly
water stress: Yes, water stress is represented via a drought-index (depending on site-specific soil water holding capacity, precipitation and topography).
heat stress: No
Evapo-transpiration approach: Thornthwaite and Mather (1957)
Differences in rooting depth: No
Carbon allocation: Tree growth is simulated for each cohort using the carbon budget model by Moore (1989) modified according to the constraints by soil moisture, degree-day sum, nitrogen availability, light availability, and crown length
Regeneration/planting: Yes, both natural regeneration and planting can be represented
Soil water balance: Yes, a site-specific water balance is calculated (see Bugmann and Cramer, 1998, Forest Ecology and Management 103)
Causes of mortality in vegetation models
Age/Senescence: Age- and growth-related mortality are considered. Growth-related mortality is climate dependent.
Drought: A drought-index is calculated (depending on site-specific soil water holding capacity, precipitation and topography).
Harvest: The model allows to simulate a wide range of planting, cutting and thinning techniques (see Rasche et al., 2011, Journal of Applied Ecology, 48).
