The actual height growth of sprouted cohorts ($i_H$ in Eq 4 here) is multiplied by the species parameter (“sapSproutGrowth”). Actually, the relative height growth (i.e., environment response * light response, a value between 0 and 1) is modified (see also sapling growth and competition). This has the consequence that sprouts are less prone to stress (and thus mortality), as the (increased) relative height is compared against the species-specific threshold to determine the stress status of a sapling. Furthermore, the height growth of a sapling can exceed the height growth potential given for the species. Whenever a cohort reaches the height of 4m, individual trees are created, which behave exactly like non-sprouted trees (e.g., there is no effect on e.g., root biomass). The effect of increased height growth of sprouts can be best tracked/ tested using the “Sapling growth” debug output (Debug output). Note, that the output contains average values per resource unit and species (and not data for individual cohorts). However, the effect should be visible when looking at the average height growth, and the duration between establishment (cohorts appearing under “Added”) and recruitment (“Recruited”-column).
