 ====Understorey Max Diameter====
 :Upper diameter limit for understorey trees in thinnings (cm). Trees with dbh lesser than this value will be considered understorey trees (in mature stands, not in plantations). Note: Setting this to 0 means that no trees will be considered understorey trees.
 ====Understorey Cleaning Stems Threshold====
 :Minimum understorey stem density required for understory cleaning to be performed (stems/ha). If the number of understorey stems is less than this parameter, no understorey cleaning will be performed, but the harvester cost may increase due to the hindrance of understorey. For example, with 4000 undestorey trees, the harvester productivity will decrease with 3 percent.

 ====Max Relative Age====
 :Time for last thinning in terms of maximum relative age. If relative age is larger, then no more thinning will be simulated. Relative age is an approximation for how close a stand is to culmination of mean annual growth (MAI).
