Analysis of Linear Hybrid Systems in CLP,eration process. Using these indices as model inputs, clearcuts and burns can be classified; within each stratum the natural forest regeneration process is similar. Analysing these strata, one can select a regime of forest treatment that is appropriate for a given stratum and, consequently, for the clearcuts (or burns) it includes.

To reduce soil disturbance and tree damage, smaller machines or machines with less ground pressure must be considered. Today the traffic may cover 10–30% of the site area. This is mainly due to skidding during clear-felling and t
