In several
countries, there are systems to prevent forest soil from destruction by forest
operations. One example is the Saxonian technological map where the soil
conditions are divided into 5 trafficability classes.
In Technodiversity,
the technogram of a stand as well as the ecogram of harvesting methods
have as their x-axis the T-classes. They are seen as crucial criterion how much
the soil will react to any technical impact. This is the scientific context of
traffic on bare grounds.
As the guiding
criterion we take the soil moisture and divide it into 5 trafficability-classes. Dry (T1), fresh (T2), moist (T3),
wet (T4) and very wet (T5). These classes correspond with the assessments of
soil sciences.
