Wisconsin's Forestland Woody Biomass Harvesting Guidelines

Figure 2-6. Tops and limbs are being redistributed onto this site by a grapple skidder
is occurring, then the tops and limbs of one out every 10
trees needs to be hauled back into the general harvest
area and evenly scattered over the site (Figure 2-6).
The ultimate goal is to have 5 or more oven dry
tons per acre of FWD on site following the harvest.
Following these guidelines should achieve that standard
on most average sites. If a site lacks woody debris,
consider retaining more FWD and/or CWD than is
recommended by Guidelines 1.A and 2.A (Figure 2-7).
Figure 2-7. Consider retaining additional woody debris when harvesting in forests that
have little dead wood on the forest fl oor.
