Silvicultural Implications in Timber Harvest Residues

When trees are harvested for sawtimber or pulpwood, the stems are either cut to length in the forest before being mechanically forwarded to the roadside or landing, or they are extracted as whole stems …

Five major classes of residue biomass harvesting can adopted, each with its own silvicultural implications.

1. Harvesting residues can occur either simultaneous to a roundwood harvest (one-pass method) or following logging operations (two-pass method) (Richardson et al., 2002). This type of

Damage to residual stems during thinning operations typically occurs during felling and skidding activities and can be minimized by:

• Selecting an operator who has experience performing thinning treatments.
• Conducting an on-site preharvest meeting with the buyer and operator.
• Carefully planning

Silvicultural Implications in Shrub Biomass Utilization

In many regions of the United States, forest stands contain high levels of competing native and non-native shrubs that pose a significant challenge to regeneration efforts (Royo and Carson, 2005). Typically, site preparation techniques …

Silvicultural Implications in Low-Value Species and Below-Grade Utilization

Many forest stands have a legacy of exploitation, leaving the forest depleted and high-graded. In particular, a large proportion of hardwood forests fall into this category (Koch, 1985; Hicks et al., 2004). …

Silvicultural Implications in Small-Diameter Woody Biomass Utilization

Small-diameter trees have historically been utilized for the manufacture of paper, particleboard, fiberboard, and other reconstituted products. However, because of the shutdown of many paper mills, the demand for these trees has been …

The emergence of new markets for hardwoods as raw material for biofuels is likely to exacerbate limitations on hardwood availability. Eucalyptus may offer new …
