The term 'slash' in forest management refers to:
Answer: Logging debris such as limbs, tops, and other woody material left after harvest
Slash is the residual woody debris — branches, tops, bark, and small-diameter material — remaining on the ground after timber harvesting.
A 'timber cruise' is conducted to:
Answer: Estimate the volume and value of timber in a stand before harvest
A timber cruise uses systematic sampling to estimate the total volume, species composition, and value of merchantable timber in a stand prior to sale.
What is the primary purpose of a buffer strip along streams during logging operations?
Answer: Filter sediment and protect stream bank stability and aquatic habitat
Streamside buffer strips (riparian management zones) are left unlogged to stabilize banks, filter runoff, maintain shade, and protect aquatic and riparian habitat.
In timber harvesting, 'bucking' refers to:
Answer: Cutting felled trees into log lengths
Bucking is the process of cross-cutting a felled tree stem into individual log lengths for transport and processing at a mill.
Which of the following is a key advantage of reduced-impact logging (RIL) techniques?
Answer: Reduces damage to residual stand and soil compared to conventional logging
Reduced-impact logging uses pre-harvest planning, directional felling, and controlled skid trail placement to significantly reduce damage to remaining trees and soils.
What does 'chain of custody' certification mean in the context of timber harvesting?
Answer: A system tracking certified wood from forest to final product
Chain of custody certification verifies that wood products can be traced from a certified, sustainably managed forest through each stage of processing and sale.
