Q

If a piece is cut at the top and broken at the butt it is classified as….

A

Trick question

  • If it is in an accumulated sub pop. it is recorded as bucking waste
  • If dispersed it is normal (unavoidable) breakage and not recorded.

Q

List the progression of more recent history on utilization.

A
Sympathetic admin (1980's) higher benchmarks due to recession
Zero tolerance 85-98 (all logs must go except for Y, otherwise full stumpage)
Take or Pay (current, must pay if your waste exceeds benchmarks)

Q

Minimum plots per stratum?

A

2

17
Q

Why do we stratify?

A

Increases sampling precision, allowing for less necessary plots.

18
Q

If there is evidence of excessive breakage, how would you grade breakage?

A

as a 5m log

19
Q

How are stumps graded typically?

A

J if 13R or greater

U if 12R or less

20
Q

Logs less than 5 meters and bucked on the butt will be grades as if…

A

they were 5 m long

21
Q

How to grade bucking waste?

A

greater than 8 rad top: J

Less than 8 rad top: U

22
Q

Define Population, Sub population, stratification as they relate to R and W.

A

Population: Volume of waste left behind
Subpop: Accumulated (roadside/spot), dispersed and standing groups
Stratification: population is split into groups to increase sampling precision
