1Appraisals
(pre-harvest cruising)
Determine value ($) of standing timber.
Systematic grid with random start.
Variable radius plot or 100% tally of designated cut trees
+/-10% (67% Confidence level) for volume estimation and within specified tolerance levels.
2 CFI
Determine timber volume, assess current and potential forest growth and yield, and measure the forest trend toward desired objectives.
40 x 40 chain Reservation wide grid (80 acres per plot)
1/5 acre fixed plot with four 1/250th subplots.
Measurements must be within specified tolerance levels.
3 Stand Exams
Determine timber volume, assess current stand conditions for silvicultural planning purposes.
Systematic grid with random start
Variable radius plot with 1/100th acre fixed area subplot.
+/-20% (67% Confidence level) and within specified tolerance levels.
