Type of Survey Purpose Design Plot Layout Accuracy Standards

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.

4 FireMonDetermine fuel loadings before and after fuel reduction treatments

Several random plots within treatment area
