Tree Measurements
 Species (commercial and non-commercial)
 DBH (for plot trees)
– >4.0 cm at 1.3 meters (Up hill side)
 Classification
– Tree Class (pathological indicators)
» 1, 2, 3, 4, 5 or 6
– Crown class (position in the crown relative to other trees)
» 1, 2, 3, 4, 5 and ( 6 )
– Live crown length (contiguous live crown)
» 10% to 100% (in 10% increments)
 Sectors (tagging and site)
 Stumps ‘O’ or ‘N’
 Damage Agents and Severity (tree and sample)
 Suitable for height?
17
Sample Setup
 Centre stake flagged and cairn of rocks for
protection
 Triangulate (bearing and horizontal
distance from plot centre) centre stake to
three tagged healthy plot reference trees
near plot centre
 Confirm slope corrected plot perimeter
 String perimeter and sectors
 Ensure nails on plaques and tree tags will
allow for growth
 Record plot attributes (crown closure,
slope, aspect, elevation, slope position,
damage to reflect tree damage)
18
What is a Dead Tree?
Alive?
 Any tree with one or
more green needles
 Bark may or may
not appear to be
alive
Note: Use tree
comments for
questionable trees!
19
Dead Trees
 Standing trees >10.0 cm dbh and >1.3m in height
– Tag, measure DBH and classify dead tree attributes
Dead Tree Attributes
 Tree number and tree number certainty
 Species & species certainty
 Vertical position (standing or down)
 If standing: broken top and height to break
 If down: supported or on the ground
 Wildlife tree appearance (1 - 7) Appendix 22

The Sub-Plot
 Target is 20 commercial trees
– 0.3 m in height to 3.9 cm in DBH
 For trees 2.0 cm to 3.9 cm in DBH
– Tag and classify as in plot
– Insert near tree number as out of sequence
 For trees under 2.0 cm in DBH
– Do a dot count by species and “class”
0.3 to 1.3 m in height
0.1 to 1.9 cm in DBH
- [D Class = 0]
- [D Class = 1]
25
Height Sample Trees
For first two majors
– Top height tree (software selected in centre
sector “C”)
– Site trees (software selected in site sectors)
» 4 - 10 (proportionate to plot size / 0.01 ha)
» Must be “suitable”
» no substitution!
– Fifteen others (down to 2.0cm dbh)
Other majors, minor and scattered
– Up to fifteen if suitable and available
Mark direction for height with painted dot
26
Top Height Tree
 Largest dbh tree in a 0.01ha plot (Centre sector
“C”)
Measurement specific
 Suitability
– Crown class 1 or 2 (not suppressed or residual)
– No major defects (healthy)
– Within 5% of original height (no major top damage)
 No substitution!
27
Site Trees
 Largest dbh tree per 0.01ha plot
(software will select from site sectors)
– Collect for the first two leading major species
Measurement specific

Suitability
– Crown class 1 or 2 (not suppressed or residual)
– No major defects (healthy)
– Within 5% of original height (no major top damage)

Confirm veteran age
Save cores in labelled straw (sample + tree number)
Want 2 cores per species to have pith
Measure 5, 10, 20 radial increment
Assess for suppression
Estimate age for rotten cores
