Species/DBH/Percent Cover Table
Starting with the uppermost stratum, list all the species present and cover class (using the scale provided
below) and percent cover of each species in that particular stratum. Indicate strata in the left-hand
columns. If in the tree layer (single-stemmed woody plants, generally 5 m in height or greater at
maturity), note in the “T” column if T1 (emergent tree), T2 (tree canopy), or T3 (tree sub-canopy). If in
the shrub layer, note in the “S” column if S1 (tall shrub) or S2 (short shrub). If in the ground layer, note in
the “G” column if H (herbaceous), N (nonvascular), V (vine/liana), or E (epiphyte).
For plots with trees, list the DBH (in cm) of all trees above 10 cm diameter. Separate the measurements
with a comma. For plots with very high tree density DBH measurements will be done in a subplot. If the
number of trees with a DBH greater than 10 cm is more than about 25, divide the plot into quarters and
measure the DBH of trees in the southeast quadrant, or the quadrant nearest southeast. CLEARLY NOTE
on the form that this is what you’ve done.
