2.5.2. EM38 measurements
Measurements of ECa (EM38H and EM38V) were made on a systematic
grid within each tree measurement plot. Measurements
were taken in the interbed area between each set of 4 trees (2
rows × 2 trees). A total of 36 measurements of ECa were made in
each plot at a nominal grid spacing of 4 m and 2.5 m. Values of ECa
were converted to ECe, and were averaged to obtain a single value
of ECe for each plot.
For a subset of trees in plots of E. camaldulensis and E. globulus,
additional EM38H and EM38V measurements were made at
two positions approximately 0.5 m adjacent to the base of each
tree, and the two EM38 measurements were averaged to provide a
representative value of EM38H and EM38V at each tree location.
