Sentence examples for mean tree heights from inspiring English sources
For Pinus contorta, mean tree heights at the time of treatment ranged from 4.4 – 7.7 m (Table 2).
Although MCH may underestimate the canopy heights in complex terrain under the circumstance of reduced data density [27], it has excellent agreements with field-measured maximum and mean tree heights at least in low-slope environments [28] as well as the field-measured basal area [29].
Mean tree heights at the time of treatment ranged from 1.5 – 12.0 m (Table 2).
While mean tree heights for 'Tangoio' wands and stakes were less than this (4.82 and 3.92 m, respectively), the range among replicates for this clone suggests that growth performance was similar (wands 4.37 5.35 m, stakes 2.95 4.50 m).
adiameter at breast height, broot collar diameter, ctotal above-ground biomass, dtotal below-ground biomass including stump/root bole, etotal root mass excluding the stump/root bole Fig. 4 Mean tree heights for nine trial species 0 3 years after planting.
During this time the mean tree heights were between 2.5 to 24.4 m and the stand L increased to its peak at about age 3 years before stabilizing and finally declining towards the end of the rotation (le Maire et al. [2013]).
Tree form and mean tree height in eroded and non-eroded plots were not significantly different.
We conclude that where horizontal structure is not limiting, forest stands regenerated by clearcutting may provide suitable habitat for resident, nonjuvenile marten when the following thresholds are reached: live-tree basal area ≥18 meana, mean tree height ≥9 m for trees with dbh ≥7.6 cm, and snag volume ≥10 m3/ha.
Correlation analysis that included data from all 15 plots (and therefore data from both beech and birch forest and both mountains) suggested that the aboveground vegetation properties, such as aboveground biomass, mean tree height, and stand density, were strongly correlated with the SOC stock.
Within each sub-plot different structural tree parameters (e.g., diameter at breast height, mean tree height etc).
Although changes to these latter features do not significantly affect the precision of regression equations for common stand dimensions (basal area, volume or mean tree height) coefficients in the regression equations are likely to change between acquisitions at different altitudes (Næsset [2004a], [2009]).
