Sentence examples for mean tree volume from inspiring English sources

The analysis variables are: volume per hectare (m3 ha−1), stocking (trees ha−1), and mean tree volume (m3).

As with volume and stocking, mean tree volume varied considerably when 10-m-long cells were used (Figs. 3 and 4).

When the known positions of trees are relatively inaccurate, using mean tree volume and stocking rate per cell might be a method for mapping productivity from harvester data.

However, this study has shown that even if the position of trees is not accurate, using mean tree volume and stocking rate per cell can be a method for mapping productivity from harvester data.

A significant decrease in the mean tree volume produced when slash was removed was observed across all sites in both the first trial series (F1R and F2R) and second trial series (S2R and S3R).

A suitable spatial resolution for studying variations in stand productivity, mean tree volume, and stocking rate across stands were established that enabled useful forest-yield maps from harvester data to be developed.

Field inventories showed that the mean living tree volumes were relatively similar in the studied sites, but the volumes of dead wood differed greatly.

Also working in the area that is currently part of the Kalevala National park, Lampainen et al. (2004) examined a 350-ha pine dominated forest 31 years after fire, where mean standing kelo tree volume was 25.6 m3∙ha−1.

Cutting productivity was 3 11oven-dry tons (ODt) per effective hour (E0-h), and was highly dependent on stand characteristics (e.g. mean whole-tree volume).

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]).

Compared to the mean tree (tree with the mean stem volume) in the stand, growth reduction of dominant spruces was about 8 17 percentage points stronger.
