Sentence examples for basal area at the from inspiring English sources
Results showed that thinning resulted in significant reductions in tree density at both sites, as well as reductions in tree basal area at the Goose Pond site.
These findings demonstrate the utility of ANNs for integrating satellite data from the Landsat ETM+ spectral bands 3, 4, 5 and 7 with limited field survey data to assess patterns in basal area at the landscape scale.
Fig. 5 Mean tree diameter and stand basal area at the moment of fertilization in the optimized management schedules.
Forest structure was represented by stand basal area at the time of first measurement as delivered by the different NFIs, and the variable F-rDiffDq, a proxy for the social position of each tree within the stand defined as: mathrm{F}-mathrm{rDiffDq}= DBH/ DBHmathrm{q}hbox 1 (1).
For the stand values we compared observed and predicted height:diameter ratios of dominant trees (100 largest trees per hectare), and of the mean stem size (quadratic mean diameter and Loreýs mean height weighted by basal area) at the end of the simulation period.
The results showed that the allometric method is applicable to isolated trees with regular shapes; however, because the LAI of P. euphratica was calculated from an allometric equation based on the basal area (at 1.3 m), the allometric equation is prone to failure if the basal area is beyond a specific range.
Table 2 shows that the stand basal area at cutting is larger for the young initial stands but the mean tree diameter is smaller, suggesting that high stand densities call for earlier cuttings, which is a logical result.
Using linear mixed models, we evaluated the effects of current and historic fragment size, landscape forest cover and land use changes on the density and basal area at stand level, and considering the two different strata (upper and middle).
Table 2 shows the distribution of vegetation used for the experimental stimuli, based on the basal area at breast height in May (in October).
Periodic annual increment for basal area and volume varied significantly by periods for all sites except the basal area at one site.
In addition, some residual 2,4-dihydroxy-7-methoxy- 2H -1,4-benzoxazin-3- 4H -one (DIMBOA), a natural antibiotic compound, was detected in the basal area at 30 days after silking.
