| I used relative basal area as a measure of importance, because that value is less influenced by differences in sampling procedure than is relative density. |
| Peak and relative density counts were combined to arrive at density estimates for each species in each year at each blind. |
| For ground, sub-canopy and shrub vegetation, importance values were calculated using relative cover, relative frequency and relative density. |
| The average importance value for each tree species in each plot was calculated as the mean of the relative basal area and the relative density. |
| The critical relative density is determinated for the failure models under aerodynamic pressure load. |
| However, the relative density of this species was negatively correlated with tree age in the sapling layers of abandoned agriculture plots. |
