For ground, sub-canopy and shrub vegetation, importance values were calculated using relative cover, relative frequency and relative density. |
Peak and relative density counts were combined to arrive at density estimates for each species in each year at each blind. |
The layers would reflect the relative density of the crystals and the order of crystallization. |
No natural reactors exist today, as the relative density of fissile uranium has now decayed below that needed for a sustainable reaction. |
However, the relative density of this species was negatively correlated with tree age in the sapling layers of abandoned agriculture plots. |
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. |
