Population size, more technically called population density (designated as $N$) need not necessarily be measured in numbers only. Although the total number is the most appropriate measure of population density. But in some cases in is different to determine

For example

In a forest area suppose there are $200$ Parthenium plants but only a single banyan tree will huge canopy

The following inference could be made

$(i)$ Population density of banyan is low

$(ii)$ Population cover area of banyan to high

In this example percentage of cover of biomass is more meaningful than population size
