Population is a term that refers to a group of individuals from the same species that live in the same place at the same time. Plant population is the number of plants per unit area.
Species is a collection of closely related organisms that are genetically similar. The individuals of species can generally interbreed and produce fertile offspring.

Population density is the number of individuals living in a particular region. To calculate the population density, we consider the number of people living in the selected area and divide the number by the size of the area.

The Quadrat method is used to calculate the plant population density. Quadrat is a square of a specific size, usually of 1-meter square. These squares are chosen randomly and generally marked with wire outlines.

Typically, a succession of quadrats is sampled to allow comparisons between phenomena, such as the distribution of a specific plant in two distinct places.

The plant population density by quadrat method is calculated as:
Density = Total number of individuals of the species in all the sampling units (S) / Total number of sampling units studies (Q)
