What Is Vegetation Density

Density in vegetation measurement refers to the number of individuals per unit area (for example plants/m2). The term consequently refers to the closeness of individual plants to one another. The measure of density is often applied when we want to monitor changes in a given vegetation species over long periods.

How do you find the density of a forest?

To calculate the QSD, first divide the basal area of the diameter class by the number of trees in the class to find the basal area of the average tree. Then the dbh = 2 x {square root (basal area/3.142)}. For example, the dbh of a tree of basal area of 707 cm2 = 2 x {square root (707/3.142)} = 30 cm.

How do you calculate density?

The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.
