Plot ordinations vs. species ordinations<br />

• In plot ordinations, each point represents a plot (relevé) and the greater the distance<br />

between any two points, the greater the difference in floristic composition of the plots.<br />

• In species ordinations, each point corresponds to a species point of central tendency.<br />

Distances between species are an approximation of their degree of similarity in terms<br />

of their distribution within plots.
