Can a species of plant have a high relative density but a lower relative frequency?

Yes, a species of plant can have a high relative density but a lower relative frequency. Relative density measures the number of individuals of a species in a given area compared to the total number of individuals of all species, while relative frequency refers to how often a species occurs in different sample plots. A species may be densely populated in certain areas but not be present in many different locations, leading to high density and low frequency. This scenario can occur in localized habitats or microenvironments.
