times in the same community. For best results in vegetation 

 analysis, the frequency index should be used in conjunction with 

 other characteristics such as population density, cover, weight, 

 height, periodicity, constancy, and fidelity. When time is limited 

 for field work, frequency and cover are particularly serviceable 

 in furnishing much information about the constituent species and 

 about the nature of the stands.
