A comparison of different sampling methods of quantitative vegetation analysis.

Abstract

Percentage Cover Scale, Graphical Method, 2 Point Quadrat Methods, the Five Nine and Twelve-Class Cover Scales and Biomass Harvesting were used in estimating abundances of ground vegetation in clear-cut areas and on an abandoned field. Results are examined with the help of DCA ordinations. Species numbers and diversity indices obtained by different sampling methods are compared. There were no large differences in DCA configurations between the sampling methods, but different sampling methods did not give similar estimates of species numbers and diversity indices.-from Authors
