Determination Of Minimum Quadrat Size For The Herbaceous Vegetation: A Case Study Of Durpang Reserve Forest, Arunachal Pradesh, India

Abstract

For the field vegetation survey, we used the Random sampling method which is an important approach. However, sampling survey in forest areas is difficult because determining an appropriate quadrat size that represents the unevenly distributed vegetation. In this study, we determined the minimum size of the quadrat only for herbaceous vegetation by applyingthe species area curved method which is an important method for the prediction of species richness in terms of habitat area. Using the species area curved method; we simulated random sampling and analyze minimum to maximum diversity. The size of the quadrat in which maximum diversity of species can be recorded is called the minimum size of quadrat for that area. Our result shows that 60×60 sq. cm size are the most representative for sampling survey of herbaceous vegetation in this location.
