Method Being Compared| IS Value (2C/A+B)|
Plot method vs. Line method | 106+7=0.77|
The line-intercept method has more species than the circular plot method. The line-intercept method is useful for ascertain changes in institute communities, and the circular plot method is useful in determining the species diversity or species richness at the area...If you want to get a full essay, order it on our website: Ordercustompaper.com
