 An alternative,​ rapid approach to estimating species richness is to use the observations made along line-point intercept transects. Species richness is estimated as the number of species encountered over all of the point intercepts made in a given area (i.e., across all transects). This method is much quicker than the Modified Whittaker approach, but will tend only to capture the most common species in the area.  An alternative,​ rapid approach to estimating species richness is to use the observations made along line-point intercept transects.
