A Simple Method to Estimate Benthic Populations of a Small Woodland Stream
The stream bottom is stratified into different substrate types and each substrate is sampled separately. The area of each substrate and the sampling site is measured. This allows a more accurate estimation of the ecological density of a benthic species as well as its crude density.
