Using quadrats to estimate population size of plant species

A worksheet that provides secondary data from an investigation into the population density/abundance of plant species in a field. The worksheet requires some calculations to estimate population density and total population size across the whole field. There is also consideration of the reasons why quadrats are always deployed randomly and why random sampling is required for any fieldwork investigation.
