NESTED QUADRATS. Our first field trip was to North Stradbroke Island. Students spent the last few days of the trip studying terrestrial ecosystems on the island. Here a group of students collects data to construct a species-area cruve for the dune system at 18 Mile Swamp on the east coast of North Stradbroke Island. The cumulative number of plant species in a 0.25 sq. m. quadrat were determined. The size of the quadrat was doubled ten times until a 256 sq. m. quadrtat was reached, with the number of species at each stage recorded. These data were plotted and then compared with the data from a similar exercise carried out near Brown Lake, a large perched lake on the island.
