recall the use of quadrats to estimate the population size of an organism in two different areas
• The sand dune ecosystem: it is made up of a number of different species of population which form the community of the ecosystem (and the habitat).
• There is a fence that splits the area in two: an ungrazed area and a grazed area (grazed by cattle and agriculture).
• quadrating: counting the size of a population.
• The quadrat is a square (0.5mx0.5m) and used to sample different areas of the land, and gain an estimate of the populations size.
• This way populations between two different areas can be compared.
