Milkweeds density and abundance by location

This experiment compared the density of the milkweed plants in middle of the grasslands at York University compared to the edge. The edge was defined as anything 5 m or less from the boundary of the grassland. Anything found greater than 5 m from this 'boundary' was defined as the middle. We randomly placed 40 quadrats (20 in the middle and 20 on the edge) and measured the heights of all the milkweeds present in this vicinity. The density as well (per m^2) was also recorded.
