Relationship between abundance of grass and plant biodiversity in grasslands.

This dataset was retrieven from grassland samples taken in laboratory hours, with the help of a group member, as the other two were taking samples in the woodlots. Quadrats were placed randomly across the grassland, and then the number of species and its abundance was written down by me. We tried to prove that, when the abundance of grass grows, plant biodiversity decreases in general, due to competition of the grass with other species for the nutrients and other resources and to complete covering of the floor by it (impeding new outbreak of seeds of other species). Data seems to support this idea, but a more in-depth statistic analisys is needed.
