Biol3250_Goldenrod_Height_Density_Data

The purpose of this experiment was to determine whether the height of Canada Goldenrod plants is correlated with their density. This dataset was gathered in the same location as the pilot lab. The Lumsden Ave. entrance to Taylor Creek Park has the most abundant population of goldenrods, compared to other entrances. This time the lab was conducted further into the shrubbery in order to get higher densities of goldenrods in the quadrats. Another trial was run closer to the trail to get lower densities of goldenrods. This was done to control the densities and determine the relationship between height and density. At each site fifteen 1x1 metre quadrats were marked off in a linear direction. The densities were measured by counting the number of individual plants in each quadrat. 0-3 plants were considered low density quadrats, 4-6 plants were considered medium density quadrats, 7+ quadrats were high density quadrats. The average height of plants was determined by averaging the heights of all plants in the quadrat. Both sites were visited on the same day. There were 2 main sites (N=2) with a total of 30 quadrats (n=2) distributed between them. The density and height data were recorded separately in order to ensure clarity. They will however be graphed together later when displaying visuals for the relationship between density and plant height.
