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.
