Height
Measured in
centimetres
# of leaves
Number of leaves visible attached.
# of flowers
Number of flowers recorded if visible.
Degree of Crowdedness
0 = open, 1= some plants
nearby, 2 = quite a few and 3 = very much crowded bunch of plants within
50cm, regardless of species.
Methods
Description: On Wednesday, September
21st, 2016, at
roughly 2:50 pm, with sunny clear skies, data was collected. Data was
collected at the York University grasslands.
A
transect tape was elongated to 25 meters and then placed along the grassland.
Each time the species was spotted with the naked eye touching the transect, its
properties were recorded as displayed on the excel spreadsheet.
Variables
are explained by the meta data. At
random, one leaf was chosen from the species, stretched to its full length
and measured by another measuring tape in centimetres.
Then,
all of the leaves attached to the species were counted. Number of flowers
were recorded if seen. Lastly, how crowded the patch was, was recorded from 0
to 3.
Numbers
are explained by the Meta data, this means that if the
grass is all the way around the species, degree is 3. This process was
repeated for a number of 50 individuals. The numbers from 0 to 3 are huge indication if the grass abundance is high or low and dry and aid identifying patterns.
Common
name for the species is known as Dandelion, scientifically known as Taraxacum officinalis.
