Fungi play a vital role in the decomposition of organic matter and the transformation of
key nutrients (Starke, 2020). Although fungi have a crucial place in ecosystem dynamics, factors
which influence species distribution patterns are poorly understood (Tedersoo, 2014). This study
aims to better understand how light affects fungi growth in coastal temperate forests. In this
study, fungi growth was observed at the Botanical Garden at the University of British Columbia
(UBC). Data was collected and used to calculate the mean number of fungi and average light
intensity at four different locations (North, South, East, West) from the center of Wharton Glade.
It was found that the highest mean number of fungi were in the southern quadrant, which had
medium light intensity (2100-6300 lux). This finding is contradictory to contemporary research
on this topic which identifies that fungi typically grow optimally under low light conditions
(Idnurm, 2005; Simon, 2013). A potential source of error was generalizing a variation of fungi
species as “fungi”. Moreover, fungi species were counted one month prior to the measurement of
light intensity. Future research on this topic should consider the effect of other abiotic factors on
fungal growth such as soil pH, moisture, temperature, and season.
