We explored the drivers of lichen taxonomic diversity and lichen abundance on
wooden trailside benches within the city of St. John’s, Newfoundland and Labrador, to better
understand lichen colonization of wooden structures. We examined three variables including
the age of each bench, the distance of each bench from the nearest tree with lichens, and the
distance of each bench from the nearest road. Multivariate analyses and model selection using
AIC revealed that bench age and distance from the nearest tree with lichens together was best
at explaining the sample data. Age of the benches was of greatest significance for predicting
both lichen diversity and abundance. Understanding factors that drive the distribution and
colonization of species across urbanized landscapes is important for conservation efforts and
for preserving biodiversity in the future.
Key words: colonization time, urban substrate, wood, microclimate, air quality, park,
substrate age, source population.
