P4C Tree Remeasuring at Humber Arboretum

Thank you to the Humberwood Youth Group from the Toronto Public Library for volunteering their time to remeasure the trees in the Planting for Change Plot and our 2nd Biodiversity Experimental Plot at Humber Arboretum (behind Humber College North campus). The 2nd Biodiversity Experimental Plot contains Sycamore and Yellow Birch trees provided by three different nurseries located at different latitudes in Southern Ontario. The goal of this experiment is to compare their growth in Toronto (located in an urban heat island that is about 4 degrees Celsius warmer than rural Ontario) to the growth of the same tree species planted at the nurseries located in St. Williams, Dunville and Milton.

Data and photos will be posted soon under the Planting for Change program and the Let’s Plant, Measure and Mulch program.
