Arbor Day 1920, Garden Prairie School, Saskatchewan

Arbor Day Origins

Arbor Day was recognized as early as April 10, 1872. On that day, American journalist and politician J. Sterling Morton founded Arbor Day as a means of promoting conservation and correcting the gradual deforestation of the prairie. In his words, what sets Arbor Day apart from other holidays is that while other special days commemorate the past, Arbor Day celebrates the future. Read more about Arbor Day's origins here.

History of Arbor Day in Saskatchewan

For many years within the province an annual spring observance occurred that involved most schools, many community groups and municipalities, and concerned individuals. The day was marked with the planting of trees, the cleaning up of yards, streets and alleys, choosing and protecting a particular area of natural habitat and generally celebrating our dependence upon nature and specifically trees.

In 2019, the Yellowhead Flyway Birding Trail Association (YFBTA), an affiliate of Nature Saskatchewan, began working toward the province proclaiming and publicizing an annual spring Arbor Week. The Government of Saskatchewan officially proclaimed May 22, 2020 as Arbor Day and May 17-24, 2020 as Arbor Week.


Arbor Week: May 28th to June 6th, 2021

SOS Trees Coalition in partnership with many community organizations including the Meewasin Valley Authority, University of Saskatchewan and the City of Saskatoon hosted Arbor Week 2021, an opportunity for individuals and families to learn the "how to" of planting trees, the benefit of trees and the joy of spending time in them. Our theme for the 2021 Arbor Week was "Resurgence".
