The Citizen Science program seeks to better understand the benefits of residential wood ash on Muskoka trees and forests and to advance public awareness of the calcium decline issue by involving community members in the solution. FOTMW staff and board members began designing the Citizen Science program in January 2022 and it launched in April 2022. The program requires private property owners have safe access to at least two trees of the same species, similar size, and in similar growing conditions. The objective of the program is to compare metrics (measurements and observations) of a test tree (ash is applied) and a control tree (no ash application) over a period of at least one year.
