As autumn arrives in Lanark County, residents are treated to a stunning display of colourful leaves. But why do leaves change colour in the fall?
The process begins as daylight hours shorten and temperatures cool.
During the growing season, leaves are green because of chlorophyll, which helps trees make food through photosynthesis. As fall approaches, chlorophyll breaks down, revealing other pigments. Carotenoids produce vibrant yellows and oranges, while anthocyanins create rich reds and purples. These pigments help protect leaves from sun damage and may deter insects.
Different tree species contribute to the unique autumn landscape in Lanark County. Sugar maples, oaks, and birches showcase a variety of colours, making the region a popular spot for leaf-peepers.
As the days grow shorter, take a moment to enjoy the breathtaking views of Lanark County’s fall foliage. It’s a beautiful reminder of nature’s changing seasons and the science behind the colours we cherish.
