As winter begins to loosen its hold, subtle signs of seasonal change emerge across the landscape. One of the most telling is the appearance of “thaw circles” — rings of melted snow that form around the base of trees. These patterns occur as darker tree bark absorbs the sun’s energy more readily than the surrounding snow, radiating heat outward and creating distinct openings in the snowpack.
These circles are often strikingly defined, sometimes resembling clean, circular cutouts. While similar features can be seen around conifers where branches limit snow accumulation, they are especially noticeable in deciduous forests as the late-winter sun grows stronger. Even when air temperatures remain low, these small openings signal that the ground beneath is beginning to warm and reawaken.
Beyond their visual interest, thaw circles play a quiet but important role in early spring. They create pockets where sunlight reaches the soil sooner, allowing early plants to emerge before the forest canopy fills in. In this way, they offer both a glimpse of the earth below and a natural indication that the seasonal transition is underway.
A Memorial Tree Planting is being planned in Mulmur, Ontario
This sense of renewal was evident last week during a visit to the Township of Mulmur, where plans are moving forward for a living tree memorial honouring Maple Leaves Forever founder Ken Jewett. Several native maple trees will be planted in a municipal park in Mansfield, creating a lasting tribute that reflects Ken’s vision and commitment. A gathering to mark this installation is planned once planting is complete, and further details will be shared in the coming months.
Happy Spring, one and all!
