How are Nova Scotia’s trees faring in a historic drought? Here’s what the experts say

Nova Scotia’s trees are facing worsening conditions due to the parched summer the province has experienced, experts warn. With little to no rain in the forecast, concerns are growing for the health and stability of the trees.

Peter Duinker, a professor emeritus at Dalhousie University, explains that newly planted or naturally regenerated trees are especially vulnerable to drought as they are small and still establishing themselves. The Canadian Drought Monitor reported drought conditions across the entire province by late July, and there has been minimal rainfall since then.

In Halifax, Crispin Wood, manager of urban forestry, has observed some of the city’s recently planted trees struggling in the dry conditions. Some trees are losing their leaves prematurely, affecting the vibrant colors typically seen in autumn. While Wood believes there may not be significant tree mortality, he anticipates a less colorful fall season.

Scott Holman, urban forestry supervisor for the town of Truro, highlights the impact of the drought on tree roots, making them less stable and more susceptible to toppling over. With the Atlantic hurricane season peaking in late August and September, maintaining tree health is crucial to prevent damage during strong storms.

Truro has taken steps to care for trees during the drought, including using watering bags to provide a slow release of water to the root balls. Planting trees that are more resistant to adverse conditions is also being considered as a long-term management strategy. Wood emphasizes the importance of selecting tree species that are better adapted to drought conditions.

As climate change continues to impact weather patterns, researchers like Duinker stress the need for more studies on how trees will be affected by long-term climate change and severe weather events. Understanding the resilience of trees and their root systems is essential for preserving green spaces and urban forests in Nova Scotia.
