What does the term Vigor refer to in the context of urban forestry?

In the context of urban forestry, the term Vigor refers to the overall health and capacity of a tree to resist stress. This includes the tree's ability to grow, develop, and sustain itself in an environment that may present various challenges, such as pollution, soil compaction, drought, and pests. A tree exhibiting high vigor tends to have robust growth patterns, healthy foliage, and a strong root system, which together enable it to adapt to its surroundings more effectively.

Vigor is a critical factor for assessing the resilience and longevity of urban trees, as it directly impacts their capacity to thrive despite the potentially harsh urban conditions. By monitoring and enhancing tree vigor, urban forestry efforts can improve canopy cover, support biodiversity, and contribute to the overall health of urban ecosystems.
