Trees play a vital role in improving urban environments; namely by reducing air pollution, increasing biodiversity and providing shade, therefore, mitigating the Heat Island Effect, plus countless other benefits.
With dense underground utilities, impervious paving and asphalt, and compacted urban soils, city streets can be a hostile habitat for trees making it a challenge for them to prosper in built environments.
Trees require space and soil volume to thrive. The capacity of soil accessible to the tree is a critical factor in successfully growing and nurturing trees in urban landscapes. We know mature, larger trees produce greater benefits, yet to allow larger trees to develop we need to provide larger volumes of soil for roots to flourish.
