Which component of urban forestry planning emphasizes maintaining a variety of species?

The component of urban forestry planning that emphasizes maintaining a variety of species is centered around species diversification efforts. This approach is crucial for building a resilient urban canopy, as it reduces the risk of widespread tree loss due to pests, diseases, or environmental changes that may particularly affect certain species. By promoting a variety of trees, urban forestry can ensure greater ecological stability and aesthetic diversity in the landscape.

Additionally, species diversification efforts can contribute to better habitat for wildlife and enhanced ecosystem services, such as improved air quality, stormwater management, and heat reduction in urban areas. This focus on variety helps cities adapt to ongoing environmental challenges, reinforcing the overall health and sustainability of urban trees.

While tree replacement policies primarily address the procedural aspects of removing and replanting trees, they may not inherently focus on the need for species variety. Similarly, actions to accommodate agents of change and information-education programs serve important roles in urban forestry but do not specifically prioritize species diversity as a central goal.
