What are street tree planting goals focused on?

The focus of street tree planting goals is primarily on utilizing all available spaces for planting. This approach is important because it addresses urban challenges such as aesthetic enhancement, air quality improvement, and the benefits of shade and cooling in urban heat islands. By planting in all available spaces, cities can maximize the number of trees, which contributes to ecological benefits and overall urban sustainability.

Choosing native species only can be a part of a broader strategy but is not the sole goal of street tree planting. The intent is often to have a varied planting strategy that includes species suited for specific locations and conditions, which can sometimes include non-native species that perform well in urban environments.

Maximizing tree height is not typically a goal in itself; rather, the objective is to establish a healthy urban canopy that offers various benefits including robust structure, longevity, and adaptability in the urban landscape.

Limiting species diversity is generally contrary to urban forestry principles. Instead, promoting diverse species is encouraged to prevent pest outbreaks and disease, contributing to the resilience of urban tree populations.

Thus, the emphasis on planting in all available spaces reflects a proactive strategy to enhance urban environments with comprehensive tree cover.
