A broader diversity of trees is needed in our urban landscapes to guard against the possibility of large-scale devastation by both native and introduced insect and disease pests. Urban foresters and municipal arborists should use the following guidelines for tree diversity within their areas of jurisdiction: (1) plant no more than 10% of any species, (2) no more than 20 % of any genus, and (3) no more than 30 % of any family. Strips or blocks of uniformity (species, cultivars, or clones of…

As a consequence of compacted soils, impervious surfaces, heat irradiation, pollution, and other stresses, urban trees have an average expected service life of 10 to 25 years. Most public agency
Street Tree Diversity in Eastern North America and Its Potential for Tree Loss to Exotic Borers
TLDR
An analysis of tree inventories from 12 cities in eastern North America reveals an overabundance of certain genera of trees such as Acer and Fraxinus, and urban foresters should consider diversifying greatly the types of trees in cities.
Two Hundred Years of Forest Change: Effects of Urbanization on Tree Species Composition and Structure
Despite their importance, the dynamics of urban floras are not well understood and quantitative historical data are rare. The current study used three data sets for trees in Indianapolis/Marion

TLDR
The results suggest that improved street-tree management in lower‐income communities would likely positively benefit birds, and provide support for the high value of native street‐tree species and select nonnative species as important habitat for feeding birds.
Species Diversity and Preferred Attributes of Trees: A Case Study of the Private Urban Forest in the Greater Toronto Area
Healthy urban forests should have a diverse, native assemblage of species to support ecological integrity and reduce vulnerability to stressors. Since most urban trees are located on private
