Urban forestry is practiced by municipal and commercial arborists , municipal and utility foresters, environmental policymakers, city planners , consultants, educators, researchers and ...
Urban forest inequity, also known as shade inequity or tree canopy inequity, [1] is the inequitable distribution of trees, with their associated benefits, across metropolitan areas. [2] This phenomenon has a number of follow-on effects, including but not limited to measurable impacts on faunal biodiversity and the urban heat island effect .
Ecologically motivated research into genetic modification is underway.

Specific diseases have reduced the ...
living on a street with 10 more trees than average (both on the street and in backyards) makes you feel as healthy as if you were seven years younger.

Genetic diversity is needed to maintain the vitality of forests and to provide resilience to pests and diseases. Genetic diversity also ensures that forest trees can survive, adapt and evolve under changing environmental conditions. Furthermore, genetic diversity is the foundation of biological diversity at species and ecosystem levels.
