Trees in urban areas may improve mental health Doctors prescribe fewer antidepressantsin urban areas with more trees on the street, according to recent UK research. This male cultivar of Ginkgo is practically pest-free, resistant to storm damage, and casts light shade due to the narrow crown. Increasing urban green spaces will help to mitigate a city’s already existing poor air quality, which can oftentimes be so poor that it adversely affects the population. Approximately 80% of the U.S. population lives in cities. The tree tolerates pollution and drought. The small stature and vigorous growth of hedge maple make this an excellent street tree for residential areas or perhaps in downtown urban sites. We have found that native plant species can become established and persist even on poor urban soils. Site Selection: The third step is to select the exact plant site with the following considerations: (i) … Even small “pocket parks” can brighten communities. If you run an online search for images of biodiversity, you are likely to find lots of photos of tropical rainforests and coral reefs. Gleditsia tricanthos var. Advantages of Urban area
Good transport facilities are available … Trees and landscaped areas absorb particles in the air that would otherwise pollute the atmosphere. Our research group has studied these impacts on patches of land where buildings once stood. With the number of green spaces in our cramped urban areas at a premium, moving shrubs and trees onto buildings is one way to ensure this essential process keeps going around us. Bur Oak has been chosen an "Urban Tree of the Year" as determined by responses to an annual survey in arborist magazine City Trees. Humans also modify dispersal patterns. In urban areas where the human population has changed the landscape, green initiatives need to be put in place to help the other local populations survive. Unlike many traditional landscape plants, spontaneous urban plants can also colonize disturbed bare ground, help with erosion control and slope stabilization, and be used as food and habitat for wildlife.
