Urban reforestation is the practice of planting trees, typically on a large scale, in urban environments. It sometimes includes also urban horticulture and urban farming. Reasons for practicing urban reforestation include urban beautification, increasing shade, modifying the urban climate, improving air quality, and restoration of urban forests after a natural disaster. In urban areas, improved air quality is important and trees reduce pollutants. This can be done since trees can sequester carbon dioxide. An increase in shade leads to lessened energy costs as sun is blocked from heating air conditioning using structures. With these benefits local property values can increase, rainwater pollutants can be filtered from the streets, improving water quality, as well as creating more space f
