In recent years, researchers have discovered a strong correlation between neighborhood income and tree canopy cover. 
urbanization is the cause of urban heat island a condition that could be described as The modification of land surfaces how does this island affect the animals? For example, ant colonies in urban heat islands have an increased heat tolerance at no cost to cold tolerance, and Grey-headed flying foxes, found in Melbourne, Australia, colonized urban habitats following increase in temperatures there. does it change according to the season? Yes, the urban heat island temperature difference is not only usually larger at night than during the day, but also larger in winter than in summer.

Urban heat island [SEP] Inequality of tree canopy cover
In recent years, researchers have discovered a strong correlation between neighborhood income and tree canopy cover. In 2010, researchers at Auburn University and University of Southern California found that the presence of trees are "highly responsive to changes in [neighborhood] income." Low-income neighborhoods tend to have significantly fewer trees than neighborhoods with higher incomes. They described this unequal distribution of trees as a demand for "luxury," rather than "necessity." According to the study, "for every 1 percent increase in per capita income, demand for forest cover increased by 1.76 percent. But when income dropped by the same amount, demand decreased by 1.26 percent." Trees are a necessary feature in combating most of the urban heat island effect because they reduce air temperatures by , and surface temperatures by up to .
