Redlining was pervasive in American cities from the 1930s through the late 1960s. Maps were drawn specifically to ensure that Black people were denied mortgages. These discriminatory practices created a lasting legacy of economic and racial inequality which persists today.
Less obvious is how redlining has shaped nature and the urban ecosystem. A recent study found that previously redlined neighborhoods in Baltimore have fewer big old trees and lower tree diversity than other parts of the city. These findings are part of the Baltimore Ecosystem Study, a collaborative research project which has tracked the city’s changing urban environment for the past 25 years.
