Importance of Household Decisions

Research in Phoenix, Baltimore, and Boston revealed that household decision-making and income shape patterns of plant and bird diversity in residential landscapes.

Mapping Urban Lands

BES scientists have pioneered a new system for classifying the diverse land types in urban areas. This groundbreaking land classification system more accurately reflects ecological processes in cities and suburbs and better predicts potential changes in water quality and bird diversity — strengthening the toolbox for urban land managers.

Perceptions of Justice

Contrary to popular perception, Whites in urban Baltimore are more likely than African-Americans to live near facilities that pose health risks. A long history of segregation denied African-American residents the advantage of living close to workplace factories that may now expose those close by to toxins.

Islands of Green

BES scientists have found that cities are more biologically diverse than commonly thought and that large green spaces, small parks, yards, and vacant lands shelter new species of soil invertebrates, rare plants, and significant bird diversity. These studies underscore the importance of maintaining islands of green in urbanizing landscapes.

Urban Watersheds

BES scientists discovered that urban watersheds retain substantial amounts of nitrogen, an important water pollutant, and prevent it from flowing into downstream waters. This finding underscores the valuable service that green spaces in cities and suburbs provide by safeguarding water quality and protecting coastal waters.
