"While most of the botanical community concentrates on tracking the threats to biodiversity in the tropics," the Brooklyn Botanic Garden is conducting research on the biodiversity found in the urban landscape. The Web site includes useful resources for users interested in identifying, planting, maintaining, or just learning about the plants found in urban areas. The Web site is easy to use, with ample explanations and a glossary of terms. Although the research is focused on the New York metropolitan region, much of the information may be useful in other parts of the country.
