Landscape architecture was a form of architecture that focused on the art, planning, design, management, preservation and rehabilitation of the land and the design of man-made constructs.
In 2373, Richard Bashir was working in landscape architecture designing parks and public spaces. He loved working on projects that would be enjoyed by thousands of people long after he was gone, and thought of his creations as his legacy. (DS9: "Doctor Bashir, I Presume")
