OBITUARY: Michael Hough brought ecology to the cityscape

Mr. Hough, who died in January at 84, spent his career in pursuit of this ideal – the integration of cities with natural systems. As a young landscape architect in the 1960s, he helped lead that profession to combine urbanism and ecology, to think of human activity and nature as complementary and connected.
