The study sites in Ho Chi Minh City.
The six major parks and their adjacent residential areas in the central part (urban area) of the city. The distances of 250 m, 500 m, 750 m and 1,000 m from the park boundary were shown in the residential areas. The base map was adapted from an open source map retrieved on Natural Earth Data at http://www.naturalearthdata.com/about/terms-of-use/.
