Fig. 2. Housing density map and location of the 120 study gardens in Lauris, France. High-density housing type (built-up area < 20%) corresponds to the center of Lauris (T1); medium-density housing type (built-up area 10%–20%) corresponds to two residential areas close to the center (T2); low-density housing type (built-up area < 10%) corresponds to villas scattered in pine forest (T3a) or built on fallow land (T3b).
