Adinandra belukar occurs on land that has been degraded by agriculture and development, then subsequently abandoned. It reflects the common pattern of historical land use in Singapore over the years. The land of the Ridge has seen various types of uses. Prior to 1845, the area was probably covered by undisturbed lowland rainforest that now can only be seen in Bukit Timah. From about 1845 to 1945, the Ridge was covered by settlements and was used for rubber plantations. Some rubber trees still persist on the Ridge, and Holttum (1954a) reports seeing old and dying rubber trees along the Gap, where Buona Vista Road cuts through the Ridge. From 1945-1959, the plantations were largely abandoned, being unproductive after having exhausted the soil of its nutrients, and the primary land use was residential and military. From 1959-1970, the area used for residential purposes increased, and from 1970 to the present, the Ridge is largely known for housing the National University of Singapore campus. In addition, associated with the settlements and kampungs on the ridge were small-scale agricultural holdings, planting vegetables and fruits, e.g. tapioca (Manihot esculenta), sugarcane (Saccharum officinarium), banana (Musa paradisica), etc. Hence, some of these cultivated plants may have escaped into the Ridge vegetation. Horticultural plants, for example the Money Plant (Epipremum bipinnatum) are also present on the Ridge. The presence of the human settlements also resulted in settlers collecting wood for firewood, and this has caused some degree of damage as well.
