About
Eucalyptus urophylla, commonly known as Timor white gum, Timor mountain gum, popo or ampupu, is a species of eucalypt native to islands of the Indonesian Archipelago and Timor.
It is also common in other countries with humid and subhumid tropical climates where it is grown as plantation timber.
Where it grows
The species is native to the Lesser Sunda Islands of Indonesia. It has a scattered distribution in south eastern areas. It has a scattered distribution and is known on seven islands in total; Adonara, Alor, Flores, Lembata, Pantar, Timor and Wetar. It has a natural range of around 500 kilometres (311 mi). E. urophylla has an elevation range from sea level up to around 3,000 metres (9,843 ft). It is endemic to monsoonal areas with two to eight dry months per year. It can tolerate nutrient poor soils that are damp and well aerated. Most of the soils it is found in are volcanic in origin. It often dominates in open, usually secondary montane forests where it is found on mountain slopes and in valleys. It is often found in soils based on basalt, schist and slate but rarely round limestone.
