The large Itremo massif is divided administratively into 3 different communes (kaominina): Itremo Commune, Mangatabohangy Commune and Amborompotsy Commune. Below, the localitites located in Itremo and Mangatabohangy Communes are listed.
A large part of the massif, an area of 273 km² has recently (2003) become an protected area due to its many diverse and rare plants.

" In Ambatofinandrahana there is a number of quartz localities (thousands of quartz veins) but majority of specimens in this area are mined vicinity of Itremo village. This big village is situated just before entering to scattered Itremo Massif - metamorphosed sedimentary rocks, which today are quartzites and marbles. In this massif there are thousands of quartz veins (hydrothermal low temperature) with very varied quartz crystals. In some veins there is simple rock crystal (crystals up to 70 cm), in others there are so-called pineapple quartz. Some veins contain quartz with bubbles, hollandite or inclusions of a greenish micaeous mineral.
People from Itremo make irregular mining in their neighbourhood (around 15 km). Other areas of Itremo Massif are almost completely unexplored.
Majority of quartz from Madagascar (even if not labelled like this) is from Itremo massif". Tomasz Praszkier commentary see
