Distribution of Casuarina equisetifolia along the Southern Coast of Yogyakarta after Sixteen Years (1996-2012)

Distribution of Casuarina equisetifolia in Indonesia based on the examination of Bogoriense Herbarium specimen were Islands of Sumatera, Kalimantan, Sulawesi, Moluccas, Java, and Lesser Sunda. Recently C. equisetifolia had also been spreading with the aid of people into Parangtritis sand dune and 27 beaches in 21 coastal villages (65.5%) along the southern coast of Yogyakarta. Their locations and plantation patterns clarified by using exploring method and Google Earth reference images. Five plantation patterns were depicted i.e. oblique comb, untu walang, rows formation, individual, and rectangle. The first two constitute the early pattern, but not currently replicated. The largest numbers of rows formation and rectangle, which were established between fore-dune and landward in Bantul and Kulonprogo, proved associated with agricultural land. In individual, C. equisetifolia had been distributing in roadsides, yard of fishing villages, and tourism beaches as shady tree and greenery landscape.  [full paper]
