Proposing local trees diversity for rehabilitation of degraded lowland areas surrounding springs

Soejono, Budiharta S, Arisoesilaningsih E. 2013. Proposing local trees diversity for rehabilitation of degraded lowland areas surrounding water spring. Biodiversitas 14: 37-42. This study was aimed to propose alternative trees diversity for rehabilitation of degraded lowland area surrounding spring. Data were collected by vegetation analysis of three sampling sites (1st. Cowek, 2nd Gajahrejo, 3rd Parerejo) to determine density, frequency, dominancy, diversity index and Important Value Index (IVI). The lists of plants in three sites were then compiled into an integrated list and used as reference for developing questionnaire. The questionnaire was then distributed to respondents who were chosen randomly. We recorded their preferences of tree species in rehabilitation program based on socio-economical and ecological aspects. Selected species were then proposed as alternative plants for rehabilitation of degraded spring area based on landscape topography and remaining vegetation coverage. The results showed that species diversity of Moracecae family was the highest than other families. In term of ecological aspect, Ficus racemosa, Artocarpus elasticus, Bambusa blumeana, Dendrocalamus asper, Gigantochloa atter, Ficus benjamina, Syzygium samarangensis and Ficus virens showed high Important Value Index. On the other hand, based on socio-economic aspects, Ficus benjamina, Artocarpus elasticus, Artocarpus altilis, Artocarpus altili
