Rehabilitation activities have already been implemented in Indonesia more than a century since colonial era. Similarly, the Government of Indonesia has adopted a programme to rehabilitate degraded forest and lands (Rehabilitasi Hutan dan Lahan-RHL) since 1951. Furthermore, the government gave more serious rehabilitation initiativesafter major flooding in 1966 in Solo, central Java Province.

Wanagama is one successful forest rehabilitation which is located in Gunungkidul Regency, Yogyakarta Province, Java Island.  The project was initiated by scientists of Forestry Faculty, University of Gadjah Mada since 1968. Most of the techniques of rehabilitation conducted for restoring the degraded forests by planting tree species, such as Tectona grandis, Swietenia mahagoni, Melaleuca leucadendron, Paraserianthes falcataria, Acacia auriculiformis, and  Pinus Merkusii.

After many years of forest rehabilitation activities, however, few studies have investigated the diversity of organism (i.e. bird and plant species). Therefore, this PhD project, we are focusing on two main studies:

1. to find out the effect of rehabilitation year and tree species on herbaceous vegetation composition and diversity at the forests, Yogyakarta Province.

2. to find how the number of bird species, their population size and proportion endangered species vary with bird traits, land degradation, size of island, distance to mainland or larger island, distance to Asia and Australia, and glaciological (whole areas of Indonesia).
