This study investigated the inter-relationshep between diversity of tree and bird species existed in urban forest of Bandar Lampung City. The objectives of the study on Tree and BirdSpecies Diversity in Several Urban Forest Area of Bandar Lampung City are to know a) tree species diversity composition in urban forest vegetation, b) bird species diversity, and c) the correlation between those both components. The study conducted on six areas of urban forest in Bandar Lampung City. Tree sampling was measured within plot line having 20 m x 20 m size, while bird observation was done using direct watching method which was performed every morning (06.00 ~08.00) and evening (16.00 ~ 18.00) during tree days for each urban forest area. The biodiversity parameters used in this study are Margalef Species Richness Index, Shannon Biodiversity Index, and Modified Hill’s Ratio Index of Evenness. In all urban forest areas of Bandar Lampung City wasidentified 45 tree species (24 families) with index of species richness 6.22, index of species diversity 2.92, and index of evenness 0.60. Compared to closest natural vegetation (of Wan Abdul Rachman Provincial Park) the vegetation is very different (index of similarity 0.13). The study concluded thata) urban forest vegetation of Bandar Lampung City are generally dominated by domesticated species, 2) 24 birds species (16 families) were identified in all of urban forest area of Bandar Lampung City, and c) there is positive correlation between the tree species diversity and bird species diversity in urban forest of Bandar Lampung City.

This research aim to establish a land use change model purposed to figure a spatial ecological equilibrium out from the land used activities. The analyzing of these land use change impacts were adopted from modeling methods, based from system thinking approach. Although the analytical constructions dominated by social sciences, all methodologies were drawn from more than one field of discipline to analyze the nature-society-economy relationships. These interdisciplinary orientation combining concepts has some advantages in recognizing most complex variables in the real world than another functional approaches. The model has verified to validate in villages around the HTI concession area of Jambi Province which is managed by PT Wirakarya Sakti (WKS), and resulted some behavior patterns of land use changed that showed in descriptions as a whole. At last, sensitivity analysis of this model - like a game - has developed the “what if” input variables to predict situation of the future, and has resulted some options of scenario as decision support to the policy system framework.Keywords: Ecologycal equilibrium, HTI pulp concession area, land use change, modeling, system thinking approach, decision support system, Jambi.

The species composition and forest structure of Taman Hutan Raya Bukit Soeharto - East Kalimantan were investigated using transect method through systematic sampling with random start design. During data collection,5 transects of 20 m width and 1 km length of each in Wanariset Semboja forest complex and 10 transects in Pusrehut UNMUL and Protection Forest areas were established. The study shows that species richness of trees in those three forest complexes are relatively similar, however, the regeneration stage in Pusrehut UNMUL forest complex is relatively higher than those in another two areas. Medang (Litsea firma), Acacia (Acacia sp.), and Mahang (Macaranga gigantea) are dominant tree species in Wanariset Semboja, Pusrehut UNMUL and Protection Forest areas, respectively. Mahang (M. gigantea) as pioneer species is also commonly dominated forest regeneration in Taman Hutan Raya Bukit Soeharto. Based on tree’s diameter distribution, those forests show balanced uneven-aged forests in which the large amount of trees are concentrated in the height class of 10 to 29 m. Species diversity of those forests are relatively high (H > 2.5) either for seedling, sapling, pole or tree growth stages, however, those forests show different plant communities (IS < 70 %).

Lhuing the times of the census 1974 - 1981 the Bali mynah population steadily increased, but from 1983 - 1986 it has steadily decreased. At present the population of the Bali mynah is declining at an alarming rate, so it needs a realistic conservation programme designed to enhance the survival of this species. The population decline is related to the environmental resistance, such as : illegal hunting, forest fine, and habitat destruction due to human pressure.

Kajian Ekologis Rafflesia Patma Blume di Cagar Alam Leuweung Sancang Jawa Barat Dadang R Priatna; Ervizal A. M Zuhud; Hadi S Alikodra

Rafflesia parma Blume is one of the 12 Rafflesia spp. found in Indonesia which has an attractive and relatively big flower and a unique life. As a holoparasite, this astonishing plant is particularly dependent on the distribution of, and its interaction with the liana host, Tetrasfigma sp.The distribution of R. patma is confined to the Leuweung Sancang Nature Reserve, the Pananjung Pangandaran Nature Reserve and the Nusa Kambangan Nature Reserve. The people in Java andKalimantan have been utilizing Rafflesia for traditional bio-medicine (such as for the raw material of jamu "patmosari") since a long time. However, illegal harvesting of the buds seem to ignore the sustained yield principle. Without any protection measures, this will lead to the extinction of the endemic plant species in the near future. The important components of R. patma habitat are described in this paper, among others are its association with the tropical rain forest, the characteris'ticsof the liana host, the pollinator and seed disperser and some aspects of the abiotic components.

Significant impack resulted from the reclamation of mangrove forests, will result in its dissappearancel functional changes which in turn will affect the sea productivity of Jakarta Ray and itr other functions such as wildlife hahitat, protection against waves and winds, ahsorption of pollutants in Jakarta Bay, and sea intrusion,also the dissappearance of nature potentials to he develop as nature recreation and tourism site. Efforts should include maintenance, restoration and development of Jakarta Bay mangrove forests, especially in Muara Angke Nature Strict Reserve and the Protected Forest along the eastern part of the coast.

The proboscis monkey (Nasalis lavartus ) is a member of sub-family Colobinae, and a sexually species, endemic to Kalimantan. The habitat of the monkey in confined mainly to mangrove, riverine forest and peat swamp forest. Habitat degradation in major factor which disturbe the population of this species. a Habitat, Koala Samboja has undergone a lot of disturbances, especially bby various activities of the people who are inhabiting this area. The aim of the study was to know some ecological parameters, habitat, population and behavior of the proboscis monkey. The study was done at River of Koala, Samboja, East Kalimantan.

lndonesia is categorized as one of the biodiversity centers in the world. The value of biological diversity as environmental, economic and social resources for maintaining the integrity and sustainability of natural systems and human life is very important. But, in other side, human development and thepopulation increase have caused the high rate of extinction of various plant and animal species. This high rate of extinction calls for a very serious and prompt action of conservation. Priority should be given to designing protected area for protection of species and ecosystem. Quantitatively, conservation development programs of Indonesia have a great achievement by designating 385 protected area which covering 22 560 545.46 ha. This paper overviews the development of protected area in lndonesia including systems, history, existing distribution, problems and obstacles, and government policy.
