 note = {application/pdf, Schima wallichii (DC.) Korth. (Theaceae) is one of the common mountain species native to Java Island which have role as host trees for epiphytic plants. To clarify the relation between epiphytic orchid diversity and S. wallichii tree as host, forty S. wallichii trees with diameter at breast height (DBH) more than 20 cm were chosen randomly and epiphytic orchids attached were counted and identified in a montane forest of Mt. Sanggara, West Java, Indonesia. Each epiphytic orchid grown point was divided according to the Johansson’s method which divides a tree stratification into five different zones (Johansson 1974), which are numbered from zone 1 to zone 5. Johansson zone 1 was omitted from the analysis because of no orchid there.
In total of 39 epiphytic orchid species, 1,731 individuals, were identified from forty host trees at the study site. Based on the species richness of epiphytic orchid attached, S. wallichii trees could be considered as an important host. S. wallichii trees DBH showed a positive effect on epiphytic orchid abundance (p<0.01), species richness (p<0.05), and diversity (p<0.05). There was significant difference in orchid abundance and species richness between trunk (zone 2) and crown (zone 3, 4 and 5) while no significant difference in them within crown zones. Tree size (DBH) and the number of branches positively affected orchid abundance and species richness in a host tree. Orchids were correlated positively in number with other vascular epiphytic plants at mid-crown (zone 4) and outer-crown (zone 5). Density of surrounding trees affected the orchids abundance negatively. S. wallichii trees are essential to epiphytic orchid community because they develop many branches for epiphytic orchids to colonize. Preserving the large crowned S. wallichii with low density of surrounding trees is effective for conservation of epiphytic orchids.
This thesis explores internal and external factors by SWOT analysis to formulate management strategies for orchid conservation in montane forests in West Java. From the SWOT analysis, several strategies were proposed to optimize the strengths and opportunities for the purpose of overcoming the weaknesses and to avoid the threats.
Consequently, the proposed strategies can be an alternative for stakeholder to manage this forest sustainably not only for local residents but also for the epiphytic orchid and their hosts., 本文/GRADUATE SCHOOL OF BIORESOURCES MIE UNIVERSITY, 102p},
