Abstract

After being observed as a whole, Gunung Gede Pangrango National Park has a high diversity of Ferns. This research aims to describe Ferns in the Ciwalen Gunung Gede Pangrango National Park, so it is hopefully could describe the diversity of ferns in that path. The Inventory of ferns is done by using exploration method with random sampling technique which then identified with General Key to Malayan Fern referral. The results of this research showed that there are ten types of ferns that have been founded in the Ciwalen Gunung Gede Panggrango National Park, such as Sphaerostephanos sp., Asplenium truncata, Nephrolepis davallioides, Botrychium daucifolium, Selaginella opaca, Huperzia phlegmaria, Equisetum ramosissimum, Didymochlaena truncatula, Hymenophyllum sp., and Diplazium poliferum. Features any distinctive Ferns can be seen from the form such as  rhizome, type of  frond, an accessory, the sorus, habitats that were found, and others.

Abstract

Urban birds represent the group of organisms adapted to environments characterized by close proximity to human activity. However, disturbances often displacing them to less disturbed habitats. In Jakarta, city parks and cemeteries serve as relatively low-activity green spaces that provide potential refugia for avian communities, thus hold conservation value. This study investigated bird and vegetation diversity in these two types of urban green open spaces (GOS) and examined their relationships the vegetation diversity. Surveys were conducted in four city parks and four cemeteries in circular plots. Results indicated that bird diversity in city parks was moderate, while tree and non-tree diversity ranged from low to moderate. In cemeteries, bird, tree, and non-tree diversity were consistently low to moderate. It is a positive correlation between tree diversity and bird diversity, and a negative correlation between non-tree diversity and bird diversity, though both relationships were not strong. It is also revealed that bird diversity in both city parks and cemeteries differ markedly. These findings highlight the ecological role of urban green spaces in supporting avian diversity and emphasize the importance of vegetation structure in shaping bird communities within highly urbanized landscapes.
