Abstract

The Cultivated Area in Kamojang Crater, Ibun District, Bandung Regency is part of a single landscape mountain, adjacent to conservated and protected areas which has high biodiversity. This study aims to identify invasive alien plants species in cultivated areas, adjacent to conservation and protected areas. The method used is a descriptive qualitative study with the sampling line transect in 500 meter radius of four location, namely near Nature Reserves (NR), near Nature Tourism Parks (NTP), agriculture (A) and near Protected Forests (PF), and this study has done up at July until November, 2022. The results showed that in the cultivated area in Kamojang Crater, Ibun District, Bandung Regency found 41 families and 96 species of understorey, with the highest number being from the Asteraceae, Poaceae and Fabaceae. Diversity of understorey was categorized as high (H'=3.428), evenly distributed (E=0.738), high species richness (R=13.503) and no dominant species (C=0.165). Several understorey, namely 8 orders, 10 families, and 29 species were categorized as invasive aliens plant species, with the highest important values index being Ageratina riparia (99,642%), Imperata cylindrica (72,919%), Paspalum notatum (31,155%), Chromolaena odonata (31,074%), Etlingera elatior (27,905%), Ageratum conyzoides (20,179%), Lantana camara (19,029%), Amaranthus hybridus (18,818%), Pennisetum purpureum (15,120%), Mimosa pudica (15,031%), Crassocephalum crepidioides (14,037%), and Axonopus compresus (10,671%).

Abstract

The birds have an important role in the cultivated areas Kamojang Crater, Cikaro subwatershed, Laksana Tourism Village, Ibun - Bandung District. The study aims to explore the diversity of birds and classified them in guild groups. The census method was carried out in June-November 2022, with a sample point count technique with a radius of 50 meters and a distance between the center point of at least 200 meters, observed in the morning (06.00-10.00 am) and afternoon (14.00-16.00 pm) at each point for 10 minutes. Located in cultivated areas were near  the nature reserve (NR), nature tourist park (NTP),protected forest (PF), and agricultural land (AL). The results showed that the birds are found 270 individu , 21 species, 7 ordo, dan 18 family. In general, the diversity of bird species in the Kamojang Crater cultivated area tends to be moderate (2,53), with a high abundance (4,09), birds species are equal in each location (0.80) and none dominate (0,11). The birds have higher Important Value Index in NR, NTP is Prinia familiaris (73,16 dan 53,58), in PF Lonchura leucogastroides (47,63), and AL is Apus Affinis (79,87). Birds found in cultivated areas near NR, NTP and AL are dominated by insectivore birds, while in the cultivated area near PF are predominated by granivore birds. According to the Similarity Index, bird communities in cultivated areas near NR have strong similarities with birds communities near NTP (62.5%, 76.92%, 29.71% and 63.06%).
