| Summary: | The riparian zone is a buffer zone between terrestrial ecosystems and river ecosystems. It plays an
important role in maintaining the quality of the river and the diversity of flora and fauna within the
ecosystem. The upstream area of Citarik watershed functions as a conservation area as well as a
water source for people living in Taman Buru Masigit Kareumbi (TBMK) area, West Java. The area
has an important value in being a part of the upstream river continuum of the Citarum River. At
present, the upstream riparian function of the Citarik watershed has decreased due to land
conversion. Therefore, various efforts are needed to maintain this area to prevent a declining quality
of the Citarum River. This study aims to determine the vegetation community structure and
ecological status of the upstream riparian of Citarik watershed. The study was conducted at the
upstream area of the Citarik watershed, TBMK, comprising of five sites which experienced land
conversion: site 1 (vegetable fields), site 2 (bamboo forest), sites 3 and 4 (deer cages 28 and 8
hectares), and site 5 (tourist area). Vegetation community structure was analyzed based on
Important Value Index (INP), Shannon-Wiener diversity Index, and Simpson Domination Index,
obtained from 6 nesting plots on each site (3 plots each on the left and right of the river). The
Riparian ecological status is determined by the QBR Index approach (Munne et. al., 2003) based on
the sum of scores from four aspects of assessment. This includes total vegetation cover, structure of
vegetation cover, quality of vegetation cover, and river channel alteration. Total score ranges from
0-100, which is divided into five riparian ecological status categories. Through this study, 8 species
of trees were obtained with the community name Pinus-Gigantochloa, 11 species of shrubs with the
community name Clidemia-Chromolaena, and 15 species of herbs with the community name
Ageratina-Molineria. The highest vegetation diversity index is found on site 1, which is the location
of land conversion to become vegetable fields. The Riparian ecological status in upstream Citarik
watershed, based on its QBR index is as follows; sites 1, 2, and 4 are of moderate quality, with
moderate disturbances (scores 60 - 65), and sites 3 and 5 are classified as poor quality with high
disturbances (score 50). |
