Abstract:
The designation of an area as a "high conservation value " (HCV) is a form of
concern for environmental management. The palm oil company is one of the business units
that has responsibility for the existence of HCVs in its area. This study aims to characterize
and analyze the components of vegetation and fauna in HCV in swamp areas in oil palm
plantations. The research object is in the form of vegetation and wild animals found in HCV
swamp areas. The equipment used is: a set of survey equipment, tally sheets, documentation
equipment, equipment for data analysis. Vegetation data collection is done using line transect
system. Data collected were the number of individuals and the number of species. Fauna data
collection is done by exploring and adjusting to vegetation data plots. Data collected were the
number of species found in each plot. Vegetation and fauna data were analyzed by using
tabulation matrix. Specifically for vegetation species and aves, the data were analyzed using
the Shannon-Wiener Diversity Index (H '). There are 8 types of vegetation in the HCV area.
The most dominant species found at this location at all levels of growth (seedlings, saplings,
poles and trees) is the Melaleuca cajuputi species. The dominant tree species was Melaleuca
cajuputi. The important value index of M.cajuputi > 90%. The H' value for all vegetation
levels are classified in the low category. The H’ values of trees, poles, saplings and seedling
are 0.84, 0.41, 0.49, 0.46, respectively. There are 16 species of undergrowth which are
dominated by plants associated with water. There were 21 species of birds at the study site, 4
of which were protected by government regulation PP No.7 / 1999. There are 21 species of
birds with a value of H '= 2.5. There are 8 species of mammals (including primates), 6 species
of reptiles and 3 species of amphibians. The existence of HCV is very important in
contributing to the diversity of homogeneous areas of oil palm plantations. Protecting HCV
swamp areas in oil palm plantations are very important for the availability of a conducive
animal habitat.
