PROSPEK KONSERVASI TUMBUHAN DI AREAL NILAI KONSERVASI TINGGI PERKEBUNAN KELAPA SAWIT RIAU

Abstract

The purpose of the study was to analyze the prospects for plant conservation in high conservation value (HCV) oil palm plantations based on the sustainability value of plant species and population structure. The study was conducted in the HCV areas of three oil palm plantation companies and secondary forest in Riau Province. Data was collected by analyzing vegetation measuring 1.28-2.56 ha/plot in the HCV area and 3.84 ha/plot in secondary forest. Data analysis was carried out using relative density, and analysis of regeneration conditions were included in five categories (good, poor, fair, none, new). Data analysis related to the assessment of the prospect of HCV areas is carried out from the results of the analysis of the effectiveness of the HCV area and plant sustainability. The HCV area prospect assessment is grouped into three categories, namely prospective, moderately prospective, and not yet prospective. The results showed that the HCV area was not yet effective and the condition of important plant species was not sustainable. The HCV area has not been effectively assessed from the comparison of the value of the vegetation community between the HCV area and secondary forest, including low (<25%). PT A's HCV area in the form of forest has a higher effectiveness value than other HCV areas and secondary forest. The results showed that the most important plant species regeneration conditions were included in the none category (57.14%). This category shows that plant species are not yet sustainable because they are only found at one growth level, namely trees. So now it can be concluded that the purpose of the existence of HCV areas in maintaining and conserving plant diversity in oil palm plantations has not been implemented properly. Key words: Conservation of plants , High conservation value, Oil palm plantations, Vegetation analysis
