DIVERSITY OF UNDERGROWTH IN AREN (ARENGA PINNATA MERR.)

Abstract

The condition of plant communities is closely related to various factors contained in an area such as edaphic, climatic and biological factors. The composition of the planted area is strongly influenced by the composition of plant species, dominant species, density and state of canopy closure. Plants that grow in hilly areas with relatively high and evenly distributed rainfall throughout the year. In South Kalimantan this species grows around people's residences and plantation areas. Sugar palm plantations (Arenga pinnata Merr.) have a fairly humid environmental condition and at the top of the garden will be very rich in various types of undergrowth so it is very interesting to make an inventory of both species and diversity. By using vegetation analysis that makes several sample plots with a size of 1m x 1m in a large plot of 10m x 10m so that they can represent the research location. Observing all types of undergrowth and documenting each type so that its diversity index and dominant nature can be known. The results showed that the number of P species in question was 17 species from 11 families, with several dominant species such as Litu (L. scandens), Cambai (P. baccatum Blume), Magatseh (P. polyneura) and (P. pubinerve) as well as the Diversity index value (H’) of 3.39.
