Abstract

The understorey functions as a ground cover that maintains moisture so that the rapid decomposition
process can provide nutrients for the main crop the nutrient cycle can take place perfectly, the
avalanches that fall as litter will be returned to the tree in the form of nutrients which, as is known, will
be broken down by bacteria and microbes. This study aims to determine the type, number, and
presence of each understorey in the area of the Samarinda State Agricultural Polytechnic Forest
Management Study Program, precisely behind the Silviculture Laboratory. The research method used
a single plot measuring 60 m x 32 m with sub plots measuring 2 m x 2 m which were arranged
systematically so that there were 480 sub plots.The results of the study found as many as 23 species
of understorey which were included in 22 genera, 18 families, as many as 14.616 individuals, in
1.528 attendances. The most common species found were Asystasia intrusa as many as 5.728
individuals with distribution in 304 plots, then Clidemia hirta (L.) D.Don with 1.864 plants with
distribution in 240 plots and Stenochlaena palutris (Burm.f.) Bedd species. as many as 1.344 with a
distribution of 56 plots. While the types of Alpina sp and Imperata chylindrica as many as 8 plant in 8
plot.
