Abstract

Galunggung Mountain forest area in West Java of post eruption 1982 may served as a natural laboratory for studying plant development and plant growth, including pine trees. Pine trees that were planted by Perhutani at Galunggung had high prospect although they were planted at degraded areas and poor nutrient. Experimental plots were set up in two different locations at Mount Galunggung. Trunk diameter, tree height, total height, soil humidity and soil pH was measured for all pine trees inside the plot at each subplot. All measured parameters resulted in varied values with varied deviation standard. Measurement of trunk diameter, branches height and total height of pine trees in Mount Galunggung suggested that their growth rate was slow and no significant correlation among them.

Abstract

The research was conducted to study the structure and composition of herbaceous and seedling communities (understorey species)occurred on herbivore habitat within Cikepuh wildlife sanctuary. A series of 25 plots of 1 m x 1 m each with an interval of 5 m were used to establish a species-area relationship. The proportion (percentage) of canopy (leaf) coverage of each species occurred within the sampling plots to the sampled soil surface area was measured. A total of 54 species belonging to 47 genera and 29 families occurred in the 25 plots develoved, with the species diversity index (value) of 2.09 using the Shannon Wiener formula. Nine species were categorized as herbaceous plants (16.67 %) while the other 45 species were categorized as seedlings (83.33 %). The average density measured was 39 individuals/m or c. 386.400 individuals/ha. The most dominant family is Euphorbiaceae (possessing 5 diffrent species) while the most dominant species is Urochloa subquadripara (Poaceae) with and importance value of 96.08%.

Abstract

A quantitative study of epiphytic plants was conducted at the logged over forest in Kiyu, Meratus Mountain, Hulu Sungai Tengah, South Kalimantan. This study used a plot of 10 m x 500 m (± 0,5 ha), and divided into 50 subplot of 10 m x 10 m. The results showed that there were nine species of six genera from three families of epiphytic plants found within the studied plot, with A grostophyllum bicuspidatum as the dominant species. The diversity index (H’) was of 1,85. The diversity of epiphytic plant in these plots was well represented based on the results of analysis of species area curve. Spatial distribution pattern of all epiphytic species was homogeneus, except for A. bicuspidatum. The number of epiphytic host plants observed was 22 individuals from six species of six genera, and five families, with Saurauia nudiflora (Acthiniaceae) was the dominant host plant.
