Abstract

Bengkunat Protected Forest was the area between the Bukit Barisan Selatan National Park and society settlements. Species composition and vegetation structure were the two things that influenced the complexity’s of forest vegetation. The aims of this research were to identify the species of plants and analyze forest vegetation structure. This research was conducted in March–April 2019 at the 4,470 ha area with the sampling intensity 0.02%. Data collected by the grid line method that was consisting 34 sample plots within the distance 100 m between the plots and 200 m between the lines. The numbers of identified plants species at the research location were 92 species, classified by 34 families and 71 genus. The forest vegetation was consisting by the different growth phases. The seedling phase was the highest density of 4,058.8 species/ha, while the tree phase was lowest density of 262.5 species/ha. The highest canopy cover was the pole phase of 12,186.0 m2/ha (121,9%) and the lowest canopy cover was the seedling phase of 1,838.4 m2/ha (18,4%). The forest crown stratification were consisting of A, B, C, D and E stratum. The highest number of plants were from C strata for 436 trees and the least from A strata of 23 trees with the highest tree is 42 m. Could be concluded that the composition of Bengkunat Protected Forest have so many number of species and complex structure vegetation forest. Key words : Bengkunat Protection Forest , species composition,and vegetation structure.

Abstract

Beringin Jaya Community Forest is one of the community forests in Tanggamus Regency, Lampung Province. The economy of the forest farmers highly depends on the productivity of the forest land. One of the things can be done to improve forest productivity is by doing maintenance in the forest stand. Therefore, research regarding forest maintenance done by forest farmer is significantly important to be conducted. The aim of the research is to figure the maintenance system done by the farmers. The data is collected through direct observation and interview towards 72 respondents. The study shows that 72 farmers (100%) conduct weeds clearing and pruning, while transplanting conducted by 65 farmers (90.3%), 51 farmers (70,8%) apply fertilizer, 24 farmers (33,3%) doing tillage, 14 farmers (19,4%) do pest and disease management. Transplanting technique while they use is by planting seedlings in the hole sized 40cm x 40cm x 40cm during wet season. Tillage is done by tilling the soil around the tree with diameter 20–50 cm, mostly it is done during the dry seasons. Weeding was done conventionally and chemically, 3–4 times per year. Organic and chemical fertilizer is used by the farmers which applied in the wet seasons. Fertilizing is being done by buried the fertilizer around the plants. In the other hand, unproductive branches will be pruned, the pruning was usually done in the wet season. Pest and Disease management conducted by the farmers were by making a trap or hunt the pest down. Keywords: maintenance, community forest, forest farmers.
