The Technique of Agroforestry at Communal Forest Areas in Pejarakan Village, District of Gerokgak, Regency of Buleleng, Bali Province
Abstract
Since 2003, the technique of agroforestry with alley cropping systems has been implemented at the forest areas in Pejarakan Village, District Gerokgak, Regency of Buleleng, Bali Province. These activities are expected to support the progress of welfare for farmers, though they have been neglected to preserve forest around village. The result of the research shows that the result of the activities do not fulfill its first expectation. The analysis on the compositions and structures of vegetations in this research shows that the dominant type of species which was mainly cultivated had the character of Importance Value Index, while the balance of species among diversity index was still low at all of the communal forest areas and even at the slope sides. The composition and the structure of species were still few, and the vegetation itself was disturbed by people. With regard to illegal loggings, cuttings top branches or twigs often occuredr, and these activities brought about obstacle growth of trees in communal forest areas.It is concluded that the technique of agroforestry at the communal forest areas has few compositions of species and structure of vegetations, so the diversity of species becomes very poor and unstable, either for plants in forestry or for agricultural crops. The researcher could not determine what species of vegetations is superior at this area. Therefore, it necessarily needs some more time for intensive observations and research at this communal forest areas.
