Bogor, 21-22 October 2015 624 mentioned that the plant growth means increasing volume of height or diameter on plant stem. Table 3: Analysis of variance of the diameter growth of four local species on agroforestry system in Nagrak, Sukabumi District, West Java Sites Species N Mean

Parameter of chlorophyll content was very important to be measured, it was for analyze of anorganic material to be organic material in plant leaf Tjitrosoepomo, G. 2007. This process photosynthetic of course needs chlorophyll content and sunlight. Eventough, all species shows has no significant different but species A. excelsa shows the second number of chlorophyll content in forest plantation 5.97 and the greatest number in homegarden plantation 2.62.

It means that four local species on this study has good prospect for tree establishment program. Because tree establishment can maintain and rehabilitate degraded rural land, even in Australia, strategically placed trees can help control salinity, reduce erosion and provide shelter for livestock Dunn et al. 1997. 1.3 Habitat of Local Insect Plantation using local plant species was assumed be able to attract local insect species. There were insect species be found in the agroforestry system plantation in utilization zone forest and home-garden. Insect found in this study was dominated by species Anapholepis gracilipes, this species lives as predator Ito et al. 2001. This species was found in the surface of forest soil and it lives on forest litter and plant root area. A. gracilipes is attacking many pest in agroforestry system plantation. This species is similar with Coccinela sp. that has habitat on plant species E. Bogor, 21-22 October 2015 625 angustifolius. Insect species Coccinela sp. is also live as predator in plant leaves and it is purposes to attack leaves pest Karmawati et al. 1999. In contrary for Apis mellifera that has habitat in M. champaca and lives as pollinator. This species can pollinate many flower of plant in agroforestry system Freitas Paxton, 1998.
