KELIMPAHAN JENIS DAN ESTIMASI PRODUKTIVITAS FICUS SPP. SEBAGAI SUMBER PAKAN ALAMI ORANGUTAN SUMATERA (PONGO ABELII) DI PUSAT PENGAMATAN ORANGUTAN SUMATERA (PPOS), TAMAN NASIONAL GUNUNG LEUSER
ABSTRACT: Ficus spp. a feed
source tree that is a keystone species for primates and birds. Availability
Ficus spp feed. This needs to be evaluated. Therefore, the availability of this
feed is quantified through Ficus spp abundance. and estimates of productivity
growth in young leaves, fruits, and flowers Ficus spp. The methodology used in
this research is the analysis of vegetation and Zweifel method. The results
were obtained Ficus spp abundance. highest in saplings found in trail 1
(4.325). Ficus spp abundance. relatively rare. Estimated productivity of young
leaves in the January to April period of observation ranges from 30% -40%.
Estimated productivity of flowers in the period January to April tends to
moderate. Estimated productivity of fruit in the January to April period of
observation ranged from 1-100 pieces per month. Period fertilization occurs
after the flowering period, so the number of pieces that appear influenced by
the growing amount of interest. If the amount of interest a little, then the
amount of fruit too little. Observation period of January to April, including not
tend to dry the fruit season. Other species in ecological niches are black
squirrels and hornbills. Keywords: Ficus spp., Zweifel, estimated productivity,
species abundance, ecological niches.
