ANALISIS POTENSI REGENERASI POHON DI HUTAN KOTA UNIVERSITAS INDONESIA
Abstract: A study of tree
regeneration potential in urban forest of Universitas Indonesia was conducted
in Februari—April 2014. Location was established was divided into 42 quadrats
20x20 m each which used to obtain trees data, plots of 10x10 m each which used
to obtain pole data, plots of 5x5 m each which used to obtain sapling data, and
plots of 2x2 m each which used to obtain seedlingsdata. The secondary data was
processed to obtain vegetation data, and tree regeneration analysis then
conducted. We recorded 417 individuals of trees seedling, representing 36
species and 17 family. Three species which had highest density of seedlings
were Intsia bijuga Kuntze. (80),Hevea brasiliensis Muell. Arg. (56), and Ficus
hirta Vahl (46). At the sapling stage, 387individuals were recorded
representing 43 species and 22 family. Three species which had highest density
of saplings were Ficus hirta (55), Psychotria viridiflora Reinw. Ex Bl. (41),
and Grewiatomentosa Juss. (41). At the pole stage, 76 individuals were recorded
representing 29 species and 15 family. Three species which had highest density
of poles were Swietenia mahagoni (L.) Jacq. (12), Grewia tomentosa (10), and
Macaranga tanarius (L.) Mull. Arg. (7). Forest tree regeneration ability in
urban forest of Universitas Indonesia was counted into a good category. A total
of 23 species (69,7%) of 33 tree species were regenerating in plot and 9
species (27,27%) have a complete regeneration phase. Fabaceae , Euphorbiaceae,
Tiliaceae, dan Moraceae were afamily that has a good potential for regeneration
and will filling the forest in the future.
