Keragaman Jenis Pohon dan Peresapan Air di Lahan Terbiarkan Setelah Kebun Tradisional

Ecological aspects of abandoned lands can be determine from many aspects, including the family diversity and ability to absorb water. This study aims important value index based on tree water (infiltration rate permeability) land after traditional gardens. The vegetation survey trees with a diameter at breast height (DBH) >5 cm was carried out 10 sub-plots each measuring 20 m × m. Infiltration permeability measurements were 3 times repetitions each. highest significance values (FIV) Euphorbiaceae (104.07), Moraceae (84.75), Sapindaceae (20.94). infiltration rates 12.8 cm/hour in secondary forest (gentle slope), 6.0 (a rather steep 1.6 open 1.2 slightly slope). Permeability steep) 15.45 cm/hour, 11.15 9.82 8.93 respectively. Information about absorption used as basis for consideration managing future.
