Abstract

The existence of herbaceous was importance in order to the ability in soil and water conservation. A survey of soil infiltration rate at various land that dominated by herbaceous plants was conducted at Matang Wildlife Centre, Sarawak, East Malaysia. The highest infiltration rate (2.45 cm/minute) was observed at herb land which dominated by Mikania micrantha Kunth. The land that dominated by Fimbristylis glubolosa Vahl showed the lowest infiltration rate (0,06 cm/minute). According to growth types, the vegetation of herbaceous that categorized as boadleaf reached the highest infiltration rate (2.00 cm/minute), followed by fern (0.68 cm/minute) and grass (0.59 cm/minute). The infiltration rate of mixed dipterocarps forest which is situated near the study site was 2.56 cm/minute. Information about the infiltration rate of herbaceous plants is useful for soil and water conservation, biodiversity, and forest management and conservation.Keywords: Infiltration rate, herbaceous, cover crops, and Sarawak.

Abstract

Ironwood or Ulin (Eusideroxylon zwageri Teijsm. & Binn.) coppice are potential natural regeneration to preserve Ulin resouces. A survey of ironwood regeneration was conducted as long as Belian Trail in Kubah National Park, Sarawak, Malaysia. A total of 33 coppice-shoots were recorded on 22 Ulin stumps. There were 6 seedlings, 49 saplings, 23 poles, and one tree recorded surrounding the coppicing. They were found in Quadrant I (25), Quadrant II (27), Quadrant III (16), and Quadrant IV (9). Information about regeneration and coppicing pattern of Ulin are useful for forest management and conservation, due to availability of their high natural regeneration.Keywords: Distribution, regeneration, coppice, stump, ironwood.
