Abstract

Penelitian ini bertujuan untuk mengidentifikasi pohon inang epifit (porofit) pada hutan bekas tebangan setelah 6 tahun pembalakan seluas 12 hektar di Hutan Penelitian Malinau (MRF-CIFOR) pada hutan dataran rendah DAS Malinau.  Pohon inang epifit di hutan bekas tebangan ditemukan 50 pohon per hektar, yang terdiri dari 162 spesies dalam 42 suku dengan 484 pohon (79.9%) berdiameter 20-51 cm.  Pohon inang dari family Dipterokarpa di temukan paling banyak di hutan bekas tebangan (± 50%). Shorea parvifolia Dyer. merupakan pohon inang paling banyak ditemukan (34 pohon).

Abstract

Throughfall is part of the rainwater that falls onto the surface of the soil through the cracks and the canopy or in the form of runoff from the leaves, twigs or branches. This study aims to determine the effect of rainfall on the stand throughfall Aubreville architecture models, Leeuwenberg and Stone. To calculate the amount of throughfall measurements directly on three models of tree architecture Aubreville, Leeuwenberg and Stone each repeated 3 times measured for 30 times the rainfall event. The results showed the highest throughfall Aubreville models by 18.74% and the smallest model of Stone 12.36% of the total rainfall 413.60 mm. Relations with throughfall precipitation is 75% in model Aubreville, 36% and 43% models Leeuwenberg Stone models.Keywords: Throughfall, stem flow, architecture model, watershed
