Studi Pendahuluan Struktur Vegetasi Hutan Gambut di Pulau Padang, Propinsi Riau

Abstract

Pulai Padang forest vegetation is a typical peatswamp forest on ombrogenous peat, that is the most common pest in eastern coast of Sumatera. The peat is characterized by very acid drainage water and poorness in nutrients (oligotropic). The surface of the peatswamp is almost beyond the reech of flood-water and tiles, except for a thin layer of mangrove forest around the coast. There are no nutrienst entering the system from the mineral soil below the peat, and the only nutrients input comes from the nutrients-poor rain. Because of this condition, there is a decrease toward the centre of the peat areas in the ammounts of mineral nutrients in the soil.
