213 Management of natural resources in tropical peat swamp forest of Indonesia Ujang Suwarna 1, 1 Department of Forest Management, Faculty of Forestry, Bogor Agricultural University, 16680, Indonesia Corresponding author: usuwarnyahoo.com Abstract Tropical peat swamp forest in Indonesia has important functions that consisted all aspects of hydrology, ecology, economic, and social. Meanwhile, timber harvesting activities could potentially reduce some functions of the tropical peat swamp forest. Measurement and calculation of natural resources in the tropical peat swamp forest should be done accurately to evaluate implementation of timber harvesting activities in the tropical peat swamp forest and also to estimate biomass and carbon stock. The objective of the study was to know changes of natural resources in order to evaluate implementation of timber harvesting activities in the tropical peat swamp forest. The study was conducted in the forest concession area of PT. Diamond Raya Timber, Riau Province, Indonesia. The study found out that timber harvesting activities in the tropical peat swamp forest has reduced about 29 of standing trees and also decrease 23 of forest biomass and forest carbon stock. It indicated that implementation of timber harvesting activities in the tropical peat swamp forest should be improved through best forest management and advanced timber harvesting techniques.

1. Introduction

Tropical forest was important agent in global climate change mitigation through absorption and storage of carbon in form of biomass. One of forest ecosystem type that has potential to absorb and store carbon was tropical peat swamp forest. Tropical peat swamp forest should be managed through best forest management practices because it has very important functions that consisted all aspects of hydrology, ecology, economic, and social. Based on data in 2006, Indonesia had 21 million ha of tropical peat land that consisted 9 million ha 43 of non forest area and 12 million ha 57 of tropical peat forest area [1]. The tropical peat forest area was used as conservation function 28 and production function 72. Timber
