  • Small Scale Teak Plantations in Luang Prabang Province, Lao
    Small scale teak plantations in Luang Prabang province, Lao PDR - Silviculture, ownership and market ii Foreword This minor field study (MFS) was carried out as part of the requirements and corresponds to 10 credits on C level. The Department of Silviculture at the Swedish University of Agriculture Sciences has planned the study in co-operation with the National Agriculture and Forestry Research Institute (NAFRI) in Lao PDR with the objective to describe the silviculture practise in teak plantations established by small-scale farmers. Besides bio- physical aspects, tenure and market prospects both for plantations as well as for the wood have been discussed. Acknowledgement This study was funded by Sida (Swedish International Development Agency) as an MFS (Minor Field study). The MFS was hosted by the Lao-Swedish Upland Agriculture and Forestry Research Programme (LSUAFRP) which is a programme financed by Sida and run by the National Agriculture and Forestry Research Institute of Lao PDR (NAFRI) and Scandia consult Natura (SCC). The MFS took in place in Lao PDR in August and September 2003 and was written in Sweden later that year. We, Niklas Fogdestam and Helena Gålnander, would like to thank the following persons for their support and assistance during the time we have been working with this project: Mr Houmchitsavath, our guide and interpreter during the field days in Pone Xay district. Mr Olle Forshed, our mentor in professional as well as social life in Lao PDR. Mr Robert Nygård, our manager and supporter in Sweden who encouraged us to study our data more thoroughly than we thought possible.

SIMMONS, logging specialist NORTHEASTERN FOREST EXPERIMENT STATION FOREST SERVICE UNITED STATES GOVERNMENT PRINTING OFFICE - - - WASHINGTON, D. C, 1951 For sale by the Superintendent of Documents, Washington, D. C. Price 75 cents Preface THOSE who want to be successful in any line of work or business must learn the tricks of the trade one way or another. For most occupations there is a wealth of published information that explains how the job can best be done without taking too many knocks in the hard school of experience. For logging, however, there has been no ade- quate source of information that could be understood and used by the man who actually does the work in the woods. This NORTHEASTERN LOGGERS' HANDBOOK brings to- gether what the young or inexperienced woodsman needs to know about the care and use of logging tools and about the best of the old and new devices and techniques for logging under the conditions existing in the northeastern part of the United States. Emphasis has been given to the matter of workers' safety because the accident rate in logging is much higher than it should be. Sections of the handbook have previously been circulated in a pre- liminary edition. Scores of suggestions have been made to the author by logging operators, equipment manufacturers, and professional forest- ers.
