ACKNOWLEDGEMENTS

This report is submitted for the Advanced Education Program Developed in

collaboration with Colorado State University, USA, faculty of Forest Resources and

Emvironmental Management, Vietnam Natural University of Forestry. This study would not

have been possible without the kindness help of many individuals and institutions. Most

importantly, I am very grateful to my supervisor Dr. Ha Quang Anh for his guidance,

instruction, and encouragement at every step of my study and for sharing his knowledge and

ideas with me.

I would like to thank Hoang Lien National Park (NP), Science and International

Cooperation Department of the NP with many good people who provide documents and go to

the field survey with me.

ABSTRACT

This study contributed findings of some main characteristics of natural forest in high

zone vegetation in Hoang Lien National Park included trees floors, regenerated trees and

shrubs, fresh vegetation floors. Based on the research objectives, a study decision used

fieldwork methods and some document from the publications and files of different agencies

combined with calculate by formula of excel software and SPSS to find the result about

characteristics of vegetation above 2700m elevations. From that, the study will proposed

measures served to forest management; improve efficiency for the protected forests.
