1 Draft Field Guide Insert for Site Identification of Seral Populus Units of the Northeast Portion of the Prince George Forest Region April 2002 Ministry of Forests

2 2 Draft Field Guide Insert

3 PREFACE This draft field guide insert is intended to provide operational personnel with an interim tool for site unit identification for areas of the Prince George Forest Region where there is no recently published guide available. The guide is intended to replace Land Management Handb andbook ok #16 A Field Guid uide e for r Ident ntificat ificatio ion and Interpretation of Seral Aspen Ecosystems of the BWBSc1 Prince Georg rge e Forest Regio ion. In order to use this draft guide insert effectively the user should be completely familiar with the methods of site identification using the Biogeoclimatic Ecosystem Classification (BEC) system. This insert should be used in conjunction with any of the introduction sections included with LMH # 21, 22, 24 or 29. Due to the interim nature of this guide the opportunity exists to incorporate constructive comments from the users. PLEASE PROVIDE ANY COMMENTS S RELATING TO ERRORS OR SUGGESTED IMPROVEMENTS TO THIS GUIDE TO CRAIG DELONG AT T THE PRINCE GEORGE GE REGIONAL AL MINISTRY Y OF FORESTS S OFFICE. SPACE CE HAS BEEN PROVIDED ON THE REVERSE SIDE OF THIS PAGE GE TO WRITE DOWN COMMENTS ABOUT THE GUIDE WHILE IN USE IN THE FIELD. Draft Field Guide Insert 3
