Stand and Site Conditions Associated with the Abundance and Distribution of Black Spruce and Balsam Fir Advance Growth in Northeastern Ontario

Résumé du livre

Protection of advance growth by careful harvesting methods is attractive for a number of reasons, and offers the potential for lower-cost regeneration of suitable stands. This paper describes a study conducted to evaluate stand and site conditions associated with the abundance and distribution of advance growth at 85 stands located throughout north-eastern Ontario. Data from surveys using replicated, fixed-area plots were combined with information collected during previous research on 320 additional stands. Site and stand factors associated with black spruce and balsam fir advance growth, and relationships of advance growth abundance to forest ecosystem classification (FEC) types, were explored using multiple regression and other analytical techniques. The paper discusses stand and site factors associated with advance growth in relation to forest inventory, FEC information, and to aerial photographs. Keys are provided to assist in recognizing stands with the capability to support abundant black spruce advance growth.
