Electronic Theses and Dissertations
Relationships between leaf area index (LAI) and relative density (RD) were examined in even-aged stands of Abies balsunzen (L.) Mill. and Piceu rubens Sarg. Twelve sites distributed across the Acadian forest in Maine were used to test conformance to three hypothesized models of LA1 over RD: A) constantly increasing LA1 over increasing RD, B) constant LA1 with increasing RD, or C) decreasing LA1 with increasing RD. Multivariate ordination suggested young, precommercially thinned (PCT), high-siteindex (SI) A. balsamea stands should be analyzed separate from older, unspaced (NOPCT), lower-site P. rubens stands. All-sided A. balsamea LAIs ranged from 6.2 - 14.8 over …
