All Theses
Baldcypress (Taxodium distichum, [L.] Rich.) -tupelo (Nyssa spp.) swamp forests are a major component of the total area of southeastern U.S. forested wetlands which provide valuable ecosystem services related to water quality, stormwater catchment, and wildlife habitat. Historically, baldcypress has also been an important source of wood products, and clearcutting the principal method of harvesting and regenerating the species. However, anthropogenic alterations to flows of many rivers and the associated flood patterns of alluvial wetlands have prevented the establishment of new baldcypress cohorts in many swamps. Regular, extended growing season flooding could prevent germination and/or establishment of baldcypress seedlings if …

Leaf Area Index - Relative Density Relationships In Even-Aged Abies Balsamea - Picea Rubens Stands In Maine, Robert Justin Derose
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 …
