Creator:: Morrell, Jeffrey J.
Abstract:: The specification, inspection, and remedial treatment of utility poles are addressed. Included are discussions of enhancing specifications for improved performance, techniques for detecting decay and other defects, and chemical treatments available for arresting decay of poles in service.
Resource Type:: Technical Report

Creator:: Silva, Antonio, Gartner, Barbara L., and Morrell, Jeffrey J.
Abstract:: While wood plastic composites have gained an increasingly large share of the market for decks and other outdoor structures, there are many questions about the long-term potential for biodeterioration of these materials. While the plastic does appear to retard moisture uptake, thereby slowing the rate of degradation, a number of...

Creator:: Taylor, Adam M., Gartner, Barbara L., and Morrell, Jeffrey J.
Abstract:: This paper reviews literature on the formation of heartwood and on the components that affect natural durability. It includes discussion about the function of heartwood in living trees, factors influencing the natural durability of heartwood, the process of heartwood formation, and variations in heartwood quantity and quality. Heartwood formation is...

Creator:: Domec, Jean-Christophe, Warren, Jeffrey M., Meinzer, Frederick C., and Lachenbruch, Barbara
Abstract:: The cohesion-tension theory of water transport states that hydrogen bonds hold water molecules together and that they are pulled through the xylem under tension. This tension could cause transport failure in at least two ways: collapse of the conduit walls (implosion), or rupture of the water column through air-seeding. The...

Creator:: Morrell, Jeffrey J., Paillard, Alice, Gnoblei, Dominique, Gartner, Barbara L., Milota, Michael R., and Rhatigan, Ronald G.
Abstract:: The air permeability of western hemlock from coastal forests in western Oregon was assessed. Permeability varied widely among trees, as well as by position within individual trees. Permeability tended to decrease with distance inward from the bark, a trend implying that this species produces a heartwood zone. These variations may...

Abstract:: This study investigated the mechanisms involved in the regulation of stomatal closure in Douglas-fir and evaluated the potential impact of compensatory adjustments in response to increasing tree height upon these mechanisms. In the laboratory, we measured leaf hydraulic conductance (Kleaf) as leaf water potential (Yl) declined for comparison with in...
