Bonding Performance Of The Ten Species In The Spruce-Pine-Fir (South) Lumber Grouping For Cross-Laminated Timber, Advanced Structures & Composites Center, University Of Maine, Jake Snow, Benjamin Herzog, Russell Edgar

General University of Maine Publications

Cross-laminated timber (CLT) is an engineered wood product made of three or more orthogonally bonded layers of lumber that are glued together with structural adhesives to form a panel intended for roofs, floors, or walls.

Currently, there are no CLT manufacturers in the Northeastern U.S. despite the region having vast forestlands of commercial softwood timber. Sitting atop one of the planet’s largest population centers, Maine is the region’s primary wood basket, the most heavily forested state in the nation (as a percentage of land area) containing over 27 billion cubic feet of wood, i.e., live trees, on its forest land …

S4e2: What’S Your Relationship With The Forest?, Ron Lisnet, Jessica Leahy

The Maine Question

Maine is the most forested state in the country, and its residents interact with forests regularly in many different ways. They provide supplies for various products, which fuels industry and job creation, and space for outdoor recreation. These interactions, which help define Maine’s identity, are the subject of Jessica Leahy’s research. As a professor in UMaine’s School of Forest Resources, she studies the human dimensions of forestry and other natural resources. In this episode of “The Maine Question,” Leahy discusses her work, the ways forests impact our lives and how our actions affect them.

Tapping The Sweet Spot: Predicting The Suitability Of A Woodlot’S Potential To Transition Into A Productive Sugarbush In Maine, Deven M. Teisl

Non-Thesis Student Work

Through conversations with Dr. Sara Velardi, a postdoctoral research associate who has been doing research on maple producers’ scale management decisions in Maine, most current owners and operators in the maple syrup industry have the common interest of expanding their current operations, but they are unsure of how to approach that problem. Due to these current issues, my research focused on creating a sugarbush assessment tool. This assessment tool consists of a set of guidelines which can be utilized by current or future producers and can be used to easily assess woodlots without having to hire a consulting forester to …

Ash Decline: An Opportunity For Young Forest Wildlife, Bianca Beland

Honors College

The overall decline of ash tree health presents an opportunity for landowners to salvage dying trees, thus contributing to state and federal efforts to create young forest habitat for a wide variety of wildlife species, in addition to benefitting from the financial and recreational opportunities that come following salvage operations. This case study examines the results of a decision made by the Metropolitan District Commission (MDC, Hartford, CT) to conduct a timber salvage operation on its public water supply watershed land to remove dying white ash (Fraxinus americana) trees and at the same time meet the goals of the …

Linking Remote Sensing And Various Site Factors For Predicting The Spatial Distribution Of Eastern Hemlock Occurrence And Relative Basal Area In Maine, Usa, Kathleen Dunckel, Aaron Weiskittel, Greg Fiske, Steven A. Sader, Erika Latty, Amy Arnett

Publications

Introduced invasive pests are perhaps the most important and persistent catalyst for changes in forest composition. Infestation and outbreak of the hemlock woolly adelgid (Adelges tsugae; HWA) along the eastern coast of the USA, has led to widespread loss of hemlock (Tsuga canadensis (L.) Carr.), and a shift in tree species composition toward hardwood stands. Developing an understanding of the geographic distribution of individual species can inform conservation practices that seek to maintain functional capabilities of ecosystems. Modeling is necessary for understanding changes in forest composition, and subsequent changes in biodiversity, and one that can be implemented at the species …

Agent-Based Modeling Of Harvest Decisions By Small Scale Forest Landowners In Maine, Usa, Jessica Leahy, Erika Reeves, Kathleen Bell, Crista L. Straub, Jeremy Wilson

Publications

Small-scale forests are an excellent example of coupled social-ecological systems, which involve human and biophysical subsystems with complex two-way feedback interactions. The multifaceted nature of landowner decisions drives a significant need to better understand decision-making processes, reactions to policy, and combined impacts on ecosystems in a comprehensive manner. Small-scale forests require an integrated approach to modeling the social and biophysical components comprehensively. Agent-based modeling involves modeling individualistic behavior and interpreting patterns that emerge. The interaction between agents and their environments makes this a valuable tool to assess repeated decisions of individual landowners responding to changing environmental conditions. Agent-based models can …

Clearcutting Has A Long-Lasting Effect On Habitat Connectivity For A Forest Amphibian By Decreasing Permeability To Juvenile Movements, Viorel Popescu, Malcolm L. Hunter Jr.

Publications

Conservation of forest amphibians is dependent on finding the right balance between management for timber production and meeting species' habitat requirements. For many pond-breeding amphibians, successful dispersal of the juvenile stage is essential for long-term population persistence. We investigated the influence of timber-harvesting practices on the movements of juvenile wood frogs (Lithobates sylvaticus). We used a chronosequence of stands produced by clear-cutting to evaluate how stand age affects habitat permeability to movements. We conducted experimental releases of juveniles in 2008 (n = 350) and 2009 (n = 528) in unidirectional runways in four treatments: mature forest, recent clearcut, …

Comparing Relative Abundance Of Amphibians In Forest Canopy Gaps Of Natural Origin Vs. Timber Harvest Origin, Carol J. Strojny, Malcolm L. Hunter Jr.

Publications

Relative abundance of amphibians in forest canopy gaps of natural origin vs. timber harvest origin.— Small–scale canopy gaps created by logging may retain adequate habitat structure to maintain amphibian abundance. We used pitfalls with drift fences to measure relative abundance of amphibians in 44 harvested gaps, 19 natural treefall gaps, and 36 closed–canopy forest plots. Metamorphs had relatively lower capture rates in large harvest gaps for Ambystoma maculatum, Lithobates catesbeianus, L. clamitans, and L. sylvaticus but we did not detect statistically significant (p < 0.1) differences among gap types for Lithobates palustris metamorphs. L. clamitans juveniles and L. sylvaticus juveniles and adults had relatively …

Farms To Forests In Blue Hill Bay: Long Island, Maine, Kristen Hoffman

Maine History

Disturbance histories are important factors in determining the composition and structure of today’s forests, and not least among these disturbances is the human use of the land. Land clearing in Maine peaked in 1880 at six and a half million acres, beginning on the coast and lower river valleys and spreading northward and eastward. The forests of Maine’s coastal islands have endured a longer period of clearing than any other in the state. Long Island, located in Blue Hill Bay, was first settled in 1779, primarily by farmers. Sheep-herding, lumbering, fishing, and granite quarrying provided supplemental livelihoods. By 1920 all …

Mp716: New Forestry In Eastern Spruce-Fir Forests: Principles And Applications To Maine, Robert S. Seymour, Malcolm L. Hunter Jr.

Miscellaneous Publications

Eastern North America's spruce-fir forests have a unique ecological and human history which is reflected in their current vegetation, ownership patterns, and forest management practices. Furthermore, there are important differences within the region between the true boreal forest and the sub-boreal Acadian forest; this paper emphasizes the Acadian forest. Applying New Forestry to this region will require a modified approach which we outline by describing three basic principles. First, to provide the landscape context for New Forestry, we propose a triad of forest land allocation in which reserves and plantations would co-exist, surrounded by and embedded within a landscape managed …

Tb15: The Standardization Of Symbols In Forest Mensuration, International Union Of Forestry Research Organizations

Technical Bulletins

This technical bulletin reprints the recommendations on the standardization of symbols in forest mensuration, originally published in 1959. The recommendations were made by a small working group in Section 25 of the International Union of Forestry Research Organizations, which was appointed at the Congress of the Union held in Rome in 1953. Members of the group were asked to enquire into the possibility of standarizing the use of symbols (and the systems of measurement) in forest mensuration and to make recommendations.
