Vista Wellness: An Educational Community Center for the Glenview Preserve
Fri, 12/14/2018 - 23:29
Abstract: The Glenview Preserve is home to a beautiful open vista of the High Peaks. This land was recently purchased by the Adirondack Land Trust and is looking for ways to sustainably manage the property by utilizing Paul Smith’s College capstone students for recommendations. One viable opportunity the ALT can incorporate, is the addition of a sustainable forum and conference center. With a community-oriented mind, Vista Wellness will provide a multitude of spaces for businesses and individuals to retreat while partaking in recreational activities. Vista Wellness is designed to be low impact with features such as a living roof and LEED certification. Using a promotional commercial and an intricate model, using state of the art construction supplies, we are able to convey the need for this addition to the Glenview property.

Antifungal activity of propolis, neem oil, and cedarwood oil against the white-rot fungus Trametes versicolor on American beech
Fri, 12/07/2018 - 16:27
Abstract: Fungi are often considered the most destructive organisms to attack wood that has gone through the milling process, so developing compounds to resist decay are extremely important. Copper chromated arsenic (CCA) was an industry standard until 2003 when its use was restricted due to environmental concerns. Thus, research into environmentally friendly compounds has become more common. This study investigated which compound, propolis extract, neem oil, or cedarwood oil, would best preserve beech wood exposed to Trametes versicolor. Extracts for each of the compounds were prepared using denatured ethanol, and infused into wood blocks using a vacuum pump. Blocks were made of American beech (Fagus grandifolia Ehrh.) and were 10mm x 20mm x 5mm in size. The blocks were subjected to a common white-rot fungal strain, Trametes (= Coriolus) versicolor (L.) Lloyd (1920), for six weeks. Overall, propolis and cedarwood oil treated blocks lost significantly less mass than both neem and control blocks, suggesting they have potential for use as natural wood preservatives, and could be used as cobiocides.

Coarse Woody Debris Volume Following Conventional and Whole-Tree Harvesting
Tue, 12/04/2018 - 16:50
Abstract: Coarse woody debris (CWD) affects important ecological patterns and processes in the forest, including nutrient cycling, carbon stocks, wildlife habitat, regeneration dynamics, and hydrology. Timber harvesting practices have been shown to affect the abundance and distribution of CWD in forest stands. This study separates timber harvesting practices into two categories: conventional harvesting (CH), where only the main stem of trees and possibly some large branches are harvested, leaving branches, twigs, leaves, buds, and other plant parts to decompose on the forest floor, and whole-tree harvesting (WTH), which removes the entire aboveground portion of trees. I measured post-harvest CWD volume within recent patch clear cuts in Vermont, comparing results between CH and WTH. Conventional harvesting sites contained significantly more (p = 0.04) CWD volume (954ft^3/ac) than WTH sites (422 ft^3/ac). In other words, CH resulted in a post-harvest CWD volume 126% greater than the volume resulting from WTH. The most important difference was a wide discrepancy between treatments in decay class 2, which contained 66% of the total CWD volume. The increased reduction of CWD through WTH, especially when carried out over multiple rotations, may have negative effects on future site productivity, as well as richness and abundance of wildlife. The choice to employ CH or WTH may also affect the carbon balance, regeneration dynamics, and hydrology of forest stands.

ECTOMYCORRHIZA’S INFLUENCE ON SEEDLING GROWTH
Tue, 12/04/2018 - 14:16
Abstract: Mycorrhizae play an important role in forest ecosystems through their symbiotic relationship with trees and root systems. Of the mycorrhizae, ectomycorrhiza (EM), specifically targets softwood species and some hardwoods. In this experiment, the results of a powdered EM inoculum and red oak (Quercus rubra L.), pitch pine (Pinus rigida Mill.), and red spruce (Picea rubens Sarg.) were evaluated during one growing season. The study compared a control of no EM and treatment with EM in seed grown trees in containers. Difference between heights of the treatment and control were recorded to see if the inoculum impacted seedling growth of the host species. Throughout this capstone the hypothesis states: An ectomycorrhizae (EM) powdered inoculum would influence pitch pine, red spruce, and red oak seedlings height and biomass for the duration of one growing season (April-Late August). Red oak control exceeded treatment in biomass but not height, and pitch pine and red spruce treatment exceeded control in height and biomass.

Forest Structure and Composition in the Smitty Creek Watershed
Wed, 12/14/2016 - 09:56
Abstract: The 2016 Smitty Creek CFI (Continuous Forest Inventory) study addressed the issue of creating a reliable and repeatable inventory design to examine general forestry trends and their relationships with the watershed itself. Identifying these trends and their consequences is important when considering factors linked to climate change, such as carbon storage and allocation. The objective of this project were as follows: establish 10 new CFI plots, monitor and record for signs of disease and insects, tree mortality, and overstory wildlife habitat, accurately estimate forest carbon sequestration, record understory composition in a 1/50th acre area around each plot center, and suggest methods and reasons for application in Paul Smith’s College CFI capstone projects. The study was conducted within the Smitty Creek watershed in Paul Smiths, NY with the plots falling on a transect that runs north and south. At each plot, trees within the radius were assigned numbered aluminum tags, trees were measured at diameter at breast height, and other features, such as snags, were recorded. Upon completing the project, 10 CFI plots had been created and their locations were recorded, several diseases and forest health concerns were identified, as well as, tree mortality and wildlife habitat considerations, carbon sequestration for the watershed was modeled over the next century, and a CFI project was designed for the Paul Smith’s College land compartments. The Smitty Creek watershed CFI project is repeatable and has an accurate baseline of information for future studies, and the Paul Smith’s College land compartments CFI plot design is ready for implementation.
