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.

Opportunities for Collaboration: A study of the participation in student activities and young alumni giving

Thu, 11/29/2012 - 20:23
Abstract: Student activity programs developed in collaboration of student affairs and alumni offices increase young alumni involvement. The successfulness of student activities in cultivating young alumni donors is unknown. The purpose of this study is to determine if the giving behaviors of young alumni can be enhanced by the participation in student activities. Current “involved” students will be queried through focus groups to gather insights as to their intentions of financial giving upon graduation. Recent graduates between the years 2007-2010 will be queried as to their giving behavior towards the college as well as activity engagement during their years at Paul Smith’s college and specifically what that engagement was. Colleges will better understand the benefits of implementing student activity programs.

Soil and Vegetation Characteristics of High Elevation Wetlands in the Adirondack Park

Mon, 12/03/2012 - 17:14
Abstract: Wetland ecosystems are finally being understood for their true importance. Wetlands in the past were misunderstood and thought to be disease carrying burdens on our way of life; however this mentality changed during the mid-19thcentury. These ecosystems are important for biodiversity and act as natural water purification systems. This study was undertaken to help understand, the high elevation wetland characteristics. Our goals were to analyze the soils and describe the vegetation in high elevation wetlands. The soil and vegetative surveys helped define the characteristics of these ecosystems and create a better understanding of them. The combination of vegetation species that are wetland indicators were found in each site, the soil pH, and nutrients show that each site had signs of being a wetland community.

Distribution of Native & Non-native Ground Flora in Upstate New York in Relation to Nearby Forest Roads

Fri, 12/07/2012 - 17:26
Abstract: Plant distribution and diversity are affected by disturbances in forested landscapes. Disturbances such as forest roads including skid trails and haul roads are among those which affect plants. The introduction and spread of invasive species is a big concern with these types of roads because of the damage these species cause to the ecosystem. The goal of this study is to determine the effect these forest roads have on distribution and diversity of plants relative to the distance from the road. I wanted to find out how non-native and invasive species were distributed, as well as native protected species. Transects in two separate regions were set up perpendicular to the roads at the sites chosen, and each transect contained 16 – 1m x 1m plots in which all plants were surveyed. This study showed that distance away from forest roads does not appear to significantly affect the number of plant species, distribution of native or non-native plants, or distribution of protected species in New York. Based on the findings in this study, forest managers may not need to be overly concerned with the effects of forest roads on plant populations, but they should consider management of invasive species since Japanese barberry (Berberis thunbergii) was found well beyond the disturbed area in this study. Since it was found near the forest interior, it may be causing damage to the ecosystem.

Evaluation of Current Old Growth Classification System Applied to Northern Hardwood Forests of Western New York State

Fri, 12/07/2012 - 17:08
Abstract: A study of four old growth stands in Western New York was conducted to document the ecological complexities and characteristics of these isolated pockets of protected forests. These stands were compared to stands in a study, Selected Nova Scotia old-growth forests: Age, ecology, structure, scoring (Stewart et.al, 2003). Using techniques and sampling of Stewart et al., data included estimated age structure, species composition, basal area, density, coarse woody debris, volumes, heights, and snags. All of the stands were uneven-aged, as were the stands in the comparison study. All stands displayed low varying basal area ranges and lower stand density than those stands in Stewart et al. The comparison study had basal areas ranging from 32.5 to 55.5 m^2/ha, but the collected basal area of this study ranged from 14.5 to 29 m^2/ha. Volumes of dead wood ranged from 2 to 60 m^2/ha, which again was significantly less than dead wood volumes in Stewart et al. Most of the dead wood volume was derived from coarse woody debris, with few snags throughout the stands. Six attributes were rated on a 100 point system according to age, primal value, diameters, lengths of dead wood, canopy structure and understory structure. The scores of this study ranged from 52 to 70, which were significantly less than the scores in the comparison study. The Nova Scotia stands were dominated by softwood species and were larger in acreage. The western New York stands were dominated mostly by hardwood species and were smaller in acreage. Due to these differences, the western New York stands fell short of the Nova Scotia stands in two important criteria: ‘Primal Forest Value’ and ‘Bole Length of Snags and CWD.’ The protocols of Stewart et al. were generally adequate for evaluating the old growth characteristics. However, this study suggests that some of the criteria could be adapted to capture characteristics found in smaller, isolated pockets of hardwood dominated old growth forests.

Silviculture Prescription and Regeneration Analysis: An Investigation of the Creighton Compartment of the Paul Smith’s College Forest Management Plan

Wed, 12/05/2012 - 10:31
Abstract: Paul Smith’s College, being an environmental college, has a unique opportunity to explore the newest research to find the best methods of silviculture treatments to meet regeneration goals while sustaining forest structure. This study investigated the Creighton Compartment of the PSC forest management plan specifically examining the silviculture prescriptions and regeneration. Seedling and sapling regeneration data was compared with the management plan to determine whether regeneration goals were met. Overall, the hardwood stands were regenerating in vast amounts of undesired American beech (Fagus grandifolia) and not meeting the preferred goal of red maple (Acer rubrum), sugar maple (Acer saccharum), black cherry (Prunus serotina) and yellow birch (Betula alleghaniensis). The softwood stands were regenerating in vast amounts of undesired balsam fir (Abies balsamea) and not meeting the preferred goal of eastern white pine (Pinus strobus) and red spruce (Picea rubens). Based on extensive research, it has been determined that a variable sized group selection harvest was the best solution to regenerate the preferred hardwoods and a two-cut shelterwood system with at least 40 percent light scarification should be conducted to favor regeneration of preferred softwoods.

A stewardship plan for the Temple, New Hampshire Town Forest property based on multiple-use values derived from focus group research

Tue, 12/04/2012 - 12:37
Abstract: Open space and un-fragmented land constitutes a valuable community asset. In the town of Temple, New Hampshire, residents enjoy a sense of community and a rich agricultural history. Outdoor recreation is a popular activity for many residents. A hidden gem, the Temple Town Forest property, is open to the public for recreational foot traffic use, but it is not being actively utilized. The property is managed by the Temple Conservation Commission. To aid the Commission, a stewardship plan was created from focus group research with three overarching goals of forest health, increased recreational opportunities and ways the public can participate in forest management. The end result is the promotion of a managed working forest the public can appreciate. The plan provides a forest health inventory, examines recreational usage and a timber cruise identified potential trees that could be harvested. Suggestions were stated on how the public can assist in management for the Town Forest like, forming a specialized town forest committee and supporting local maple sugaring.

Influence of Stand Density and Species Proportion on the Productivity of Planted Forests

Mon, 12/03/2012 - 13:24
Abstract: This study examines the influence of stand density and species proportion in mixed species forest plantations through the Forest Vegetation Simulator (FVS), forest growth modeling software. It is hypothesized that a mixed-species stand will be more productive than any monoculture of the same density due to some compatibility between the two chosen species. Trees were “planted” in 5 different densities; 460, 540, 660, 860, and 1100 trees per acre. The ratios of eastern white pine (Pinus strobus) and eastern hemlock (Tsuga canadensis) were then altered using substitutive plot designs and grown for 100 years. The most productive stand was established as a mixed-species plantation with a white pine:eastern hemlock ratio of 60:40. This stand was established with 1100 trees per acre; 660 white pine and 440 eastern hemlock. This translates to 39.6 square feet per tree, or a grid size of about 6.29’x6.29’. This stand, after 100 years of simulated growth, was 1.0038 times more productive than highest producing monoculture of the same density. Although the hypothesis was accepted, the most productive mixed-species stand developed into a white pine monoculture after 100 years of simulation.
