The influence of a common parent on sap sweetness among open pollinated sugar maple (Acer saccharum Marsh.) offspring

Wed, 05/08/2019 - 15:08
Abstract: Beginning in the 1950s, the United States Forest Service began to look into the ability to predict and control the heritability of sap sweetness in sugar maples (Acer saccharum Marsh.). A search for genetically superior (sweeter) trees was conducted across 6 states, testing 21,000 trees. Only 53 trees were chosen to be parental stock for the “Super Sweet” sugar maple improvement program. These trees, cloned through rooted cuttings and scion wood grafting, were planted in the Grand Isle, VT clonal bank. One of the five progeny tests of open pollinated offspring from the clonal bank was established in Lake Placid, New York. These trees had their first evaluation at age ten. Each tree had its diameter and height measured, as well as its sap sweetness tested. Now, 35 years after planting, the trees were evaluated again. An inventory was conducted with diameter at breast height, tree height, and live crown ratio measurements. Of the 725 trees planted, only 396 trees remain. Only 258 trees were of size and quality to handle a 5/16” tap. Their sap sweetness was measured at multiple times though out the season. Knowing one of the two parents of each tree allowed for the comparison of the sap sweetness of the different common-parent groups. The data collected did not support that the knowledge of only one parent could be used to predicts a tree’s sweetness relative to any other parent’s offspring. The bigger picture progeny evaluations will continue the “Super Sweet” sugar maple improvement program.

Reinvigoration of the Champlain-Adirondack Biosphere Reserve: Stakeholder Perceptions

Tue, 05/08/2018 - 15:02
Abstract: The Champlain-Adirondack Biosphere Reserve (CABR) was designated by the United Nations in 1989. This reserve spans the entire Adirondack Park, and includes the Lake Champlain Valley in Vermont as well. Biosphere reserves focus on conservation at a global level, and use international knowledge from lessons learned to best benefit each specific biosphere. Although CABR was designated in 1989, it became classified as inactive soon after. In 2016, Brian Houseal, Director of SUNY's College of Environmental Science and Forestry Newcomb Campus, prepared a periodic report to UNESCO on CABRs current status. The goal of this research was to determine the probability of stakeholder support to bring CABR out of inactivity, almost 20 years after it was designated originally. The research performed focused on stakeholders’ awareness and perceptions of the CABR, along with past indications of concerns and resistance among local residents. The research addresses this deficit and identifies and clarifies our representative’s samples perceptions of the designation. The research revealed that land use rights were still the major concern. The research revealed that this was still a concern because there is still a major lack of information on the CABR land classifications/land use rights. Information on CABR was concluded to be one of the largest challenges at this time. This research revealed that 68% of the residents were unaware of CABR until the periodic review was published in 2016, and over 40% of the residents had no idea what CABR was until they received an invite to come to the focus group.

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.

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.

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.

Comparison of 5 Firewood Storage Structures for Most Efficient Drying of Acer rubrum in Northern NY

Thu, 05/10/2018 - 12:47
Abstract: Worldwide over 2 billion people use firewood to heat their homes. The cultural relevance of the act of stacking firewood means that there are many different recommended methods of stacking and storage. For this study we tested five structures for the drying of firewood, and measured change in moisture content over five weeks to determine which method was the most efficient. Red maple (Acer rubrum L.) and Black cherry (Prunus serotine L.) trees were felled in the Creighton Hill Tract and hauled 1.2 miles to the study site behind the Paul Smith’s College John Dillon Sawmill in Paul Smiths, New York. There they were split and stacked into the five different methods, which included a heap, uncovered stack, covered stack, shed, and stack wrapped in plastic. Moisture content readings were taken from nine red maple pieces within each stack three times a week for a total of five weeks. Uncovered firewood was most susceptible to changes in moisture content in response to precipitation. Covered stacks of wood had the greatest decrease in moisture content over the course of the study, and also proved to be less vulnerable to precipitation events. Firewood wrapped in plastic maintained significantly higher moisture content than the other methods consistently throughout the study.

PROPOSED DAY-USE SITE AT THE ADIRONDACK LAND TRUST GLENVIEW PRESERVE

Fri, 12/14/2018 - 15:43
Abstract: Glenview Preserve is a lowland mix deciduous forest that boarders the Bloomingdale Bog. The property would be a quintessential location for public engagement through a day-use site, which in turn would ensure future use and elevation of the Adirondack Land Trust and their mission objectives. Through the determined design goals and the predetermined ALT goals for the property a comprehensive blueprint has been presented. The proposed day-use site is predicted to increase the three essential services that communities in the Adirondacks thrive off of. Their economic value, health and environmental benefits, and their social importance streamlines with the ALT’s management practices and goals to provide a beneficial educational and recreational space for the community.

Does the presence of Malus spp. increase the fertility of the soil surface in pastures?

Mon, 05/01/2017 - 18:24
Abstract: Techniques to increase soil fertility in a pasture can benefit the system by combating soil degradation and increasing the health of vegetation. The use of apple trees (Malus spp.) may be particularly beneficial in achieving this due to reliable fruit yields, ease of management, and variety of suitable habitat. We hypothesized that soil directly under the canopy of apple trees would be higher in nutrients (C, Ca, K, Mg, N, & P) than soil in areas with no tree cover. Soil samples were taken from the top 15 cm of the soil surface under apple trees and in areas without trees at 14 sites in Massachusetts and New York. Samples were analyzed using spectrometry and color imagery to determine nutrient content. Potassium and magnesium concentrations were found to be significantly higher in under-canopy samples. Further research may expand these results and determine if the application of apple trees can be used to increase the health of pasture systems.

Creating a Reliable Surveying Network: Does Adding New Survey Control Points to Paul Smith’s College Campus Enhance its Current Network?

Tue, 12/05/2017 - 18:48
Abstract: The goal of the project was to improve the current geometry of the Paul Smith’s College surveying network. Four new survey control points were added to the current network allowing for new connectivity to old control points. Previously, there was a Westside network and an Eastside network that were not connected and by connecting these two networks, it has expanded the current network further into the campus. Two different methods were used to help identify the new network. A traditional survey method, a closed traverse, was used to connect the old control points to the new control points by utilizing a Nikon DTM-352 series total station. A X90 OPUS GPS unit was used to connect the new control points into a geodetic network. After the data was collected a least squares adjustment was done to the closed traverse to correct for error within the traverse. The GPS data was processed by Topcon Tools utilizing a Continuously Operating Reference System (CORS) to obtain a better level of accuracy for the network it produced. The two different techniques used produced different results in the overall survey networks and supplied different coordinates than what has been previously used by students at the college. These results gained from the project are not of a consistent level of precision and are not recommended for use without conducting more closed traverses to increase precision within the network.
