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.

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.

The effects of different users on tree height measurements in two mixed hardwood stands in northern New York: A comparison of three measuring instruments.

Tue, 05/08/2018 - 20:23
Abstract: Height measurement in the forestry industry is one of the most important measurements that is needed for forest inventories but also one the most difficult to accurately obtain. There are many different types of tools that industry professionals use to measure tree heights. Those tools that are used vary greatly in price and quality which is considered by companies when deciding what tool to purchase. There has been little information on these different instruments and how accurate they are considering their price. This study looked at the Suunto Clinometer, Nikon Forestry Pro Rangefinder and the HagLof Vertex IV Hypsometer. These instruments were tested in different stand conditions that these tools would be used in. This study was done to help give more information to professionals about these measuring instruments and what instrument is better to use when considering their cost. The hypsometer was found to be the most accurate in both sites. The clinometer and range finder were found to be less accurate.

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.

Improvements and Operation of the Solar Lumber Kiln at Paul Smith’s College

Thu, 05/10/2018 - 14:45
Abstract: This paper aims to discuss improvements and operation of the solar lumber kiln in operation at Paul Smith’s College. It discusses what solar kilns are, the functions of a solar kiln, the types of solar kilns, and the basic principles of how each type operates. By understanding the functions and workings of a solar kiln, improvements for operation can be made to the existing kiln to increase effectiveness and efficiency. Subjects to be examined include preparation of wood for solar kiln drying, air flow within the kiln, the solar collector portion of Paul Smith’s College’s kiln, methods to make the kiln more air tight, and damages and malfunctions that have occurred within the first year of operation. Proposed improvements for both the operation of the kiln and preparation of lumber prior to drying in the kiln are provided, along with operating and construction information from Wood-Mizer, the company that designed Paul Smith’s College’s solar lumber kiln.

Recommendations for Extending the Winter Use of Dillon’s Sawmill at Paul Smith’s College

Thu, 05/10/2018 - 17:35
Abstract: This paper proposes a three-phase plan to update the Dillon’s Sawmill at Paul Smith’s College in the northern Adirondacks of New York State for extending winter use. The current issues are excessive airflow, hydraulic warmup time and potential damage, and safety of students and workers. Solutions were researched and compiled into a logical three phase plan. The first phase will be immediately within one year of proposal approval. Phase I will include installation of an added structure over log deck, two overhead doors, vinyl strip door, and two Wolverine Heaters. The second phase is from years one to five. This phase will include the installation of Ecofoil insulation in the walls and under the new roof. Phase III is the final phase and is from five to ten years after the update has begun. During this phase, closed cell spray foam insulation will be applied over the existing Ecofoil and an outdoor wood boiler will be installed. The total estimated cost for the updates to Dillon’s Sawmill is $57,264.70.

Drying Firewood in the Adirondacks: Development and Evaluation of Four Firewood Drying Systems for Use with the Solar Kiln at Paul Smith's College

Fri, 05/11/2018 - 05:59
Abstract: Four firewood drying system designs have been constructed for future use in the solar kiln drying process. A series of test were compared looking at structure and movement limitations to ensure the structure can withstand placement in the solar kiln. The comparison for each design was made in terms of key performance indicators such as air flow and circulation between the pieces of firewood. Proper moisture content in seasoned firewood is between 15-20%, while green wood when a tree is harvested is between 30-50%. Specific requirements were discussed in more detail, these being overall building, stacking, and drying rates with the over encompassing issue of mobility restraints. Moisture content levels were checked and measured by a moisture meter every day since the beginning of mid-April. All designs were created with respect to the solar kiln that is at Paul Smith's College for future use in promotional and fundraiser events.

Engaging Visitors Of Glenview Preserve With Interpretive Signage

Fri, 12/14/2018 - 11:42
Abstract: Glenview Preserve is a Lowland forest and Field property that boarders the Bloomingdale Bog. Implementing an educational system at the preserve would lead to more public interaction that would guarantee support for the Adirondack Land Trust’s mission objectives. This approach would involve the development of an interpretive day-use site, interpretive programs and signs, and an outdoor education space. For my portion I will be investigating how the Adirondack Land Trust can construct interpretive signage that is weather resistant and provides valuable content. The quality of the content will be evaluated using the National Association of Interpretation principles of POETRY. These signs will promote ALT’s mission objectives by encouraging people to make a difference after their visit through well-constructed and entertaining information. Visitors will donate money to ensure that having an educational system at the preserve is a leading concern of the Adirondack Land Trust’s management plan for Glenview Preserve.
