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.

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.

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.

Mycoremediation Potential of Pleurotus ostreatus in Logging Operations

Mon, 05/02/2016 - 10:43
Abstract: The unintentional spillage of diesel and hydraulic fluid is an unfortunate part of forestry operations and the traditional cleanup methods can be costly. Many studies have shown that white rot fungi (WRF) are capable of breaking down a wide variety of environmental pollutants, including diesel fuel. The purpose of this study is to evaluate the ability of a WRF, Pluerotus ostreatus, to breakdown hydraulic fluid. Soil and sawdust were mixed at a 1:1 ratio and jars had, 0%, 3%, 5% and 10% of their volume added in hydraulic fluid. All jars were fully colonized within two weeks and after 30 days the concentration of residual hydrocarbon was analyzed with an extraction. The results showed that the maximum degradation of hydraulic fluid occurred at 5%. In addition sawdust spawn was dehydrated at different temperatures, in order to assess possible field application. The only dehydration test that grew was the air dried sample.

Growth of Black Spruce and Tamarack in Response to Abiotic Variables

Tue, 05/03/2016 - 12:46
Abstract: The growth of black spruce (Picea mariana) and tamarack (Larix laricina) was examined in relation to the potential influences of pH, dissolved oxygen, conductivity, water temperature, proportion of canopy closure and depth to ground water in a northern Adirondack peatland ecosystem. 42 plots were constructed in a sphagnum dominated wetland and sampled for the above abiotic variables throughout the summer and fall of 2015. Heights, ages and periodic annual increment of 26 tamarack and 23 black spruce samples were determined in February and March of 2016. An age to height ratio and periodic annual increment for each species was then regressed against the above abiotic variable data in order to determine any influence of these data on growth rates of the conspecifics. Results show that depth to water table and increased exposure to light had a significantly positive relationship with the age to height ratio of tamarack. Periodic annual increment of tamarack had a significant positive relationship with decreasing light exposure. Black spruce’s age to height ratio had a significant positive relationship with dissolved oxygen (mg/L).

Best Management Practices for Cultivating Cold-Weather Shiitake Strains in the Adirondack North Country

Fri, 05/01/2015 - 09:55
Abstract: Shiitake (Lentinula edodes) cultivation has become an important tool for private woodlot owners to diversify their income and manage their woodlots more efficiently and sustainably. Through the art and science of mushroom cultivation three strains of shiitake have been created for varying climates: Wide Range (WR), Warm Weather (WW), and Cold Weather (CW). This study proposes that CW strains would be most ideal for the Adirondack North Country because growing conditions now and in the future are nearly optimal. CW strains have a shorter fruiting period (spring and fall) than the WR and WW; therefore, the mushroom production potential of the CW is underutilized. In order to get maximum production of their logs, most growers use a method called shocking to induce fruiting with WR and WW; however, research has shown that shocking does not trigger fruiting in the CW strains; rather, CW strains respond to temperature fluctuations. Taking this into account, we’ve introduced a hybrid approach of growing CW shiitake, which combines outdoor and indoor cultivation techniques to best imitate that temperature fluctuation. Growing CW shiitake using a hybrid approach can be the best choice for small-scale growers who wish to extend their growing season into the winter months, thus opening new market opportunities. By conducting interviews with shiitake growers in similar climates and compiling and analyzing literature from other professionals, we have gathered data on log harvesting, laying yard conditions, moisture management, and lighting conditions and developed a best management practices guide for small-scale shiitake grower/woodlot owners in a northern Adirondack climate. Ultimately, growers could diversify their sources of income, provide incentive to manage their woodlots and most importantly learn how to effectively utilize CW strains through the winter months.

A Forest Management Plan For Lynn Woods Reservation

Sun, 04/27/2014 - 18:49
Abstract: Lynn Woods Reservation located in Lynn, MA (42°29' N, 70°59’ W) is a 2,200 acre municipal park under the joint management of the Lynn Parks Department and the Lynn Water and Sewer Department. Since 1881, there has been little management on the lands of the reservation. This project developed a forest management plan for the Reservation. A forest inventory took place in January 2014 utilizing SilviaTerra’s Plothound data collection app. Data was then processed in NED-2 and ArcGIS to create final data used in the creation of this plan. The tract was divided into three compartments based on location and access. Multiple stands are inaccessible or do not contain merchantable timber but most of this tract is harvestable. Based on the data collected, suggested silvicultural prescriptions were developed along with other management suggestions for the tract. This plan was submitted to the park ranger, Dan Smalls, for review and final implementation.

A Genetic Comparison of Two Populations of American Beech (Fagus grandifolia) Impacted by the Invasive Disease Complex Causing Beech Bark Disease

Mon, 04/28/2014 - 23:35
Abstract: Many mature American beech trees have died due to beech bark disease throughout the northeastern United States. However, there are many pockets of beech trees throughout its native range that show resistance to the disease. This study will be focused on comparing specific genetic markers in a variety of American beech trees which have been categorized by the levels of severity of beech bark disease per individual tree. Leaf and bud samples were taken in October 2013 from 30 individual trees with varying degrees of disease severity. DNA will be purified from these soft tissue samples in order to use PCR and focus on 5 microsatellite locations for a comparison between all individuals being sampled. These loci will help to determine the genetic differences and similarities between American beech trees with and without signs of resistance to beech bark disease. The results of this study will set the stage for a landscape level study in the future, as well as further studies on finding genetic markers for resistance.

Developing a Log Rule for Portable Sawmill Operators in Vermont

Fri, 04/26/2013 - 10:30
Abstract: Since the beginning of the 19th century, American lumbermen have been vexed by one of the unique questions of their trade; how do you estimate the yield of squared lumber to be cut from a round log? Since 1825, answers to this question have come in the form of log rules; a table or formula that estimates the yield of logs. These tables are in no way universal, and in some cases are crudely inaccurate. The shortcomings of these log rules have manifest differently in the various geographic locales and industry sectors where they are used. This study sought to identify such shortcomings as they pertain to a specific group of lumbermen; portable sawmill operators. These sawyers utilize modern bandsaw technology and have unique business practices, yet they estimate outputs based on century old log rules created for traditional sawmills. Through the use of semi-structured open ended interviews, technical and socioeconomic information was gathered from 7 sawyers in Vermont. Among other concerns, five of the sawyers expressed the need for a better way to estimate log yield. Based on their collective suggestions and technical approaches, a new log rule was created here to address sawyers’ needs.

Sharing the John Dillon Park Experience with More Visitors: A marketing and management strategy, to increase visitor usage concentrating on organizations for people with disabilities and Veterans

Mon, 04/16/2012 - 17:54
Abstract: International Paper John Dillon Park (JDP) is a fully accessible campground managed by Paul Smith's College (PSC). Fully accessible means it was designed so anyone, regardless of the presence of a disability, can utilize the facility. The campground has not been near full capacity since it was opened in 2006. PSC wishes to increase those visitor numbers concentrating on Veterans and organizations for people with disabilities. A survey was conducted of the current park visitors to obtain information needed to help define the desired demographic and other information needed for the marketing strategy of JDP. These visitor responses showed that PSC needs to concentrate its marketing efforts into better contact with its current users to stimulate return users, make a few changes to the facilities themselves, and advertise within magazines, Veteran organizations, organizations for people with disabilities and Fort Drum. Also, the responses informed PSC that it needs to provide for the recollection phase of the recreational experience by selling JDP souvenirs. With an increase in the visitor usage of JDP, more people will be able to appreciate the serenity of nature and the camping experience JDP offers to all people.
