Forest Succession's Effect on Soil Physical and Chemical Properties after Agriculture Abandonment

Mon, 12/01/2014 - 11:00
Abstract: Landscapes have been significantly altered by humans and replacing forests with agricultural crops is a major alteration humans have made. This landscape change has affected soils significantly. Agriculture practices can potentially have detrimental effects on soils. However, through the 20th century forest cover drastically increased in the United States through the recruitment of second growth forests as a result of agriculture abandonment. Forests reclaiming farm lands through forest succession can have a significant effect on recoveries in soil physical and chemical properties such as bulk density, soil strength, porosity and fertility. Therefore, the goal of this study was to investigate forest successions effect on soil physical and chemical properties after agriculture abandonment. Three specific hypotheses were tested: 1) Bulk density and soil strength will decrease while micro and macro porosity will increase as forests reclaim farm lands. 2) Soil carbon and available nitrogen will increase over time. 3) Soil pH will decrease and electrical conductivity will increase over time. These hypotheses were explored on abandoned agriculture fields in a chronosequence study on coarse loamy Inceptisols in upstate New York across a 60 year temporal scale. Data showed that total porosity, total carbon and available nitrogen increase while soil pH, bulk density, soil strength and electrical conductivity decline over time. These results support all three hypotheses except for the latter half of hypothesis number three. The findings of this study suggest that although agriculture may disturb soil properties, time coupled with forest succession can result in significant recoveries.

Alpine Ecosystems on Ski Area Summits in the Northeast: A Best Management Practices Manual

Mon, 12/01/2014 - 15:19
Abstract: Over the past half a century, anthropogenic climate change has triggered temperatures in the northeastern United States to rise. This increase has led to decreased winter precipitation and a longer annual growing season. Species found in upland/montane habitats on the southern edge of their range limits are particularly threatened by these changes. Warmer temperatures have allowed larger woody plants to advance up mountain slopes, entering the habitat of these fragile species. In the next decade, we will witness a complete disappearance of alpine flora from several locations across the northeast including Whiteface in New York, Sugarloaf in Maine and Mount Mansfield in Vermont. Managers of ski resorts can therefore play an important role in promoting the continued persistence of high-altitude flora and fauna through carefully considered management decisions can also serve to promote the reputation of the ski industry as stewards of mountaintop ecosystems. Doing so will allow for continued study of the species that exist within these communities, the protection of biodiversity, and increased revenue for the resort itself through elevated public image and mountain-top tourism. To help begin these conservation efforts, we have created a best management practice (BMP) manual to guide ski area managers in making these developments. It includes techniques for sustainable slope, soil, vegetation and wildlife management, erosion control, artificial snow production, and ski slope construction and design. Also included are marketing techniques and an overview of the economic viability of the practices outlined in this manual.

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.

Differences in soil fertility along roadsides between state and locally managed roadways in Franklin County, New York

Thu, 05/08/2014 - 20:30
Abstract: Techniques for managing roadways often incorporate use of sodium chloride, or roadsalt. Use of this substance can vary greatly depending on whether state or local municipalities are prescribing management for particular roadways. Roadsalt has the potential to affect the chemical composition of roadside soils. This study sought examine relationships between winter management techniques and soil chemical properties as distance increased from roadsides. Transects were set up perpendicular to 5 roads managed by the State of New York, and 5 roads managed by towns in Franklin County, New York. 10 samples were removed from the soil surface at each transect, every two meters back from each roadside from 2 to 20 meters. pH, conductivity, abundances of Ca, Na, K, Mg, Cl, % Na on CEC, & % Ca on CEC were determined for each sample. Using ANOVA equations pH, % Na, and Cl concentration were found to have significant relationship with distance while %Na, % Ca, and Na concentration had significant relationships with regards to management. It was concluded that Na is displacing large amounts of Ca on exchange near state managed roads, decreasing soil fertility specifically in those areas. Results follow trends found in other studies that cite increasing concentrations of both Na and Cl on watershed scales.

The Effects on Soil Caused by Garlic Mustard (Alliaria petiolata) in a Northern Hardwood Forest in the Northern Adirondack Mountains

Mon, 12/02/2013 - 10:54
Abstract: Plant invasions are thought to be among the worst causes of biological extinction and biodiversity loss in the modern world. With the United States spending upward of thirty four million dollars a year in attempts to control and repair the damages caused by invasive plants, not only are we feeling the biological effects, but we financially cannot afford to keep combating these invasive species (Barto and Cipollini, 2009). Garlic mustard (Alliaria petiolata) can invade multiple types of sites whether the soil is sandy or if a site has been disturbed. This invasive species will take over the understory and alter soil chemistry (Morris, McClain, Anderson and McConnaughay, 2012). This study aimed to look at how garlic mustard is affecting soils in the northern Adirondack Mountains in New York State. Although currently scattered and not very prevalent, there have already been changes to the soil chemistry. This study was conducted by setting up multiple plots within areas where garlic mustard was present and gathering soil to be used to test for nutrient values. It was found in this study that calcium, phosphorous, magnesium, potassium, sodium, aluminum and soil pH values changed due to the presence of garlic mustard.

Determining Habitat Suitability for Ruffed Grouse (Bonasa umbellus) in Five Forest Harvest Method Plots on the Paul Smith’s Visitors Interpretation Center Land to Promote Long Term Suitable Habitat.

Sun, 04/28/2013 - 11:42
Abstract: Ruffed grouse (Bonansa umbellus) populations are in a steady decline due to the loss of early successional forests. Our study focused on the suitability of ruffed grouse habitat which is considered an area with adequate food and cover in. We used a habitat suitability index designed for ruffed grouse in Colorado that included average height of woody stems, percent conifers, density of mature yellow birch, and total equivalent stem density as the variables that indicate whether an area has suitable cover and food for ruffed grouse. Using the habitat suitability index we measured the vegetation in five forest harvest methods including: single tree selection, two-age cut, shelter-wood cut, clear-cut, and a control plot to determine if a habitat suitability index developed in Colorado can be used to assess habitat suitability for ruffed grouse in New York. These plots are located in the Adirondacks in Northern New York State at the Paul Smith’s College Visitors Interpretation Center (VIC). Our results suggested that 14 years after harvest a single tree selection harvest method has the highest overall habitat suitability (0.95) for ruffed grouse. This is different from other studies we found that indicated clear-cut was the most suitable forest harvest method for ruffed grouse. We also projected the change in habitat suitability for height of woody stems over time for the clear-cut based on the yearly growth rate of 0.656 feet. Based on our findings from the study we made recommendations to land owners and land managers to develop and promote short term and long term suitable habitat for ruffed grouse. These recommendations included using a variety of forestry practices that included: single tree selection, shelterwood, and clear-cut because ruffed grouse require a variety of different cover types and habitat over their lifetime.

Current State of the Black Ash Stand on Heaven Hill

Fri, 12/06/2013 - 01:06
Abstract: This study was conducted to assess the health and current state of the rare black ash (Fraxinus nigra) tree species on Heaven Hill property located in Lake Placid, New York. Little is known about black ash trees ecologically, it is mainly known solely for its cultural significance in basket making by the indigenous. Therefore, to learn more about the intricacies of black ash twenty fixed area plots were used to characterize the overstory in the 4 acre black ash stand. Diameter at Breast Height (DBH), crown class, crown condition, bark depth, and basket quality were measured. One black ash tree and one tree of another species were cored in each plot to analyze annual growth rings. Age of black ash trees was derived from the rings along with average ring growth per decade. Using the computer program, NED-2, basal area per acre (sq. ft) and stems per acre were calculated for the black stand. There was found to be a drop in stems per acre and basal area per acre after the seven inch diameter is met. Poor crown condition was found to be very low in black ash trees and even lower with an increase in DBH; 0% of the black ash trees between 11.5” and 17.5” DBH had Poor crown condition. Basket quality was assessed for each black ash tree and was based solely on physical features observed in the field. Basket quality for the stand was nine percent which represents the range in DBH classes from 5” to 15”. Only sixteen black ash trees were found to be potential basket quality trees.

Draft Horse Sustainability Presentations: The effectiveness of presentations on draft animal power at the Adirondack Rural Skills and Homesteading Festival

Fri, 12/06/2013 - 12:53
Abstract: Paul Smith’s College has been putting on draft horse presentations for the public for many years but until now it was unknown how effective these were in education of the audience in topics of the interest. During the 2013 Adirondack Rural Skills and Homesteading Festival, a series of demonstrations and presentations were conducted for the public. Surveys of those in attendance have now given us information on how far people are traveling, what their prior experience is, what they want to learn, and how they want to learn it. From this information we wish to gauge attendees’ response to draft animals and their uses.

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.
