Forest Structure and Composition in the Smitty Creek Watershed
Wed, 12/14/2016 - 09:56
Abstract: The 2016 Smitty Creek CFI (Continuous Forest Inventory) study addressed the issue of creating a reliable and repeatable inventory design to examine general forestry trends and their relationships with the watershed itself. Identifying these trends and their consequences is important when considering factors linked to climate change, such as carbon storage and allocation. The objective of this project were as follows: establish 10 new CFI plots, monitor and record for signs of disease and insects, tree mortality, and overstory wildlife habitat, accurately estimate forest carbon sequestration, record understory composition in a 1/50th acre area around each plot center, and suggest methods and reasons for application in Paul Smith’s College CFI capstone projects. The study was conducted within the Smitty Creek watershed in Paul Smiths, NY with the plots falling on a transect that runs north and south. At each plot, trees within the radius were assigned numbered aluminum tags, trees were measured at diameter at breast height, and other features, such as snags, were recorded. Upon completing the project, 10 CFI plots had been created and their locations were recorded, several diseases and forest health concerns were identified, as well as, tree mortality and wildlife habitat considerations, carbon sequestration for the watershed was modeled over the next century, and a CFI project was designed for the Paul Smith’s College land compartments. The Smitty Creek watershed CFI project is repeatable and has an accurate baseline of information for future studies, and the Paul Smith’s College land compartments CFI plot design is ready for implementation.

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.

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.

A Paleolimnological study of precipitation variability in the Adirondacks over the last thousand years
Mon, 12/02/2013 - 20:40
Abstract: At present, most regional climate models anticipate wetter conditions by the end of this century, but a few models anticipate drier conditions. This study uses foresight to test these models, as well as describe the relationship between the dominant climate system in the region and past precipitation in the Adirondacks. Precipitation was inferred from diatom assemblages observed along a lake sediment core extending into the 1000 years. This study shows that abrupt, extreme wet events were common during the last 1000 years, and a relationship between the dominant climate system (North Atlantic Oscillation) and precipitation was irregular during the cool Little Ice Age but negatively associated during the warm Medieval Climate Anomaly. With temperatures in the Northeast projected to increase by 2-5 degrees C by 2100 AD, our study suggests the region may become more arid rather than wetter, opposite of what models currently suggest.

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.

Evaluating the Recovery of Lakes from Acid Deposition in the Adirondack Park
Mon, 12/02/2013 - 22:49
Abstract: Acid rain has been an environmental problem since the 1980’s and has been a core issue in the Adirondack Park located in the northern part of New York State. Acid rain is created by acidic gases from anthropogenic uses that mix in the atmosphere with precipitation and forms acid deposition. Acid Rain lowers the pH of water which has detrimental effects on the biota living within lakes. There is a general consensus that the chemistry of lake water is recovering from acid deposition, however, there have not been sufficient studies on the state of recovery from acid rain in the Adirondack Park or much of the United States. This study will investigate if lake recovery is indeed happening in the Adirondack Park. This study analyzed the water chemistry of lakes using data collected from the Adirondack Lake Survey Corporation (ALSC) and New York State Department of Conservation (DEC). The object of this study is to find a trend in the water chemistry and combine it with DEC data to evaluate the present condition of lakes within the park. The results showed that there are not significant correlations of the data besides SO42- concentrations, which have been approving in the park in the last 20 years.

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.

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.
