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.

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.

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.

Alternative Management Methods for Acid Deposition in Lakes

Fri, 04/26/2013 - 18:09
Abstract: Acid deposition has been causing the acidification of lakes in the Northeast United States for decades. The result is lake ecosystems with abnormally low pH that stresses the organisms that live there. Management plans in place in the Adirondack Park have been working to remediate acidified lakes for the past few decades. Limestone (CaCO3) has been the generally accepted method for managing these lakes, in an attempt restore the lakes pre-impacted conditions. The purpose of this study was to evaluate the effectiveness of liming in reversing the effects of acidification, and to identify effective alternatives. Five alternatives were tested against limestone: Sodium carbonate (Na2CO3), Sodium bicarbonate (NaHCO3), Sodium acetate (CH3COONa), Magnesium carbonate (MgCO3), and Potassium carbonate (K2CO3). Double End-Point Titration tests were performed on all of the compounds, using both distilled water and lake water, to determine the relative alkalinity of each compound. Alkalinity is the measure of the ability of a solution to neutralize acid, also known as its "buffering capacity." Lake water was used in the titration tests in an attempt to mimic in-situ testing. The results of the titrations showed limestone proving to be the most effective in the lake water tests, with Magnesium carbonate and Potassium carbonate ranked closely behind. While limestone has proven to be an effective management method, its reliability is dependent upon the characteristics of the lake catchment, making it important to continue to look for alternative solutions.

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.
