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.

Monitoring the Zebra Mussel Invasion Front: Use of New Technology

Thu, 02/09/2012 - 15:39
Abstract: Zebra mussels are invasive mollusks that are affecting the well-being of the water bodies in the United States. This study uses environmental DNA (eDNA) is a sensitive early detection system that may be useful in monitoring their spread. The purpose of this study is to determine the effectiveness of eDNA technology in identifying infested water bodies, to determine if zebra mussel DNA is in the Adirondack water bodies not known to be infested, if the water chemistry of these water bodies is favorable for zebra mussel establishment, and if the eDNA technology is transferable to an institution like Paul Smith’s College. Eighteen lakes, all in New York State were sampled, fifteen of which are located in the Adirondack Park. DNA was extracted from water and plankton samples and species specific primers were used for PCR amplification to determine if zebra mussel DNA was present. Of seven samples taken from sites known to be infested, five of these tested positive for zebra mussel eDNA. Four lakes not known to be infested within the Park also tested positive for zebra mussel eDNA. Based on zebra mussel risk parameters (water chemistry) applied to 1,469 Adirondack water bodies, less than 3% are at risk of zebra mussel establishment. However it is possible that established populations could occur at microsites that may have locally high levels of calcium and higher pH.

Promoting Conservation of Biodiversity in the Adirondack Park Through Understanding and Engaging Stakeholders

Thu, 02/09/2012 - 11:31
Abstract: Anthropogenic disturbance of natural environments has led to the widespread loss of native biodiversity and degradation of ecosystems. It is increasingly recognized that addressing this “biodiversity crisis” entails understanding the societal drivers of unsustainable patterns of use. Conservation psychology is a new discipline that specifically focuses on understanding the linkages between human behavior and action and promoting a healthy and sustainable relationship between humans and nature. In this project, we employed principles of conservation psychology with the goal of improving the efficacy and efficiency of conservation of biodiversity in the Adirondack Park (AP). To meet this goal we employed three specific strategies. The first of these strategies was the use of surveys to assess the values, attitudes, and actions different stakeholders have in regards to conservation of biodiversity in the AP. These surveys were disseminated via both direct mailings and online, and included 30 questions. Our second strategy was to use discourse analysis to create a dictionary of terms and phrases employed in a positive, neutral, and negative light in regard to conservation of biodiversity. This entailed analysis of 30 emic accounts derived from opinion articles written by stakeholders in the AP, as well as analysis of a number of etic accounts drawn from online sources. Our third strategy was to use conservation psychology literature to assess ways in which the presentation of information and peer-dynamics influenced the responses of stakeholders towards conservation of biodiversity. Using the combination of these three strategies, we were able to provide a holistic understanding of how different stakeholders in the AP perceive and act towards biodiversity conservation; identify language that can be used to illicit a more positive response from these stakeholders; and identify specific tools based on principles of psychology that can encourage more active and effective engagement in conservation of biodiversity by different stakeholders. Our research findings will allow groups focusing on promoting conservation of biodiversity in the AP to be more effective and efficient in their work in the future.

Removal of Japanese Barberry (Berberis thunbergii) in a Hardwood Forest in Northwest Connecticut

Mon, 12/05/2011 - 09:57
Abstract: Japanese barberry is an invasive shrub that has overtaken and invaded the forest land of New England. Once established, Japanese barberry grows into dense populations that affect forest regeneration, and availability of different nutrients in the soil. This study focused on determining the most time efficient way to remove Japanese barberry from an area. The amount of time it took to complete each removal method was compared with how effective each method was. The effectiveness of each method was based upon how many stems were removed, and how many stems sprouted after a treatment occurred. Four methods were used which included; root severing, cutting stems, burning stems and a herbicide foliar application. It was found that digging stems took a large amount of time, while stem cutting and burning took a moderate amount of time, and the use of herbicide took a small amount of time. It was found that root severing was the least effective method, producing a high amount of new stems and taking the longest time. Herbicide treatment of stems was the most effective method, producing no new stems after treatment and taking a short amount of time to complete. Out of all the methods, two methods had equal expenses. This study has determined the most efficient and least effective way to remove Japanese barberry from a typical New England hardwood stand.

An Investigation of Soil Nutrient Concentrations and its Relations to the Possible Sugar Maple (Acer saccharum) Decline in the Paul Smith’s College Sugar Bush

Mon, 12/05/2011 - 11:50
Abstract: Sugar maple (Acer saccharum) is an abundant tree specie that can be found almost everywhere in New England. Sugar maples can be used as timber logs, but they are primarily a great source for producing maple syrup. These trees are a vast source of income for a lot of people. Paul Smith’s College annually produces range from $25,000-$30,000 from the syrup production at their sugar bush. There are currently 1400 taps out in the sugar bush. The purpose of this study is to determine if sugar maples are on a decline in the Paul Smith’s College Sugar Bush. There have been many tests and studies done on variables that affect sugar maple growth. Many different variables such as the effects of climate, nutrient concentrations, light, ozone, oxidative stress, elevated CO2, precipitation, other trees, invasive species and mycorrhizal fungi were studied to determine how they affect soil nutrient concentrations, which ultimately affects the ability of sugar maple to survive and thrive. These studies have shown that sugar maples in New England are on a steady decline. All of the studies I have found have focused on the big picture in regard to sugar maple decline, and none on the local level, like the Paul Smith’s College Sugar Bush. The purpose of my study is to determine whether or not the sugar maples in the sugar bush are on a decline and if they are will that information influence the college’s management plan for its sugar bush. This project collected and developed data that helped determine whether sugar maples in the sugar bush are on a decline. With this new information the college will be able to determine what they would like to do with the sugar bush in the future years to come.

Effects of Forest Cover Type on Carbon Sequestration Rates

Mon, 12/05/2011 - 14:42
Abstract: Climate change and mitigation of climate change are common dilemmas faced by the majority of people within the United States. At the heart of climate mitigation techniques are forestry practices aimed to promote increased carbon sequestration. Forests are effective at sequestering carbon because they act as carbon sinks for the majority of their life. The purpose of this study was to examine the effect that Northeastern forest cover types have on the rate of carbon sequestration. This was done by examining the major forest cover types: northern hardwoods, mixed woods, and conifer forest cover types within Vermont and New Hampshire. This study entailed timber sampling to determine the amount of above ground carbon, increment boring to determine growth rates, soil samples to calculate subsurface carbon, and forest floor samples to determine accumulated carbon in the forest floor. During the study it was found that the conifer stands exhibited the highest rate of carbon sequestration, attributed greatly to the high growth rates and high stocking densities that characterized these stands. In addition, the majority of carbon within all the stands was found to be within the forest soils, which indicates particular attention should be given to this area when managing for carbon sequestration. In conclusion, some suggested management techniques for increasing carbon sequestration rates could include extending the rotation age to capitalize on the entire accelerated growth stage of the trees, and promoting multiple age classes within the stands which would allow for less intensive harvest regimes.
