Cultural eutrophication of Lower Saint Regis Lake using diatoms and organic content as indicators of eutrophication.
Tue, 04/28/2020 - 12:06
Abstract: Cultural eutrophication can greatly affect water quality, leading to algae blooms and can affect fish communities. Throughout the history of Paul Smith’s Hotel and College, development along Lower St. Regis lake has led to increases in eutrophic conditions, which has detrimental effects on water quality. In this study, a sediment core from Lower St. Regis Lake was analyzed to determine when past eutrophication events occurred. This was accomplished using species counts of diatoms from every 1.0 cm of sediment. The relative abundance of diatom species such as Tabellaria flocculosa, Asterionella formosa, and Fragilaria crotonensis were used as indicators of more eutrophic conditions. Loss on ignition (LOI) was also used to measure the organic content in the sediment at increments of 0.5 cm. The higher percent lost on ignition indicates higher productivity in the lake and more eutrophic conditions. Some samples from the sediment core were also dated using lead-210 to create a timeline that could be compared to known dates of events occurring along the lake that could have affected the trophic status of Lower St. Regis Lake. There was a sudden spike in the relative abundance of F. crotonensis and an increase in organic content at a depth of 20 cm in the core, indicating that conditions became more eutrophic. Based on the lead-210 dates, this spike in F. crotonensis and organic content occurred between 1898 and 1908, when development around the lake was increasing and Paul Smith’s Hotel added indoor plumbing with poor wastewater treatment practices.

Black Ash Seed Management: A Potential Partnership Project
Tue, 05/12/2020 - 09:06
Abstract: The Emerald Ash Borer beetle is currently decimating Black Ash populations, which is making the species increasingly difficult to find. With the Black Ash species becoming increasingly rare, some management plans have been created to protect the remaining populations of this species. The Akwesasne Mohawk Tribe has a management plan in place that is not only trying to protect the remaining Black Ash but is also harvesting their seeds and growing new trees. Partnering with the Akwesasne Mohawk Tribe to grow Black Ash Trees would be a massive step in the fight to keep this species alive. My research will analyze the challenges and possibilities associated with entering into a partnership with the Akwesasne Mohawk Tribe in a joint effort to secure the Black Ash’s future survival.

Abstract: The purpose of this capstone was to look at the financial plan for the Alumni Campground and make suggestions for marketing. Through interviews, surveys, and other research on the campground, we were able to see who uses the campground and areas of improvement for the physical site and marketing. Our recommendations are to help the campground prosper in the future

Effects of Silvicultural Treatments on Wildlife Communities at the Paul Smith's College Forest Research Demonstration Areas
Fri, 05/11/2018 - 16:15
Abstract: Logging has drastically altered North American forest ecosystems for centuries. While extensive studies have been done to determine the impacts of different silvicultural practices on plant communities, minimal research has evaluated the impacts on wildlife communities, particularly in the Adirondack Mountains. Silvicultural practices may significantly impact wildlife communities due to the disturbances it causes, as well as the way it alters the habitat. We monitored winter wildlife communities in the Forest Ecosystem Research Demonstration Area owned by Paul Smith’s College in the Northern Adirondack Park. By analyzing the data collected by trail cameras, tracks and measuring percent browse, we compared the abundance and diversity of wildlife in three silvicultural treatments (i.e., clearcut, group selection, control). We also collected data regarding the physical aspects of the silvicultural treatment plot (i.e. canopy cover and snow depth) to indicate the kind of available habitat. We found that despite there being the highest average relative activity in group selection, there is no significant relationship between average relative activity and harvest treatment type. Using the Shannon-Weiner Diversity Index, we found that the highest diversity was in control/reference. Due to our limited treatment sample size, we did not have conclusive findings in most areas of our study. However, the highest total tracks and relative activity were found in the clearcuts. We suggest that more research be done on this study in order to eventually make forest management plans that properly account for both plant and wildlife species.

A Comparison of Winter Wildlife Use of Minimally, Moderately and Highly Impacted Shorelines on Lower St. Regis Lake and Black Pond in the Adirondack Park, NY
Wed, 05/09/2018 - 10:51
Abstract: Continued development and human interference with freshwater shorelines creates a degraded environment and can negatively affect native wildlife along impacted areas. Throughout the Adirondack Park, shorelines have experienced substantial degradation with the development of lakeside summer homes. There tends to be a strong preference for the aesthetics that lakes offer, as well as the numerous recreational opportunities they provide. The increased human use of shorelines and the development of anthropogenic structures has directly resulted in the degradation of shorelines in the Adirondack Park. Likewise, the Paul Smith’s College shoreline along Lower St. Regis Lake has been subjected to degradation throughout the history of the campus. This highly impacted site was selected, alongside minimally and moderately impacted sites in the surrounding areas as representatives for different impact levels. Shoreline degradation includes a decline in the health and presence of natural vegetation, creating a decrease in available food source for native wildlife. The removal of natural vegetation creates a decline in shoreline stability with the removal of root systems, allowing for greater amounts of erosion to occur. Additionally, degradation decreases available canopy cover and increases exposure of wildlife to predation. The objective of this study was to determine the difference in wildlife activity and diversity between three levels of shoreline impacts: minimal, moderate, and high. It was expected that the minimally and moderately impacted shoreline sites would show a greater diversity and abundance of wildlife than highly impacted shorelines. Trail camera data was analyzed at three sites for each treatment on Paul Smith’s College property, along both the Lower St. Regis Lake and Black Pond. Although we detected no significant differences in either activity or diversity across the treatments, there was higher relative activity and diversity in moderately impacted shorelines than minimally or highly impacted. However, wildlife species that are more rare and/or area-sensitive, such as the fisher (Martes pennanti) and American marten (Martes americana), were only detected in the minimally impacted shorelines of Black Pond. A restoration of the highly impacted shoreline to reflect minimally and non-impacted shorelines of the surrounding region would allow for opportunities to improve habitat for native wildlife species.
