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.

Influence of Slope on Soil Organic Carbon on Costa Rican Coffee Farms.

Mon, 05/07/2018 - 10:21
Abstract: Soil management is an important factor on agroforestry farms that help with soil fertility and carbon storage. Coffee agroforestry farms in Central Valley Atenas, Costa Rica were analyzed between November 2008 and May 2017. The objective of this study was to see if there is a relationship between mean slope and annual soil organic carbon sequestration (Mg/ha), and mean slope and soil organic carbon storage (Mg/ha), from samples taken on November 2008/May 2009 and November2016/ May 2017. Sample were taken on five farms with twenty 0.05 ha plots. Many coffee farms in the central valley are assembled on steep slopes or sides of mountains. Steep slopes are susceptible to erosion affecting the amount of soil organic carbon sequestration and storage. There was not a significant relationship found between mean slope and loss of carbon sequestration annually in November 2016/ May 2017 (Mg/ha). Mean slope and soil organic carbon storage from November 2016/May 2017 were compared by testing the effects of slope with carbon storage and there was no relationship. Whereas a statistically significant positive relationship was found between mean slope and soil organic carbon storage from November 2008/ May 2009. Additional data was examined to look at annual carbon sequestration loss on conventional and organic farms. However there was not a significant difference between the two. When all farms were compared for their annual carbon sequestration loss, marginally significant difference was found, but reasons for these differences remain a hypothesis. Further research to examine these differences may include practices of the farmers and erosion steeper slopes before erosion implications were taken by the farmers.

Limnological Report of Marvin (Potters) Pond

Thu, 04/30/2015 - 09:51
Abstract: Long term data of limnological conditions is crucial to understand lentic freshwater ecosystems. Marvin (Potters) pond is a 2.04 hectare kettle pond located in Franklin County, New York in the Northern Adirondack Park. There have been numerous short studies of the pond over the past 30 years but the pond has never been intently monitored to date. The pond is assumed to be meromictic by the NYSDEC. The objectives of this study are to 1) calculate the morphometry of the pond and its watershed; 2) the determination of the trophic status of the pond; 3) to document the chemical composition of the pond, particularly as it relates to acidity and acid neutralizing capacity; 4) to document the annual dynamics of temperature and dissolved oxygen. Evidence from profile data on dissolved oxygen and total iron suggests that the pond is monomictic with the capability to be meromictic under certain climatic conditions. The mixing period of the pond occurred in the month of November. The morphometry of Marvin pond was found to have a conical cross sectional area and large depth for the surface area of the pond. The trophic state of Marvin pond was found to be eutrophic for chlorophyll-a and total phosphorus concentrations but mesotrophic for the secchi disk reading. The acidity of the pond was found to be high with a low buffering capacity.

Trophic status of Lake Placid over the past 2740 + 30 years inferred by sub-fossil diatom analysis.

Thu, 04/30/2015 - 11:07
Abstract: The hypothesis of this study was that human activity in the Lake Placid watershed would cause changes in the lakes trophic status. Trophic status was inferred by changes in diatom assemblages over time. This analysis shows that an unusual increase in Asterionella and Tabellaria has occurred within the past 200 years. Both of these species are indicators of higher trophic status, so their increase in numbers indicates a recent increase in trophic status (Stager 2001, Rawson 1956, Stevenson et al, 1982). Loss on ignition tests were used to determine the organic content of samples from two cores. These tests showed that organic content has varied in the past, however changes observed in the upper 20 cm of the record for Lake Placid and Wolf Lake suggest that human activity impacted the lake. The data collected in this study supports the hypothesis that human settlement in the Lake Placid watershed has changed its trophic status.

Assessing Activities and Policies to Improve Outing Club Participation

Wed, 04/29/2015 - 19:48
Abstract: College outing clubs have proven to be very beneficial for college students of all ages and fields of study. Research shows that outing programs, outdoor education programs, and adventure education programs can have a terrific impact on student’s mental, physical, and spiritual health. This study aims to assess activities and policies that could potentially increase participation in the outing club of Paul Smiths College in the Adirondack Mountains of Upstate New York. The questions this study intends to answer are: 1.) What types of activities will cause an increase in participation? 2.) What types of qualifications & experience should be required of guides and group leaders? and 3.) What can we do to increase organization or professionalism of our program? Using surveys, interviews, and credible sources, this study collected data from successful college outing clubs, the Paul Smith’s student body, and professionals in the field of recreation and summarized it into one collection of results with intentions of exposing ways to increase participation in the program and increase professionalism and organization of the program. Results exposed reoccurring themes regarding expectations for guide training, activities provided through other successful programs, and activities suggested by the student body. The student body survey revealed high support of technical skills seminars to teach students technical backcountry skills in a shorter period of time, and a high demand for high intensity activities such as white water rafting. Many responses supported the fact that in order to increase popularity in a program, the activities need to be demanding enough that individuals aren’t likely to partake in the activity without prior organization and qualified leadership. The results and data found in this study can be used in the future to develop outing club policies and procedures to aid in the success of the program.
