The Lawns at Paul Smith’s College: The Effects of Mowing on Root Biomass and Soil Compaction

Mon, 12/07/2020 - 17:41
Abstract: Lawns are a valuable aspect of real estate in the United States. Maintained lawns cover over 163,000 square kilometers of land, yet few people realize the impact mowing can have on the ecosystem. This study will be looking at the impact of mowing on the grassland ecosystem and the terrain grassland ecosystem at Paul Smith’s College, located in Paul Smiths, New York. This study will be testing two different factors that are impacted by constant mowing on campus: soil compaction and root biomass of flora found on the sites. Soil compaction is the compression of soil due to large amounts of pressure placed on the surface soil. This event will be tested by using a soil bulk density test. The root biomass is being investigated by the use of a scale to weigh root given from each area of the study site. The study goal is to find out how the disturbances of mowing affect the grassland ecosystem found at Paul Smith’s College using two different factors: soil compaction, root biomass. The results of the study show the site type that has the greatest soil bulk density and the lowest dry root biomass in G/〖cm〗^3 is the dry slope site on the campus. Keywords: lawn ecology, effect of mowing, soil compaction, root biomass, root depth

Developing a Bird Integrity Index (BII) for Use as an Indicator of Stream Condition in the Northern Adirondack Park

Mon, 04/27/2020 - 12:50
Abstract: The primary goal of this research was to create a Bird Integrity Index (BII) to be used for the ecological integrity analysis of streams and their related riparian zones in the northern Adirondack Park based on frameworks provided by previous research in Oregon. Fifty-eight metrics were tested from avian survey (point count) data along fifteen stream reaches of 0.5km in length. These metrics represented aspects of avian taxonomic richness, dietary preferences, foraging techniques, tolerance or intolerance to human disturbance, and nesting strategies. To evaluate the responsiveness of each metric, they were plotted against an index of stream condition based on sampling of benthic macroinvertebrates according to the outline provided by the stream biomonitoring research unit of the New York State Department of Environmental Conservation. Five of the fifty-eight candidate metrics remained after removing metrics that had an R2 value of less than .2 or were highly correlated. Individual avian metric scores ranged from 0-10 and BII scores were set on a scale of 0-100. While the BII presented here was successful in responding to varying conditions based on disturbance levels (R2= .64), due to multiple unexpected relationships between avian metrics and stream condition, it is proposed that more in-depth and comparative research be completed before an Adirondack specific BII is presented for field usage.
