Analysis of common water sampling techniques used to assess lake trophic state

Sat, 12/05/2015 - 00:21
Abstract: Volunteer lake management programs (VLMPs) across the country employ different surface water sampling techniques to establish long-term trends in nutrient availability and trophic state. The three most common techniques are a surface grab (SG), 2m integrated tube sampler (IT), and a discrete sampler, such as a Van Dorn or Kemmerer bottle deployed to a depth of 1.5m (DD). These various sampling techniques vary not only in depth, but also in cost and ease of use. The objectives of my study are to 1) determine if there is a statistical difference in chlorophyll-a (chl-a) and total phosphorus (TP) concentration obtained between the three different sampling techniques, 2) determine if the treatment effect (sampling device) varies over time, 3) determine which method has the least amount of variability, and 4) determine if sampling technique ultimately influences trophic state classification. The study was conducted on Upper St. Regis Lake, Paul Smiths, New York. I collected 10 samples from the lake using the three different techniques during the months of June – August, 2015. I found a significant difference in chlorophyll-a concentration between sampling techniques during June and July, and during the month of July for TP. The three sampling techniques yielded similar variability for chlorophyll-a but significantly different variability for TP. Ultimately, the trophic status rating for Upper St. Regis was not effected by sampling technique. My study suggests that VLMP should utilize a SG or IT rather than a costly DD sampler.

Interpreter's Guide to the Finger Lakes Trail

Wed, 04/29/2015 - 21:44
Abstract: Guidebooks help hikers to navigate trail systems and gain a better understanding of their surroundings. Many types of guides exist for popular long distance hiking trails such as the Appalachian Trail, the Pacific Crest Trail, and the Continental Divide Trail. The Finger Lakes Trail (FLT) runs 558 miles across the base of New York State, yet has very little associated literature. I hiked a 52 mile section of the Finger Lakes Trail from Ellicottville to Portageville in western New York. Using observations from the trail and related literature, I wrote an interpretive guide for this section. My FLT interpretive guide covers topics related to planning and packing for a multiday backpacking trip, natural history of western New York forests, the story of the development of the FLT system, and backpacking ethics. This work will help satisfy the human need to acquire knowledge and potentially enrich the experience of FLT hikers.

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.

Effects of Reduced Turbidity and Suspended Sediment Concentrations on Macroinvertebrate Communities at a Restored Reach on Warner Creek

Fri, 05/01/2015 - 18:21
Abstract: A segment of Warner Creek, a tributary to the Stony Clove Creek in the Catskill Mountains of New York, was restored in 2013 to reduce concentrations of suspended sediment and turbidity caused by a localized mud boil erosion of a large clay bank. Before restoration, impaired water-quality from fine sediments may have adversely affected intolerant species of macroinvertebrates and their communities. This study compared macroinvertebrate assemblages from before (2011) and after (2014) restoration to determine if the restoration reduced concentrations of suspended sediment and turbidity sufficiently to improve the health of their macroinvertebrate communities. The New York State Department of Environmental Conservation (NYSDEC) kick-sample methods were used to collect four replicate benthic invertebrate samples from Warner Creek and from a reference site on the Stony Clove Creek during August of 2011 and August of 2014. Four replicates of 100 specimens were identified to the family level from each replicate. The NYSDEC Bioassessment Profile scores and selected macroinvertebrate community metrics and turbidity and suspended sediment concentrations from a USGS stream gage downstream of the restoration both pre and post restoration were evaluated to test hypotheses that water quality and the health of macro-invertebrate assemblages differed post-restoration. Although some families at Warner Creek with low tolerance values were found to have increased post-restoration, it was also found that others with moderate tolerance values decreased. These types of fluctuations were seen in both years at both Warner Creek and the reference site, which makes it impossible to definitively say the impact restoration had on the macroinvertebrate assemblages one year post restoration. At this time it is obvious from the stream gage data that restoration significantly decreased turbidity and suspended sediment concentrations (SSC). Further collection of invertebrates and stream gage comparison is necessary to see if restoration does eventually impact the assemblage of invertebrates.

Best Management Practices for Cultivating Cold-Weather Shiitake Strains in the Adirondack North Country

Fri, 05/01/2015 - 09:55
Abstract: Shiitake (Lentinula edodes) cultivation has become an important tool for private woodlot owners to diversify their income and manage their woodlots more efficiently and sustainably. Through the art and science of mushroom cultivation three strains of shiitake have been created for varying climates: Wide Range (WR), Warm Weather (WW), and Cold Weather (CW). This study proposes that CW strains would be most ideal for the Adirondack North Country because growing conditions now and in the future are nearly optimal. CW strains have a shorter fruiting period (spring and fall) than the WR and WW; therefore, the mushroom production potential of the CW is underutilized. In order to get maximum production of their logs, most growers use a method called shocking to induce fruiting with WR and WW; however, research has shown that shocking does not trigger fruiting in the CW strains; rather, CW strains respond to temperature fluctuations. Taking this into account, we’ve introduced a hybrid approach of growing CW shiitake, which combines outdoor and indoor cultivation techniques to best imitate that temperature fluctuation. Growing CW shiitake using a hybrid approach can be the best choice for small-scale growers who wish to extend their growing season into the winter months, thus opening new market opportunities. By conducting interviews with shiitake growers in similar climates and compiling and analyzing literature from other professionals, we have gathered data on log harvesting, laying yard conditions, moisture management, and lighting conditions and developed a best management practices guide for small-scale shiitake grower/woodlot owners in a northern Adirondack climate. Ultimately, growers could diversify their sources of income, provide incentive to manage their woodlots and most importantly learn how to effectively utilize CW strains through the winter months.

Interactive Electronic Education at the Paul Smith’s Visitor Interpretive Center

Tue, 05/05/2015 - 16:30
Abstract: The use of electronics in an educational setting is a debated topic, but certain kinds of programs are becoming more prominent. The purpose of this study is to examine how interactive electronic environmental education programs are used to facilitate environmental education, and attempting to determine whether or not the Paul Smith’s College Visitor Interpretive Center (VIC) could make use of them. Through interviews with key members of the Paul Smith’s College and the VIC as well as surveying the general public of both communities it was determined that these forms of educational programs were not in high demand by the users of the VIC, but electronic recreation tools were.

Management of the Invasive Species; a recommendation to the Paul Smith's College VIC

Wed, 05/06/2015 - 08:10
Abstract: This research looks at invasive species that are harming the Adirondack region. By examining both invasive species on land and water we can make connections to what the problematic issues are. By understanding the species, information can be gathered to educate the public on what to look for and how to prevent the species from spreading. Paul Smith’s College VIC is looking for new ideas to incorporate for both the campus and local community. The focus of this project is to look at what the VIC has done in the past, present and future in terms of education and programs. Creating a new program and addressing an environmental issue are two key components that we hope to make the VIC a stronger addition to the area.

The Potential Distribution of Invasive Species Parallel to Climate Change at the Paul Smiths College Visitor Interpretive Center

Wed, 05/06/2015 - 13:17
Abstract: Human civilizations have been contributing to global climate change for as long as they have been altering the landscape. Whether it be from deforestation, to the release of carbon dioxide, we have been continually causing a greenhouse effect in the atmosphere. Due to warming temperatures, climate conditions have become more variable in the recent decades. A change of variability in the climate, also means a change in species distribution. As temperatures fluctuate in the Adirondack Park we may begin to see an increase in invasive plant species. Many invasive plant species have the ability to outperform native plants in regards to changing climates and eventually take over an area. The purpose of this study is to determine which plant species are most likely to make their way into the Paul Smiths College Visitor Interpretive Center, parallel to climate change, and what may be done to prevent or mitigate this new, potential alteration to the landscape.

Presence and Abundance of Microplastics within Flowing Waters of Private, Wilderness, and Other Forest Preserve Lands of the Northern Adirondack Park

Mon, 04/28/2014 - 16:26
Abstract: Microplastic sampling was conducted at thirteen locations throughout the water bodies of the Northern Adirondack Region. Plastics were found at all thirteen sites, which were categorized by the impact level of human development. Any particle less than 5mm can be defined as a microplastic particle. Microscopic plastics can be found in a variety of chemical cleaners, clothing fabrics, and concrete solutions. Storm water drainage systems and wastewater treatment plants are confirmed sources of microplastic pollution, which carry pollutants into our rivers, lakes, and streams. Ingestion of microplastic particles can lead to many distinctive threats, including biological and physical abnormalities, while possibly leading to bioaccumulation and biomagnification throughout the food web. Future practices for management and prevention of microplastic pollutants in the Adirondacks is critical for environmental protection, while also portraying a worldly view of an overlooked human induced issue.
