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.

Predicting the amount of usable lumber contained in American beech (Fagus grandifolia) logs infected with beech bark disease based on exterior defects.

Wed, 12/02/2015 - 10:09
Abstract: Beech Bark disease has had many effects on the hardwood forests of the northeastern United States. Many studies have been done in regards to the changes caused by the disease affecting the ecology, species composition of the forest, abundance of American beech (Fagus grandifolia), and physiology of individual trees. However, American beech is a dense, strong species that machines and bends well, and has uses in the form of flooring, handles, and some furniture. This study examines how the severity of beech bark disease affects the amount of usable lumber that can be recovered from American beech sawlogs. To do this, American beech sawlogs with varying degrees of beech bark disease infection were harvested, bucked and scaled. These logs were rated according to their degree of beech bark disease infection based on exterior defects such as raised or sunken cankers, fissures and evidence of scale insect. These logs were then sawn into lumber form and rescaled to find a percentage of usable lumber that resulted from the gross scale taken prior to sawing. There was not a definitive relationship between degree of infection, and lumber yield. This study will be useful to the stakeholders of the lumber industry to aid in predicting whether or not a log infected with beech bark disease can be economically used for lumber.

Vermont Maple Forest Products LLC. Forest Management and Business Plan

Wed, 12/02/2015 - 17:52
Abstract: Maple syrup production is an extremely important aspect of the American economy in the northeast, generating around 132 million dollars in revenue annually across its U.S production range (United States Department of Agriculture, 2014). At the current rate of production U.S producers are presently only tapping 0.4% of the maples which may be available (Farrell & Chabot, 2012). Vermont has the greatest number of its trees tapped, with 2.94% of available trees currently in production. The low percentage of tappable maple trees in production has been seen as a short coming in the industry. However, this does create the possibility for entry into the industry. Vermont Maple Forest Products LLC is in current maple production and desires to produce on an industrial scale. Simon Boulet and Claude Deschenes (2005) found that the highest degrees of profit are generated when a producer is considered a medium(5,000-19,000 taps)-large (>19,000 taps) supplier. At this point costs per tap are reduced and sap yeilds increase. Vermont Maple Forest Products currently has the land available for potentially over 28,000 taps. To achieve this goal a business plan and forest management plan was developed and will be implemented across the tract with the goal of maple syrup production.

Investigating Amount of Sample Points Necessary for Accurate Topographic Representation of the Ground Truth

Wed, 04/29/2015 - 18:18
Abstract: Topographic or elevation data has many uses and applications especially when it is converted into a Digital Elevation Model (DEM). Such uses are erosion modeling, surface hydrology, watershed modelling geomorphology, land-sliding, agriculture and ecosystem modeling to list a few examples. This project intends to determine the amount of topographic data points that need to be collected in order to create an accurate model of the ground topography. To accomplish the objective, a topographic survey was conducted on a grid pattern, with a spacing of 7.5 feet between points regularly spaced over one acre. After the data were collected, varying percentages of the total amount of points collected were removed and the resulting digital elevation model (DEM) was compared to the ground truth DEM. When comparing accuracy of interpolated elevation across the entire DEM with a RMSE (root mean square error) it was found that using a subset of 25-30% of the entire data set were needed to create a model that did not significantly differ from the Ground Truth. The change in volume of the elevation surface compared to the Ground Truth results in a linear relationship, as more points are added the closed the change in volume is to zero. The P value derived from the T-test of the mean elevations of the trial DEM’s and the Ground truth, reflect the results from the change in volume, as more points are added the closer to the truth the DEM becomes.

Implementing an Educational Demonstration Forest with Working Elements of Silviculture, Wildlife, Recreation, and Water in Harrietstown, Adirondack, NY

Tue, 05/05/2015 - 11:15
Abstract: The project being conducted will provide rationale about the importance of working forestry, all while maintaining positive public sentiment within the forest products industry. The project will focus on public education and maintain water quality, wildlife habitat, and recreational opportunities. The public will see developed interpretive areas with signage at points of interest. The designated area is located near the Adirondack Regional Airport, Hunt Road and NYS Route 30, and is comprised of 226 acres. There are varying stands in the tract that range from pure softwood, hardwood and mixed wood stands. After the designated area was selected, a timber cruise was conducted along with note taking and visual analysis of how the area could entice public use and education. Once all the data was gathered, the conclusion drawn was throughout all different forests types in the tract, there were multiple educational opportunities pertaining to water quality and wildlife habitat through use of sustainable forestry methods. The significance of this project is to facilitate public education on how forestry can be sustainable and beneficial. This will be shown through workshops, kiosks, interpretive walks and a menagerie of other proposed ideas.
