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.

Soil and Vegetation Characteristics of High Elevation Wetlands in the Adirondack Park

Mon, 12/03/2012 - 17:14
Abstract: Wetland ecosystems are finally being understood for their true importance. Wetlands in the past were misunderstood and thought to be disease carrying burdens on our way of life; however this mentality changed during the mid-19thcentury. These ecosystems are important for biodiversity and act as natural water purification systems. This study was undertaken to help understand, the high elevation wetland characteristics. Our goals were to analyze the soils and describe the vegetation in high elevation wetlands. The soil and vegetative surveys helped define the characteristics of these ecosystems and create a better understanding of them. The combination of vegetation species that are wetland indicators were found in each site, the soil pH, and nutrients show that each site had signs of being a wetland community.

The Effect of Temperature and pH on the Growth of Variable-leaf Milfoil (Myriophyllum heterophyllum)

Tue, 12/04/2012 - 18:03
Abstract: A fundamental part of invasion biology is the prediction of the potential spread of nonindigenous species (NIS). This is due to the negative ecological, economic and human-health effects that NIS may cause. Variable-leaf Milfoil (Myriophyllum heterophyllum), a highly invasive NIS to the Northeast, is native to southern U.S. states from Florida to New Mexico, and has since spread to North Dakota and southwestern Quebec without becoming invasive to those areas. Variable-leaf milfoil is invasive to the Adirondacks in northern New York State and is spreading at a rapid pace. This study questions whether temperature and pH have an effect on the growth of Variable-leaf milfoil. In this laboratory experiment, the growth of 80 Variable-leaf Milfoil fragments was examined in warm (33.1275°C) and cold (23.135°C) temperatures, combined with 10 pH treatments. Fragments showed increased growth in cold water when compared to the warm temperature treatment, and no relationship was shown between temperature and pH treatment in relation to growth.

A Land Management Plan for the Gottemoeller Family Farm

Thu, 12/06/2012 - 09:58
Abstract: Private landowners own property that is used for a variety of purposes. A management plan can help them realize their goals. This management plan focuses on two main goals. One is to maximize the sustainable out put of black walnut and other quality hardwoods. The other is creation of quail habitat to increase the carrying capacity of bobwhite quail on the farm. Using aerial photos and field visits, the property was divided into ten different management units. Some units have a forestry focus and others have a quail habitat focus or both. A Wildlife Habitat Appraisal Guide was used to evaluate the existing habitat and to identify which elements need to be improved. Peer reviewed research and agency technical expertise were used to identify which practices will improve the limiting elements for quail habitat. A Forest Plan developed by a professional forester with the Missouri Department of Conservation was incorporated into the farm Management Plan.

A MULTI-SCALE EVALUATION OF THE EFFECTS OF FOREST HARVESTING FOR WOODY BIOFUELS ON MAMMALIAN COMMUNITIES IN A NORTHERN HARDWOOD FOREST

Fri, 02/01/2013 - 16:19
Abstract: Forest harvesting and subsequent effects on forest structure have been shown to influence mammalian community assemblages and the abundance of individual species, however less attention has been paid to the implications of how harvested timber is used. This is particularly relevant in the Northern Forest, where a considerable portion of the forest harvesting is used to produce biofuels. Biofuels harvesting typically involves the process of whole-tree chipping which may lead to a dramatic reduction in the amount of woody material in the form of slash and coarse woody debris (CWD) left in harvested stands. The goal of our study was to assess the effects of biofuels harvesting on forest structure and subsequent effects on mammalian community structure and abundance. To address this goal, we focused on a ~35 Ha area of partially-harvested northern hardwood forest in the northern Adirondacks, New York. To sample mammals we used a combination of Sherman traps and track plates established at two scales across stands within this area. Our results showed that the response of small mammals to changes in forest structure is both species and scale specific. At the individual trap scale, CWD, slash, and understory cover were important drivers of the occurrence of individual species of small mammals. At the larger “grid” scale, small mammal relative abundance was driven by canopy cover and the density of woody stems. Our results indicate that the current harvesting practices used for biofuel production in the Adirondacks are unlikely to result in declines in abundance of common small mammal species. However, the retention of some slash post-harvest may be beneficial to some species, thus foresters may want to include slash retention when developing silvicultural prescriptions.

Managing for increased productivity and size of an American kestrel (Falco sparverius) population in northern New York

Mon, 05/07/2012 - 12:58
Abstract: American kestrel (Falco sparverius) populations have recently declined across most of the eastern states. As a result, managers and concerned citizens alike have installed nest boxes across large areas to increase productivity. Mr. Mark Manske has run one of these nest box programs in northern New York, across parts of St. Lawrence and Franklin counties, over the past ten years. Through the combination of his research and other long term management plans, the ideal future plan was developed. The focus of the new plan is to boost efficiency of resources, ease of expansion and sustain a steady or increasing population of kestrels. GIS software was used to analyze each nest boxes’ characteristics in order to develop a model that may predict areas of possible high productivity. Surveys and public outreach are emphasized to create a broader supporting base and possibly acquire future partners for land use, volunteers and advertising. The continued monitoring of the northern New York kestrel population will ensure the presence of this vital species for generations to come.
