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.

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.

Downtown Saranac Lake Urban Forest Management Plan

Thu, 05/07/2015 - 16:47
Abstract: Trees and green spaces are important resources to any community. They are public spaces which provide havens of relaxation, play, and mental and physical stimulation. Trees and green spaces have been proven to have a positive impact on the mental and physical wellbeing of area residents. However, the care of these trees and green spaces is often overlooked or not planned for, leading to human/nature conflicts at a fine scale (local level). This is where arborists enter; arborists are individuals trained in the art of caring for trees, and are often involved in every stage of a tree’s life cycle, from planting to removal. But arborists are also teachers, acting as the intermediary between urban trees and the public and providing education to the people. The village of Saranac Lake, New York, is no different. The results of the data collected on Saranac Lake’s downtown street trees and parks were analyzed and compiled into a comprehensive urban tree management plan. A total of 236 trees and shrubs were inventoried and assessed for their health, overall condition, and pruning needs. Also included in the urban tree management plan are observations on the current state of the urban forest, recommendations for the mitigation and correction of any observable problems, and prevention and treatment courses of action for any future insect pests.

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.

A Forest Management Plan For Lynn Woods Reservation

Sun, 04/27/2014 - 18:49
Abstract: Lynn Woods Reservation located in Lynn, MA (42°29' N, 70°59’ W) is a 2,200 acre municipal park under the joint management of the Lynn Parks Department and the Lynn Water and Sewer Department. Since 1881, there has been little management on the lands of the reservation. This project developed a forest management plan for the Reservation. A forest inventory took place in January 2014 utilizing SilviaTerra’s Plothound data collection app. Data was then processed in NED-2 and ArcGIS to create final data used in the creation of this plan. The tract was divided into three compartments based on location and access. Multiple stands are inaccessible or do not contain merchantable timber but most of this tract is harvestable. Based on the data collected, suggested silvicultural prescriptions were developed along with other management suggestions for the tract. This plan was submitted to the park ranger, Dan Smalls, for review and final implementation.

A Genetic Comparison of Two Populations of American Beech (Fagus grandifolia) Impacted by the Invasive Disease Complex Causing Beech Bark Disease

Mon, 04/28/2014 - 23:35
Abstract: Many mature American beech trees have died due to beech bark disease throughout the northeastern United States. However, there are many pockets of beech trees throughout its native range that show resistance to the disease. This study will be focused on comparing specific genetic markers in a variety of American beech trees which have been categorized by the levels of severity of beech bark disease per individual tree. Leaf and bud samples were taken in October 2013 from 30 individual trees with varying degrees of disease severity. DNA will be purified from these soft tissue samples in order to use PCR and focus on 5 microsatellite locations for a comparison between all individuals being sampled. These loci will help to determine the genetic differences and similarities between American beech trees with and without signs of resistance to beech bark disease. The results of this study will set the stage for a landscape level study in the future, as well as further studies on finding genetic markers for resistance.

Differences in soil fertility along roadsides between state and locally managed roadways in Franklin County, New York

Thu, 05/08/2014 - 20:30
Abstract: Techniques for managing roadways often incorporate use of sodium chloride, or roadsalt. Use of this substance can vary greatly depending on whether state or local municipalities are prescribing management for particular roadways. Roadsalt has the potential to affect the chemical composition of roadside soils. This study sought examine relationships between winter management techniques and soil chemical properties as distance increased from roadsides. Transects were set up perpendicular to 5 roads managed by the State of New York, and 5 roads managed by towns in Franklin County, New York. 10 samples were removed from the soil surface at each transect, every two meters back from each roadside from 2 to 20 meters. pH, conductivity, abundances of Ca, Na, K, Mg, Cl, % Na on CEC, & % Ca on CEC were determined for each sample. Using ANOVA equations pH, % Na, and Cl concentration were found to have significant relationship with distance while %Na, % Ca, and Na concentration had significant relationships with regards to management. It was concluded that Na is displacing large amounts of Ca on exchange near state managed roads, decreasing soil fertility specifically in those areas. Results follow trends found in other studies that cite increasing concentrations of both Na and Cl on watershed scales.

Alternative Management Methods for Acid Deposition in Lakes

Fri, 04/26/2013 - 18:09
Abstract: Acid deposition has been causing the acidification of lakes in the Northeast United States for decades. The result is lake ecosystems with abnormally low pH that stresses the organisms that live there. Management plans in place in the Adirondack Park have been working to remediate acidified lakes for the past few decades. Limestone (CaCO3) has been the generally accepted method for managing these lakes, in an attempt restore the lakes pre-impacted conditions. The purpose of this study was to evaluate the effectiveness of liming in reversing the effects of acidification, and to identify effective alternatives. Five alternatives were tested against limestone: Sodium carbonate (Na2CO3), Sodium bicarbonate (NaHCO3), Sodium acetate (CH3COONa), Magnesium carbonate (MgCO3), and Potassium carbonate (K2CO3). Double End-Point Titration tests were performed on all of the compounds, using both distilled water and lake water, to determine the relative alkalinity of each compound. Alkalinity is the measure of the ability of a solution to neutralize acid, also known as its "buffering capacity." Lake water was used in the titration tests in an attempt to mimic in-situ testing. The results of the titrations showed limestone proving to be the most effective in the lake water tests, with Magnesium carbonate and Potassium carbonate ranked closely behind. While limestone has proven to be an effective management method, its reliability is dependent upon the characteristics of the lake catchment, making it important to continue to look for alternative solutions.

Determining Habitat Suitability for Ruffed Grouse (Bonasa umbellus) in Five Forest Harvest Method Plots on the Paul Smith’s Visitors Interpretation Center Land to Promote Long Term Suitable Habitat.

Sun, 04/28/2013 - 11:42
Abstract: Ruffed grouse (Bonansa umbellus) populations are in a steady decline due to the loss of early successional forests. Our study focused on the suitability of ruffed grouse habitat which is considered an area with adequate food and cover in. We used a habitat suitability index designed for ruffed grouse in Colorado that included average height of woody stems, percent conifers, density of mature yellow birch, and total equivalent stem density as the variables that indicate whether an area has suitable cover and food for ruffed grouse. Using the habitat suitability index we measured the vegetation in five forest harvest methods including: single tree selection, two-age cut, shelter-wood cut, clear-cut, and a control plot to determine if a habitat suitability index developed in Colorado can be used to assess habitat suitability for ruffed grouse in New York. These plots are located in the Adirondacks in Northern New York State at the Paul Smith’s College Visitors Interpretation Center (VIC). Our results suggested that 14 years after harvest a single tree selection harvest method has the highest overall habitat suitability (0.95) for ruffed grouse. This is different from other studies we found that indicated clear-cut was the most suitable forest harvest method for ruffed grouse. We also projected the change in habitat suitability for height of woody stems over time for the clear-cut based on the yearly growth rate of 0.656 feet. Based on our findings from the study we made recommendations to land owners and land managers to develop and promote short term and long term suitable habitat for ruffed grouse. These recommendations included using a variety of forestry practices that included: single tree selection, shelterwood, and clear-cut because ruffed grouse require a variety of different cover types and habitat over their lifetime.
