Growth of Black Spruce and Tamarack in Response to Abiotic Variables

Tue, 05/03/2016 - 12:46
Abstract: The growth of black spruce (Picea mariana) and tamarack (Larix laricina) was examined in relation to the potential influences of pH, dissolved oxygen, conductivity, water temperature, proportion of canopy closure and depth to ground water in a northern Adirondack peatland ecosystem. 42 plots were constructed in a sphagnum dominated wetland and sampled for the above abiotic variables throughout the summer and fall of 2015. Heights, ages and periodic annual increment of 26 tamarack and 23 black spruce samples were determined in February and March of 2016. An age to height ratio and periodic annual increment for each species was then regressed against the above abiotic variable data in order to determine any influence of these data on growth rates of the conspecifics. Results show that depth to water table and increased exposure to light had a significantly positive relationship with the age to height ratio of tamarack. Periodic annual increment of tamarack had a significant positive relationship with decreasing light exposure. Black spruce’s age to height ratio had a significant positive relationship with dissolved oxygen (mg/L).

A Comparison Study of Adirondack Region Clearcutting Implementation to that of Paul Smith’s College VIC FERDA Plots

Mon, 05/02/2016 - 10:44
Abstract: The students of Paul Smith’s College have a unique opportunity to explore the parameters of silviculture and forestry practices. Gaining the base knowledge of silvicultural systems while also, properly implementing timber harvesting methods in order to achieve the specific goals and objectives of these systems is tremendously useful for implementation in future years. This study investigated the silvicultural prescriptions of the Forest Ecosystem Research and Demonstration Area (FERDA) plots on Paul Smith’s College lands, in Paul Smiths, New York. Comparing the inventory of the two clearcut sites upon these lands to that of other harvests within the Adirondack Park can supply further knowledge on what can be expected after a specific silvicultural system. Clearcutting has the greatest effect on forest succession by removing the forest cover and allowing light to reach what was once a shaded forest floor. Comparing experimental five acre clearcuts to that of larger commercial clearcuts in the same region can further our understanding of regeneration composition after such timber harvesting operations occur. The variance between the age of the FERDA plot harvests and the age of the harvests completed on Landvest timberlands resulted in varying data. However, if four to eight more years was given for pseudo FERDA plots to mature, it is believed that these harvests would be similar in composition and structure.

Mycoremediation Potential of Pleurotus ostreatus in Logging Operations

Mon, 05/02/2016 - 10:43
Abstract: The unintentional spillage of diesel and hydraulic fluid is an unfortunate part of forestry operations and the traditional cleanup methods can be costly. Many studies have shown that white rot fungi (WRF) are capable of breaking down a wide variety of environmental pollutants, including diesel fuel. The purpose of this study is to evaluate the ability of a WRF, Pluerotus ostreatus, to breakdown hydraulic fluid. Soil and sawdust were mixed at a 1:1 ratio and jars had, 0%, 3%, 5% and 10% of their volume added in hydraulic fluid. All jars were fully colonized within two weeks and after 30 days the concentration of residual hydrocarbon was analyzed with an extraction. The results showed that the maximum degradation of hydraulic fluid occurred at 5%. In addition sawdust spawn was dehydrated at different temperatures, in order to assess possible field application. The only dehydration test that grew was the air dried sample.

Silvicultural Analysis of Northern Hardwood Regeneration at the Paul Smith’s College FERDA Plots

Mon, 05/02/2016 - 10:20
Abstract: In the northeastern forests most regeneration comes from natural regeneration that occurs after a disturbance. The Forest Ecosystem Research Demonstration Area (FERDA) plots located on the Paul Smith’s College VIC in the Adirondack Park are set up as an experiment to test different harvest methods in northern hardwood forests and see the results of each. We analyzed tree and sapling size class inventory data from clearcut, single-tree selection, and control treatments to compare regeneration present 14 years after the first harvests occurred. The clearcut treatments were the only treatments analyzed where American beech (Fagus grandifolia) was not the most abundant tree regeneration present. Both single-tree selection and control treatments were dominated by American beech with few other species present. Our results suggest that creating larger canopy openings, may allow species other than American beech, such as red maple (Acer rubrum) and yellow birch (Betula alleghaniensis) to become the most abundant species present.

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.

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.

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.
