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.

The Effects on Soil Caused by Garlic Mustard (Alliaria petiolata) in a Northern Hardwood Forest in the Northern Adirondack Mountains

Mon, 12/02/2013 - 10:54
Abstract: Plant invasions are thought to be among the worst causes of biological extinction and biodiversity loss in the modern world. With the United States spending upward of thirty four million dollars a year in attempts to control and repair the damages caused by invasive plants, not only are we feeling the biological effects, but we financially cannot afford to keep combating these invasive species (Barto and Cipollini, 2009). Garlic mustard (Alliaria petiolata) can invade multiple types of sites whether the soil is sandy or if a site has been disturbed. This invasive species will take over the understory and alter soil chemistry (Morris, McClain, Anderson and McConnaughay, 2012). This study aimed to look at how garlic mustard is affecting soils in the northern Adirondack Mountains in New York State. Although currently scattered and not very prevalent, there have already been changes to the soil chemistry. This study was conducted by setting up multiple plots within areas where garlic mustard was present and gathering soil to be used to test for nutrient values. It was found in this study that calcium, phosphorous, magnesium, potassium, sodium, aluminum and soil pH values changed due to the presence of garlic mustard.

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.

Draft Horse Sustainability Presentations: The effectiveness of presentations on draft animal power at the Adirondack Rural Skills and Homesteading Festival

Fri, 12/06/2013 - 12:53
Abstract: Paul Smith’s College has been putting on draft horse presentations for the public for many years but until now it was unknown how effective these were in education of the audience in topics of the interest. During the 2013 Adirondack Rural Skills and Homesteading Festival, a series of demonstrations and presentations were conducted for the public. Surveys of those in attendance have now given us information on how far people are traveling, what their prior experience is, what they want to learn, and how they want to learn it. From this information we wish to gauge attendees’ response to draft animals and their uses.

Current State of the Black Ash Stand on Heaven Hill

Fri, 12/06/2013 - 01:06
Abstract: This study was conducted to assess the health and current state of the rare black ash (Fraxinus nigra) tree species on Heaven Hill property located in Lake Placid, New York. Little is known about black ash trees ecologically, it is mainly known solely for its cultural significance in basket making by the indigenous. Therefore, to learn more about the intricacies of black ash twenty fixed area plots were used to characterize the overstory in the 4 acre black ash stand. Diameter at Breast Height (DBH), crown class, crown condition, bark depth, and basket quality were measured. One black ash tree and one tree of another species were cored in each plot to analyze annual growth rings. Age of black ash trees was derived from the rings along with average ring growth per decade. Using the computer program, NED-2, basal area per acre (sq. ft) and stems per acre were calculated for the black stand. There was found to be a drop in stems per acre and basal area per acre after the seven inch diameter is met. Poor crown condition was found to be very low in black ash trees and even lower with an increase in DBH; 0% of the black ash trees between 11.5” and 17.5” DBH had Poor crown condition. Basket quality was assessed for each black ash tree and was based solely on physical features observed in the field. Basket quality for the stand was nine percent which represents the range in DBH classes from 5” to 15”. Only sixteen black ash trees were found to be potential basket quality trees.

Developing a Log Rule for Portable Sawmill Operators in Vermont

Fri, 04/26/2013 - 10:30
Abstract: Since the beginning of the 19th century, American lumbermen have been vexed by one of the unique questions of their trade; how do you estimate the yield of squared lumber to be cut from a round log? Since 1825, answers to this question have come in the form of log rules; a table or formula that estimates the yield of logs. These tables are in no way universal, and in some cases are crudely inaccurate. The shortcomings of these log rules have manifest differently in the various geographic locales and industry sectors where they are used. This study sought to identify such shortcomings as they pertain to a specific group of lumbermen; portable sawmill operators. These sawyers utilize modern bandsaw technology and have unique business practices, yet they estimate outputs based on century old log rules created for traditional sawmills. Through the use of semi-structured open ended interviews, technical and socioeconomic information was gathered from 7 sawyers in Vermont. Among other concerns, five of the sawyers expressed the need for a better way to estimate log yield. Based on their collective suggestions and technical approaches, a new log rule was created here to address sawyers’ needs.

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.

Distribution of Native & Non-native Ground Flora in Upstate New York in Relation to Nearby Forest Roads

Fri, 12/07/2012 - 17:26
Abstract: Plant distribution and diversity are affected by disturbances in forested landscapes. Disturbances such as forest roads including skid trails and haul roads are among those which affect plants. The introduction and spread of invasive species is a big concern with these types of roads because of the damage these species cause to the ecosystem. The goal of this study is to determine the effect these forest roads have on distribution and diversity of plants relative to the distance from the road. I wanted to find out how non-native and invasive species were distributed, as well as native protected species. Transects in two separate regions were set up perpendicular to the roads at the sites chosen, and each transect contained 16 – 1m x 1m plots in which all plants were surveyed. This study showed that distance away from forest roads does not appear to significantly affect the number of plant species, distribution of native or non-native plants, or distribution of protected species in New York. Based on the findings in this study, forest managers may not need to be overly concerned with the effects of forest roads on plant populations, but they should consider management of invasive species since Japanese barberry (Berberis thunbergii) was found well beyond the disturbed area in this study. Since it was found near the forest interior, it may be causing damage to the ecosystem.

Evaluation of Current Old Growth Classification System Applied to Northern Hardwood Forests of Western New York State

Fri, 12/07/2012 - 17:08
Abstract: A study of four old growth stands in Western New York was conducted to document the ecological complexities and characteristics of these isolated pockets of protected forests. These stands were compared to stands in a study, Selected Nova Scotia old-growth forests: Age, ecology, structure, scoring (Stewart et.al, 2003). Using techniques and sampling of Stewart et al., data included estimated age structure, species composition, basal area, density, coarse woody debris, volumes, heights, and snags. All of the stands were uneven-aged, as were the stands in the comparison study. All stands displayed low varying basal area ranges and lower stand density than those stands in Stewart et al. The comparison study had basal areas ranging from 32.5 to 55.5 m^2/ha, but the collected basal area of this study ranged from 14.5 to 29 m^2/ha. Volumes of dead wood ranged from 2 to 60 m^2/ha, which again was significantly less than dead wood volumes in Stewart et al. Most of the dead wood volume was derived from coarse woody debris, with few snags throughout the stands. Six attributes were rated on a 100 point system according to age, primal value, diameters, lengths of dead wood, canopy structure and understory structure. The scores of this study ranged from 52 to 70, which were significantly less than the scores in the comparison study. The Nova Scotia stands were dominated by softwood species and were larger in acreage. The western New York stands were dominated mostly by hardwood species and were smaller in acreage. Due to these differences, the western New York stands fell short of the Nova Scotia stands in two important criteria: ‘Primal Forest Value’ and ‘Bole Length of Snags and CWD.’ The protocols of Stewart et al. were generally adequate for evaluating the old growth characteristics. However, this study suggests that some of the criteria could be adapted to capture characteristics found in smaller, isolated pockets of hardwood dominated old growth forests.
