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.

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.

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.
