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.

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.
