Forest Management In The Context Of Global Change: Impacts Of Disturbance, Adaptive Management, And Invasive Species On Northeastern Forests, Jennifer Santoro
Forest Management In The Context Of Global Change: Impacts Of Disturbance, Adaptive Management, And Invasive Species On Northeastern Forests, Jennifer Santoro
Graduate College Dissertations and Theses
Climate change is predicted to have variable and uncertain effects on forested ecosystems globally. In the northeastern US, natural disturbances have historically been a central driver of forest successional dynamics, but as climate warming is projected to alter the frequency and severity of these events, post-disturbance management strategies to sustain biodiversity and ecosystem services must adaptively change to promote forest resilience. A suite of adaptive silvicultural actions has been proposed to promote forest resilience in the face of uncertainty, but due to the multi-decadal scale of forest management, initial field experiments are only beginning to show results. To address these …
Factors Affecting The Adoption Of Automated Wood Pellet Heating Systems In The Northeastern Us And Implications For The Transition To Renewable Energy, Laura Edling
Graduate College Dissertations and Theses
Public and private incentive programs have encouraged conversions to high efficiency, low emissions wood heating systems as a strategy to promote renewable energy and support local economies in the Northeastern US. Despite these efforts, the adoption of these systems remains slow. The study that is the subject of this dissertation examines several social, economic, policy and environmental factors that affect the decisions of individuals and small-scale institutions (local business and community facilities) to transition to automated wood pellet boilers and furnaces (AWPH) utilizing local fuel sources. Due to the complexity and risk associated with conversion, the transition to these systems …
Master’S Project: Vermont Town Forest Recreation Planning And Community Assistance Program: The Future Of Forest-Based Outdoor Recreation, Taylor M. Luneau
Master’S Project: Vermont Town Forest Recreation Planning And Community Assistance Program: The Future Of Forest-Based Outdoor Recreation, Taylor M. Luneau
Rubenstein School Masters Project Publications
The Vermont Town Forest Recreation Planning Community Assistance Program (VTFRP) was a comprehensive community planning process held in ten diverse towns across Vermont. Led by the Urban and Community Forestry Program and the SE Group, the VTFRP helped towns develop a vision for the future management of their forests through open house workshops, site visits, steering committee meetings, and community surveys. The process provided towns with a forest recreation planning toolkit and an individualized action-based forest stewardship and recreation plan. By analyzing data from the community surveys and open house activities across all ten towns, my project considered the recreation …
Lasting Legacies Of Hurricane, Harvesting, And Salvage Logging Disturbance On Succession And Structural Development In An Old-Growth Tsuga Canadensis-Pinus Strobus Forest, Emma Sass
Graduate College Dissertations and Theses
Disturbance events affect forest composition and structure across a range of spatial and temporal scales, and forest development may differ after natural, anthropogenic, or compound disturbances. Following large, natural disturbances, salvage logging is a common yet controversial management practice around the globe. While the short-term impacts of salvage logging have been studied in many systems, the long-term effects remain unclear. Further, while natural disturbances create many persistent and unique microsite conditions, little is known about the long-term influence of microsites on forest development. We capitalized on over eighty years of data on stand development following the 1938 hurricane in New …
Regeneration Responses To Management For Old-Growth Characteristics In Northern Hardwood-Conifer Forests, Aviva Joy Gottesman
Regeneration Responses To Management For Old-Growth Characteristics In Northern Hardwood-Conifer Forests, Aviva Joy Gottesman
Graduate College Dissertations and Theses
Silviculture practices interact with multiple sources of variability to influence regeneration trends in northern hardwood forests. There is uncertainty whether low-intensity selection harvesting techniques will result in desirable tree regeneration. Our research is part of a long-term study that tests the hypothesis that a silvicultural approach called "structural complexity enhancement" (SCE) can promote accelerated development of late-successional forest structure and functions. Our objective is to understand the regeneration dynamics following three uneven-aged forestry treatments modified to increase postharvest structural retention: single-tree selection, group selection, and SCE. In terms of regeneration densities and composition, how do light availability, competition, seedbad, and …
Long-Term Forest Carbon Storage And Structural Development As Influenced By Land-Use History And Reforestation Approach, Andrea Rose Urbano
Long-Term Forest Carbon Storage And Structural Development As Influenced By Land-Use History And Reforestation Approach, Andrea Rose Urbano
Graduate College Dissertations and Theses
Temperate forests are an important carbon sink, yet there is uncertainty regarding land-use history effects on biomass accumulation and carbon storage potential in secondary forests. Understanding long-term biomass dynamics is important for managing forests as carbon sinks and for co-benefits such as watershed protection and biodiversity. However there are many unanswered questions regarding these dynamics in northeastern U.S. forests: How have secondary forests of the U.S. Northeast recovered post nineteenth century agricultural abandonment? How has the region's extensive land-use history influenced long-term structural development and aboveground carbon storage? To answer these questions, we employed a longitudinal study based on twelve …
Lidar Remote Sensing Of Forest Canopy Structure: An Assessment Of The Accuracy Of Lidar And Its Relationship To Higher Trophic Levels, Christopher Felix Hansen
Lidar Remote Sensing Of Forest Canopy Structure: An Assessment Of The Accuracy Of Lidar And Its Relationship To Higher Trophic Levels, Christopher Felix Hansen
Graduate College Dissertations and Theses
Light detection and ranging (LiDAR) data can provide detailed information about three-dimensional forest horizontal and vertical structure that is important to forest productivity and wildlife habitat. Indeed, LiDAR data have been shown to provide accurate estimates to forest structural parameters and measures of higher trophic levels (e.g., avian abundance and diversity). However, links between forest structure and tree function have not been evaluated using LiDAR. This study was designed and scaled to assess the relationship of LiDAR to multiple aspects of forest structure and higher trophic levels (arthropod and bird populations), which included the ground-based collection of percent crown and …
Why I Love Grasshopper Sparrows, Michele Patenaude
Why I Love Grasshopper Sparrows, Michele Patenaude
UVM Libraries Conference Day
Since 2001, Michele (a library circulation supervisor in her day job) has conducted a summer breeding-bird survey of Grasshopper Sparrows at Camp Johnson in Colchester, VT. Named Grasshopper Sparrows because their breeding call sounds like a grasshopper, this little brown bird is endemic to certain types of scrubby grasslands which are becoming more scarce in the Northeast. The Grasshopper Sparrow is also declining and the species is not on the list of Vermont Endangered Birds. Come to this presentation and learn about the bird, how Michele surveys them, why they are endangered, and why Michele loves these quiet, little brown …
