The Climb Towards Conservation: Identifying And Mitigating The Effects Of Outdoor Rock Climbing On Surrounding Ecosystems In Colorado, Chloe Sommer 2019 University of Colorado, Boulder

The Climb Towards Conservation: Identifying And Mitigating The Effects Of Outdoor Rock Climbing On Surrounding Ecosystems In Colorado, Chloe Sommer

Undergraduate Honors Theses

Since the 1960s, rock climbing has become an increasingly important player in America’s recreation landscape. Today, rock climbing is a growing contributor to the nation’s $800+ billion-dollar outdoor recreation industry, and indoor and outdoor climbing are more popular than ever. Historically, rock climbers and other outdoor recreationalists have claimed a correlation between recreation and conservation of public lands. Ample evidence suggests, however, that rock climbing still causes an array of negative impacts to ecosystems. This is the first known study to analyze potential impacts of recreational outdoor rock climbing on a large scale with GIS techniques, overlaying geographic ...


Boulder At The (Tree) Top: Considerations For The Future Of Our Urban Canopy, Natalie Buchholz 2019 University of Colorado, Boulder

Boulder At The (Tree) Top: Considerations For The Future Of Our Urban Canopy, Natalie Buchholz

Undergraduate Honors Theses

This study investigates how canopy cover differs across land use types in six study areas in the City of Boulder, Colorado. Canopy cover can affect the area by buffering extreme weather and reducing heat island impact. Hypotheses state: 1) urban land use areas will have lower canopy cover and higher impermeable surfaces than other land uses; 2) nearby neighborhoods will have similar tree cover; 3) study areas that have high canopy cover receive disproportionately high benefits from increases in canopy cover; 4) all six study areas would benefit from large increases to canopy coverage. In this assessment six GIS surveys ...


Harvesting Forest Biomass In The Us Southern Rocky Mountains, Lucas Patrick Townsend 2019 University of Montana

Harvesting Forest Biomass In The Us Southern Rocky Mountains, Lucas Patrick Townsend

Graduate Student Theses, Dissertations, & Professional Papers

Ponderosa pine (Pinus ponderosa) and other mixed conifer forests of the United States southern Rocky Mountains (SRM) evolved under a low-severity, high-frequency fire regime. With the arrival of Euro-American colonists, fire was excluded from most forests, causing stands to grow dense and become prone to uncharacteristic high-severity crown fires. To combat wildfire threat, restoration treatments are frequently used to restore historic stand structure and function, effectively reducing high-severity fire risk. However, these treatments may be costly and little information is available regarding the forest operations used in the SRM. In this thesis, five forest operations were studied in 2017 to ...


The Impact Of Tree Planting Program Governance Structure On Tree Survivorship And Vigor: A Case Study Using The Massachusetts Greening The Gateway Cities Program, Nicholas A. Geron, John Rogan, Deborah Martin, Marc Healy 2019 Graduate School of Geography at Clark University

The Impact Of Tree Planting Program Governance Structure On Tree Survivorship And Vigor: A Case Study Using The Massachusetts Greening The Gateway Cities Program, Nicholas A. Geron, John Rogan, Deborah Martin, Marc Healy

Proceedings of the Fábos Conference on Landscape and Greenway Planning

Trees in urban neighborhoods benefit residents by reducing building energy costs, providing cleaner air, decreasing surface runoff, and improving quality of life. However, tree canopy cover is not evenly distributed across neighborhoods in many mid-sized American cities which leads to higher air and surface temperatures, and increased energy bills for residents who are the most economically vulnerable. The state of Massachusetts (USA) created the Greening the Gateway Cities (GGC) program to increase tree canopy cover by 10% in post-industrial, midsized cities with lower educational attainment and lower income than state averages. The study posed two questions: what is the governance ...


Application Of Short Tandem Target Mimic (Sttm) Technique For Functional Analysis Of Micro-Rna396 In Transgenic Poplar Trees, Surattana Boonsai 2019 Michigan Technological University

Application Of Short Tandem Target Mimic (Sttm) Technique For Functional Analysis Of Micro-Rna396 In Transgenic Poplar Trees, Surattana Boonsai

Dissertations, Master's Theses and Master's Reports

Short Tandem Target Mimic (STTM) is a commonly technique used for functional studies of a number of genes in several plant model systems. However, very little is known about application of STTM technique in tree species. In this study, STTM was applied to knock down microRNA396 (miR396) in transgenic poplar trees for the first time. STTM396 expression resulted in dramatic decrease in miR396 expression levels leading to taller plants with larger leaves and larger leaf cell size. Additionally, an expression analysis of growth regulating factor genes (GRFs) that are members of miR396 target gene family showed up-regulation of GRF07 gene ...


Community-Centered Sustainable Conservation And Ecotourism Planning In The Bossou Forest Reserve, Guinea, West Africa, DESTINA SAMANI 2019 University of Montana

Community-Centered Sustainable Conservation And Ecotourism Planning In The Bossou Forest Reserve, Guinea, West Africa, Destina Samani

Graduate Student Theses, Dissertations, & Professional Papers

Ecotourism management has evolved over the years towards responsible conservation of the natural environment, sustaining the well-being of local people, enriching personal experiences and increasing environmental awareness. The development of a forest reserve is characteristic of the management–visitor–host community interface and the attendant competing interests in the face of new challenges, ideas and theories. In particular, host community participation in the conservation of the forest space tends to breakdown under weak ecotourism management, partly evident by the imbalanced exploitation of ecosystem services resulting in wildlife and society’s inability to cope effectively with the changes (Walker et al ...

Role Of Disease & Insects In Aspen Ecology, John C. Guyon II 2019 Utah State University

Role Of Disease & Insects In Aspen Ecology, John C. Guyon Ii

Aspen Bibliography

Aspen is a keystone species in montane forests, and enhances a number of key resource values including wildlife habitat, water resources, and fire behavior. Recently, aspen forests have experienced episodes of dieback and decline across western North America (Worrall et al. 2010, Guyon and Hoffman 2011). A large proportion of the dieback and decline has been linked to drought stress or drought-prone locations (Hanna and Kulakowski 2012). However, insects and diseases are commonly found in declining aspen stands, leading to confusion about the role of insects and diseases in aspen ecology. Additionally, aspen has a reputation for being susceptible to ...


Guidelines For Aspen Restoration In Utah With Applicability To The Intermountain West, Stanley G. Kitchen, Patrick N. Behrens, Sherel K. Goodrich, Ashley Green, John Guyon, Mary O'Brien, David Tart 2019 Utah State University

Guidelines For Aspen Restoration In Utah With Applicability To The Intermountain West, Stanley G. Kitchen, Patrick N. Behrens, Sherel K. Goodrich, Ashley Green, John Guyon, Mary O'Brien, David Tart

Aspen Bibliography

As highly productive and biologically diverse communities, healthy quaking aspen (Populus tremuloides; hereafter aspen) forests provide a wide range of ecosystem services across western North America. Western aspen decline during the last century has been attributed to several causes and their interactions, including altered fire regimes, drought, excessive use by domestic and wild ungulates, and conifer encroachment. Today’s managers need science-based guidance to develop and implement strategies and practices to restore structure, processes, and resilience to the full range of aspen functional types across multiple spatial scales. In these guidelines, we detail a process for making step-by-step decisions about ...

Biodiversity Within Aspen Forests, Paul C. Rogers 2019 Utah State University

Biodiversity Within Aspen Forests, Paul C. Rogers

Aspen Bibliography

Aspen have long been known for supporting lush vegetation and rich wildlife habitat. These features, alongside brilliant green and gold seasonal coloration, accompany a broadly appreciated aesthetic for aspen forests by the public-at-large. However, in earlier times timber producers in many locales considered aspen to have low value and actively eliminated them. More recent research has pointed out that relative moisture held within aspen communities facilitates a wide array of species – collectively, biodiversity – compared to surrounding vegetation types. Aspen groves in the Intermountain West, for example, are known to be second only to riparian forests is supporting the greatest number ...


Predatory Hymenopteran Assemblages In Boreal Alaska: Associations With Forest Composition And Post-Fire Succession, Alexandria Wenninger, Teresa Hollingsworth, Diane Wagner 2019 Utah State University

Predatory Hymenopteran Assemblages In Boreal Alaska: Associations With Forest Composition And Post-Fire Succession, Alexandria Wenninger, Teresa Hollingsworth, Diane Wagner

Aspen Bibliography

Changes to the fire regime in boreal Alaska are shifting the ratio of coniferous to deciduous dominance on the landscape. The increase in aspen and birch may have important effects on predatory hymenopteran assemblages by providing a source of extrafloral nectar and increasing prey availability. Furthermore, fire-induced changes in successional age alter habitat structure and microclimate in ways that may favor ants. This study is the first to characterize the influence of fire-related vegetation changes on boreal predatory hymenopteran assemblages. We compare the abundance, species richness, and composition of predatory hymenopteran assemblages among forests at different stages of succession and ...
