Post Wildfire Vegetation Response To The Wildland-Urban Interface: A Case Study Of The Station Fire, Angelo C. De Guzman, Raju Bista, Parveen K. Chhetri
Post Wildfire Vegetation Response To The Wildland-Urban Interface: A Case Study Of The Station Fire, Angelo C. De Guzman, Raju Bista, Parveen K. Chhetri
CSU Journal of Sustainability and Climate Change
In the past, wildfires served as a method for mother nature to promote biodiversity and to help maintain a functioning ecosystem. However, climate change alters the fire regime, significantly impacting vegetation recovery. Human disturbances and increased land use and land cover heighten vegetation disruption and abundance after a fire. Wildland-urban interface (WUI) – the region where the vegetation intermingles with the roads, houses, and human-made structures – threatens vegetation and the human population. Overall vegetation recovery after the Station Fire of 2009 spread through the San Gabriel Mountains, Los Angeles County was observed using Digital Elevation Model (DEM), Normalized Difference …
Snow-Albedo Feedback In Northern Alaska: How Vegetation Influences Snowmelt, Lucas C. Reckhaus
Snow-Albedo Feedback In Northern Alaska: How Vegetation Influences Snowmelt, Lucas C. Reckhaus
Theses and Dissertations
This paper investigates how the snow-albedo feedback mechanism of the arctic is changing in response to rising climate temperatures. Specifically, the interplay of vegetation and snowmelt, and how these two variables can be correlated. This has the potential to refine climate modelling of the spring transition season. Research was conducted at the ecoregion scale in northern Alaska from 2000 to 2020. Each ecoregion is defined by distinct topographic and ecological conditions, allowing for meaningful contrast between the patterns of spring albedo transition across surface conditions and vegetation types. The five most northerly ecoregions of Alaska are chosen as they encompass …
Vegetation Land Cover/Use Dynamics And Their Effects In Mbulu And Karatu Districts In The North-Eastern Highlands Of Tanzania, Leonia John Raphael
Vegetation Land Cover/Use Dynamics And Their Effects In Mbulu And Karatu Districts In The North-Eastern Highlands Of Tanzania, Leonia John Raphael
International Journal of Geospatial and Environmental Research
Vegetation Land Cover/Land Use dynamics (VLC/LU) are the result of complex and compound interactions between the human (cultural, socioeconomic, and political) and the physical environment at different spatial scales. The present study assesses the spatial distribution of VLC/LU dynamics from 1987 to 2015 in the North-Eastern highlands of Tanzania using both qualitative (in-depth interviews and focus group discussions) and quantitative techniques (spatio-temporal analysis through GIS). The qualitative approach was used to elicit information on the main drivers of VLC/LU changes by land users as transitions occurred with time. The spatio-temporal analysis was used to assess the systematic vegetation land losses, …

Effects Of Environmental Factors On The Abundance Of Blacklegged Ticks, Jasmine L. Miller, Roger A. Lebrun, Howard S. Ginsberg
Effects Of Environmental Factors On The Abundance Of Blacklegged Ticks, Jasmine L. Miller, Roger A. Lebrun, Howard S. Ginsberg
Senior Honors Projects
The nymphal stage of the blacklegged tick, Ixodes scapularis, is the major vector of Lyme disease, the most common vector-borne disease in North America. Tick abundance has generally been estimated using either flag/drag samples or samples from hosts. However, the biases of these sampling methods have not been adequately studied. We compared samples using both methods from sites in Massachusetts and Wisconsin. Tick abundance was compared with variables related to weather (temperature, relative humidity, and tick adverse moisture events), vegetation (canopy cover, tree density, shrub density, ground vegetation, and leaf litter cover), and host abundance (mice, small mammals, medium …

Measuring And Modeling Of Urban Growth And Its Impacts On Vegetation And Species Habitats In Greater Orlando, Florida, Sunhui Sim, Victor Mesev
Measuring And Modeling Of Urban Growth And Its Impacts On Vegetation And Species Habitats In Greater Orlando, Florida, Sunhui Sim, Victor Mesev
International Journal of Geospatial and Environmental Research
Urban growth is widely regarded as an important driver of environmental and social problems. It causes the loss of informal open space and wildlife habitats. Timely and accurate assessments of future urban growth scenarios and associated environmental impacts are crucial for urban planning, policy decision, and natural resource management. In this study, five distinct scenarios ("no constraints", "compact development", "transit-oriented development", "agriculture protection" and "environmental protection" scenarios) were tested on Greater Orlando, Florida, along with conservation objectives and projections for future land use/cover from development demands. The study examined the consequences of alternative scenarios of urban growth on potential habitat …

A High-Resolution Record Of Vegetation And Climate Through The Last Glacial Cycle From Caledonia Fen, Southeastern Highlands Of Australia, A Kershaw, G Mckenzie, N Porch, Richard Roberts, J Browne, H Heijnis, M Orr, Geraldine Jacobsen, P Newall
Richard G Roberts
A blocked tributary has provided a rare site of long-term sediment accumulation in montane southeastern Australia. This site has yielded a continuous, detailed pollen record through the last ca. 140 000 years and revealed marked vegetation and environmental changes at orbital to sub-millennial scales. Radiocarbon and optically stimulated luminescence (OSL, or optical) ages provide some chronological control for the last ca. 70 000 years. Most of the sediment is inorganic but with well preserved pollen that accumulated under unproductive and probably largely ice-covered lake conditions. The lake was surrounded by low-growing plants with an alpine character. Exceptions include three discrete …
Evaluating Drought In The United States Using The Emissivity Difference Vegetation Index, Hanisha Hirani
Evaluating Drought In The United States Using The Emissivity Difference Vegetation Index, Hanisha Hirani
Legacy Theses & Dissertations (2009 - 2024)
As monitoring vegetation and crops becomes increasingly important due to climate change, there arises the need for a monitoring scheme that places more weight on water availability as an indication of vegetation health and vitality. The Emissivity Difference Vegetation Index (EDVI) is the first step towards that type of monitoring scheme. With the potential for diurnal studies, there are applications towards agriculture monitoring, wildfire monitoring, and much more. EDVI is a synergetic product retrieved from microwave, visible, and infrared satellite measurements, as well as reanalysis. Since microwave measurements are more sensitive to vegetation water content, EDVI has the potential to …
Australia's Black Saturday Fires - Comparison Of Techniques For Estimating Emissions From Vegetation Fires, Clare Paton-Walsh, Louisa K. Emmons, Christine Wiedinmyer
Australia's Black Saturday Fires - Comparison Of Techniques For Estimating Emissions From Vegetation Fires, Clare Paton-Walsh, Louisa K. Emmons, Christine Wiedinmyer
Faculty of Science - Papers (Archive)
We present a comparison of techniques for estimating atmospheric emissions from fires using Australia's 2009 "Black Saturday" wildfires as a case study. Most of the fires started on Saturday the 7th of February 2009 (a date now known as "Black Saturday") and then spread rapidly, fanned by gale force winds, creating several firestorms and killing 173 people. The fires continued into early March, when rain and cooler conditions allowed the fires to be extinguished. In this study, we compare two new techniques (and one more established method) to estimate the total emissions of a number of atmospheric trace gases from …

Australian Backyard Gardens And The Journey Of Migration, Lesley M. Head, Pat Muir, E. Hampel
Australian Backyard Gardens And The Journey Of Migration, Lesley M. Head, Pat Muir, E. Hampel
Lesley Head
Gardens have been an important site of environmental engagement in Australia since the British colonization. They are places where immigrant people and plants carry on traditions from their homelands, and work out an accommodation with new social and biophysical environments. We examine the backyard gardens of three contemporary migrant groups in suburban Australia, Macedonian, Vietnamese and British-born, and a fourth group of first generation Australians with both parents born overseas. There is strong emphasis on the production of vegetables in Macedonian backyards, and herbs and fruit in Vietnamese backyards. British backyards were more diverse, some focusing on non-native ornamental flowers …

Functional Relationships Between Vegetation, Channel Morphology, And Flow Efficiency In An Alluvial (Anabranching) River, John D. Jansen, Gerald C. Nanson
Faculty of Science - Papers (Archive)
Water and sediment flux interactions are examined in Magela Creek, an alluvial (anabranching) sand bed river in the northern Australian tropics. Dense riparian vegetation stabilizes the channels and floodplains thereby preventing erosional instability at flow depths up to 6.2 times bankfull and discharges up to 15 times bankfull. Narrow anabranching channels characterize > 92% of the alluvial reach and transport bed load more efficiently than short reaches of wide single-channels, yet overall 29 +/- 12% of the bed load is sequestered and the average vertical accretion rate is 0.41 +/- 0.17 mm yr (1) along the 12 km study reach.

Impacts Of A Woody Invader Vary In Different Vegetation Communities, T J. Mason, K French
Faculty of Science - Papers (Archive)
The impact of an exotic species in natural systems may be dependent not only on invader attributes but also on characteristics of the invaded community. We examined impacts of the invader bitou bush, Chrysanthemoides monilifera ssp. rotundata , in fore and hind dune communities of coastal New South Wales, Australia. We compared invader impacts on vegetation structure, richness of both native and exotic growth forms and community variability in fore and hind dunes. We found that impacts of bitou invasion were context specific: in fore dune shrublands, functionally distinct graminoid, herb and climber rather than shrub growth forms had significantly …

The Vegetation Requirements Of Superb Fairy-Wrens (Malurus Cyaneus) In Non-Urban Edge And Urbanised Habitats, H Parsons, Kristine O. French, R E. Major
Faculty of Science - Papers (Archive)
Urbanisation has created an environment with a broad spectrum of habitats of differing quality for birds. Understanding habitat characteristics is necessary for effective conservation of species in urban environments. We investigated the vegetation requirements of a small, shrub-nesting, Australian bird, the Superb Fairy-wren (Malurus cyaneus), and the relative quality of urban habitats in the Illawarra region of New South Wales. Vegetation was assessed in three different habitats: suburban sites within Superb Fairy-wren territories (n = 20 sites), suburban sites where Fairy-wrens were absent (n = 20), and rural–woodland edge in which Fairy-wrens were present (n = 17). This third habitat …
