Examining The Effectiveness Of Ecotourism As A Funding Source For Protected Area Management In Guyana, Jordan S. Flagel

Masters Theses, 2010-2019

Protected areas in tropical rainforests serve many important ecosystem services, including carbon sequestration. These areas are often in need of donor or grant funding to operate as governments in tropical forested countries are not always able to provide adequate funds for protection. This paper focuses on the Iwokrama International Center for Rainforest Conservation and Development in the South American country of Guyana, which has had funding issues since the global economic crisis of 2008 and an accompanying shift in donor country financial priorities. Increasing the amount of sustainable ecotourism in the Iwokrama reserve was identified as a potential source for …

Landscape fires show large variability in the amount of biomass or fuel consumed per unit area burned. Fuel consumption (FC) depends on the biomass available to burn and the fraction of the biomass that is actually combusted, and can be combined with estimates of area burned to assess emissions. While burned area can be detected from space and estimates are becoming more reliable due to improved algorithms and sensors, FC is usually modeled or taken selectively from the literature. We compiled the peer-reviewed literature on FC for various biomes and fuel categories to understand FC and its variability better, and …

Michigan Tech Research Institute Publications

The presented study quantifies the proportion of stand-replacement fires in Russian forests through the integrated analysis of Landsat and Moderate Resolution Imaging Spectroradiometer (MODIS) data products. We employed 30 m Landsat Enhanced Thematic Mapper Plus derived tree canopy cover and decadal (2001–2012) forest cover loss (Hansen et al 2013 High-resolution global maps of 21st-century forest cover change Science 342 850–53) to identify forest extent and disturbance. These data were overlaid with 1 km MODIS active fire (earthdata.nasa.gov/data/near-real-time-data/firms) and 500 m regional burned area data (Loboda et al 2007 Regionally adaptable dNBR-based algorithm for burned area mapping from …

The Optimal Foraging Of Equus Burchelli At Enashiva Nature Refuge, Edward Haubenreiser

Independent Study Project (ISP) Collection

Within the country of Tanzania lies a vast ecosystem known as the Serengeti. This unique landscape, primarily of grasslands and woodlands, shapes the seasonal feeding habits of the abundant wildlife that call the area home. While these feeding habits on a large spatial scale are well understood, such behavior within a specie’s specific environment remains of interest. With the theory of optimal foraging in mind, which considers how animals should look for and select food (Green, 1990), I studied the foraging habits of resident Burchell’s zebra (Equus burchelli) by observing if they move and forage among distinct resource …

Information And Entropy Theory For The Sustainability Of Coupled Human And Natural Systems, Audrey L. Mayer, Richard P. Donovan, Christopher W. Pawlowski

College of Forest Resources and Environmental Science Publications

For coupled human and natural systems (CHANS), sustainability can be defined operationally as a feasible, desirable set of flows (material, currency, information, energy, individuals, etc.) that can be maintained despite internal changes and changes in the environment. Sustainable development can be defined as the process by which CHANS can be moved toward sustainability. Specific indicators that give insight into the structure and behavior of feedbacks in CHANS are of particular interest because they would aid in the sustainable management of these systems through an understanding of the structures that govern system behavior. However, the use of specific feedbacks as monitoring …

As carbon modeling tools become more comprehensive, spatial data are needed to improve quantitative maps of carbon emissions from fire. The Wildland Fire Emissions Information System (WFEIS) provides mapped estimates of carbon emissions from historical forest fires in the United States through a web browser. WFEIS improves access to data and provides a consistent approach to estimating emissions at landscape, regional, and continental scales. The system taps into data and tools developed by the U.S. Forest Service to describe fuels, fuel loadings, and fuel consumption and merges information from the U.S. Geological Survey (USGS) and National Aeronautics and Space Administration …

Predicted Effects Of Gypsy Moth Defoliation And Climate Change On Forest Carbon Dynamics In The New Jersey Pine Barrens, Alec M. Kretchun, Robert M. Scheller, Melissa S. Lucash, Kenneth L. Clark, John Hom, Steve Van Tuyl

Environmental Science and Management Faculty Publications and Presentations

Disturbance regimes within temperate forests can significantly impact carbon cycling. Additionally, projected climate change in combination with multiple, interacting disturbance effects may disrupt the capacity of forests to act as carbon sinks at large spatial and temporal scales. We used a spatially explicit forest succession and disturbance model, LANDIS-II, to model the effects of climate change, gypsy moth (Lymantria dispar L.) defoliation, and wildfire on the C dynamics of the forests of the New Jersey Pine Barrens over the next century. Climate scenarios were simulated using current climate conditions (baseline), as well as a high emissions scenario (HadCM3 A2 …

Use Of Unmanned Aerial Vehicles (Uav) For Urban Tree Inventories, Brian Ritter

All Theses

In contrast to standard aerial imagery, unmanned aerial systems (UAS) utilize recent technological advances to provide an affordable alternative for imagery acquisition. Increased value can be realized through clarity and detail providing higher resolution (2-5 cm) over traditional products. Many natural resource disciplines such as urban forestry will benefit from UAS. Tree inventories for risk assessment, biodiversity, planning, and design can be efficiently achieved with the UAS. Recent advances in photogrammetric processing have proved automated methods for three dimensional rendering of aerial imagery. Point clouds can be generated from images providing additional benefits. Association of spatial locational information within the …

Review: Pollination, Pollinated And Pollinators Interaction In Pakistan, Mohammad Irshad, Elizabeth Stephen

Journal of Bioresource Management

The agriculture sector is important in the overall economy and export earnings of Pakistan. Pollination is an essential ecosystem service that depends on symbiosis between species, the pollinated and the pollinator. Animal mediated pollination contributes to the sexual production of over 90% species of modern angiosperms. Effective pollination results in increased crop production, quality improvement and more seed production. Many fruits, vegetables, edible oil crops, stimulant crops and nuts are highly dependent on bee pollination. Worldwide value of pollinators is €153 billion (217 billion US dollars). The production value of pollinated dependent crop in Pakistan is quantified to be 1.59 …

"Nature Is Pushing One Way And People Are Pushing The Other": A Political Ecology Of Forest Transitions In Western Montgomery County, Pa, Megan Elizabeth Maccaroni

Environment and Sustainability Honors Papers

Forests in Southeastern Pennsylvania have been shaped by a number of anthropocentric factors over the past century, with many areas experiencing a recent trend towards forest recovery. Studies on forest dynamics have shown that most developed regions exhibit a forest transition, which begins when land is cleared for natural resource extraction (e.g., agriculture, forestry) during an early development stage. Then as a population grows and food production needs are met, rural peoples begin to migrate to the city, and a feeling of scarcity of trees develops that may lead to changes in land management attitudes, and many formerly deforested areas …

Salinity Risk Mapping For Assessing Carbon Farming Initiative Proposals: Decision Support And Data Requirements, Paul Raper, Peter Gardiner

Resource management technical reports

The Clean Energy Legislation passed by the Australian Parliament on 8 November 2011 links the carbon price to the Carbon Farming Initiative (CFI). Under the Carbon Credits (Carbon Farming Initiative) Act 2011 (the Act), proponents need to consider regional natural resource management (NRM) plans to ensure that tree plantings for carbon bio-sequestration maximise environmental benefits and avoid unintended adverse effects on biodiversity, water and agricultural production systems.

The Effectiveness Of Forest Collaborative Groups At Reducing The Likelihood Of Project Appeals And Objections In Eastern Oregon, Brent M. Summers

Environmental Science and Management Professional Master's Project Reports

Collaborative planning has been used as a tool to address wicked natural resource conflicts and engage those affected by federal land management agency decisions. The United States Forest Service (USFS) is mandated by law to involve the public on project-level planning. In Oregon, Forest Collaborative Groups have been engaging with the USFS to involve stakeholders who are concerned with the activities on National Forests. It is widely believed that these groups are reducing project-level appeals and objections (appeals); however, there is no empirical evidence to validate these beliefs. National Environmental Protect Act (NEPA) document data were collected from the USFS …

Trail Degradation In Parque Internacional La Amistad: An Intersection Of Design, Management And Use, Jordan Stark

Independent Study Project (ISP) Collection

National parks are created and used for a variety of purposes but are primarily important for the conservation of natural resources and use by visitors. While park use is meant to be non-destructive, human interaction causes changes in ecosystems, leading to conflicts between these goals. Here, I examine the causes of trail degradation and impacts on surrounding forests in Parque Internacional la Amistad (PILA), Panama. This park is a world heritage site with the primary goal of preserving some of the world’s most diverse ecosystems including rare and endangered species. However, the park entrance in Las Nubes, Cerro Punta receives …

Forest - Atmosphere Interaction At Howland Forest, David Dail

University of Maine Office of Research Administration: Grant Reports

The overall goal of the proposed work is to understand the various (and interacting) impacts of a changing climate on carbon cycling at the Howland AmeriFlux site, representative of an important component of the North American boreal forest. Our focus is on quantitatively partitioning respiration into aboveground and belowground processes and into autotrophic and heterotrophic processes to better constrain carbon cycle models. Whole-ecosystem flux measurements generally do a poor job of separating photosynthetic uptake from respiration and cannot constrain (or assign) respiration to the different sources within an ecosystem. This partitioning is difficult, but we will take advantage of new …

Perfumed The Axe That Laid It Low: The Endangerment Of Sandalwood In Southern India, Ezra Rashkow

Department of History Faculty Scholarship and Creative Works

Between 1950 and 1970, on average over 480,000 Indian sandalwood (Santalum album) trees were harvested annually in the state of Karnataka in southern India. Then, in 1974, it was suddenly discovered that there were only approximately 350,000 standing trees left in the entire state. Overnight, India’s sandalwood industry ground to a halt. The species was on the brink of extinction. Harvesting and trade in Indian sandalwood, long considered the most precious wood in the world, was ineffectively banned. Smugglers could now make more money by felling sandal trees than by poaching elephants for ivory. This article uses the history of …

Climate Change Effects On Northern Great Lake (Usa) Forests: A Case For Preserving Diversity, Matthew Joshua Duveneck, Robert M. Scheller, Mark A. White, Stephen D. Handler, Catherine Ravenscroft

Environmental Science and Management Faculty Publications and Presentations

Under business as usual (BAU) management, stresses posed by climate change may exceed the ability of Great Lake forests to adapt. Temperature and precipitation projections in the Great Lakes region are expected to change forest tree species composition and productivity. It is unknown how a change in productivity and/or tree species diversity due to climate change will affect the relationship between diversity and productivity. We assessed how forests in two landscapes (i.e., northern lower Michigan and northeastern Minnesota, USA) would respond to climate change and explored the diversityproductivity relationship under climate change. In addition, we explored how tree species diversity …

Managing For Resistance And Resilience Of Northern Great Lakes Forests To The Effects Of Climate Change, Matthew Joshua Duveneck

Dissertations and Theses

Climate change is expected to drastically change the environmental conditions which forests depend. Lags in tree species movements will likely be outpaced by a more rapidly changing climate. This may result in species extirpation, a change in forest structure, and a decline in resistance and resilience (i.e., the ability to persist and recover from external perturbations, respectively). In the northern Great Lakes region of North America, an ecotone exists along the boreal-temperate transition zone where large changes in species composition exist across a climate gradient. Increasing temperatures are observed in the more southern landscapes. As climate change is expected to …
