Weaver Lecture Series Presents Dr. David Fowler @ School of Forestry & Wildlife Sciences
Apr 11 @ 3:00 pm – 5:00 pm

The School of Forestry and Wildlife Sciences is proud to present the 2017 Weaver Lecture Series. The second lecture of the two-part series to be offered this year, will be given by Professor David Fowler, Environmental Physicist of the Natural Environment Research Council, Edinburgh, United Kingdom.

Professor Fowler’s talk, “Impacts of Human Activities on the Global Nitrogen Cycle Through the 21st Century,” will discuss the efficacy of the Earth’s ecosystems, atmosphere and oceans to globally cycle increased fixed nitrogen from human activity.

Professor Fowler trained in Environmental Physics at the University of Nottingham, obtaining a PhD in 1976 from research on the dry deposition of sulfur dioxide by micrometeorological methods. His research focuses on the surface – atmosphere exchange processes of trace gases and particulate matter and has been applied to ozone, acid deposition, the global biogeochemical cycle of nitrogen, emissions of greenhouse gases, atmospheric aerosols and effects of pollutants on vegetation.

Fowler’s work has been widely applied in the development of effects-based pollution control strategies in the United Kingdom and elsewhere in Europe. He was awarded an Honorary Professorship at the University of Nottingham in 1991, became a Fellow of the Royal Society of Edinburgh in 1999, and a Fellow of the Royal Society of London in 2002. In 2005, he was awarded a CBE or Commander of the Most Excellent Order of the British Empire for his research of atmospheric pollution.

The School of Forestry and Wildlife Sciences’ Weaver Lecture Series was established in May of 1996 through an endowment provided by Earl H. and Sandra H. Weaver. The objective of the Weaver Lecture Series is to bring experts in various research areas relevant to forestry and wildlife sciences to the Auburn University campus to enhance the School’s academic programs through public lectures and interaction with faculty and students.

The lecture is open to the public and will be held Tuesday, April 11, at 3:30 p.m., in the Forestry and Wildlife Sciences Building, 1101 Conference Room. A reception for Dr. Fowler will be held prior to the lecture at 3:00 p.m.  For details about the Weaver Lecture Series and to review research abstracts, visit http://wp.auburn.edu/sfws/weaver/.

Title: Interactive Effects of Climate Change and Grazing on Ecosystem Productivity and Greenhouse Gas Balance at Multiple Scales from Landscape to Global

Location: 3315 Dixon Executive Conference Room

Date: Monday, April 12, 2017

Time: 8:30 – 9:30 a.m.

Abstract:

At a global level, the results showed that livestock grazing and climate change reduced net primary productivity at the rate of 28.5 TgC/yr and 10 TgC/yr, respectively. Soil organic carbon, on the other hand, reduced at a rate of 242 TgC/yr in response to grazing and 42 TgC/yr in response to climate change.

The results also showed that methane (CH4) emission from the global ruminant livestock sector accounted for 47-54% of all non-CO2 GHG agricultural emissions. Likewise, nitrous oxide emission from the global grasslands increased significantly from 1.41 Tg N2O-N/yr in 1961 to 1.89 Tg N2O-N/yr in 2014. Managed pastures dominated N2O emission contributing to up to 68% of the total grassland emissions. Overall, the results of this study demonstrate that increasing livestock production and climate change have profound impacts on the environment and the climate system. In order to mitigate GHG emissions from the livestock sector, direct and indirect approaches that relies on animal (improving feed quality, feed additives, animal productivity) and land (grazing optimization, transition to extensive system) based mitigation approaches and policy (imposing tax on conventional ranching) efforts that promote sustainable intensification should be implemented.

Title: Coppicing Evaluation in the Southeast of the U.S. to Determine Harvesting Methods for Bioenergy Production

Location: 3315 Dixon Executive Conference Room

Date: Thursday, April 13, 2017

Time: 2:00 – 3:00 p.m.

Abstract:

Renewable fuels are being tested as an alternative for fossil fuels. For the Southeast of the U.S., the use of woody biomass has been proven to be an excellent source of renewable energy in terms of cost-benefit and availability. Short rotation woody crops (SRWC) are timber plantations with exclusive characteristics that greatly meet intensive wood demand due their fast growth and ability to coppice. Coppice allows trees to regenerate multiple stems from the stump after the original tree is harvested. There are still uncertainties related to the potential complications caused by the agglomeration of stems on mechanized harvesting. In this study we investigate the physical attributes of two SRWC species, two years after harvest. A logistic regression was fit in an attempt to predict the probability of a stump to regenerate more or less stems based on the damage caused on the stump during harvest and stump diameter. Additionally, we examined the effects on stem crowding and final yield caused by season of harvest. The species used on this experiment were Eucalypt (Eucalyptus urograndis) (Florida) and Cottonwood (Populus deltoides) (Arkansas). In both locations, the seedling trees were harvested in different seasons (summer and winter) in order to stablish the seasonal plots. Data collection took place six months, and two years after harvest to investigate biomass gain, stem crowding, and clump dimension of the coppiced trees. Results from both species showed that stump diameter is positively related with stem crowding. The eucalyptus trees showed that stem crowding was negatively affected by stump damage. Seasonality of harvesting did not affect stem crowding in both species. The shape and dispersion of the regenerated stems did not present significant evidence that would affect harvest operations with current technology. In all cases, approximately 1% of the trees exceeded the threshold that represents unfeasibility of harvesting. Higher yields of dry biomass were found in the winter plots of both species. At age two, the dominant stems were not yet strong enough to suppress the neighboring stems, therefore, the volume found per stump increased nearly linearly with the number of stems growing from it.

Title: Economic analysis of habitat conservation banking in the United States

Location: 3315 Dixon Executive Conference Room

Date: Friday, April 21, 2017

Time: 8:00 – 9:00 a.m.

Abstract:

The Endangered Species Act (ESA) is probably the most powerful environmental law ever enacted in the United States and is often portrayed as one of the most extreme forms of government intervention. Private landowners often avoid management activities that can potentially attract endangered species into their land and probably take actions to eliminate endangered species habitats. Several landowner incentive programs have been implemented by the U.S. Fish and Wildlife Service to encourage landowner to manage their land in ways that provide ecosystem services to promote the recovery of listed species.

Conservation banking offers financial incentives to landowners in exchange for managing land in a way that provides habitat for endangered species. This feature of the market-based approach is generating specific price signals for entrepreneurs to get involved in solving environmental issues. The United States pioneered conservation banking program and is recognized as a leader in implementing biodiversity offsets as a means to conserve endangered species. Few studies have evaluated the performance of conservation banking market. However, most of those studies were conducted a decade ago.

In the first chapter, we fill the gap by quantifying the number of total banks, conservation credit inventory, sales, and analyze the trends and the characteristics of conservation banks. As of December 2015, we find 137 conservation banks conserving some 153,000 acres of land. This number has increased to 180,298 acres recently. Nearly, 519,540 conservation credits were generated from 137 banks and some 71,365 credits were sold in last 21 years. About 66% of conservation credits were sold by private companies and credit price ranges between $1,500 and $198,560 per credits. This chapter concludes that conservation banking has become a business-based habitat planning system and that large urban areas tend to have the highest demand for conservation credits and are willing to pay the highest prices per credit.

The second chapter presents an econometric analysis of factors influencing demand and supply of the conservation credit market. The results reveal that demand and supply are inelastic to price, suggesting that conservation credit price changes are not likely to result in significant changes in the demand for credits. Inverse price and quantity relation shows the actual distribution of price in the market. Furthermore, the results suggest that the marginal production of conservation credit is likely to increase over time with more land area allocated for conservation bank and likely to decrease with increased in land value.

The third chapter uses hedonics to explores the relationship between credit prices and the characteristics of credits. This approach allows an implicit price to be estimated for each covariate. Private bank ownership, species types, the number of listed endangered species, and time factors were significant predictors of credit price. These results should be useful for landowners, bankers, and investors interested in enhancing the marketability of their land and understanding the effect of management actions.

Chapter four assesses the conservation banking project investment by examining the costs structure, revenue, and profitability of several conservation banks. We calculated the net present value of selected numbers of conservation bank located in California at the discount rates of 5.57%. Results show that the all eight selected conservation banks’ NPV appears to be positive. Our findings suggest that the investment in conservation banking is not only profitable but also yield high returns. Those landowners who may have discouraged because of lack of knowledge and data and from the fear that presence of endangered species habitat in their land would result in a regulatory compliance can be reassured from our finding that conservation banking can be perspective market for financial incentives.

Finally, we conclude that conservation banking market is dynamic and imperfect and an econometric model that incorporates either the dynamic or oligopolistic aspects of the conservation banking market, or both, seems to be a more promising prospect for future research.
