Book Description
Explores how the management of wetlands can influence carbon storage and fluxes. Wetlands are vital natural assets, including their ability to take-up atmospheric carbon and restrict subsequent carbon loss to facilitate long-term storage. They can be deliberately managed to provide a natural solution to mitigate climate change, as well as to help offset direct losses of wetlands from various land-use changes and natural drivers. Wetland Carbon and Environmental Management presents a collection of wetland research studies from around the world to demonstrate how environmental management can improve carbon sequestration while enhancing wetland health and function. Volume highlights include: Overview of carbon storage in the landscape Introduction to wetland management practices Comparisons of natural, managed, and converted wetlands Impact of wetland management on carbon storage or loss Techniques for scientific assessment of wetland carbon processes Case studies covering tropical, coastal, inland, and northern wetlands Primer for carbon offset trading programs and how wetlands might contribute The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity.Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

Book Description
It has been acknowledged that conservation planners miss out on great opportunities to achieve more efficient objectives when not integrating rigorous economic analysis in their modeling. This thesis presents economic modeling and research methods that not only provide critical information for conservation planning, but also for conservation policy analysis. Using the Delta Agricultural Production (DAP) model, I simulate a spatially differentiated greenhouse gas offset market for wetlands on agricultural lands in the Sacramento-San Joaquin Delta in California, United States. I also derive a Delta wetland pseudo-supply function based on payments in addition to the simulated offset market. The DAP is a regional agricultural production and economic optimization model that simulates farmer's decisions based on actual observations in the Delta. Results reveal that current greenhouse gas offset prices are not high enough to incentivize farmers to convert any current crop acreage into wetlands, but additional payments will induce this conversion. These results can be used to identify the quantity, location, and costs of potential wetlands on agricultural landscapes in the Delta. In this thesis I also quantify the values of ecosystem services that Delta wetlands provide through nutrients reduction and recreation opportunities, by drawing on estimates from the published literature. The avoided treatment costs estimate of reducing nitrogen and phosphorus is $125 per acre and the recreational consumer's surplus is $113 per acre. Combined with average greenhouse gas sequestration values, a conservative and minimal ecosystem service value estimate for an acre of wetland in the Delta is around $450. These estimates, along with other services identified, are an innovative and essential tool for conservation policy development and benefit/cost analyses of public expenditures. My methods show that economic modeling and valuation techniques can play a vital and powerful role in informing conservation planning and policy decision-making. In addition, this thesis presents a transferable example that can be applied to other conservation habitat types and geographic locations using other economic modeling tools.

Book Description
Seasonally managed wetlands in the Grasslands Basin ofCalifornia's San Joaquin Valley provide food and shelter for migratorywildfowl during winter months and sport for waterfowl hunters during theannual duck season. Surface water supply to these wetland contain saltwhich, when drained to the San Joaquin River during the annual drawdownperiod, negatively impacts downstream agricultural riparian waterdiverters. Recent environmental regulation, limiting discharges salinityto the San Joaquin River and primarily targeting agricultural non-pointsources, now addresses return flows from seasonally managed wetlands. Real-time water quality management has been advocated as a means ofmatching wetland return flows to the assimilative capacity of the SanJoaquin River. Past attempts to build environmental monitoring anddecision support systems to implement this concept have failed forreasons that are discussed in this paper. These reasons are discussed inthe context of more general challenges facing the successfulimplementation of environmental monitoring, modelling and decisionsupport systems. The paper then provides details of a current researchand development project which will ultimately provide wetland managerswith the means of matching salt exports with the available assimilativecapacity of the San Joaquin River, when fully implemented. Manipulationof the traditional wetland drawdown comes at a potential cost to thesustainability of optimal wetland moist soil plant habitat in thesewetlands - hence the project provides appropriate data and a feedback andresponse mechanism for wetland managers to balance improvements to SanJoaquin River quality with internally-generated information on the healthof the wetland resource. The author concludes the paper by arguing thatthe architecture of the current project decision support system, whencoupled with recent advances in environmental data acquisition, dataprocessing and information dissemination technology, holds significantpromise to address some of the problems described earlier in the paperthat have limited past efforts to improve Basin water qualitymanagement.

Abstract: Loss of wetland habitat and their associated services and functions during the past century has been extensive. As a solution, managers have turned to restoration, but even regionally, researchers lack agreement on monitoring criteria and analytical methods for defining restoration success. This study investigated the recovery trajectory of two recently restored wetlands in southern California as compared to a reference site using univariate, multivariate and equivalence analyses. Important abiotic and biotic parameters in the two restored marshes, such as salinity and invertebrate abundance, were equal or higher than the reference marsh using traditional simple hypothesis-based statistics like ANOVAs, indicating potential restoration success after 4 years. However, invertebrate community composition remained significantly using multivariate analysis. Inequivalence tests (an interval-based approach with reversed null hypothesis) indicated fewer parameters achieved restoration success, representing a more conservative approach. Overall, this demonstrates the need for long-term comprehensive monitoring that includes novel approaches to statistical analysis.
