Coastal Wetland Dynamics Under Sea-Level Rise And Wetland Restoration In The Northern Gulf Of Mexico Using Bayesian Multilevel Models And A Web Tool, Tyler Hardy

Master's Theses

There is currently a lack of modeling framework to predict how relative sea-level rise (SLR), combined with restoration activities, affects landscapes of coastal wetlands with uncertainties accounted for at the entire northern Gulf of Mexico (NGOM). I developed such a modeling framework – Bayesian multi-level models to study the spatial pattern of wetland loss in the NGOM, driven by relative RSLR, vegetation productivity, tidal range, coastal slope, and wave height – all interacting with river-borne sediment availability, indicated by hydrological regimes. These interactions have not been comprehensively investigated before. I further modified this model to assess the efficacy of restoration …

Effects Of Sediment Removal Techniques On Avian Communities And Vegetational Attributes In Restored Prairie Pothole Wetlands, Alexander Galt

Master's Theses

With the loss and degradation of wetlands in some areas of the Prairie Pothole Region (PPR) reaching 80-90%, it is critical that resource managers ensure that the habitat that is put back on the landscape is as high quality as possible. Resource managers have been excavating sediment and topsoil, to promote the “hemi-marsh” condition, during the wetland restoration process in the PPR for over 20 years. I refer to the commonly held perception that the hemi-marsh condition supports the most diverse avian communities in small prairie pothole wetlands as the hemi-marsh condition hypothesis. The literature currently does not address the …

Mimicking Fire For Post-Mining Restoration Success, Katherine M. Wilkin

Master's Theses

This study is based at Rocky Canyon Quarry (RCQ), a 200-acre granite aggregate open-pit quarry with chaparral-dominated plant communities located in San Luis Obispo County, CA. At RCQ, the Surface Mining and Reclamation Act (SMARA) of 1975 was interpreted as restoring the landscape to native plant communities. Native plant community restoration projects have occurred there since 1993 through cooperation with California Polytechnic State University Biology Department in San Luis Obispo, CA. I evaluated past restoration at RCQ and researched new techniques to improve chaparral restoration based on the natural processes of fire.

Chaparral is an important fire-dominated plant community within …
