Habitat Associations And Occupancy Modeling Of Marsh Birds In The Hudson Valley Region Of Eastern New York, Lauren Jorgensen Jan 2012

Habitat Associations And Occupancy Modeling Of Marsh Birds In The Hudson Valley Region Of Eastern New York, Lauren Jorgensen

Legacy Theses & Dissertations (2009 - 2024)

Populations of many North American marsh birds have declined over the past few decades, a trend commensurate with declines in wetland habitat area. Substantial declines in populations of breeding marsh bird species in New York State are associated with declines in wetland habitat area due to urbanization. The objective of this study was to examine what habitat and landscape features increase the probability of occupancy for nine target marsh bird species in New York State. This research was conducted in the Hudson River Valley region of Eastern New York, a region which is characterized by varied topography and geology, a …


Economic Assessment Of Rapid Land-Building Technologies For Coastal Restoration, Hua Wang Jan 2012

Economic Assessment Of Rapid Land-Building Technologies For Coastal Restoration, Hua Wang

LSU Master's Theses

In the wake of recent hurricanes, coastal managers in Louisiana have begun integrating infrastructure protection and habitat restoration. Concurrent with this change, emphasis has been placed on marsh creation (MC) techniques that rely on mechanical dredges and sediment conveyance pipelines to rapidly build new land. The costs and benefits of this approach are increasingly compared to more natural and slower methods using fresh water diversions (FWD), yet such comparisons are not typically inclusive of time and risk considerations. Data for more than 300 coastal wetland restoration projects were evaluated for the statistical development of generic acreage trajectories and restoration cost …
