Abstracts from "Coastal Marsh Dieback in the Northern Gulf of Mexico: Extent, Causes, Consequences, and Remedies Abstracts from "Coastal Marsh Dieback in the Northern Gulf of Mexico: Extent, Causes, Consequences, and Remedies
In the spring of 2000, scientists discovered a new and unprecedented loss of salt marsh vegetation in coastal Louisiana and other areas along the northern coast of the Gulf of Mexico. This dieback of salt marsh vegetation, sometimes called the brown marsh phenomenon', primarily involved the rapid browning and dieback of smooth cordgrass (Spanina alterniflora). Coastal Louisiana has...

Manatees in the Gulf of Mexico Manatees in the Gulf of Mexico
The endangered Florida manatee (Trichechus manatus latirostris) inhabits rivers and estuaries along both coasts of Florida and, to a lesser extent, adjacent states (Figure 1). Since 1990, documented sightings of manatees outside of Florida have been increasing. This increase in sightings probably represents northward shifts in manatee distribution made possible by man-made sources of...

Pattern and process of land loss in the Mississippi Delta: A spatial and temporal analysis of wetland habitat change Pattern and process of land loss in the Mississippi Delta: A spatial and temporal analysis of wetland habitat change
An earlier investigation (Turner 1997) concluded that most of the coastal wetland loss in Louisiana was caused by the effects of canal dredging, that loss was near zero in the absence of canals, and that land loss had decreased to near zero by the late 1990s. This analysis was based on a 15-min quadrangle (approximately 68,000 ha) scale that is too large to isolate processes responsible...

Fire in eastern ecosystems Fire in eastern ecosystems
Prior to Euro-American settlement, fire was a ubiquitous force across most of the Eastern United States. Fire regimes spanned a time-scale from chronic to centuries. Fire severity varied from benign to extreme (fig. 1-2). Today, fire is still a major force on the landscape. In some ecosystems fire stabilizes succession at a particular sere, while in others, succession is set back to...

Disruption and restoration of en route habitat, a case study: The Chenier Plain Disruption and restoration of en route habitat, a case study: The Chenier Plain
Cheniers (relict beach ridges) and other habitats adjacent to ecological barriers may be critical linkages in the migratory pathways of long-distance migratory birds. It is important that these wooded habitats provide enough food and cover at the right time to support these birds’ requirements. To date, little attention has been given to the conservation of coastal woodlands, habitats in...

The hidden costs of coastal hazards: Implications for risk assessment and mitigation The hidden costs of coastal hazards: Implications for risk assessment and mitigation
Two-year study undertaken by the H. John Heinz III Center for Science, Economics and the Environment to develop new strategies to identify and reduce the costs of weather-related hazards associated with rapidly increasing coastal development activities.

Conveying multiple, complex themes and classes for natural resource assessments Conveying multiple, complex themes and classes for natural resource assessments
Two methods were used to convey the spatial association between a classified forested landscape, the distribution of a hurricane impact, and the subsequent recovery of the habitat from the storm. The first method used a constant hue matrix with varying intensity to visually represent combinations of impact and recovery magnitudes. The second combined two colors of constant hue to...
