Site condition, structure, and growth of baldcypress along tidal/non-tidal salinity gradients Site condition, structure, and growth of baldcypress along tidal/non-tidal salinity gradients
This report documents changes in forest structure and growth potential of dominant trees in salt-impacted tidal and non-tidal baldcypress wetlands of the southeastern United States. We inventoried basal area and tree height, and monitored incremental growth (in basal area) of codominant baldcypress (Taxodium distichum) trees monthly, for over four years, to examine the inter...

Recent sedimentation patterns within the central Atchafalaya Basin, Louisiana Recent sedimentation patterns within the central Atchafalaya Basin, Louisiana
Sediment deposition and storage are important functions of forested bottomlands, yet documentation and interpretation of sedimentation processes in these systems remain incomplete. Our study was located in the central Atchafalaya Basin, Louisiana, a distributary of the Mississippi River and contains the largest contiguously forested riparian wetland in North America, which suffers from...

Wind damage and salinity effects of Hurricanes Katrina and Rita on coastal baldcypress forests of Louisiana Wind damage and salinity effects of Hurricanes Katrina and Rita on coastal baldcypress forests of Louisiana
The frequency of hurricane landfall in a given coastal stretch may play a more important role in the ecology of coastal forests than previously thought because of direct and indirect impacts of fallen trees and the introduction of salt water that lingers long after the storm passes. Findings show that surge events can inundate interior freshwater forests many miles from the coast and...

Interactive effects of substrate, hydroperiod, and nutrients on seedling growth of Salix nigra and Taxodium distichum Interactive effects of substrate, hydroperiod, and nutrients on seedling growth of Salix nigra and Taxodium distichum
The large river swamps of Louisiana have complex topography and hydrology, characterized by black willow (Salix nigra) dominance on accreting alluvial sediments and vast areas of baldcypress (Taxodium distichum) deepwater swamps with highly organic substrates. Seedling survival of these two wetland tree species is influenced by their growth rate in relation to the height and duration of...

Predicting coastal retreat in the Florida Big Bend region of the Gulf Coast under climate change induced sea-level rise Predicting coastal retreat in the Florida Big Bend region of the Gulf Coast under climate change induced sea-level rise
Many wildlife preserves and refuges in coastal areas of our nation are slowly being inundated by rising sea-level. Land elevation and tidal flooding are key factors controlling the extent and zonation of coastal habitats. Warming of our global environment threatens to speed the rate of sea-level rise and perhaps further amplify the detrimental effects of tropical storms, droughts, and...

History and ecology of mangroves in the Dry Tortugas History and ecology of mangroves in the Dry Tortugas
Dry Tortugas National Park, which includes Bush, Long, Loggerhead, Garden, and Bird Keys, is a cluster of islands and coral reefs approximately 112.9 km (70 miles) west of Key West, Florida (fig. 1). These islands were explored in 1513 by Ponce de León, who named them for the abundance of sea turtles, “tortugas,” and the lack of fresh water in the area. Historically, the Tortugas shoals...

A 7 year record of above-ground net primary production in a southeastern Mexican mangrove forest A 7 year record of above-ground net primary production in a southeastern Mexican mangrove forest
Spatial and temporal variations in net above-ground primary production (NPP) and litter turnover rate were studied, from 1987 to 1993, in a mangrove forest bordering Laguna de Terminos, Mexico. NPP, the sum of total litter fall and wood production, was measured over the entire study period in three zones in a basin forest: zone I, where Rhizophora mangle (red mangrove) occurs but...
