We evaluated the influence of marsh terracing on waterbirds in Louisiana’s Chenier Plain. Terracing is a novel technique used to slow coastal marsh loss. Terracing increases marsh edge and is assumed to slow erosion, decrease pond depth, and encourage vegetation production. From April to September 2005, we monitored waterbirds in paired terraced and unterraced ponds in three sites dominated by Spartina patens...
Broadleaf marsh once covered much of the wetland landscape along the Kissimmee River in central Florida, USA, but is currently restricted to remnant portions of the channelized floodplain that have been subjected to much shallower depths. The initial phase of Kissimmee River restoration, which began in 1999, and a prior (1984–1990) demonstration project increased water depths in several relict broadleaf...
Tidal marsh monitoring and restoration can benefit from the union of fine-scale remote sensing products and field-based survey data via spatial predictive models. As part of an interdisciplinary wetland monitoring project in San Francisco Bay, we developed a suite of 1-m pixel-level spatial metrics describing patterns in marsh vegetation and geomorphology for six sites across a large salinity gradient...
Irrigated rice fields in southern Brazil remain without surface water for 2 years during the fallow phase. The present study tested the hypothesis that the hydrologic regime adopted in rice fields of southern Brazil does not compromise the viability of resting stages of aquatic invertebrates. Dry sediment samples were collected from 9 rice fields with different durations of the fallow phase: 20 days,...
Depressional wetlands may be restored passively by disrupting prior drainage to recover original hydrology and relying on natural revegetation. Restored hydrology selects for wetland vegetation; however, depression geomorphology constrains the achievable hydroperiod, and plant communities are influenced by hydroperiod and available species pools. Such constraints can complicate assessments of restoration...
