Vegetation of Lacassine National Wildlife Refuge, Louisiana-Recent plant communities with comparison to a three-decade-old survey
Shifts in plant community composition and structure can affect the quality of habitat for wildlife species. Lacassine National Wildlife Refuge in southwestern Louisiana was established in 1937 with a primary goal of providing habitat for wintering waterfowl species. A large freshwater impoundment constructed on the refuge to improve waterfowl habitat value was completed in 1943. About 10 years aft

Photographic images captured while sampling for bald eagles near the Davis Pond freshwater diversion structure in Barataria Bay, Louisiana (2009-10)
The implementation of freshwater diversions in large-scale coastal restoration schemes presents several scientific and management considerations. Large-scale environmental restructuring necessitates aquatic biomonitoring, and during such field studies, photographs that document animals and habitat may be captured. Among the biomonitoring studies performed in conjunction with the Davis Pond freshwa

The role of soil fertility in restoring Louisiana's coastal prairie
Studies have shown that soil nutrients, especially nitrogen (N), play an important role in the reestablishment of native prairie plant species. Soil N favors early succession species while long-lived native perennials compete favorably in N poor soils and numerous restoration studies have employed carbon additions in the form of sawdust and/or sucrose to immobilize soil nitrogen. However, this tec

Coastal Prairie Restoration Information System: Version 1 (Louisiana)
The Coastal Prairie Restoration Information System (CPR) is a Microsoft Access database that allows users to query and view data about Louisiana coastal prairie species. Less than 0.1% of Louisiana's coastal prairie vegetation remains in a relatively undisturbed condition. Encompassing as much as 1 million hectares of land, coastal prairie is a hybrid of coastal wetlands and tall grass prairie. Ov

Does species diversity limit productivity in natural grassland communities?
Theoretical analyses and experimental studies of synthesized assemblages indicate that under particular circumstances species diversity can enhance community productivity through niche complementarity. It remains unclear whether this process has important effects in mature natural ecosystems where competitive feedbacks and complex environmental influences affect diversity-productivity relationship

Effects of prescribed fire in the coastal prairies of Texas
Prescribed fire is widely applied for habitat management in coastal ecosystems. Fire management plans typically list a variety of objectives for prescribed burning, including succession management, promotion of native flora and fauna, providing habitat for species of importance, wildfire risk reduction (fuels management), as well as reduction and/or prevention of invasive species. In most cases, t

A Floristic Quality Assessment system for the coastal prairie of Louisiana
Evaluation systems to assess the biotic integrity of plant communities exist for some ecosystems, but not the increasingly rare coastal prairies of Louisiana. A list of plant species occurring in Louisiana's coastal prairie was created and coefficients of conservatism (C) were assigned for each species. A Floristic Quality Index (FQI), which is calculated using the C values provided by a panel of

Lost and found: Louisiana’s coastal prairies
It’s hard to fathom, but in just 250 years, some 2.5 million acres of coastal prairie that once blanketed in southwest Louisiana have dwindled to just 200 in scattered parcels.The journals of early settlers give us a peek at what it was like: “plentiful game,” “seemingly infinite range for livestock forage,” “long growing season.” As the human population grew, with its concomitant increase in trad
