   "abstract": "Studies have shown that soil nutrients, especially nitrogen (N), play an important role in the\u00a0reestablishment of native prairie plant species. Soil N favors early succession species while long-lived native\u00a0perennials compete favorably in N poor soils and numerous restoration studies have employed carbon additions\u00a0in the form of sawdust and/or sucrose to immobilize soil nitrogen. However, this technique poses financial\u00a0and logistical challenges when reconstructing coastal prairie in former agricultural fields. In this study the\u00a0germination and survival of native prairie species were studied along a nutrient gradient established in an old\u00a0rice field in Gueydan, Louisiana. Fifty plots, planted with seeds of 22 native prairie species, received one\u00a0of five treatments: a low or high rate of nitrogen, no addition, and a low or high rate of carbon (sawdust and\u00a0sucrose).\u00a0 Vegetation coverage by species was sampled every September from 2004 - 2007. Precipitation was\u00a0well below normal from 2003 to the middle of 2006 except for April - June 2004. Above ground productivity\u00a0showed a strong response to nitrogen levels as measured by the percentage of available sunlight reaching\u00a0the ground. Species richness increased with increasing fertility, but despite the increase in biomass as\u00a0fertility increased there was no statistical difference in species conservatism values with conservative species\u00a0germinating and surviving in all treatments. These results suggest that factors other than N may influence the\u00a0outcome of succession in coastal prairie. It is hypothesized that drought adapted prairie perennials are superior\u00a0competitors in heavy clay prairie soils when receiving low levels of precipitation.",
