Impacts of Hydrologic and Climatic Change on Greater Everglades Marl Prairies, Marshes, and Sloughs

The initial objective of this project is reconstruction of marl prairie vegetation and hydroperiod for the last few centuries to evaluate impacts of climate variability and anthropogenic alteration of hydrology on this critical habitat. An additional objective of the project is refinement of down-core estimates of hydroperiod and stage by calibrating results from new and existing cores with nearby stream gage records.

本项目的初始目标为重建近数个世纪以来的泥灰岩草原（marl prairie）植被与水文周期（hydroperiod），以此评估气候变率以及水文系统的人为改造对这一关键生境造成的影响。本项目的另一目标为，通过将新获取与已有的岩芯分析结果与邻近河流测站（stream gage）的记录进行校准，优化岩芯剖面的水文周期与水位（stage）估算精度。
