Description:

Abstract:

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.

Purpose:

The overall goal of this project, and related previous ecosystem history projects, is to document the predrainage distribution of vegetation and reconstruct paleohydrology of marl prairies, marshes, and sloughs of south Florida, in response to client groups that have been tasked with setting performance measures and targets for these key wetland habitats.

The immediate goals of this project are to develop a spatially complete reconstruction of the vegetation and hydrologic history of Everglades marl prairie habitats, to determine the timing of initial marl accumulation, and to improve our understanding of the patterns and causes of historical vegetation change. These data will be critical to improve forecasts of marl prairie response to different restoration scenarios.

A number of specific "major unanswered questions" listed in the DOI Science Plan will be addressed by this research. These include the following:

Arthur R. Marshall Loxahatchee NWR Internal Canal Structures:

What hydrologic targets will restore the natural predrainage hydrology? What is the ecological response to hydrologic change?

Water Conservation Area 3 Decompartmentalization and Sheetflow Enhancement:

What were the physical and ecological conditions in the Greater Everglades prior to drainage and modification, including physical, chemical, and biological processes responsible for development and persistence of soils and geomorphological patterns in the historical Everglades landscape

Additional Water for Everglades National Park and Biscayne Bay Feasibility Study:

What were the physical and ecological conditions in Shark River and Taylor Sloughs and Biscayne Bay prior to drainage and modification, including historic hydrologic, geologic, ecological, and water quality conditions?

Landscape-Scale Modeling:

What are the physical conditions in the Greater Everglades prior to drainage and how will the existing conditions respond to water management?

Recovery of Vegetative Communities and Multiple Animal Species:

How do we optimize the benefits of restoration for protected avian species in South Florida while minimizing tradeoffs caused by conflicting habitat needs?

This study supports these CERP projects by 1) conducting research to reconstruct past vegetation and hydrology and understand relative impacts of natural climate variability and human alteration of hydrology on critical habitats; 2) determining the primary external drivers of habitat formation and degradation; 3) providing modelers with data on historic/predrainage conditions to validate model estimates of predrainage hydrology; and 4) providing a predrainage land-cover dataset for use in a range of climate and hydrologic models.

Process_Step:

Process_Description:

We collected a total of 70 sediment cores from 35 sites in six Cape Sable Seaside Sparrow (CSSS) subpopulations. We photographed, described, and sampled five cores from CSSS subpopulations B-F.

Process_Date: 2008

Process_Step:

Process_Description:

Pollen and charcoal analysis were completed on five marl prairie cores from five different CSSS subpopulations. Six additional cores were described, photographed, and sampled for future analyses.

Process_Date: 2009

Process_Step:

Process_Description:

Pollen, charcoal, and carbon isotope analysis were completed on six marl prairie cores selected in consultation with colleagues at Everglades National Park. Age models based on radiocarbon dates, short-lived radioisotopes (210Pb and 137Cs), and pollen biostratigraphy were generated for each core. Other previously collected cores will be described, photographed, and sectioned for future analyses. In FY11, field work was conducted in Everglades National Park for three purposes. A series of surface samples was collected along vegetation transects established by M. Ross to refine pollen-based interpretation of past vegetation in marl prairie habitats and Shark River Slough. Sediment cores were collected at sites on Cape Sable and on the southwest coast of the Florida peninsula in sites previously occupied by Cape Sable Seaside Sparrows. These cores will be used to determine vegetation and hydrologic characteristics associated with CSSS occupation and abandonment. Sediment cores also were collected at six additional sites in Taylor Slough and Shark River Slough. These sites are co-located with stream gages based on consultation with P. Conrads and F. Marshall for model calibration studies.
