Project Title: Landscape Pattern – Marl Prairies/Slough Gradients

Responses to this Request for Statements of Interest will be used to identify potential investigators for a project to be funded by the Engineering Research Development Center (ERDC) which provides information regarding changes in prairie and slough communities in response to restoration efforts under the Comprehensive Everglades Restoration Plan (CERP) program. Approximately $96,281 is expected to be available to support this project for one (1) year. Funding for efforts in future years may be available up to 4 years at $96,281/yr for a total of $481,405 over 5 years.


The Water Resources Development Act (WRDA) of 2000 authorized the Comprehensive Everglades Restoration Plan (CERP) as a framework for modifications and operational changes to the Central and Southern Florida Project needed to restore the south Florida ecosystem. Provisions within WRDA 2000 provided for specific authorization for an adaptive assessment and monitoring program. The CERP Monitoring and Assessment Plan (MAP) was developed as a framework for measuring and understanding system responses to CERP, determining how well CERP is meeting its goals and objectives, and indentifying opportunities for improving the performance of CERP where needed.

One key component of the MAP monitoring program is sampling of the marl prairie- slough gradient along Shark River Slough. In the past, water management-induced changes have altered the relative proportion of prairies and slough vegetation in the region, and future hydrologic restoration actions are expected to continue shifting the boundaries between prairie and slough vegetation communities. This project will draw upon prior research conducted in the area and continue to study how CERP restoration translates into impacts on prairie and slough landscapes.

Brief Description of Anticipated Work:

The purpose of this research is to monitor changes in vegetation along the prairie-slough gradient, in particular a number of transects previously established that extend across Shark River Slough and into the edges of the marl prairie on the eastern and/or western sides of the slough. Specifically, the objectives include:

  • Objective 1: Characterizing the composition, structure, and abundance of prairie and slough vegetation communities along the transects;
  • Objective 2: Identifying boundaries between differing vegetation types; and
  • Objective 3: Relating changes in vegetation structure to changes in hydrology resulting from CERP restoration projects.

Public Benefit:

This project will play a critical role in building the knowledge base for understanding the ecology of the marl prairie community and the ridge and slough community, as well as, the relationship between a variety of ecology stressors, such as hydrology and soil characteristics, and tree island attributes, such as species composition and species shifts. Marl prairie and ridge and slough are integral ecological communities of south Florida that provide a wide-range of ecosystem services. Understanding vegetation dynamics within the tree island landscape is critical to assess and predict the effects of hydrologic changes associated with ecosystem restoration and climate change which have potential impacts on the economy of South Florida, including tourism, recreational opportunities, and water management.

Vendor Requirements:

The Vendor must be a non-federal partner of the South Florida – Caribbean CESU Unit willing to accept the negotiated CESU indirect cost rate of 17.5%. Successful applicants should have expert knowledge of the Everglades ecosystem (in particular Shark River Slough) and a record that demonstrates research experience with marl prairie and slough vegetation communities. The candidates should have prior experience with sampling vegetation composition and structure at fixed locations, quantifying temporal changes in vegetation, and relating vegetation responses to hydrological changes. The candidates will be required to prepare a Statement of Work and Work Plan regarding the research to be conducted. The candidates will also be required to submit three (3) quarterly status reports, one (1) annual report each year, and one (1) final report for all years of the contract to provide updates on monitoring, data collection and analyses, and assessments regarding the impacts of CERP implementation on marl prairie-slough gradients.

Government Participation:

The USACE will participate in study site selections, design, and work plan development. USACE will participate in field data collection efforts as appropriate, will review quarterly status reports, and will provide input to data interpretation for final reports, as well as review annual and final reports. USACE will incorporate the data and analysis into a system-wide database that assesses and evaluates ecosystem restoration efforts in central and southern Florida. Scientific and technical information generated from the project will be utilized to evaluate project/restoration performance and system responses to be used in the development of assessment reports describing and interpreting those responses.
