Title: Terracing at Pierce Marsh in Galveston Bay 2001-2002
Short Name: Pierce Marsh Terracing 2001-2002

Abstract:

Marsh terracing is used to restore coastal wetlands by converting shallow nonvegetated bottom to intertidal marsh. Terraces are constructed from excavated bottom sediments, and are commonly arranged in a checkerboard pattern of square cells with open corners to form terrace fields. The project was located in shallow estuarine waters, and used bottom sediments or upland soils to construct intertidal areas planted with smooth cordgrass, Spartina alterniflora. We used a quantitative sampling device to compare nekton densities and biomass in habitat types of marsh terraces of three cell sizes at Pierce Marsh in Galveston Bay to a nearby reference marsh. Within terrace cells, density, biomass, and species richness were generally higher in marsh vegetation than over nonvegetated bottom. We also used Geographic Information System (GIS) and high-resolution aerial photography to classify areas into land (marsh vegetation) and water and applied fishery density models to assess fishery support. These models describe finescale distribution patterns for brown shrimp Farfantepenaeus aztecus, white shrimp Litopenaeus setiferus, and blue crab Callinectes sapidus across shallow estuarine habitat types (emergent marsh and shallow open water) of Galveston Bay. We show that populations of most fishery species increase as cell size decreases. However, as cell size decreases, the cost of terrace construction increases much faster than population size. Therefore, terrace fields constructed of medium or large cells would be more cost effective in providing fishery habitat than would terraces composed of small cells. Based on our modeling results, restored sites supported relatively high populations of fishery species compared to pre-restoration conditions. However, restoration sites did not support populations’ equivalent to a reference marsh system. Restoration projects should maximize the area of marsh vegetation and create a high degree of water-marsh interspersion to provide the most benefit for fishery species.

Purpose:

The purposes of this study were to evaluate marsh terracing as a method for restoring estuarine habitat and fishery production in Galveston Bay, and to test whether cell size affects the fishery value of habitat created by marsh terracing.

Data Quality

Accuracy:

Data were entered into spreadsheets and checked against the raw data sheet to avoid entry errors

Quality Control Procedures Employed:

Each sample was assigned a unique identification code. Field collected samples were tagged redundantly (e.g. one label inside of the collection vessel and a matching label attached to the outside of the vessel). The identifier and its associated information (e.g. date, location, habitat) was recorded on field data sheets. Once a sample arrived at the laboratory, the label remained with the sample throughout the various stages of sample processing. After data were entered into an Excel spreadsheet or similar database file, the information was printed out and compared against the field data sheets by two biologists. Corrections were made at this time and saved. The resultant electronic file was also sorted and examined by the Lab Supervisor or other project personnel in a variety of ways to look for outliers, missing data, and other potential errors.

Process Steps

Process Step 1

CC ID: 282842
Description:

After sample collection, field data were entered into an Excel spreadsheet or database file (DBF) using database manager software. A text file was created to describe these data and associated variables. Entered data were checked against the field sheets by two biologists to minimize entry errors. Samples were processed in the laboratory, sorted, specimens identified and measured, and information was entered into an Excel spreadsheet or DBF file. Files were printed out and compared against original data sheets by two biologists for data entry errors. Corrections were made at this time, the electronic file was saved, and a back-up copy made. Hard copies of the QCd files were printed and stored in the project folder along with the original field and laboratory data sheets. The electronic file was also sorted and examined by the Lab Supervisor or other project personnel in a variety of ways to look for outliers, missing data, and other potential errors. Verified data files were then saved electronically on the Galveston Laboratory server and backed-up as needed.
