Summary

Abstract

Continuing wetland loss in Galveston Bay, Texas (USA) has led to the development of various salt marsh restoration projects. These constructed wetlands often attempt to mimic natural marsh landscape characteristics within the region and incorporate marsh edge, because marsh edge appears important for fishery production. We estimated the value of shrimp production from nine of these constructed wetlands for comparison with project construction costs that ranged between 9,555 and 45,311 ha-1.

Description

Defining a project area, and therefore the size of a project, is important in obtaining funding and assessing project success and performance. The projects we analyzed were designed to incorporate marsh edge, based partly on studies showing elevated nekton densities both in the vegetation and open water adjacent to this edge. Therefore, proposed project areas should include both emergent vegetation and shallow water. Because the outer project boundaries affect area and construction cost calculations, we standardized the designation of these boundaries and defined the project area using a 25-m buffer around marsh vegetation (Fig. 2). Small amounts of water greater than 25 m from marsh that were within these outer boundaries (less than 2.4% of any project area) were included in the project area. We also provided calculations of construction costs in relation to strictly the area of emergent marsh.
