Project Reports


GEMS Phase I Report: Oyster Reef Restoration

The GEMS (Gulf of Mexico Ecosystem Service Logic Models and Socio-Economic Indicators) team will develop ESLMs and metrics for a wide range of coastal restoration approaches over the course of the project. This report presents the results of the first phase of the GEMS project, which focused on oyster reef restoration. Please note: Some of the terminology and results in this report have since been updated. The Phase 2 report has updated this information.


GEMS-Phase-II-Report cover

GEMS Phase II Report: Coastal Restoration

This Phase II report of the GEMS project identifies metrics available to monitor the social and economic outcomes of a wide variety of coastal projects funded in the Gulf, using ESLMs to illustrate how these projects’ impacts cascade through the biophysical system to result in social and economic outcomes. Phase II expands the focus to assess socioeconomic metrics for 16 coastal project types, including habitat restoration, recreational enhancement, and water quality improvement projects.
