Summary

This package includes a detailed habitat map, general habitat map, and georeferenced imagery from 2015 for the Natural Resource Damage Assessment (NRDA) Caillou Lake Headlands project area (TE-0100), also known as Whiskey Island. The project created 170 acres of marsh habitat and 917 acres of dune and beach habitat on Whiskey Island in Terrebonne Parish using material dredged from Ship Shoal. The habitat maps are part of a suite of Whiskey Island habitat maps for the years 2012, 2015, and 2017–19, which span the time period before, during, and after the restoration project was conducted. For more information on this restoration project, see the project page on Louisiana Coastal Protection and Restoration Authority’s (CPRA) Coastal [...]

Purpose

Barrier islands provide numerous invaluable ecosystem services including storm protection and erosion control for the mainland, habitat for fish and wildlife, salinity regulation in estuaries, carbon sequestration in marshes, recreation, and tourism (Barbier and others, 2011). Since the resources they provide are integral to economic and environmental interests, it is imperative that they are managed in a way that ensures resiliency and the continued provision of ecosystem goods and services over time. These islands are very dynamic environments due to their position at the land-sea interface. Storms, wave energy, tides, currents, and relative sea-level rise are powerful forces that shape barrier island geomorphology and habitats. The habitat products developed through this effort were used in an analysis of avian habitat availability and patterns of distribution, abundance, and behavior before and after restoration activity, which can help land managers target restoration activities that produce the best outcome for multiple stakeholders, including preserving habitat needed by species of conservation concern. Additionally, the maps will provide a powerful tool for tracking changes to barrier island habitats over time. Please consult the accompanying readME.txt file for information and recommendations on the contents of this dataset (i.e., dataset and recommended symbology).
