Tidal wetlands are valuable coastal ecosystems, providing nursery habitat for commercially and recreationally important fisheries species, refuge for threatened and endangered species, and critical storm surge and flood protection benefits to communities. Despite numerous efforts by partners to protect and restore tidal wetlands in Texas, they have been disappearing due to subsidence, sea level rise, erosion and coastal development. To minimize further tidal wetland loss in Texas, The Nature Conservancy and a broad coalition of 34 partner organizations are working together to implement the Texas Wetland Action Mapping (Texas WAM) project. This collaborative, science-based initiative coordinates statewide action and aims to catalyze collaboration and funding opportunities for tidal wetland restoration and conservation. A Texas Wetland Action Mapping Plan was developed in coordination with this working group and is the first statewide plan focused on tidal wetland conservation and restoration developed in recent decades. During a series of regional workshops and targeted planning sessions conducted over two years, the working group developed a shared set of goals and strategies and prioritized locations where working group members and partners could implement action. These action areas were selected using a participatory mapping process and planning tools developed by the Texas WAM project team to help guide wetland restoration and conservation investments across the coast.
