Mississippi State Wetlands Protection Laws and Policies: Disconnect Between Implementation and Conservation Practice

Mississippi wetlands provide flood storage, water-quality regulation, habitat, shoreline protection, and climate resilience, yet long-term loss and degradation continue despite an extensive body of federal and state law. This paper examines persistence as an environmental governance problem rather than as a purely doctrinal legal question. It uses a qualitative analysis of legal, policy, and agency documents relevant to Mississippi wetlands, organized around jurisdiction, institutional fragmentation, permitting, enforcement capacity, and monitoring and participation. The analysis centers on 16 core federal and Mississippi laws and policies. It supplements them with agency guidance, public permitting materials, and selected scholarly sources to assess how formal legal protections operate in practice across the state. The findings show that Mississippi has a substantial formal framework for wetland protection, but that framework remains uneven in scope, geography, and implementation. State authority is most visible in coastal wetlands, whereas many inland wetlands depend more heavily on federal jurisdiction, interagency coordination, and administrative follow-through. The review further shows that legal accumulation has not produced consistent conservation outcomes because fragmented authority, variable enforcement, limited monitoring capacity, and land-use pressures weaken implementation. Recent jurisdictional narrowing after Sackett v. Environmental Protection Agency intensifies that asymmetry and increases uncertainty for inland wetland protection. The paper argues that improving outcomes will require governance reform as much as legal reform. More effective protection depends on clearer jurisdictional triggers, stronger interagency coordination, more transparent permit administration, improved monitoring and compliance systems, and closer integration of regulation, restoration, and land-use planning. The study contributes to wetland governance scholarship by showing that legal accumulation alone does not secure conservation outcomes when fragmented authority, uneven implementation, and weak institutional integration persist.
