Protecting What Matters: Wetland Stewardship in Partnership with the Chickasaw Nation

Wetlands are some of the most valuable and often overlooked systems on the landscape. They play a critical role in improving water quality, reducing flood impacts, supporting wildlife habitat, and maintaining the overall health of watersheds. In regions like south-central Oklahoma, where water resources are closely tied to both environmental and community well-being, understanding and protecting wetlands is essential.

That importance is driving a collaborative effort between the Oka’ Institute and the Chickasaw Nation’s Department of Land Sustainability and Services. Through this partnership, and alongside broader grant partners working toward shared land and water stewardship goals, the project aims to strengthen ecological resilience while supporting informed, long-term decision-making on tribal lands.

Applying Science to Stewardship

As part of this effort, the Oka’ Institute is leading two key components: a wetland assessment and delineation, followed by the development of a practical wetland management plan for the Kullihoma and Brunk properties.

Oka’ staff, including team members trained in wetland delineation, will use field-based science and GIS tools to identify, map, and document wetland features across the properties. This includes evaluating hydrology, soils, and vegetation indicators to better understand how these systems function on the landscape.

Using GPS and mapping technology, the team will establish approximate wetland boundaries and produce GIS shapefiles, site maps, and a summary report of findings. These materials are designed to support the Chickasaw Nation’s planning and stewardship efforts, providing actionable insights tailored to their needs rather than serving as a formal regulatory delineation.

From Data to Action

Building on the assessment, the Oka’ Institute will develop a wetland management plan that translates field observations into practical strategies.

The plan will summarize current site conditions, highlight key ecological functions, and outline recommendations to maintain and enhance wetland health over time. This may include approaches for seasonal maintenance, invasive species management, and adaptive practices that respond to changing environmental conditions.

Importantly, this work aligns with the Chickasaw Nation’s broader priorities around climate resilience and land stewardship, ensuring that wetland management contributes to a larger, integrated vision for the landscape.

Grounded in Collaboration

This project is built on close coordination with Chickasaw Nation staff to ensure the work reflects both ecological priorities and cultural values. Throughout the process, data, maps, and reports will be shared securely and managed in accordance with the Nation’s data stewardship practices.

Looking Ahead

By combining on-the-ground science with collaborative planning, this effort helps create a clearer understanding of wetland systems and how to care for them. It is a step toward strengthening the health of the land, supporting water resources, and advancing long-term stewardship across the region.
