Mission The mission of The Nature Conservancy is to conserve the lands and waters on which all life depends. 
Background The Nature Conservancy has worked to conserve Oklahoma’s magnificent landscapes and unique biodiversity since 1986. Using a strategic, science-based planning process, called Conservation by Design, we identify landscapes that, if conserved, promise to conserve biodiversity over the long term. The Oklahoma Chapter owns or protects 12 preserves totaling over 100,000 acres (156 square miles). 

1.  Developed and published for public use a site wind right gis tool to assist in the proper siting of wind farms.

2.   Acquired approximately 3,100 critical acres of native prairie along a mile of the Blue River in south central Oklahoma to improve water quantity and quality for downstream users.
3.  Safely conducted prescribed burning of over 15,000 acres to ensure health of ecosystem. 

1. Four Canyon Preserve Endowment                                  $950,000

2. Tallgrass Prairie Preserve - Cowboy Family Home         $250,000
3. Oka' Yanahli Preserve - Maintenance Facility                 $100,000 
4. Operational Funding                                                         $500,000 
CEO/Executive Director Statement

Natural places seem to have this magical ability to shape us as human beings. In a subtle way, each place is like a familiar person, speaking to us, teaching us about their long list of experiences, passing on timeless wisdom much as an elder mentor might. These places also are a critical part of our identity as a state; Oklahoma is so very tied to this backdrop—the landscapes and rivers we all know and love run through the veins of our state. And although we all recognize this importance of our landscapes, we continue to learn about just how important these places are to our wellbeing, our economy, and our future. Our grasses and soils help to feed our nation, our beautiful landscapes and rivers help nourish our economy, and our natural resources help fuel a growing population. Everything we do is inescapably tied to nature. Forgetting this important fact is akin to denying the importance of our heart or our lungs – we could never live without them.


This special link between people and nature drives the work of The Nature Conservancy. We use science to find the collaborative solutions that will conserve Oklahoma’s last great places for generations to come. By doing so, we can protect our economy and our quality of life. We call this effort conservation for natureandpeople. And no one has done it better over the last 30 years. We’ve helped to directly conserve over 100,000 acres here in Oklahoma, all through private action.


But as we have celebrated these many successes, we have come to realize that conservation is not as simple as we once thought—setting aside one place at a time may make a stride forward, but it is simply not enough. We need to use our preserves in a way that will influence the landscapes beyond our borders. Helping ranchers improve the habitat on their land while improving the efficiency of their operation; showcasing buffer strips along our rivers to improve water quality in our drinking water; and developing sophisticated tools that help companies site their drilling in places that will minimize the impact to wildlife are a few of the many ways we want to leverage our places to advance conservation on a whole new scale.


The urgency is greater now than it ever has been before. Oklahoma is moving forward at a staggering pace. This growth presents a unique opportunity to conserve our last great places in a way that can embrace our growing prosperity while conserving our natural world for future generations. At the same time we protect the future of our drinking water, our ranching, our economy—our way of life.

The Oklahoma Chapter owns or protects 12 preserves and properties across the state, currently totaling over 100,000 acres.  These preserves conserve examples of ecosystems ranging from the unique rolling hills of the mixed and shortgrass prairies of western Oklahoma to the diverse forested ridges, valleys and river systems of the Ozarks and Ouachitas in eastern Oklahoma to the largest protected remnant of tallgrass prairie left in the world in northeastern Oklahoma. 
We operate through collaborative and creative approaches that foster conservation under a philosophy that seeks an intelligent balance between economic prosperity and conservation of ecologically sensitive sites.  We use a strategic, science-based planning process, called Conservation by Design,which helps us identify the highest-priority places: landscapes that, if conserved, promise to conserve biodiversity over the long term.  In other words, Conservation by Design allows us to achieve meaningful, lasting results.

Program Long-term SuccessHelpDescription of the ultimate change(s) that will result from this program. This may be far into the future or represent an ideal state. To date, we have protected around 80,000 acres of some of the most exceptional landscapes in Oklahoma.
Program Success MonitoringHelpDescription of the tools used to measure or track program impact.


For more than a decade, The Nature Conservancy’s work has been guided by a framework we call Conservation by Design — a systematic approach that determines where to work, what to conserve, what strategies we should use and how effective we have been.

Conservation by Design marries a collaborative, science-based approach with key analytical methods that we use to assess and plan our actions. In the more than 30 countries in which we work, Conservation by Design enables the Conservancy to preserve healthy ecosystems that support people and host the diversity of life on Earth.



To us, protecting nature isn’t about putting up fences around pristine places to keep people out. We’re about protecting the places and resources we depend on for the benefit of all species—plants, animals and people. To that end, we are advancing conservation science, developing multi-use strategies, catalyzing partnerships and improving policies in key conservation areas (see below).

Population Served General/Unspecified
Program Long-term SuccessHelpDescription of the ultimate change(s) that will result from this program. This may be far into the future or represent an ideal state.

-         Rangeland and Wildlife Management – We are exploring responsible approaches that offer ranchers and wildlife a chance to co-exist, with a benefit for both.

-         Invasive Plants in Oklahoma – We helped create the Oklahoma Invasive Plants Council to work on effective management of biodiversity threats from invasive plants.

-         Fresh Water – Of all the water on Earth, less than 1% is currently available for human uses or consumption.  TNC is using creative approaches to ensure both quantity and quality of fresh water for future generations of Oklahomans.

-         Wind Farm Development – The placement of utility scale wind turbine farms in the region is a relatively new land use development.  We have developed siting tools and work with wind power producers to avoid fragmentation and destruction of sensitive habitat for threatened species, like the Lesser and Greater prairie chickens.

Disaster Programs
Description We do respond to wildfires around our preserves and, in some cases, are the rural fire department.  This is done on a voluntary basis.
