Who We Are
Our membership includes property owners and other interested individuals within a five county area in northeastern Wyoming.

We value the unique landscape of which we are privileged to be a part.

The conservation strategies we investigate, implement, and promote are responsible, science-based, long-term, and landscape in their scale.

The Thunder Basin Grasslands Prairie Ecosystem Association is a non-profit organization which provides private landowner leadership in developing a responsible, science-based approach to long-term management of member's lands.  Current membership includes 19 livestock/agricultural producers and 14 energy production companies as well as 3 associate members. Thanks to our members for your help conserving and responsibily managing the rangelands in our coverage area.
