Our Mission & Vision

The Ozark Chinquapin Foundation (OCF) is a non-profit organization of outdoors-men and women with a vision of restoring the Ozark Chinquapin to its historic native range.  Through our efforts, and those of hundreds of volunteers over the last decade, we are attempting to establish a viable seed base through research and the manual cross-pollination of surviving trees. Our goal is to develop a 100 % pure Ozark Chinquapin that is blight resistant, and distribute the seeds to everyone interested in helping. 

Join The Ozark Chinquapin Foundation

If you are interested in joining our efforts and obtaining seed, we welcome your help and support! Membership in the Ozark Chinquapin Foundation is $30.00 per year.  If you would like to give a donation with your annual membership you can do that typing in a custom amount or choosing one of the options on the form. 

Seed from the Ozark Chinquapin are still very rare and seed with resistance even rarer. However, every year we are able to ship seed with better resistance than the year before. Every year we mail our annual members seed collected from our research test plots. There is no guarantee these seed are blight resistant. However, the parent trees these seed were collected from are large (11″ – 21″ Dia.) 100% pure Ozark Chinquapin trees that exhibit varying levels of resistance.

Members will have their seed shipped in January-March 2020  in order of membership received. With your membership you get 3-5 rare seed depending on availability, growing instructions, updates on restoration progress and the first opportunity at resistant seed as they become available from research test plots.

Thank You for your help and support!
