In response to the overwhelming support of oak research and conservation expressed by our members at the last Triennial Conference in Davis, CA, and in light of the fact that at least 20% of the world’s oak species are threatened with extinction, the IOS has launched its Oak Conservation and Research Fund

To guide Fund priorities, we recently conducted a survey that was answered by over one quarter of IOS members. It revealed that restoring habitat, ex-situ conservation, field survey and population monitoring, education, and population reintroduction/reinforcement were high priority Fund activities. 

Encouraged by your research and conservation priorities, we aim to raise money to entertain proposals and start work.
