Field Day: Organic and Sustainable Rural Living, Christmas Trees; Medicinal Herbs; Water Conservation; Healthy Lifestyle; Wildlife Preservation @ Dustin (Buzzard Roost Ranch)
Apr 28 @ 9:30 am – 3:00 pm
Field Day: Organic and Sustainable Rural Living, Christmas Trees; Medicinal Herbs; Water Conservation; Healthy Lifestyle; Wildlife Preservation @ Dustin (Buzzard Roost Ranch) | Dustin | Oklahoma | United States

Stephanie and Gene Jeffords run a you-cut Christmas Tree operation. After years of dealing with herbicide sprays to maintain healthy trees, they worked out a system of twice-a-year pruning which has eliminated their need to spray.

Field day activities include walking the property, identifying local wild medicinal herbs and edibles, discussing how fracking is impacting the agricultural water supply on-site, looking at wildcrafting opportunities, and discussing co-use while preserving wildlife habitat and protecting endangered species.
