    Dr. Danielle Treadwell and Mary Beth Henry (UF/IFAS Extension, Polk County) provide statewide leadership for the Small Farms and Alternative Enterprises program. This extension program serves Florida’s diversified crop and livestock farm operators of all sizes, but particularly addresses the unique challenges faced by small farms owners and proprietors including business planning, marketing and market access, food safety, resource conservation, and nutrient, water, and pest management. Visit the team’s website for a wealth of information on these topics and more: https://smallfarms.ifas.ufl.edu and keep up with current events on our Facebook page at https://www.facebook.com/FL.SFAEC/.

    Dr. Treadwell has provided leadership for Florida’s farm to school programs since 2012 and continues to serve as faculty advisor to Florida’s Farm to School and Community team now working in the UF/IFAS Family Nutrition Program with funding from Florida SNAP-Ed. The Farm to School and Community team consists of ten staff with experience and expertise in food and farming systems, plus additional staff at two farm to school food hubs (Alachua and Orange Counties). An interactive website describing the policy, systems, and environmental efforts of SNAP-Ed educators documented by our team is here: https://snapedpse.org/. Educational materials for school gardens includes our award-winning guide Grow to Learn: A Practical Guide for Successful School Gardens in Florida. 2014. (D. Treadwell, S. Park Brown, K. Brew and A. Prizzia, Eds.).

    Organizations throughout the U.S. are supporting a national initiative to expand the adoption of cover crops in farming systems as a strategy to conserve natural resources. Dr. Treadwell’s Cover Crops for Resource Conservation Extension program supports this initiative by conducting cover crop demonstrations and hands-on trainings on farms and on research stations as well as serving as board member and Co-Chair of the Outreach and Communication Committee of the Southern Cover Crops Council.
