Section 81.5 - General requirements(a) To be eligible for this program, the trees to be removed must have yielded at least 1.5 tons of dried prune/plums per net-planted acre during the 1999 or 2000 crop year. A net-planted acre is the actual acreage planted with prune-plum trees. Abandoned orchards and dead trees will not qualify. In new orchards diverted, qualifying trees must be at least 5 years of age (6th leaf), contain at least two scaffolds, and be capable of producing at least 1.5 tons per net-planted acre. The block of trees for removal must be easily definable by separations from other blocks and contain at least 1,000 eligible trees or comprise an entire orchard.(b) Any grower participating in this program must agree not to replant prune-plum trees on the land cleared under this program through June 30, 2004. Participants bear responsibility for ensuring that trees are not replanted, whether by themselves, or by successors to the land, or by others, until after June 30, 2004. If trees are replanted before June 30, 2004, by any persons, participants must refund any USDA payment, with interest, made in connection with this tree removal program.
