What the record supports
The 2022 Forest Stewardship Plan reported that no agrochemicals were in use at that time and that compost and organic fertilizer were produced with rabbit manure from the biodigester. The 2026 NRCS plan survey recorded western honey bees and carpenter bees on site. The setup provides a way to measure the nutrients and materials returned to the farm.
