Andrew Cameron: Avocado Orchard Regeneration & Vertical Stacking
By Tweed Shire Council
In this September 2024 video from Tweed Shire Council's Farm Walk and Talk series, Andrew Cameron details his transformation of an avocado orchard using organic and regenerative principles. He employs 'vertical stacking' by integrating pasture-raised chickens, Davidson’s Plum, and companion plants to boost biodiversity, pollination, and soil health. Key methods include stopping all chemical use immediately to allow native biology to recover, conducting thorough soil tests, and observing plant and animal indicators for tailored interventions. Cameron uses low-succession plants and a mix of about 330 tree species as 'tall tools,' including native fast-growing, silica-building, nitrogen-fixing trees like casuarina river she-oak that interact beneficially with avocados. Chickens contribute to pest control, nutrient cycling, and ground cover management. Practical steps cover understanding soil profiles, reintegrating plants progressively, and leveraging biodiversity for resilience. The approach enhances ecosystem services, reduces inputs, and improves avocado yields through natural synergies. Filmed on-site, the video offers visual demonstrations of orchard layout, plant interactions, and animal integration, providing practitioners with a replicable game plan for regenerative transitions. Cameron emphasizes feeling through site-specific adaptations, making it a concrete case study for organic avocado growers seeking regenerative outcomes like healthier soils and robust trees.
