#39 The nuances of farm forestry and the opportunities of integrating biodiversity with Campbell Mercer

Campbell Mercer owns 40ha outside Melbourne, Australia where he has set up a world class olive farm - producing award winning organic olive oil. Campbell uses a variety of fascinating agroforestry practices, from windbreaks to farm forestry and silvopastural systems. We have an in-depth conversation on small scale farm forestry, from design considerations to harvest and selling. We also discussed the Keyline cultivation pattern and its implications for tree planting, finishing off with the various functions of his windbreaks and their interaction with neighbouring olive trees. Overall, Campbell has not been shy to make use of tree systems to align his production with the ecology he works in. He has managed to harness the ecosystem services provided by trees whilst ensuring they remain economically productive.TABLE OF CONTENTS02:42 Story and context of the farm11:09 Why go organic? 13:28 Use of black wattle19:52 Selling small quantities of timber 23:16 Main objectives of agroforestry on the farm27:56 Design of the systems39:04 Sawing material 40:56 Drying the wood43:37 Pruning46:35 Profitability of timber plantations57:22 Interactions between grass and trees01:01:24 Planting along the keyline pattern01:05:17 Feedback on deep ripping and swales01:10:46 Would you do keyline again? 01:19:41 Windbreaks01:28:34 Choice of species in windbreak01:38:17 Production from them01:40:28 Interactions between windbreak and olive trees01:45:00 Improved overall productivity • RESOURCEShttps://mannahillestate.com.au/https://www.instagram.com/mannahill.estate/• GET IN TOUCH www.regenerativeagroforestry.org• SUPPORT US www.gumroad.com/regenagroforestry• FOLLOW US on Twitter, Facebook, LinkedIn and Instagram Hosted on Acast.
