Growing up in the Bendigo region of Dja Dja Wurrung country (Victoria Regrarians founder Darren J Doherty was a child of the forests that surround Victoria’s 3rd largest city. The family farm ‘Myrtledale’ was fronted by the ‘Wellsford Forest’—which is predominantly mixed height-class re-growth from the gold-mining era when it was mostly cleared to support what was the world’s richest gold field. In the 20th century many of these regrowth forests have been managed by the Victorian Government with a version of ‘coppice with standards’—a version of the same management persisted on the family farm as well, providing a wide range of forest products including biodiversity, shelter, building & fencing materials and firewood. With this background it should be no surprise that the integration of woody plant systems into agricultural landscapes have been central to what Regrarians have done for more than 3 decades.

Generally the more productive a conventional agricultural landscape, the less likely that woody plant ecosystems will be present. There are many reasons for this—most of which are cultural as woody plants have long been viewed as being competing with target crops and pastures for moisture, nutrients and light. There is more than ample empirical and scientific evidence to demonstrate that the most productive agroecosystems integrate a proportion of woody plant systems—the degree to which and composition is a most rewarding part of any farm planning process.

Regrarians has been a key advisor and partner of Propagate Group PBC in the USA since it was incorporated in 2018. We are also proud ambassadors of their world-leading ‘Overyield’ agroforestry design, evaluation and monitoring software. We are also deeply involved with some of the largest agroforestry projects in the world.

2008 - Tananaki Farm (VIC, AU) - Interrow mixed species planting established in 1998, laid out using Keyline geometry. Alternating 4m wide rows of Acacia mearnsii (late black wattle) & Eucalyptus cladocalyx (sugar gum)—the (successful) purpose being that the faster growing wattles would provide frost protection for the frost-sensitive sugar gums
