Privately owned and operated, CCA is open by appointment only and does not charge entry fees. Run by volunteers, there is no paid staff.
History
Dr. Dean Nicolle began looking for land between Mount Compass and Strathalbyn in 1990 to create an arboretum. The specific soil type he was looking for had to be well-drained, limestone-free, and with a neutral or slightly acidic pH. CCA was established in 1992. The site has a Mediterranean climate with annual rainfall.The first seed plantings of 18 eucalypts occurred in 1993. All seed collection points were marked with a GPS location and an herbarium voucher. Using trial and error in choosing planting distance, some trees that were initially planted too close are being replanted.
