This project assessed acacias in the three trials established in 1992 for their wood volume, bark thickness yield and stem form. Non-destructive bark samples were harvested from each provenance of the twelve acacia species represented across the three sites and these were analysed for their Stiasny value and polyflavanoid content. Further bark samples from a single provenance of ten of the species were destructively harvested from the Darkan (Bowelling) site for bulk tannin extraction. Bunnings Timbachem and DynoIndustries assessed the freeze-dried bark extracts for their adhesive attributes. Wood discs cut from the base of the trees and at breast height were used to assess wood density for ten of the species. The stumps were observed for coppice a year later.
