General Notes Very useful plant; for erosion control (fibrous roots), shelterbelts, and as wildlife habitat. Bursaria flowers attract many insects, including some that feed on the saw-fly larvae that infest eucalypts, and wasps that parasitise pasture grubs. It is good shelter for birds and Eastern Barred Bandicoots. Timber is pale, fine grained and tough, and seasons well due to very little shrinkage. A source of nectar for honey production. Resistant to wildlife browsing due to its unpalatability. Leaves contain aesculin, thought to absorb ultra violet rays and apparently used by early settlers to prevent sunburn. 4-6 weeks stratification @ 4oC = Germination may be enhanced. Not suitable below powerlines.
