Bell Miner Associated Dieback (BMAD) Dieback is a condition that begins on the leaves and spreads to the branches, which can lead to tree death. Introduction Factors contributing to bell-miner-associated dieback (BMAD) are largely unresolved (Wardell-Johnson et al. In the case of BMAD, sap-feeding parasitic insects feed on eucalypt leaves and their protective sugary coating known as lerp, is fed upon by the bell miner. Serious consideration needs to be given to the wisdom of trying to continue to manage these forests for industrial logging. The Task: To participate in a field trip and conduct a deep exploration into the environmental impacts of Lantana and in particular the contribution of Lantana to the problem of Bell Miner Associated Dieback.
