Leaf miner attack needs attention
Far worse than any local decline in peppermints is the massive ecological disaster with the leaf miner attack on flooded gums along our river, creeks and wetland areas.
This native insect species is destroying or having a significant negative impact on trees from Margaret River to Kojonup and Boddington to Harvey.
Year after year, mature and immature trees are being affected, each time causing further weakness, ultimately resulting in death of these trees.
If they disappear, considerable soil erosion and loss of habitat will result. And yet, no research appears to be undertaken.
It is a massive problem, which demands urgent attention and funding.
Local small-scale trials using selective baited pheromone attractants and direct injection with systemic insecticides could be conducted, but ultimately biological controls are the only solution given the size of area.
Government agencies need to make this a priority before massive ecological collapse.
