Elected representatives in government are in charge of the policy and funding that can make or break saving threatened species. Their decisions and actions matter.
Mallee has or used to have 39 threatened animals within its boundaries. One of them is me, the Silver Perch.
We took care to attach appropriate images that are as close to representative of each species as our resources and the availability of images allowed. However, we could not ensure perfect accuracy in every case. Some images show species that share the same genus but not at the species or subspecies level.
