I was thinking about the invasive coqui frogs in hawaii, and how it became an extrem demage to the native wildlife there. I got a idea then. Hawaii like many other isolated islands have no native amphibians. So what if we release the fungus that corses Chytridiomycosis in effected areas there ? It is extremly specialized, and coudn't harm any native species, and selectivily eleminates, or atleast controll the frog population. Similar to how the moth Cactoblastis cactorum in Australia was used to controll the pickely pear infestation.
