Blue gums

DSCF0794.JPGBlue gums are they friend or foe ? I don’t know however lots of individuals believe they are bad for the black fish that inhabit the streams and river which flow through or past the trees. As far as I can see there are several ways a tree could be dangerous to fish the first is any herbicide that was used when the trees  were first planted second is there a chemical in the leaves that could cause problems and third is it the monoculture plantings, meaning that all the trees are of the one variety and if there is some chemical being exuded from the trees could the grouping of so many of the same trees cause a build up of chemicals that then make there way into the rivers and streams. Test will need to carried out to determine which one is causing the problem.
