If only a few plants definitely worth removing while manageable

Hey @Berno
Did you get a chance to treat this one? Was it a larger infestation, or just one or two plants? I suspect that given the nature of the site (old sheep camp), that it is well established. Happy to follow up on it if you like.
Cheers,
Ben

Hi @RangerBen, we'll go and have another look at the Wanni Hills site and confirm. From memory a few dozen plants aside the ridgeline track. We could remove them but it depends on the plant nos. Possibly a back pack spray is the go for this site? That approach (back pack spray) would likely be the go for the Mt Taylor sighting which appears to have many plants in a small area. That site also probably needs a return survey - which we could also do and confirm. We'll re-check both sites and get back shortly! Cheers, Berno
