This seaweed is a bit of a worry

[harm_less]

I think the determination to keep NZ pure is pissing into the wind... Unless we are putting serious investment into measures arising from climate change, then funding programmes like exotics eradication is just a complete waste of money.

But try telling DoC that...

One example of that line of thought is the risk of disease vector mosquito varieties surviving in New Zealand. All it takes is a pool of water in an imported item containing mosquito larvae and they're in NZ. Previously the varieties that carry the likes of malaria or dengue fever haven't been able to survive in our climate but as temperatures rise including winter chilling becoming less severe our natural buffer to such invasion is eroded.

The same scenario applies to plants, aquatic organisms and even fungi (myrtle rust?). Climate change will throw up all sorts of issues many of which we may not have even contemplated yet.
