Toxic algae
Toxic algae is known to bloom in awa/rivers during the warmer months, so it’s a great time for a refresher on how to spot it.
Toxic algae grows on the bottom of riverbeds and appears as thick dark brown or black mats that have a slimy or velvety texture and musty smell.
These mats can come loose and wash up on the edge of the rivers, or form ‘floating rafts’ in shallow areas. As they dry out, they turn light brown or white and look like dried leaves or cowpats.
If you are in any doubt, keep your whānau and animals away from the river.
Some Choice News!
DOC is rolling out a new tool to help figure out what to tackle first when it comes to protecting our threatened species and the things putting them at risk.
Why does this matter? As Nikki Macdonald from The Post points out, we’re a country with around 4,400 threatened species. With limited time and funding, conservation has always meant making tough calls about what gets attention first.
For the first time, DOC has put real numbers around what it would take to do everything needed to properly safeguard our unique natural environment. The new BioInvest tool shows the scale of the challenge: 310,177 actions across 28,007 sites.
Now that we can see the full picture, it brings the big question into focus: how much do we, as Kiwis, truly value protecting nature — and what are we prepared to invest to make it happen?
We hope this brings a smile!
