Recycling - Tohe (90 Mile Beach) Style

Sooner or later out on the Tohe a foolish driver who does not know what they are doing will get their vehicle so stuck that's not possible to get it out.

The above photo shows a car stuck after a turn of the tide.

Within 4 tide turns there will be no sign of the car and I have often wondered what happend to it. I knew sooner or later it would be broken down by mother nature but did not realise to what extent recycling went to out here until we came across this yesterday.

Seems the tyre has been recycled and has become a home for goose barnacles, green alga and crabs. Nice to see that some human rubbish in the ocean can help instead of hinder :D

Trimusculus conicus - A Common Limpet to Seek Out

Found throughout NZ but we only have 3 obs for this, two from the real far north and one from Rakiura, Stewart Island!

NZ Coastal Marine Invertebrates, Cook, Pg 464 has this to say:
Common. May not be seen unless sought
Yep - that would be about right *LOL*

So we need to find these. They live in well shaded conditions, on cave walls, under large stable boulders with plenty of wave movement.

So lets get more obs for this common limpet that is not common on this site!

Journey to the Sea Anemone Cave

Last week we found a cave that had a strange sea anemone growing in it (https://inaturalist.nz/observations/15675292) , so I said we would go back and try and get better photos and on Monday that is what we did.

Now this sea cave is right up at Scotts Point, the northern end of Ninety Mile Beach, affectionatly called the Tohe and the only access is along the Tohe. Of course that has always been dependant on the tides but until recently when mother nature decided to close Te Paki there was an escape off ramp about 2kms south. Now the closest on and off ramp is 55kms south which means that if the tides were missjudged there was not a close escape route.

Monday was a .6m low tide but the swells were about 2m. When @indeynz, my trustee side kick, photo assistant and walking mollusca encyclopeadia and I got to the Tohe about 2 1/2 hours before the low, I could see straight away that it was running high, but after reading all of the tohu out there, I decided to go up and see if we could make it.

Make no mistake though, this decision was based on an intimate knowlege of the Tohe, tides and moods and I would not recommend anyone to do this journey in the condition that it was out there without that intimate knowlege.

Now lately when we have headed up there I only have my underwater camera and each time I would see a manu out there I'd say, "Ahhh - I wish I had my good camera!" This time however I did, hence all of the bird photos from this day and some good kekeno / seal photos :)

After getting pass the Bluff - which can be a cut off point - we were totally shocked to see this a bit further up! I have NEVER seen that out there!

We finally arrived at the northern end at about 40mins before the turn and the water was high. Where it is usually exposed there was waves coming in. So after a quick study of the area we decided to see if we could get around to the cave. This involved scrambling over rocks and hugging the cliff so we didn't get splashed by the waves, or worse case senario washed off.

Getting around the point there was water into the cave and at the foot of the cave, a direct result of the turbulant seas that had dumped alot of sand in this area. We surprised a kekeno - fur seal - who was on the rocks on the other side of a small gut and it took off. We then jumped across the gut and walked over the rocks and into the cave.

Once in there we quickly did our photos, mindfull of the time and tides and in fact there was a moment where we had to scramble up the sides as the waves came crashing in.

Getting the photos home and looking at them I see that there are so many other things I did not see at the time so do not have good photos of, so we will plan a serious cave photograhing expedition at a later date, when the swells are not so high!
