A sunny day out at Birdlings Flat walking on the beach and looking for agate with the family. A few observations.

We went to the rock museum as well https://www.geotrips.org.nz/trip.html?id=512

The Rakaia river was formerly known as Ō Rakaia meaning the place where people were ranged in rank. It was a traditional mahinga kai of the Ngai Tūāhuriri people of Kaiapoi.

The Rakaia river mouth is the site of many earth ovens that were used for cooking moa. Up to 1000 oven sites have been recorded in this area, indicating that large scale specialised moa-hunting for food supply was carried out here.

Jasper and I went for a walk with the Canterbury Botanical Society around the north side of the Rakaia River mouth.

Some notes-
Myoporum insulare from Australia and Tasmania planted instead of Myoporum laetum/Ngaio
Olearia albida a North Island Olearia
A large number of Lycium ferocissimum/African boxthorn alongside the path
Acacia melanoxylon/blackwood I think this is interesting because of the odd leaves that are not leaves but modified leaf stems called phyllodes. This is another Australian plant.
Apodasmia similis/Oioi one of my favourites because of the way it moves in the breeze and I see it nearly every day when crossing the South Brighton Bridge.
Senecio glomeratus a food for Magpie Moth caterpillars.
Iris foetidissima - saw many under the willows.
Fatsia japonica growing in a field of ivy
Selaginella kraussiana Alice’s adversary. A weedy African clubmoss that is difficult to eradicate. It is listed on the New Zealand National Plant Pest Accord.
Coriaria arborea/Tutu, Tom explained that this is poisonous and spread from further inland by floating down the river. Māori used to make a drink from the berries but had to remove the small seeds because the seeds are poisonous.
Senecio minimus- I am looking out for these plants because I am looking for Magpie Moth caterpillars that eat them.

From Akaroa, take the Akaroa Lighthouse Road. This is 11 km of steep, narrow rough road, suitable for four wheel drive vehicles.

From the carpark follow the road down past the foundations of the lighthouse keeper’s house and other buildings, to the site of the old lighthouse. Here there are fantastic views of towering cliffs along the coastline and towards the mouth of the Akaroa Harbour.

From the lighthouse view point, follow the old supply road down. It then passes a horse water trough and an original stone culvert. The road ends at a vertical iron ladder descending to a rock shelf in Little Haylocks Bay. The bay is within the Akaroa Marine Reserve and is home to a variety of wildlife including fur seals/kekeno seals which haul out on the rock platforms, white-flippered penguins/kororā and a number of seabirds.

This reserve overlooks the Akaroa Marine Reserve in the Akaroa Harbour.

The headland is very exposed to the weather. Be prepared for extremes of heat, wind and cold. Precipitous cliffs, steep unfenced drops and access to deep water means that children should be closely supervised at all times. It is recommended that children do not descend the ladder.

The original Akaroa lighthouse was replaced in 1977 by an automated light, and in 1980 the lighthouse was relocated to Akaroa.

I went with Peter in his 4 wheel drive vehicle. After we parked at the top car park we were passed by an electric vehicle that carried on down the hill. The electric vehicle got stuck further down the track and Peter and another walker spent the next hour helping him out. Peter had to use his four wheel drive and tow him back up the hill. The tow hook for the electric car was under the bonnet, it took some time to find it!

While we were in Haylocks Bay a tourist boat cruised in slowly to look at the seals and birds.

Some notes about my inaturalist observations

-Leptinella dioica alongside the path in partly shady and wet places next to the rocks. There was a large lovely green patch near the top of the iron ladder that goes down to Little Haylocks Bay.

• Interesting white lichen covering the rocks. Making the rocks look white, grey and cream from a distance away.
  -It was good to see New Zealand's native iceplant Disphyma australe growing in abundance over and inbetween the rocks.
  -Samolus repens, sea primrose, I have not seen this before.
  -Salicornia quinqueflora, I have only seen it growing in estuaries not high up on rocks. It was very green and healthy.
  -Goodenia radicans, remuremu, found in New Zealand, Australia and Chile. Another plant I have only seen in estuaries.
  Apium prostratum filiforme, Peter did not like the smell of this. But on the New Zealand Plant Conservation Network it says it is pleasant tasting and edible it could be more widely used as a substitute for celery.
  -Asplenium obtusatum, Paranako. A fern that is new to me. https://www.nzpcn.org.nz/flora/species/asplenium-obtusatum/
  -Chenopodium allanii, something else I haven't seen before and did not know what it was. On the New Zealand Plant Conservation Network it's conservation status is At Risk - Naturally Uncommon.
  -Possibly a slime mold, Phylum Mycetozoa growing on the wet rock in the shade. It was very orange I wonder it is orange because of the iron content from the rock. Very curious
  I know next to nothing about these things only that it is one of the earliest forms of life.
  -Crassula moschata, shore stonecrop. There was a nice grouping of this plus Goodenia radicans and Samolus repens that looked better than any human landscaping planting.

• Fur seals resting on the rocks in Little Haylocks Bay.
• Coprosma repens, Taupata
• Aciphylla aurea, Golden Spaniard on the roadside.
