No Peacock blue

The Gouritz Biosphere meeting on Tuesday in Oudtshoorn was fascinating. It was also incredible to see what a few passionate people can achieve. All the talks were interesting, but Wendy’s detailed story of the Projects that have been undertaken and planned by GCBR was nothing short of miraculous. Lots of jobs are being created and whole communities have been lifted out of despair. And all these things have been done by a mere handful of people with a vision. It is awe-inspiring! Annelise also talked about the changes to Anysberg, where large tracts of land have been added to this magnificent Reserve. It is teeming with new species and Rares. There is no question that Jan and Annelise Vlok have been the drivers of this wonderful Anysberg initiative.

Jan was at the meeting and we chatted about our visit to Cyrtanthus debilis which is a Fire Ephermeral. You will remember from a previous Reportback, that Jan challenged us to find the pollinators. “If you are successful”, he said, “You can dress yourselves in Peacock Blue”. We found, a long-nosed fly, 2 different species of Ants and a predatory green Crab Spider. Surely this was enough to qualify? Well Jan didn’t think so. “I am not convinced, but by all means present your evidence to Steve Johnson of Natal University”. Oh dear, so for now, no Peacock Blue for the Outramps!

With a number of WAGS members on the Canoe Trail at Whiskey Creek, it was a fairly small party that arrived to walk from Myoli Beach to Oysterbeds on the Goukamma Beach on Wednesday. The mist was thick on the ground and stayed that way for the whole hike. Bill and I took off early on a fairly high tide. For a short stretch, we had to abandon the beach and plough through the thick sand, as the waves pounded the banks, which are eroding away. We stopped at Platbank and the rest of the party walked to Oysterbeds before turning round. Between Myoli and Platbank, we were looking for the Pleistocene aeolianites , which were featured in a recent article published by the SA Journal of Science. I am hoping that the photograph featured in the Album is one of them. No doubt, someone will be able to confirm or deny the id.

On Friday, five of us went up to Tierkop to see if Disa gladioliflora was in flower above the Hut and beyond Erica georgica Hill. This was because of a query from Steve Johnson to Jan Vlok. They are looking to research the pollinators and need fairly large concentrations of this beautiful Disa to do the work. There was no sign of the plants. We were on the early side, although we have seen them from early January to mid-April. Despite this setback, Tierkop never disappoints. Erica densifolia was in profuse flower, painting whole banks pink. There were also lots of other Ericas in bloom, as you will see from the Album. The magnificent Syncarpha eximia (Strawberry Everlasting) was stunning. Psoralea trullata (Rare) was dainty, scattered along the trail on the higher reaches.

The Forest stretch just after leaving the cottages is home to a number of Ozzie Invader Ferns (Spaeropteris cooperi) and there is one happily ensconced next to the water tank at Tierkop Hut. They always remind me of John Wyndham’s famous science-fiction novel, “The Day of the Tryffids”. We have repeatedly reported their presence to Cape Nature, Early Alien Plant Detection and a host of other people. They are for sale in nurseries all over the country and most suburban homes in George harbor a couple. They are not even listed on the Problem Plant lists. Don’t say, “You didn’t tell us” or “We didn’t know”! In the forseeable future this fern will have colonized the banks of all the rivers and streams in the Southern Cape and the beautiful Alosphila capensis (Cape Tree Fern) will have ceased to exist.

The LOT trip on Thursday was organized by Priscilla Burgoyne. Here is her story.
Klipfontein 22/2/2018
The day dawned clear and sunny and we set off to explore ±275 ha of a property north of Still Bay that had burned in the beginning of 2017.

After arriving, we were met by one of the co-owners and then proceeded off to explore. When the farmers say 4x4 only, you listen and Suzy promptly got stuck in the deep sand. No sweat, we proceeded on foot to find a host of interesting plants on sandy spits between a series of limestone hills (Canca Limestone Fynbos). The rainfall had been sparse but there were many interesting things flowering.

We picked up quite a few species of Centella of which Centella calcaria (NT), was a new one for us. Carpobrotus muirii (NT), Leucadendron galpinii (VU), Lebeckia gracilis (Endangered) and Delosperma inaequale (DDD) were a few of the red-listed plants that we came across. Bulbs had flowered and were in seed. Herbarium specimens were collected and these will be named in due course.

Our reputation for a meter a minute was earned when as we were driving out. Dave spotted the rare Agathosma eriantha (VU) with only a few plants in one patch, and we popped out to do a quick site sheet. Can’t go 50 meters without stopping for something! Also on our way out we spotted a few Leucospermum praecox (VU) in old lands. With an open invitation, all in all a spot to return to, especially when the bulbs are in flower.

We would love to see Protea venusta (Endangered) in flower. So if weather permits, SIM will head for Waboomsberg in the Swartberg on Friday. On Thursday, LOT is planning to collect a Selago burchellii specimen for the Herbarium at Villa Castollini. But with the long-term forecast looking iffy, there could be a change of plan on the day.
Between the Gouritz Biosphere Reserve and President Ramaphosa, (one is almost tempted to give him Rare and Endangered status) there is much being achieved in our beloved country on a daily basis. Hope Springs!

Palaeoecology of giraffe tracks in Late Pleistocene aeolianites on the Cape south coast
DOI: https://doi.org/10.17159/sajs.2018/20170266
Charles Helm et al. 2018
ABSTRACT
Until now there have been no reliable historical or skeletal fossil records for the giraffe (Giraffa camelopardalis) south of the Orange River or northern Namaqualand. The recent discovery of fossil giraffe tracks in coastal aeolianites east of Still Bay, South Africa, significantly increases the geographical range for this species, and has implications for Late Pleistocene climate and vegetation in the southern Cape. Giraffe populations have specialised needs, and require a savanna ecosystem. Marine geophysical and geological evidence suggests that the broad, currently submerged floodplains of the Gouritz and Breede Rivers likely supported a productive savanna of Vachellia karroo during Pleistocene glacial conditions, which would have provided a suitable habitat for this species. We show evidence for the hypothesis that the opening of the submerged shelf during glacial periods acted as a pathway for mammals to migrate along the southern coastal plain.

Significance:

The identification of fossil giraffe tracks on the Cape south coast, far from the area in which giraffe have previously been known to occur, is unexpected; conclusions about prehistoric conditions and vegetation can be drawn from this discovery.
