Port St Johns: a little heaven on earth!

Port St Johns or PSJ as it is affectionately known by many, is a small village located on the Wild Coast. This beautiful village got its name when sailors mistakenly identified the Mzimvubu River mouth as where the Portuguese ship Sao Joao “St John” was wrecked in 1552. It was a port until sediments made the river mouth shallow.

The beautiful landscape, the humidity, and friendly environment welcome you as you enter the town. These all give refreshing vibes.

A field trip to PSJ was the best way to begin my year. With the Eastern Cape Custodians of Rare and Endangered Wildflowers (CREW) node recently founded, this means a lot of regions in the province are still under-sampled, the former Transkei being an example, hence the trip to  PSJ. It is well known that our plant diversity is constantly threatened by overharvesting, habitat loss, frequent fires and climate change amongst many other factors. The trip was therefore aimed at surveying and monitoring plants of conservation concern in this region of the former Transkei. During the trip I assisted in creating ID sheets, searching for the targeted species, filling in data sheets and collecting some plant specimens. 

During the creation of the ID sheets, location data for the target species was obtained from labels on specimens at the Selmar Schonland Herbarium at Rhodes University and from SANBI’s BRAHMS online database. Since we had Thutani Mpunga as a guide on this trip, he also helped in identifying the locations of target species as he was familiar with many of them. The data filled in during the field work for each species is later fed onto the CREW database, where even the species that were not found are recorded as null records to show that the team did look for the species. The species are then targeted for the next field season and more research will be done. This will include research on the flowering times that may be different from the ones we previously obtained, which could explain why we did not find the plant because the flowering times were incorrect.

On arriving at PSJ and seeing the beautiful transition from the previous town, one can ask are these areas neighbors? I remember driving through PSJ and being impressed by the diverse environment, ranging from a beautiful landscape covered in green and lush vegetation to the beautiful scenery of the mountain surrounding the village. While gazing at this, you instantly feel the PSJ’s humid air reviving your body and soul, taking away the exhaustion of traveling the long-distance! The beautiful green-bluish water from the Mzimvubu River says ‘you just cannot take your eyes off me’. Mind you, this was only the day of arrival, fieldwork starts the following day and the curiosity of what more beautiful things you’ll be seeing kicks in.

Arriving at our accommodation at Silaka, we found some more breathtaking views and vegetation. No wonder they decided to declare this place a nature reserve! Protection from threats for this beauty is needed. One major threat the area faces is that of alien invasive plants. As they always do, they find residence along the river banks and wherever they can thrive. Although there is still some natural vegetation, proper management for these aliens needs to be implemented immediately. Let us hope the new project by Department of Environmental Affairs (DEA) will fight this battle.

Anyway, from a nature conservator’s point of view, that’s the only depressing part I can report. Our journey to nearby localities such as Magwa Falls, Fraser Falls and Goss Point lifted the energy levels and I observed the role nature plays in the livelihoods of the local people and how this contributes to their positive interactions with their environment. Skillfully built Xhosa huts on the steep slopes, some facing the waterfall and gorges, young girls and women gathering firewood, and boys swimming in the river -- these affirm that we indeed have good stories to tell about our country!

The beauty of this place was evident even before my team and I started looking down and searching for our special plants. Successfully locating these plants always gets me excited so you can imagine how I was like a kid in a candy store when we spotted our first special!

As mentioned earlier, CREW work entails monitoring species of conservation concern in their natural habitat. This field trip was conducted to search for six specials: Podranea ricasoliana (Vulnerable-VU), Leucadendron spissifolium subsp. natalense (Near threatened-NT), Colubrina nicholsonii (Vulnerable-VU), Cyathocoma bachmannii (Vulnerable-VU), Eugenia verdoorniae (Near threatened-NT), and Eriosema latifolium (Vulnerable-VU) for monitoring purposes. The Vulnerable (VU) and Near threatened (NT) categories indicate conservation status that reflects the risk of extinction of plant species according to the national Red List of South African plants.  Therefore when a plant has VU status, it means that the species is facing a high risk of extinction due to environmental factors and further loss to the natural habitats should be prevented. And when it is Near threatened it means there are still some subpopulations of the plant in the wild but there is a need to minimize loss of habitat as the plant nearly meets the criteria for the threatened category (VU).


Day 1: Magwa estate and Ntambalala forest field trips.

It was a fruitful trip as we managed to find two of the targeted plants. At the Magwa estate, we located Leucadendron spissifolium subsp. natalense (NT) - a fast growing multi-branched bushy shrub. The male and female plants are separate. The plant occurs in the Eastern Cape and KwaZulu-Natal Provinces and it is a South African endemic. Taking specimens of the plant was a challenge as some individuals grew at the edge of a cliff. Sensibly, I planned to collect specimens from plants that were on flat land but one on the cliff had beautiful fruits so I needed to take a specimen from that plant. Our guide saw that I was struggling and came to my rescue. As we continued walking through the field we saw the likes of the Large-flowered Sebaea Exochaenium grande, an abundance of Apocynaceae species, one of which was Pachycarpus asperifolius, some beautiful orchids along the stream and a special, Stangeria eriopus (VU). S. eriopus is distributed from the Bathurst district in the Eastern Cape to the south of Mozambique. This plant is often mistaken as being a fern due to its fern-like appearance and the leaves are folded in fronds (as in ferns) before they open.

Lunch by the waterfall

After lunch near the waterfall, we headed off to Ntambalala Forest where we successfully located P. ricasoliana (Port St. John’s creeper). Because it was easy to find the creeper along the stream and forest margins it makes one wonder if it is not easy for harvesters to also locate and collect it? The creeper is an evergreen climber without tendrils and it belongs to the family Bignoniaceae. The species only grows at Port St John’s and according to the Red List, it is a South African endemic. However, according to Malan and Notten (2002), many South African botanists suspect the plant is not indigenous to South Africa and think it might have come with outsiders during the slave traders’ period.

While at the site I saw an Eriosema. I got excited that it might be the one we were looking for, the vulnerable Eriosema latifolium, a herbaceous plant with a distribution from the north-eastern part of the Eastern Cape to southern KZN. Sadly it was not - it was E. preptum. En route to look for C. nicholsonii we saw a beautiful plant with butterfly-like fruits: Acridocarpus natalitius. As we entered the forest searching for the vulnerable C. nicholsonii (a lax tree, endemic to South Africa with a KZN and Eastern Cape distribution and known from three isolated populations in Pondoland) we struggled to walk because it was slippery and muddy. Halfway in our hard walk, I remembered that I had forgotten the GPS in the car but decided I would use my phone’s GPS should I need to take points and as expected there was no network. There was, however, no need for the GPS as unfortunately we did not locate the targeted plant.

Day 2: Mbotyi and Port Grosvenor, Goss Point field trips
Having a view of waterfalls on both days was breathtaking. At Mbotyi doing more searching, we found more populations of the near-threatened Leucadendron spissifolium subsp. natalense. The area was damp and it was home to different species of orchids such as Satyrium sphaerocarpum and Satyrium trinerve

Grassland is a biome to explore, with a wide range of plants to look at in such a diverse ecosystem! With my limited skills of plant identification, I can recall, how amazed I was to see Helichrysum appendiculatum, such a stunning plant!

Our next destination was Goss Point at Port Governor and we drove for long hours on a dirt road to look for Eugenia verdoorniae (NT). On top of the current status this plant has, I think it should also be rare as it was hard to find and even after locating it we saw only one plant. This shrub is found in Pondoland scarp forest margins and on riverbanks. As scarce as this plant is, it is threatened by frequent and intense grassland fires that disturb the forest margins, hence it is Near Threatened as its habitat is being destroyed.
We were tired but still keen to locate the plant and we searched near the stream banks until we found an individual plant. We all stopped being tired and rejoiced, eyes even opened and we saw a beautiful pool and just had to drink the water. Walking back to the car we saw more plants and even specials such as Stangeria eriopus (VU) and Euphorbia flanaganii (VU), a dwarf succulent with snake-like branches that grow flat on the ground. This plant occurs in the coastal regions of the Eastern Cape and south coast of KwaZulu-Natal. We were no longer dragging our feet by now as we had our extra rewards.

During the days we spent in this beautiful place the weather was on our side, bright and sunny-with some fresh breeze. However, we experienced some rain as we drove off the Near Threatened E. verdoorniae location. I guess this was a way of proving that our two day trip in the area was a success as we managed to locate half of the species we targeted plus extras.

Our trip to this beautiful place then ended the next Monday as we drove out and made sure that we bought the delicious PSJ mangoes!
