Evan is our American volunteer, who will be working with us for the year.

He is photographing as many plants and animals in renosterveld as he can over this period and uploading many of these images onto I-Spot (www.ispot.org.za) for adding to the central database, as well as getting assistance with IDs.

The idea is that we develop our renosterveld database in a way that will guide us for future conservation action in the Overberg's lowlands.

In our spring surveys, we have found new populations of several threatened species, which is very exciting!!
 

For example, this is Gladiolus vandermerwei, Endangered.
 

Then there is Moraea tricolor, a real little gem...

 

And this wonderful little Klein Karoo (Robertson) Chameleon...

ABSTRACT

Quartz fields are islands of distinct vegetation in southern Africa. Such habitats differ from surrounding shale substrate in geomorphological and climatic attributes, and are dominated by a predominantly succulent flora with between 14% and 91% endemism. Previous studies have identified and surveyed quartz fields within the Succulent Karoo biome, but little is known about the Overberg quartz–silcrete fields located in the Renosterveld vegetation (Fynbos biome). This study maps the occurrence of quartz–silcrete fields in the Overberg (Eastern and Central Rûens Shale Renosterveld) and investigates if such fields support distinct vegetation compared with surrounding shales. Forty-seven plant species were recorded, 19 of which are endemic to the quartz–silcrete patches, including several newly discovered species in vascular plant families Cyperaceae (Ficinia), Iridaceae (Hesperantha) and Fabaceae (Aspalathus, Otholobium, Polhillia, Xiphotheca).

Five species among these are described in this paper: Aspalathus quartzicola C.H.Stirt. & Muasya, Aspalathus microlithica C.H.Stirt. & Muasya, Ficinia overbergensis Muasya & C.H.Stirt., Otholobium curtisiae C.H.Stirt. & Muasya, and Polhillia curtisiae C.H.Stirt. & Muasya. Detailed floristic composition of 25 quartz fields is surveyed,together with their conservation status. The Overberg Quartzveld is a critically endangered vegetation type that is the sole locality for 18 Red Listed plant species; which include seven new taxa. It is a distinct vegetation unit embedded within Rûens Shale Renosterveld in the eastern Overberg region of South Africa. These quartz patches have been overlooked in the past and we emphasize the need for further research and conservation attention of these habitats.

Camera traps in renosterveld

We have started setting out camera traps in renosterveld remnants and here is what we have found so far.... caracal, African Wild Cat, Egyptian Mongoose (also known as Large Grey Mongoose) and Porcupine. This is all from one site. Watch this space for more, as we have just set two cameras up on a new farm...

OLCT RECEIVES MAZDA WILDLIFE VEHICLE!

Thank you, Mazda Wildlife Fund, for recognising the importance of the work we are doing and providing us with a loaned project vehicle... a beautiful BT50 double cab 2X4 Mazda bakkie! We are thrilled with this acknowledgement so early on in our development and believe with this platform, we can go from strength to strength!

Going, going, gone: Overberg bulb naming rights sold

The right to name a rare Overberg bulb has been sold for £29,200 in the United Kingdom. The naming of the newly-discovered Hesperantha species was auctioned on 31 October. Proceeds of the auction will go to the Overberg Lowlands Conservation Trust (OLCT), an Agulhas Biodiversity Initiative partner.

The auction was arranged through Fauna and Flora International (FFI). The starting price was £500, and bidders were able to bid online. Bidding closed on Wednesday night at the FFI Annual General Meeting at the Royal Geographical Society held in London.

The rare bulb was discovered in the Overberg by the OLCT Director Odette Curtis late last year. Curtis, who attended the auction, said she was “thrilled” with the outcome.

Funds raised will now be used in supporting conservation of lowland renosterveld. Renosterveld is critically endangered, with only four to six percent remaining in South Africa. It is threatened by invasive alien plants, overgrazing, veld fragmentation and in some cases by illegal ploughing.

 

The winning bidder will also receive a painting of the beautiful iris, and a bronze casting of the flower.
