Come bioblitz with us in the Overberg!

The Great Southern Bioblitz (GSB) is around the corner. Everyone is waiting for our events to be announced. The aim is to make as many as possible observations from 28 to 31 October of flora in our diverse Fynbos and also of pollinators, birds, mammals, reptiles, fungi and marine life on our shores. We want to share with the world the Overberg's special place in the Cape Floristic Region.

It is easy to take part, you need a love of nature and curiosity about species occurring naturally in the wild. You must also be willing to use iNaturalist and have an internet connection.

Download the free iNaturalist app and head out for a walk. Explore your local area, go hiking, discover wild flowers and wildlife on road verges, vacant stands and the beach. Look up into the sky and see what is flying past or look under rocks and in the soil to see what wriggles there. Take photos with a camera or phone.

Tips for taking photos:

  • Try take clear photos, it helps experts with identifications
  • Take photos from different angles
  • Plants: take photos of flowers, leaves and fruits or seeds, growth habit and habitat
  • Insects: as much as possible of the whole body. Take from above and from the side. Extra detail like antennae, eyes and legs also help. Look at what your bug is sitting on and what he is doing.

Then upload your photos using the app or website. In many ways the website version of iNaturalist is more satisfying because it has more functionality.

To learn more about iNaturalist and the GSB join the popular weekly online iNaturalist tutorial sessions on Teams. For login details: send an email to crew@sanbi.org.za

Quest #1 Overberg - where is the Horny Leaffig?

We please urgently need data for Skiatophytum skiatophytoides Horny Leaffig
see
https://www.inaturalist.org/taxa/915620-Skiatophytum-skiatophytoides

We are specifically looking for good pictures of flowers and fruit. And more records.

See the map tab on the link above for iNaturalist localities.
See the phenology graph for the ideal season: October-November.

Bredasdorp District:

  • Brandfontein., Brandfontein nr coast, track from Brandfontein to Aasfontein
  • Ratelriver
  • Soetendalsvlei area, Soetendalsvallei - roadside w of Jubilee Hill
  • Springfield
  • Baardskeerdesbos at homestead.(Heidehof farm)
  • Franschekraal flats
  • Gansbaai Road, 2 miles W of Agulhas-Bredasdorp road

We also want to know if there are any records of its sister species Skiatophytum tripolium https://www.inaturalist.org/taxa/594561-Skiatophytum-tripolium Flat Leaffig
south of Stanford. There are no records in the Pretoria herbarium for Agulhas at all, but iNaturalist records appear to be this from Phiilipskop and north of Papiesvlei just e of Stanford.

More details here:
https://www.inaturalist.org/observations/16724471
Basically we want to see if there is an easily visible difference in the fruit, and how close these two species get to one another. Our hypothesis is that they will not overlap in distribution.

You can help. Please visit these areas and look for these species.
Dont forget to record everything else of interest that you might observe as well for the Great Southern Bioblitz.

Quest #2a Surveying the False Heath

We need some help please in surveying the False Heaths historical distributions.

see https://www.inaturalist.org/projects/audouinia-capitata-false-heath

Although it is not the ideal season (Jun-Sept is best), we can still try, and get observations of surrounding species as well.
Details of sites that we need data from can be found here:

https://www.inaturalist.org/posts/71013-progress-with-localities

Off the Peninsula, the records that need attention are:
Please count and record your counts using the RedList (s Afr) project and record any threats.

  • Sir Lowries Pass (De Jonge 1896) Cape Town - This population has not been seen since. But as the current Pass was opened in 1830, this is likely to be the current pass, and not the old vertical, oxwaggon, Gantou Pass. However, it is likely to be near the summit and not the west ascent, and possible the east plateau, in which case these were probably wiped out by the pine plantations of the 1900s.
    Please be aware of security issues.

  • Houhoek Pass, Botrivier. Only picnic place in the pass as you drive to Grabouw to Botrivier. Altitude.: ±340m. (de Lange 1996, Forester 1996) Overberg This seems a low hanging fruit with a precise locality. There are lots of specials here, so please keep an eye out for anything in flower in the area.
  • Hemel en Aarde.(Ecklon 1800s); Farm of old Moravian missionary.(De Lange 1987)Overstrand Another low hanging fruit with a precise locality. Please arrange access beforehand. And look for other specials here too: basically anything in flower.
