A private farm in the Umtumvuna - 21 April 2022

 

Some days are days that have hiccups and minor challenges that come one’s way but they can be overcome with humour, calmness and a lot of cheery songs in the car as one navigates to find a place to botanise as Simon had joined us and with his love for trees a forest was on our radar.  With no access into closed gates into the Umtumvuna Reserve we ended up on a private farm near Red Desert and Beaver Creek. 

With forests comes spiders, plentiful and large in all shapes and sizes.  The stream ran through the giant trees and Anne and Tracy skipped ahead to ring bark alien invasives whilst Dorothy taught us how to identify trees.  We nibbled on the fruits of Cryptocarya wyliei and then browsed on the Embeilia ruminata which was an acquired taste, a little like Portulacaria afra perhaps - sour!  After nestling down in a cluster of trees in the shade to have our lunch we set off again up into the grass land where we found ourselves rather bogged down to say the least.  The earth was so wet and squelchy that had one been a pig one would have been very happy and at home. There on the slopes we found the endangered Helichrysum pannosum, not spectacular in the least.  The Morea stricta literally opened up their candle like heads at two o-clock to show their faces in the late afternoon sun.  We dipped back into the forest, where the boulders were huge and the trees were so old and tall.  Huge Encephalartos natalensis and Stangeria eriopus grew here. 

We had all left in good spirits and found ourselves back in the car singing away.  


Stangeria eriopus
ZAMIACEAE



Olea capensis subsp. macrocarpa
OLEACEAE



Encephalartos natalensis - Giant Cycad
ZAMIACEAE 
Near Threatened A2ad

Justification
This species has declined in some parts of its range. The overall population decline is estimated to be <30% over the past 60 years, based on repeat photographs and visits to subpopulations. It could be listed as Vulnerable if overall population numbers drop below 10 000 (C1) or if the extent of decline increases from the current level up to 30% or higher.

Moraea stricta
IRIDACEAE

This Moraea opened up twenty minutes before its scheduled time.  When it's 2 o'clock they open up and show their beautiful faces.



Helichrysum pannosum
ASTERACEAE
Endangered A2c

Justification:  A population reduction of at least 50% is estimated based on 55.4% habitat loss in the past 90 years, mainly due to cultivation of sugarcane and other crops, urban and coastal development and alien plant invasion, and it is suspected to be locally extinct north of Durban due to more than 90% habitat loss in that part of its range. The generation length of this resprouting grassland forb is estimated to be 30 years. Although still fairly common in remaining suitable habitat, this species is expected to continue to decline as a result of ongoing habitat loss and degradation. - Sanbi's Red List
