New herbicide for pompom weed

FOLIAR APPLICATION of Plenum to Pompom weed

  • Use only on actively growing plants with full leaf cover
  • Apply as a full cover spray to leaves and stems to the point of spray solution run-off.
  • Do not apply to foliage wet from rain or dew etc.
  • Avoid spray drift onto non-target plants.
  • Avoid fine droplet size. Use a knapsack sprayer with a solid cone nozzle (eg. Spraying systems TG-1, Delavan CE 1 or equivalent type) that will ensure an even coverage ofthe target area. Maintain a constant pressure of between 200 – 250 kPa. Maintain a distance of approximately 50 cm from the target for best coverage.
  • Rain 3 hours after application will have no effect on efficacy provided the spray has dried on the target plants.
  • Prevent drift of spray mist onto desirable plants.
  • Apply to actively growing plants. Apply until the point of run-off.
  • Plants too high for a good cover spray should be slashed and the regrowth sprayed when not less than 0,5 m high.
  • In the event of any regrowth after application, a follow-up spray should be carried out.


There is no better time to deal with Pom Pom

We have had a good soaking rain.  And large parts of the landscape burned during the winter.  The pom pom is already growing, and can easily be spotted in the burnt veld - so grab the opportunity and get NOW, well before the flowers start.


Report to DWIP on Initiatives to Control Alien Invasive Plants

To date the RNC has focussed almost exclusively on Pompom and Verbena. Other alien invasive pants like Seringa, Lantana, and invasive Cacti are present but have not been addressed in any meaningful way. The RNC controls Pompon and Verbena infestation at the same time, both alien plants have a strong foothold in the conservancy; they are often found together, have overlapping seasons and can be controlled with the same pesticides.


Found in the Veld

While driving home recently I was confronted by a magnificent snouted cobra.  It stood swaying in the middle of the track, seeming to challenge me as I stopped to grab my camera.  Then it suddenly shot off into the long grass and to my surprise, another cobra slithered over the road after it.

I regularly cycle through the Schurveberg area and found these clear tracks in a patch of dried clay.  After asking verious experts, they concur that these are brown hyena tracks “due to the difference in size of the front and back spoor”. My cell gives an indication of size.  What is really amazing is that the location of these tracks is within 700m of the first house in a suburb of Erasmia.

Editor's note:  The brown hyena spotted by Lee Dormer in Doornrandje (VeldTalk 51) was found dead next to the R511 on 23 July.  It must have been hit by a vehicle.

I found this fascinating pattern on the trunk of a Karee tree severely burnt in a veld fire.  Karees are hardy and this one will probably survive but the damage done by fires every year is heart-breaking.

Hierdie yslike groot skilpad het naby ons huis oor die pad geloop.  Nog ’n bewys van die wonderlike natuur en die verskeidenheid van diere en inseklewe om ons.  Gelukkig is daar min verkeer op ons pad maar watter kans het sulke skilpaaie wanneer ons velde so brand in die winter?

Editor's note: The winter veld fires hit the Conservancy hard this year.  While some fires got out of hand when fire-breaking was attempted during the day, others were deliberately set alight at night.  Those residents who regularly respond to fight fires report a considerable cost in cut tyres, damaged vehicles and firegreens.

Students take to the Veld

If rocks could talk, the Conservancy would be an entire encyclopaedia.  A Rockipedia!  The local rock formations have fascinated academics, gold diggers, stone masons and ordinary citizens for decades.


Scorpion Walk - 2/5/2010

The very entertaining scorpion fundi, Jonathan Leeming, will lead another scorpion walk in the Conservancy on Sunday 2 May. 
Jonathan's accounts of his life with scorpions are very funny and for those who don't care about a closer encounter with these creatures, it's worth joining the walk just to hear Jonathan's stories!

On top of that, Professor Pink and the Knock Knock TV team will be filming again.  The Knock Knock programme on our Spider Walk was screened twice this week on SABC3.

Bordering the Cradle of Humankind, north of the Lanseria Airport and with the Magaliesberg Mountain range dominating the northern horizon, find the Rhenosterspruit Nature Conservancy.

The Conservancy lies centrally between Pretoria, Johannesburg and the West Rand, and is a largely unspoilt, natural area. The region, including the Cradle of Humankind, is a valuable link through to the Magaliesberg range, and therefore an important link in a conservation corridor for species migration.


Egoli Granite Grassland - what is it?

There has been much excitement about Egoli Granite Grassland (EGG) and the opportunity for formal conservation that has opened up in the RNC.  But what is EGG?  Where does it grow? What makes it special?


A night time visitor

A little fellow came calling in Doornandje...

Hedgehogs curl up into a tight ball when disturbed.  They are mainly active at night, and sometimes come out in the day at the start of the rainy season.   They hibernate between May and July - seeing this creature in April was fortunate.

They eat insects, millipedes, mice, lizards, earthworms and some fruits.  Many areas have reported a decline in hedgehog numbers, including the Conservancy.  The creatures are often captured by humans.  They are also affected by long periods of drought.

Hedgehogs have a conservation status of "near threatened". That means, close to qualifying for or is likely to qualify for a threatened category in the near future.

Scorpion Walk

A great outing with the creepy-crawlies was had under the expert eye of one of South Africa's leading experts, Jonathan Leeming.
