We climbed Inhlosane in a stiff autumn wind – the view of the changing colours of the landscape and fast-sailing clouds was incomparable, as was the huge eagle that flew straight over our heads as soon as we opened the first weissbier at the top…

There seemed to be beautiful, late-blooming flowers in every crevice and cranny of the mountain.

At Bukamanzi the spiders and beetles get odder and odder looking, but I’m quite fond of them now: This shy, translucent one hides under the rose leaves.

There’s a rather mad-looking orange and black one who turned up in the kindling basket.

Otherwise it’s been the usual Reedbuck, jackal and vervet monkeys but no sign of the resident genet or duiker in while.

A new addition is the resident snake, Sir Hiss, who I trod on one afternoon on the sunny door-mat. He streaked away like molten toffee being thrown in the air, a wild line of green, as I yelled and jumped up and down on the kitchen table for a good hour. After I described him to her, Helen Booysen thought it must have been a boomslang. She would know, after finding Barend with one whirling around his head like a kite. As snakes go it was wonderful to look at but like a mad horse I still shy away stupidly from hose-pipes/dropped tea-towels/dead sticks.

Our bit of the valley has had an especially fine blaze of autumn colour and flowers:

And as ever it’s the details that really stay with one long after the big showy scenes have faded from memory:

I think we are extraordinarily privileged to be able to observe wildlife at close quarters – often from the comfort of our favourite chair. Over the top of my computer screen, I was able to watch this gorgeous Golden Orb Web spider for a few weeks.

After a windy day, red Halleria lucida blossoms were caught in the web creating a really festive forest decoration. She is gone now.

Just outside, Hadedas built a nest in the Kiggelaria africana tree and hatched two babies. Once again, I was able to observe them at leisure, which was a treat, although the droppings made the most awful mess on the shrubs and patio beneath. Astonishing how two big chicks managed to perch on the tiny, flimsy nest. Before the fledged, they hopped from branch to branch stretching their wings.

A Midlands Autumn classic is the blaze of Leonotis leonaurus across fields and along roadsides. They are particularly spectacular this year.

Also still in flower in the long grass is the dainty, parasitic Striga bilabiata. The pinkish mauve flowers with prominent veins are borne on hairy, plum coloured stems.

Veronia natalensis (I think) is also still flowering. The dark purple contrasts beautifully with the gold, bronze and russet grasses.

Not so natural, but spectacular nonetheless, are the seed heads of Blackjacks (Bidens pilosa) along paths in the grassland.

Also in the grassland, there are lots of buck to be seen. I spotted Oribi (a group of three), Common Duiker and Reedbuck.

Relaxing in the sunshine in the middle of the road one afternoon was this beautiful Midlands Dwarf Chameleon (Bradypodion thamnobates). I moved him out of harm’s way and took some photos. Lucky me.

With much of our grass having been cut and the weather allowing for some green growth, the numbers of Reedbuck spotted have increased somewhat in recent weeks.

One of our members of staff was fortunately alerted by a scuffle in the bushes on the way to work recently and, on investigating, discovered a rather exhausted Serval (Leptailurus serval) caught in a snare. Not wanting to unnecessarily alarm the poor animal, I called on Free-Me and SA Can for assistance and they both reacted immediately. With a blanket over its head, the serval was soon calmed and the snare around its rump was quickly removed. A thorough examination surprisingly revealed no injuries whatsoever and the cat was released back into the bush. Many thanks for the prompt and expert help from these two wonderful organisations.

We have had 5 female water buck on the farm this month. They seem to hide during the day in the gum trees and come out in the early evening to drink at the dam.

An Aardvark dug this huge hole in our driveway. We filled it in but he came back several times and dug it out again. So presumably heaps of termites down this hole.

Making Sense of Roadkill

Roadkill is a widespread issue. Wendy Collinson of the Endangered Wildlife Trust shares some interesting information discovered by the EWT’s roadkill research team in the Pilanesberg National Park. Well done to all involved.


 

STRONG DATA FROM LATEST ROADKILL SURVEY

Surveys of wild animals killed by passing traffic (roadkill) have produced strong data and several recommendations. This is according to Bridgestone, which sponsored the Endangered Wildlife Trust’s (EWT) recent investigations into the issue of roadkill in the Pilanesberg National Park.

The surveys, conducted by the EWT between 21 October and 23 November 2014, consisted of on-site investigation of roadkill as well as questionnaires completed by 302 visitors to the park. Of the 120 roadkill observed by the roadkill research team, 62 were amphibians, 27 were reptiles, 20 were birds, ten were mammals and one was not identifiable.

Vehicle numbers were monitored by the use of traffic counting devices. However, the roadkill research team soon discovered that elephants had taken a liking to the devices and damaged them. Drawing on previous research which has shown that elephants dislike the smell of chilli pepper, the team then applied a daily coating of chilli pepper and oil onto the counters. The traffic counting devices were then protected from further damage.

One of the most interesting aspects of the project was the role of speed in contributing to roadkill. “More than 95% of respondents to the questionnaire survey believe that speed is the sole cause of roadkill. Our aim was to investigate this issue in more detail,” said the EWT’s Wildlife and Roads Project Executant, Wendy Collinson.

Compliance with park speed limits was found to be reasonably high, with 72% of the 6,981 vehicles monitored driving at or below the speed limits. “We postulated that roadkills were likely to occur because drivers were either unaware of their surroundings or travelling too fast to be able to avoid collisions. To investigate these factors we monitored a sample of 201 vehicles and nearly 70% of the drivers were observed to not be looking at the road, but rather scanning the bush for wildlife”, said Collinson. “This suggests that many roadkills in national parks happen because of the expectation that animals are to be found in the habitat alongside the road, rather than on the road itself”, she added.

The same sample of vehicles was used to investigate the role of speed in determining rates of roadkill. The research team placed three fake animals on the road, and recorded how many times each roadkill was hit (for a total possible hit count of 603 roadkill). We also recorded how fast each vehicle was driving, assigning them to three speed categories of <20km/hr, 21-40km/hr and >40km/hr. We found no significant difference between hit rates of drivers in each of the speed categories, with approximately 50% of drivers hitting the fake roadkill across the board.

“From our survey, it seems that observation levels of the driver, rather than the speed of the vehicle, is the key factor in preventing roadkills,” Collinson commented. “One of our recommendations from the latest roadkill survey is that a driver awareness campaign be launched in parks to make drivers more aware of animals on the roads themselves,” Collinson commented.

Collinson also said she was concerned about the low awareness levels of roadkills among park visitors. “Of the 284 respondents who had visited a park previously, only 2.8% had noticed roadkill, with 6.3% noticing a roadkill on their current visit,” she explained.

Steven Dell, Pilanesberg National Park’s Field Ecologist remarked, “despite the use of road signs both at the park gates and within the park as well as efforts to raise public awareness of roadkill, roadkill still occurs. This project was extremely beneficial to the park as it has assisted in identifying the cause for roadkill and will enable us to focus our future public awareness efforts.”

Bridgestone PR Manager, Desirée van Niekerk, said the results of the latest roadkill survey had proved as fascinating as ever. “Bridgestone has been involved with the roadkill project for three years now, and we applaud Wendy and her team’s contribution to both road safety and wildlife protection,” she said. “We hope these latest findings will soon be used to improve the quality of the experience of park visitors and safeguard the animals in these protected areas,” she concluded.

The next stage of the project will shortly commence in Addo Elephant National Park.

The EWT’s Wildlife and Roads Project in Pilanesberg was supported by Bridgestone SA, Arrow Bulk Logistics, Pilanesberg National Park, Copenhagen Zoo, Mikros Traffic Monitoring and Africa:Live.
