I really appreciate you coming back and taking note of concerns Paul, this shows that Sanparks don't just decide unilaterally as they have been accuse of doing
With a corridor open I can see the need for a fence (spit), I have on a few occasions witnessed stupid behaviour by visitors towards some of the large herbivores that come right in to the camp. My question is what other benefit would be had by opening a corridor? I know that the Kwaggasvlakte is on sweet veld and is home to quite a few herbivores as well as the smaller predators like jackal and gennet. The isolation that these animals have lived in would be a disadvantage when the fences are dropped as the large predators would have a party amongst the "ignorant" plains animals and elephant will move down to the nutrient rich plains vegetation placing more stress on it as well.
Marakele is a park with a different feel to it. If you expect a mini Kruger you will be disappointed like the original poster. Camping in Bontle you don't wake up well before gate time to be the first out, no, you rise as the sun rises and sit on your favorite camp chair with a steaming cup of coffee while the game comes down to the waterhole and parades for you. there are no road blocks at sightings just fellow campers bringing a chair to sit and enjoy nature in its naked best. The best part of this little gem is not that it is a big 5 park but the serenity and beauty of nature that it has. Going to the big 5 side is not so much to see a predator but to get to the top of the mountain 1,1 km above Bontle and have a view of what one forumite described as a garden of mountains, if you are lucky and the time coincides with the thermals being just right you can see the biggest breeding colony of vultures rising from their roosting sites and flying over the top at treetop height to forage and with a few alpine bird species this is a birder's treat. If you had kept your eyes open en route you might have been lucky to see the shy reedbuck or the elusive sable but regardless of that the mountains will be unforgettable.
Would having a few predators on the plains justify the loss of character of Bontle camp? If the fences are dropped on the road they will unfortunately have to be erected around the camp. As for the question of what species to cater for with the fence, easy, humans.
