Photograph is of part of the South Australian section of the Australia’s extremely long Dog Fence.
The Dingo Fence or Dog Fence is a pest-exclusion fence that was built in Australia during the 1880s and finished in 1885, to keep dingoes out of the relatively fertile south-east part of the continent (where they had largely been exterminated) and protect the sheep flocks of southern Queensland.
It is one of the longest structures in the world and is the world’s longest fence.
While on an Alaskan cruise my wife chose an excursion where we flew by float plane from Ketchikan to Neets Bay in the Tongas National Forest to hopefully see some ‘wild’ black bears in their natural habitat salmon fishing.
We were not disappointed

A population of zebras undertakes the longest terrestrial migration in Africa, according to researchers who just identified the zebras’ 311-mile journey.
The discovery, published in the latest issue of the journal Oryx, provides compelling evidence that conservation efforts often require multinational coordinated support.
In this case, “The migration involves up to several thousand zebra making a return journey from the Chobe River floodplains in Namibia/Botswana to Nxai Pan National Park in Botswana,” lead author Robin Naidoo told Discovery News.
“This is a 500-km (311-mile) round trip journey along an almost direct north-south axis,” continued Naidoo, who is a senior conservation scientist at World Wildlife Fund.
The zebras spend the dry season along the Chobe River floodplains, and then when the rains begin, migrate over several weeks to the Nxai Pan National Park, where they spend several months before returning to the Chobe River floodplains.
