|[Note Guidelines] Photographer's Note|
|The elephant and calf shown here were photographed in the Addo Park famous for its elephant population. What is especially interesting in this area is that the park has 5 seperate types of vegetation. The largest is the Arid Thicket type described below from the National Parks board website.|
is found in the interior with succulents being dominant and a small woody component.
• Adapted to withstand the valley's temperature variations from 7 �C to over 40 �C and unpredictable rainfall (varies between 200mm - 600mm) occurring at any time of the year.
• Few grasses and few large trees. Vegetation varied in height, most shrubs up to 3-4 metres. Taller plants are euphorbias and aloes. Understorey of dwarf succulents and bulbous plants.
• Adaptations to survive severe environmental conditions include:
• Leaves small/absent/leathery/unpalatable.
• Water stored in succulent stems/leaves.
• Thorns and/or poisonous/bitter sap for protection from browsers.
• Ability to tolerate disturbance by trampling animals - drop, reroot quickly and form new plants.
• Underground storage organs which sprout quickly after rains e.g. bulbs, corms, rootstock.
• Flowering not restricted to specific season but after good rains.
• Pollinated by birds and most fruit dispersed by birds.
• Mosaics of vegetation are created in thicket by geological processes, grazing by megaherbivores and by fire.
• 48 species of medium to large mammals occur in this biome (26 herbivores, 16 carnivores, 4 omnivores and 2 insectivores).
• Little is known about the insect species associated with Subtropical Thicket but for every one plant species, there are between 8 and 35 organisms dependent on this species.
• Thicket is crucial in maintaining life support systems. It holds soil well and it keeps rivers clean by holding the very fine soil found on steep river banks. This is important in riverine and estuarine ecosystems.
• - Lichens and mosses play an important role in this biome, providing good ground cover and breaking the energy of raindrops, allowing them to penetrate the soil effectively.
• - Many thicket species have great horticultural potential. Some have already been widely exploited e.g. the strelitzia - a symbol on SA coins, hailed as the emblem of Las Vegas (while actually endemic to SA!); pelargoniums from which all hybrids are descended are widely exploited in European countries (but originally from SA).
• - The Subtropical Thicket biome faces extreme threat from overgrazing, bushclearing for agriculture and inadequate representation in reserves.

Awesome content of course.
Have you tried 'sharpening' in pp workflow?
I checked the Addo park. I saw at the SAN sites, there's also black rhino to spot. I wonder if you were able to do that?

Hi Robin. You have take a picture of the Elephant with its young one animal which i like so much. I love the way the baby looks so old before it starts it life. The mother looks so big againt the calf. good detail in the skin with warm natural colours. i would have loved to have sen this in the wild. TFS.
Have a nice weekend.

very lovely image
A really lovely photo. I agree with Annick that it needs a little sharpening and then it will be perfect.
