Frond

Tree ferns are ferns that grow with a trunk elevating the fronds above ground level. Tree ferns are found growing in tropical and subtropical areas, including cool to temperate rainforests. Like all ferns, tree ferns reproduce by means of spores formed on the undersides of the fronds. The fronds of tree ferns are usually very large and multiple-pinnate. Their trunk is actually a vertical and modified rhizome and woody tissue is absent. To add strength, there are deposits of lignin in the cell walls and the lower part of the stem is reinforced with thick, interlocking mats of tiny roots. Tree ferns often fall over in the wild, yet manage to re-root from this new prostrate position and begin new vertical growth. It is not certain the exact number of species of tree ferns there are, but it may be closer to 600-700 species. Many species have become extinct in the last century as forest habitats have come under pressure from human intervention. Info source: https://en.wikipedia.org/wiki/Tree_fern

Adult hippos move at speeds up to 8 km/h (5 mph) in water; typically resurfacing to breathe every three to five minutes. The young have to breathe every two to three minutes. The process of surfacing and breathing is subconscious: a hippo sleeping underwater will rise and breathe without waking up. A hippo closes its nostrils when it submerges into the water. As with fish and turtles on a coral reef, hippos occasionally visit cleaning stations and signal, by opening their mouths wide, their readiness for being cleaned of parasites by certain species of fishes. This is an example of mutualism in which the hippo benefits from the cleaning, while the fish receive food. Although hippos lie close to each other, they do not seem to form social bonds except between mothers and daughters, and they are not social animals. The reason they huddle close together is unknown. Hippopotamuses are territorial only in water, where a bull presides over a small stretch of river, on average 250 m (270 yds) in length, and containing 10 females. The largest pods can contain over 100 hippos.

There are 3 main layers of rock in Golden Gate Highlands National Park, the characteristics of which have lead to the famous cliff formations present in the park today. The red layer was created 200 million years ago when swampy rivers deposited the mud-like sediment. 196 million years ago, the area dried up and became a desert, resulting in the yellow sandstone deposits. From 160-190 million years ago, volcanic activity capped the area with a basalt layer. The rivers and streams in the park have carved the rocks into their present formations. The name ’Golden Gate’ originates from the two cliffs that face each other on either side of the road: at sunset, the yellow sandstone becomes a rich gold colour. And those black marks?All around the park you can see black stripes on the rock, even long after it has rained. These are areas where water seeps out of the rocks. Minerals from the top basalt layer (manganese dioxide) are carried in the water and these stain the rocks black. The water enables organisms like algae and moss to live on the rock as well.
