Points of
Interest
A Tabernaemontana ventricosa
- Forest toad tree
This is usually a smaller tree of
the forest understorey. It has opposite leaves, sticky white sap, and sweetly
smelling, white star-shaped flowers that often fall to the forest floor. The
conspicuous toad-like fruit appears from February to July.
B Rauvolfia caffra - Quinine
Tree
This is one of the tallest forest
trees. Leaves have translucent veins and are arranged in fours. Milky latex
exudes from broken off leaves and twigs. The bark contains the drug reserpine,
which is used as a tranquiliser and to treat high blood pressure.
C Dichrostachys cinerea -
Sickle bush
A common small tree or shrub of
bushveld, in summer it has beautiful pink and yellow flowers. It is heavily used
for magical and medicinal purposes throughout Africa.
D Commiphora harveyi -
Bronze paper commiphora
This small to medium size tree is
usually associated with valley bush and rock outcrops. It is instantly
recognisable by its smooth, dark green bark, peeling off in thin, reddish-bronze
sheets.
E Ferns
The fern that you see here is a
species of Nephrolepis, which has escaped from local gardens and become a
problem in many parts of the reserve, as it displaces indigenous vegetation.
Other problem plants are Lantana camara, Chromelaena odorata and Solanum
mauritianum.
F Cycads
Occurring in rocky, forested parts
of the reserve is the Forest Cycad Encephalartos villosus. The leaves are rigid,
palm-like and 1 to 2,5 metres long. The leaflets are toothed. At certain times
of the year male and female plants produce cones. The female cone ripens
yellow-orange, where it is conspicuous in forest shade. Hornbills and loeries
eat the bright red seeds.
The Natal Cycad Encephalartos
natalensis, with a stem of up to 3 or 4 metres, grows only on inaccessible rock
faces, where it is safe from thieves. Specimens of the Natal Cycad have also
been planted at the gate entrance to the Interpretative Centre, opposite the
Bridle Road picnic site.
G Species of Streptocarpus
This plant is described in the
introductory chapter. It flowers in December and January.
H Rock dassie shelter
The common dassie in the reserve is
the Rock Dassie. Their strong smelling communal latrines are often found along
the base of the gorges.
I Tragelaphus scriptus -
Bushbuck
The male of this handsome stands 80
cm at the shoulder and is 40 kg in mass. Females are smaller and lack horns.
Both sexes utter a loud, dog-like
bark as an alarm call, though the bark of the male is louder. They are shy and
retiring, and so are not often seen.
In dry winter months they occur
close to water and have a home range of less than half a hectare. This increases
to about 6 hectares in the summer.

J Philantomba monticola -
Blue Duiker
This is the smallest of the African
antelopes. It stands at 30 cm at the shoulder and has a mass of only about 4 kg.
It occurs only in dense forest and is rare in South Africa.
Both sexes have tiny spike-like
horns. Their coats are a dark, smoky-grey with a bluish sheen, hence the common
name.
Like Bushbuck, the Blue Duiker is a
browser. It feeds on low-growing shoots, leaves and fallen fruit.

K Cephalophus natalensis -
Red Duiker
Standing at 43 cm at the shoulder,
and with a mass of about 14kg, the Red Duiker is another rare forest antelope,
which has disappeared from most of its former range in southern KwaZulu-Natal.
Both sexes have short straight horns
and are deep chestnut in colour. Their feeding habits are similar to those of
Blue Duiker.
L Sylvicarpa grimmia -
Common Duiker
Standing about 50 cm at the shoulder
and with a mass of 15-20 kg, the Common Duiker occurs in a wide range of
habitats, from long grass to scrub and edge of forest. Like the Red Duiker it is
a browser.
The males have short, straight
horns.
M Atilax paludinosus - Water
Mongoose
These small predators are about 85
cm long and have a mass of 3,4 kg. They are mainly active in the hours after
dawn and before dusk.
They have fine elongated toes on
each foot, and their spoor is often seen in the mud alongside streams and
rivers.
Frogs and crabs are favourite foods,
but they also eat fish, rodents and insects.

N Open grassland
Containing by far the greatest
number of plant species are the grasslands on the gorge plateau. These are mere
fragments of what existed before suburbia. In the late summer, hundreds of
purple-flowering Watsonia are an unforgettable sight.
The grasslands are managed to
maintain diversity and prevent scrub and forest encroachment. The reserve is
therefore divided into blocks that are burnt on a rotational basis.
O Spiders
Along this section of the trail one
is likely to find the unusual looking kite spider. They come in various bright,
shiny colours with sharp projections to protect themselves from birds.

P Antlions.
In this soft sandy area look out for
a number of conical indentations in the soil. Those are the lairs of the antlion
larvae.
The antlion conceals itself in the
bottom of the cone and waits for passing insects to fall in the hole. The soft
sides make it difficult for an insect to escape and it is soon drawn underground
to be devoured.
The mature antlion resembles a
dragonfly except that it is not as brightly coloured, has long prominent
antennae and is a poor flier. Spend some time here and see if you can witness a
"kill".
Q Lichens
ichens are plants that consist of an
alga and a fungus. The fungus forms the structure of the lichen and its rhizoids
(primitive root-like structures) attach the lichen to the rock surface. The alga
provides food by photosynthesis, while the fungus provides shelter, minerals and
water.
Acid produced by lichens plays an
important part in breaking rocks down. Lichens grow very slowly in arid
environments, less than one millimetre a year. Some are thousands of years old
and rival the oldest plants.
Because litchens take in minerals
from the air they are highly vulnerable to pollutants such as sulphur dioxide,
which kills all but hardy species. The number and type of lichens in an area
therefore give a good indication of air quality.
R Crowned Eagles
This majestic raptor is unmistakable
in flight with its short broad wings and long tail, both heavily barred. If
flying low enough, its rufous underwing coverts can be seen. It has an occipital
crest which is only seen if raised when the eagle is excited, or by wind. When
perched it can be easily overlooked as its dark blotched body provides perfect
camouflage in the dappled light of its forest habitat. It is very vocal,
particularly when performing its undulating display flight high above the
forest.
The Crowned Eagle is the most
powerful of the African eagles. It is able to subdue prey many times its own
weight, using the very powerful talons.
Their main diet consists of dassies,
antelope and monkeys. A search below one nest in the KKNR revealed the skulls of
18 dassies and 2 mongooses.
There are at least two pairs present
in the KKNR and they are able to breed annually. A well known nest in the
reserve has been occupied by crowned eagles for about 40 years, and has been
rebuilt many times.

S Equus burchelli -
Burchell’s Zebra
The Zebra found in this reserve can
be easily distinguished from the other two species found in South Africa by the
yellow to greyish coloured shadow stripes between the black stripes.
The zebra will normally be seen in a
group which will consist of a dominant male, the females and their young. The
adults will defend the young by kicking and biting and will move between the
perceived threat and the juveniles.These animals are grazers and prefer areas
with short grass.The reason for the zebra’s stripes has been debated for a
long time. One theory is that the stripes are good for camouflage in certain
light conditions, another is that the mass of stripes when the herd is fleeing
an attack will confuse the predator. These theories are not totally
satisfactory.
Just like the fingerprints on your
finger, no two zebra’s stripes are ever the same and can be used as a system
of identification.
