CONSERVATION
Assegaai Conservancy
Sustainable utilization begins with the conservation of the soil, water and plant life, in order to have healthy animals, one has to have healthy soil, water and plants.
Conservation of Nature
An Endangered (EN) species is a species which has been categorized by the International Union for Conservation of Nature (IUCN) Red List as likely to become extinct. “Endangered” is the second most severe conservation status for wild populations in the IUCN’s schema after Critically Endangered (CR).
The conservation status of a species indicates the likelihood that it will become extinct. Many factors are considered when assessing the conservation status of a species; e.g., such statistics as the number remaining, the overall increase or decrease in the population over time, breeding success rates, or known threats. The IUCN Red List of Threatened Species is the best-known worldwide conservation status listing and ranking system. The list of endangered species in South Africa includes, but is not limited to, the following animals:

Oribi grow to around 92–110 cm (36 to 43 in) in length, with a shoulder height of 50–66 cm (20 to 26 in) and weigh an average of 12–22 kg (26 to 49 lb). They can run at speeds of up to 40–50 km/h (25–31 mph). In captivity, they have lifespans of up to 14 years.
The back and upper chest is yellow to orange-brown. The chin, throat, chest, belly, and rump are white. The tail is short and bushy, the upper side black or dark brown, and the under surface white. The white, crescent-shaped band of fur above the eye helps to distinguish this species from other similar-looking antelope. Below each ear is a large, round, black, glandular patch, the nostrils are prominently red, and on the sides of the face are vertical creases that house the preorbital glands. These glands produce an odorous secretion used to mark the oribi’s territory. Only males grow horns, which are slender and upright, ridged to about halfway up, the ends being smooth and pointed, with some of length 19 cm (7.5 in) being recorded.
Threats and conservation
Oribi populations in many areas are threatened by human activities, such as:
- Habitat destruction – Grasslands are lost to expanding settlement, commercial forestry, intensive commercial farming, grassland degradation due to overstocking, poor use of fire, erosion and mining.
- Illegal hunting – Trapping with snares and hunting with dogs are serious threats, and has led to the demise of many oribi populations in South Africa.
- Inappropriate management – In many areas where oribi are present, farm management practices (impenetrable fences, poor burning practices, poor veld management, domestic dogs) do not allow oribi to coexist. Sport hunting of oribi at unsustainable levels also threaten their survival.
Oribi occur in several protected areas and are the subject of a WWF Species Project. This project aims to track captive-bred oribi after their release into appropriate habitat to research their home ranges and habitat preferences. The long-term aim of the project is to establish viable wild populations from captive-bred stock.
The bontebok is a tall, medium-sized antelope. They typically stand 80 to 100 cm (31 to 39 in) high at the shoulder and measure 120 to 210 cm (47 to 83 in) along the head and body. The tail can range from 30 to 60 cm (12 to 24 in). Body mass can vary from 50 to 155 kg (110 to 342 lb). Males are slightly larger and noticeably heavier than females. The bontebok is a chocolate brown colour, with a white underside and a white stripe from the forehead to the tip of the nose, although there is a brown stripe across the white near the eyes in most blesbok. The bontebok also has a distinctive white patch around its tail (hence the Latin name), while this patch is light brown/tan in blesbok. The horns of bontebok are lyre-shaped and clearly ringed. They are found in both sexes and can reach a length of half a metre.
Threats
Bontebok were once extensively killed as pests, and were reduced to a wild population of just 17 animals, but the species has since recovered. Blesbok are extinct in their natural habitat, but they have increased in population to the point where they are now very abundant and avidly farmed, because they are popular quarry for hunters and are easy to sustain.
Fauna & Flora
Spekboom
The bright green fleshy leaves have an egg like shape. As the tree ages the colour turn yellowish. The English name, Elephant Food, originates from the habit of elephants to eat the top shoots of the “trees”, causing the plants to grow and spread horizontally.
Spekboom has an exceptional ability to take big quantities of carbon dioxide out of the air and convert it oxygen. Ongoing research shows that 1ha of Spekboom can covert carbon dioxide to an average of 4.2t of oxygen per year. This makes South Africa very popular on the international carbon dioxide sequestration commercial market
Wild Fig Tree
The knobbly fig is generally evergreen but may be partially deciduous during drought. It is usually without aerial roots, and contains milky latex. The bark is grey to dark grey, smooth, uneven and does not peel off. The main stem is usually short, forming branches low down and bearing numerous unbranched fruiting spurs.
The branches are slightly flaking and hairless. The fruits are 40 mm, hairless, and dark purple with yellow-green dots when ripe, and are borne singly or up to four in a cluster. The fruits are edible but unpleasant.
Family Activity
In the afternoon the family or group can then assist in the eradication process by planting ‘good’ trees such as spekboom, olive trees, plum trees, wild fig, etc. This will provide the family or group with valuable information on the eradication process in the area and give them an opportunity to make a difference in the eco system through the planting of the good, indigenous species.
Every tree planted by a family will be a recognised family donation and retain a unique place with associated GPS points in the Family Tree Book of Record. Future visits will include the viewing of the growth of the tree.
