WHY CONSERVE PREDATORS???
• Predators are indicator species,
demonstrating the health of an ecosystem
• Control numbers and health of prey species
• Valuable national resource to be protected
• Generate income through ecotourism and trophy hunting

LionLion
Lion home ranges can be anywhere between 150 and 2000 Km2
They are social, territorial animals and females often hunt together. A group of lions is capable of killing prey as large as cow or buffalo and a single lion can take down a wildebeest sized prey.
They are mainly active at night and may take animals out in the veld and from poor kraals.
They may eat the whole animal but the large bones will remain.

They are solitary, territorial animals that hunt alone. They are excellent climbers and often hide their kills in trees. Leopards are capable of killing prey as large as wildebeest but rarely take fully grown cattle.
They are usually nocturnal and will take unprotected livestock from poor kraals and out in the veld.

Except when denning, African Wild Dogs are effectively nomadic some recorded ranges have been between 420 and 1300 Km2
Wild dogs are social and live in packs. They hunt together and are capable of killing kudu sized prey. They can be a concern to farmers as can take fully grown cattle, however, they can be deterred by human presence
They are most active during the morning and the evening and more likely to cause conflict out in the veld than in the kraal.
