Habitat Loss

What Is Habitat Loss?

Word of the Week


Habitat Fragmentation

Habitat fragmentation occurs when an environment is divided into smaller, separated sections (or fragments). Habitat fragmentation reduces the total size of available habitat and makes it harder for animals to travel.


The construction of roads, farms, and cities can cause habitat fragmentation.

Cheetah

Acinonyx jubatus

Cheetahs are the fastest land animals in the world. Would you believe the world's fastest land animal has trouble moving around their environment? Well, it's true!


Cheetahs live on the African savanna. Their spotted coat keeps them hidden in tall, dry grasses so they can sneak up on prey like gazelles, springbok, rabbits, and more. Once their prey comes close enough, cheetahs begin the chase. They use sharp, non-retractable claws to grip the ground while their long legs push them forward. Moving their long tail side-to-side helps them change directions while running.


Female cheetahs live and hunt alone, while male cheetahs often live in a small group called a coalition. Males can catch larger prey and are usually more successful than females because they hunt as a team. When food in an area becomes scarce, cheetahs (like most predators) must look for prey somewhere else. However, traveling to new parts of the savanna is becoming more and more challenging because of habitat fragmentation.


National parks have been created across Africa to protect cheetahs and other wildlife, but moving between the parks requires crossing fences, cities, farms, and roads. Cheetahs now have trouble finding new feeding areas and reaching mates. Cheetahs must travel to find new mates to produce healthy offspring and increase population size. Scientists are working to save cheetahs by creating connected areas between habitats that will allow cheetahs and other wildlife to move around safely.

BRAIN BLAST

Another threat cheetahs face is human-wildlife conflict. As the savanna changes into cities and farms, cheetahs live closer and closer to people and their livestock, like goats and sheep. Cheetahs are often killed to protect livestock. Come up with a strategy to keep cheetahs away from livestock that will not restrict the cheetahs' movement around the ecosystem.

Restoring African Painted Dog Populations

African painted dogs live and breed in large packs on the African savanna. Usually, after pups are born and grown, some leave the pack to find a new pack to join and breed with.


It is important that animals breed with others they are not related to, or it could cause the offspring to have health problems. Animals typically spread out around their ecosystem to find unrelated mates to breed with. Habitat fragmentation prevents African painted dogs and other animals from spreading out, so scientists are taking matters into their own hands.


Recently, scientists have relocated small groups of African painted dogs from one part of Africa to another to help them spread out! In one event, a group of orphaned pups joined new packs in different park. In another, several adult painted dogs were moved to start a pack in a new area. These relocations are a great way to make sure the future of the African savanna includes healthy African painted dogs.
