Giraffes Could Go Extinct – The 5 Biggest Threats They Face

Giraffes are the world’s tallest mammals and an African icon, but they are also vulnerable to extinction.

Giraffe populations have declined by 40% in the last 30 years, and there are now fewer than 70,000 mature individuals left in the wild. What are the causes of this alarming decline, and what can be done to protect these gentle giants?

The five biggest threats to giraffes are habitat loss, insufficient law enforcement, ecological changes, climate change, and lack of awareness. Below, I will tell you about these threats and what is being done to save them.

Habitat degradation, fragmentation and loss

Giraffes need large areas of savanna with abundant native bushes and trees to feed on. The biggest threat to giraffes is the degradation, fragmentation and loss of their habitats through human activities such as farming and human settlement expansion.

Habitat loss outside protected areas is the main reason for the recent decline in giraffe numbers. National parks provide most of the remaining habitat. Some good habitat remains unprotected but is cared for by pastoralists.

Traditional pastoralists like the Maasai in northern Tanzania maintain large spaces of natural savanna where wildlife and people thrive together.

However, most people now living in areas that were giraffe habitat are sedentary. As populations of farmers and townspeople expand, giraffes are forced into smaller and more isolated patches of land. This reduces their access to food and water, and increases their vulnerability.

Conservationists are working to safeguard existing unprotected giraffe habitat and maintain or restore the connections among protected areas. Community-based natural resource management is central to this activity. It gives local communities the legal power to protect their land and resources.

Insufficient law enforcement

Another major threat to giraffes is illegal hunting (poaching) for bushmeat markets. This is usually controlled by international criminal syndicates.

Strong wildlife law enforcement is the best tool to combat this threat. Conservationists are working to strengthen local and international law enforcement around wildlife crimes, and to reduce the demand for giraffe products. At the grassroots level, this requires supporting anti-poaching patrols by rangers and village game scouts. It’s also essential that communities should have legal alternative ways to make a living.

Ecological changes

A third major threat to giraffes is human-caused ecological change that affects their food availability and mobility. These changes include deforestation of savannas for fuelwood and charcoal production, mining activity, and road and pipeline building. Water diversion and groundwater pumping also affect their habitat and access to water.

Mining, roads and pipelines can disrupt the natural movement patterns of wildlife, leading to smaller, more isolated populations that are more susceptible to local extinction.

Conservationists are promoting sustainable forestry, new cooking techniques such as gas stoves, water conservation and planning for groundwater resources, and building wildlife crossings into roads and pipelines.

Climate change

Climate change from human-caused carbon dioxide pollution is forecast to increase temperatures and rainfall in many African savanna areas. Giraffes are unaffected by the higher temperatures observed so far, but increased seasonal rainfall is associated with lower giraffe survival due to disease and lower food quality.

Over the longer term, more rainfall will create conditions favourable to increased woody plant cover in savannas. This could help giraffes by increasing their food supply, but only if enough natural savanna is preserved from human exploitation.

Lack of knowledge and awareness

The fifth major threat to giraffes is the lack of knowledge and awareness about their conservation needs. Giraffes are often overlooked and underrepresented in wildlife research, funding and policy. Many people are unaware that giraffes are endangered and face multiple threats across Africa.

Conservationists are working to increase knowledge and awareness about giraffes locally and worldwide. Scientists are studying giraffe demography, diet, behaviour and genetics, and there is a large environmental education programme in Tanzania, the US and Europe.
