Density-dependent factors: Food availability decreases as population size increases; space limitations cause birth rates to decline as population size increases; predation becomes more intense as population size increases Which decade had, or is projected to have, the highest annual population increase? Home ranges are as small as 85 square km (33 square miles) in wetter areas but up to 1,500 square km (580 square miles) in dry regions. Less food available during the dry season (Parker and Bernard 2005); also during drought attributed to El Nio weather cycles. Giraffe numbers are 20 percent higher than in 2015, an increase linked to conservation efforts and more accurate survey data. But take some time to think about them, about their size. Conservation groups, including San Diego Zoo Global, are working to protect giraffes. Giraffes in the wild tend to live between 20 to 25 years. Because the species is so endangered, there are only four different types of giraffes still left in existence. clumped pattern: unequal distribution of resources, giraffes eat leaves and branches of savanna During the 20th century, the human population increased from less than 2 billion to more than 6 billion.

According to a recent analysis of survey data from across the African continent, the total giraffe population is now around 117,000, approximately 20 percent higher than it was thought to be in 2015, when the last major survey was published. A study in 2016, however, determined that habitat loss resulting from expanding agricultural activities, increased mortality brought on by illegal hunting, and the effects of ongoing civil unrest in a handful of African countries had caused giraffe populations to plummet by 3640 percent between 1985 and 2015, and, as of 2016, the IUCN has reclassified the conservation status of the species as vulnerable.
