The main source of data for the update cameįrom a series of aerial surveys of 18 African nations during the Great ElephantĬensus, a Paul G. Due to minimal attention, such detailed range maps for New research will be an important baseline from which real range changes can be Research group Movement Ecology, at the Senckenberg Biodiversity Climate

Past two years,” said Thomas Mueller, Ph.D., senior author and head of the These changes are likely more a reflection of the increased accuracy of theĭata available than a reflection of decrease or increase of ranges over the Range of reticulated giraffes was larger than previously thought.” Ranges of both northern giraffes and Masai giraffes have decreased, but the Showing greater sensitivity to habitat shifts,” said O’Connor. Under distress can show complicated patterns of change, with some species In some countries, ranges for certain giraffe species had shrunk while others had increased. Although ranges were larger in some African countries than previously reported, in seven nations -Cameroon, the Central African Republic, Chad, Malawi, Niger, Uganda and Zambia-giraffe ranges had declined significantly. giraffa (Southern giraffe).Īccording to the IUCN Red List of Threatened Species, giraffe populations have declined by over 40 percent in the last three decades, with significant changes seen in their available habitat due to increased human activity. Updated geographic range for all four giraffe species: This new research provides the most accurate range maps for giraffes that have everīeen produced. Of Africa.” The first step in saving these species is knowing where they are, and Partner with African governments to ensure giraffes survive and remain an icon But that isĬhanging we and our partners have been working hard to secure funding and Unfortunately, the fate of these giants has largely gone unnoticed. “AcrossĪfrica, giraffes are in decline, and some are in serious risk of extinction. O’Connor, Population Sustainability researcher for San Diego Zoo Global. While another two types are listed as Endangered,” said lead author David “Today, two types of giraffe are listed as Critically Endangered, Species’ assessment map of giraffe ranges. International Union for Conservation of Nature (IUCN) Red List of Threatened The results of the work show aĥ.6 percent decline in the range area of all giraffes, compared to the 2016 Studied using both ground and aerial surveys. Giraffe, southern giraffe, reticulated giraffe, and Masai giraffe- were Series of updated maps detailing current ranges of giraffes throughout Africa. Research Centre have published a groundbreaking new scientific paper with a Giraffe Conservation Foundation and the Senckenberg Biodiversity and Climate International group of conservation scientists led by San Diego Zoo Global, the
