31 July is World Ranger Day. World Ranger Day commemorates rangers killed or injured in the line of duty and celebrates the critical work rangers do to protect the world’s natural and cultural treasures. Each painted rock is a memory in honor of a ranger killed in the line of duty. Wild Nature Institute honors a ranger's memory with our Rangers Rock giraffe rock.
Wild Nature Institute stands with the International Ranger Federation and PAMS Foundation to thank and celebrate all of the world's rangers for sticking their necks our to protect giraffes and other precious wildlife -- sometimes losing their lives in defense of species other than themselves. They are true heroes in a world where we desperately need such people. We thank the world's rangers from the bottom of our hearts.

In 2018, Wild Nature Institute commissioned a local gospel choir to record the song Tuwatunze Twiga, which means “let’s protect giraffes.” The song describes how giraffes are beautiful and God tells people to conserve giraffes, but that giraffes are threatened by poaching. The song was played on a major radio station servicing the Tarangire-Manyara region, every day for the entire months of December (2018) and January (2019). To document community perceptions of giraffes and whether they were influenced by the Tuwatunza Twiga song, James Madeli of the Wild Nature Institute in Tanzania administered short surveys of randomly selected community members before and after broadcast of the song. We are excited to announce the new report prepared by Madeli and our colleagues Alex Ocañas and Dr. James Danoff-Burg of The Living Desert Zoo and Gardens. Ocañas and Danoff-Burg are experts in the human dimensions of conservation, and helped us design the survey questionnaire and analyzed our survey data. This report documents the impacts of this conservation media project on perceptions of giraffes by community members. The report revealed some interesting information that will improve Wild Nature Institute’s giraffe conservation messaging in the future. In summary, the data showed:
Our results indicate that the song appealed to people’s religious beliefs, and suggest that in the future we could leverage these beliefs to improve our conservation messages. We will be including this project in an upcoming book to be edited by Dr. Derek Lee and Dr. Monica Bond of Wild Nature Institute called Tarangire: Human-Wildlife Coexistence in a Fragmented Ecosystem. Please see the full report for details. We thank all of our donors for supporting our giraffe conservation projects in Tanzania – we could not do this work without you. Thank you to James Madeli whose hard work in the field generated these data. Thank you also to Alex Ocañas and Dr. James Danoff-Burg for doing an excellent job on this important report, and The Living Desert for being our long-term conservation partners. #StandTallForGiraffes
What a day! The longest day of the year in the northern hemisphere, a day to thank our dads for all that they do in our lives, and a special day to celebrate giraffes! We wish you all a wonderful day. With our partners we are running the world's largest #giraffe #research and #education program helping people and giraffes thrive together.

June 9, 2020 A new study by an international team of scientists from the Wild Nature Institute, University of Zürich, Max Planck Institute of Animal Behavior and the University of Konstanz, and Pennsylvania State University showed that communities of giraffes living in proximity to human settlements have a tell-tale signature of disturbed social networks. While many of the most charismatic animal species are social, the effects of human-caused disturbances on the social relationships of wild animals has rarely been studied. The authors applied state-of-the-art social network analyses on 6 years of observations from more than 500 wild adult female giraffes to reveal that human proximity is correlated with weaker and more exclusive relationships with fewer individuals among giraffes. The study, published in the Journal of Animal Ecology, provides the first robust evidence that humans modify social structure in this iconic megaherbivore. Effects of humans on social structure of wild animal populations has not been widely studied For social animals, including species such as elephants, lions, and giraffes, social behaviour is critical for survival and reproduction. Recent studies on laboratory populations of birds have suggested that disturbances to social groups can precipitate changes to the social structure of those groups, which then has consequences on how the groups can perform at tasks that are important for survival—such as feeding together. As humans continue to encroach on the land used by wildlife, there have been conservation concerns arising from the resulting human-wildlife conflict, such as killing of elephants and poisoning of lions. However, the increasing contact between animals and humans could also have indirect, but profound, impacts on populations that are not directly persecuted by humans. Scientists know little about the effects on wild animal social relationships from subtle or indirect disruptions caused by human presence and encroachment into natural habitats. Field research in Tanzania yields new insights into giraffe social relationships
“Detecting signals of natural versus human-caused influences on social relationships among wild animals is challenging,” noted Monica Bond, Wild Nature Institute scientist, research associate at the University of Zürich, and primary author of the study. “It requires large-scale studies of individually identified animals across numerous social groups living under different environmental conditions.” Individual giraffes can by identified by their unique and unchanging spot patterns. Over a period of 6 years, Bond and her research collaborators collected photographic identification data spanning 540 adult female Masai giraffes inhabiting a large, unfenced landscape in the Tarangire Ecosystem of Tanzania—an environment that features varying levels of anthropogenic (human-caused) disturbances. Bond’s team documented that the female giraffes in Tarangire live in a complex multilevel society, with individuals preferring to associate with some females while avoiding others. The result of these preferences are discrete social communities comprising 60-90 females with little mixing among the communities, even when these share the same general area. “This study reveals that social structuring is clearly an important feature of female giraffe populations,” noted Dr. Barbara König, professor at the University of Zürich and co-author of the study. In Tanzania, giraffes are tolerated by humans because they do not create conflicts with farmers or livestock. “Despite the public tolerance and hunting restrictions, Masai giraffe populations have declined 50% in recent years,” stated co-author Dr. Derek Lee, Wild Nature Institute scientist and associate research professor at Pennsylvania State University. Several reasons have been suggested, including illegal poaching, habitat loss and fragmentation, lion predation on calves when migratory herds decline, and changes in food supply. Disruption to social systems also may be a contributing factor in population declines, but until now, anthropogenic effects on social structure of giraffes were unclear. Using one of the largest-scale metapopulation networks ever studied in a wild mammal, the research team revealed that giraffes living closer to traditional compounds of indigenous Masai people exhibit weaker relationship strengths and more exclusive social associations. “This result signifies a disrupted social environment based upon previous experimental research,” noted Dr. Damien Farine of the Max Planck Institute of Animal Behavior and the Centre for the Advanced Study of Collective Behaviour at the University of Konstanz, and senior author of the study. “The patterns we characterise in wild giraffe’s response to proximity to humans reflect the predictions from experimentally disrupted social systems.” Near traditional human settlements called bomas, fuelwood cutting can reduce giraffe food resources, and groups of giraffes are more likely to encounter livestock and humans on foot, potentially causing groups of giraffes to split. However, human settlements might also provide protection from lions and hyenas which are fewer near bomas, and in other research the team found that groups of female giraffes with calves tended to occur closer to bomas, and giraffe communities closer to bomas produced more calves per female. “It seems that female giraffes face a trade-off between maintaining important social bonds and reducing risk to their calves near these traditional settlements,” stated Bond. She suggests that traditional pastoralist livelihoods do not necessarily pose a significant risk to giraffe population persistence as long as care is taken not to cause excessive disturbance. The study’s results imply that human presence could potentially be playing an important role in determining the conservation future of this megaherbivore. Further, the study’s leading-edge methodology highlights the importance of using the social network approach to reveal otherwise hidden potential causes of population declines. “The effects of ever-increasing anthropogenic pressure on wildlife populations are determined by complex interactions of individuals with their social, biological, and physical environment,” said Arpat Ozgul, study co-author and professor at the University of Zürich. “Our study highlights the importance of characterising these complex interactions accurately for gaining much needed insight into population responses to environmental change [or anthropogenic pressure].” Wild Nature Institute's Monica Bond successfully defended her PhD on 8 May from the Department of Evolutionary Biology and Environmental Studies at the University of Zürich. Her research focused on the dynamics of a socially and spatially structured giraffe population in a coupled natural-human landscape, the Tarangire Ecosystem.
From all of us at the Wild Nature Institute, happy Earth Day! This is the 50th anniversary of the first Earth Day in April 1970. Humanity is now much more aware of the fragility of our precious planet, and the threats. But we have a long way to go to protect the web of life. We hope the lessons learned from the biodiversity and climate crises, and from the Covid-19 pandemic unleashed by our exploitation of nature, will lead to a brighter, healthier, happier future for all life on Earth.
The primary schools in Tanzania are closed due to the Covid-19 pandemic. But learning about giraffes doesn't have to be put on hold. Glory is a class six student at Mtowambu Primary School. Yesterday she went to the Wild Nature Institute office in Mtowambu and borrowed a Juma the Giraffe book to read to her younger siblings while they looked after the family's goats. As James Madeli, Wild Nature Institute's Education Coordinator said, "They have shown that they love stories about giraffes, and that makes me happy." Thank you Glory for teaching your siblings about giraffes, and thank you James for sharing this inspirational story. We need more happy stories in these challenging times. #StandTallforGiraffe
