A holistic approach to elephant conservation

8/11/2021

0 Comments

 
Elephant conservation is a complex issue that requires support and funding in multiple areas to be successful. Founded in 2012, the International Elephant Project (IEP) works to protect and conserve elephant populations and their rainforest habitat in South-east Asia through a holistic approach to conservation.
 
This starts at the grassroots level, working with and involving local indigenous communities.
 
IEP supports a wide range of critical on-the-ground projects in Borneo, Sumatra, and Laos that address the problems facing remaining fragmented elephant populations - including fighting deforestation, human-elephant conflicts and poaching.
 
A major strategy is to radio collar and track elephant herds by satellite. Human Elephant Conflict Mitigation teams then follow the herds and work with local communities to see that both elephants and humans remain safe and live in harmony. By monitoring and protecting multiple elephant herds, we can ensure sufficient numbers and genetic diversity to survive.
 
A new book authored by IEP’s Field Manager, Dr Alexander Mossbrucker, highlights the work of IEP in protecting the Critically Endangered Sumatran elephant, the most endangered of all the Asian elephant species. For the past ten years, Alex has been working alongside a team of dedicated local conservationists who engage in various activities to help mitigate the threats to elephant populations, including ranger patrols, wildlife monitoring, human-wildlife conflict mitigation and community education.

REVIEW: Understanding elephants - Guidelines for safe and enjoyable elephant viewing

22/5/2017

5 Comments

 
Understanding Elephants - Guidelines for safe and enjoyable elephant viewing examines elephant behaviour and provides guidelines on how to conduct yourself near elephants. On average, up to three people are killed annually in South Africa by elephants, and another three are seriously injured. The majority of these incidents could have been avoided had the people involved better understood elephant behaviour and been able to read the tell-tale signs. Often an attack is not just potentially tragic for the people involved, it leads also to the demise of the animal too.
This book hopes to provide a better understanding of elephant behaviour and of how to avoid a negative or unfortunate encounter with these majestic animals. Suggestions are offered on how to behave when driving near elephants, as well as how to react in difficult or dangerous situations.


In the first chapter the reader gets some global elephant facts, such as age-related differences, sexual differences, how to detect if elephants are nearby, how to identify them individual, etc.
The second chapter gives you an insight into the social behavior of these beautiful gentle giants.
When viewing elephants on a safari it’s important to know if a certain male elephant (bull) is in musth or not. During this period, testosterone hormone levels in the blood of a male increase (up to 50-fold compared to non-musth levels) and, as a result, the bull becomes more aggressive. So you are wise to keep your distance when bumping into a bull in musth. But no fear, chapter three tell you all you need to know.
Elephants are megaherbivores and are so-called ’keystone’ species, which means they are able to change the habitat they live in and function as drivers in various ecological processes that can influence other species. Chapter four tells you more about elephants their ecology and environment.
Why do elephants entwine their trunks or place their trunk tips into the mouth of other elephants? What means the rumbling or trumpeting? Chapter five tells you all about the communication of elephants.
Elephants have the largest brain of all terrestrial animals, and in relation to their body size, comparable to those of great apes. So they are very intelligent. Did you know they also have empathy? Read all about it in chapter six.
Where chapters 1-6 are rather theoretically, chapters 7-9 focuses on how you need to behave in the presence of elephants: reading their signals, how close you can go, do’s and don’ts,...

Despite the fact that Understanding elephants isn't a thick book, only 68 pages, all you need to know is in it. It’s your perfect companion when observing elephants in a respectful and ethical way.

Asian elephants acquire inaccessible food by blowing

10/11/2015

1 Comment

 
Many animals acquire otherwise inaccessible food with the aid of sticks and occasionally water. As an exception, some reports suggest that elephants manipulate breathing through their trunks to acquire inaccessible food. Here, we report on two female Asian elephants (Elephas maximus) in Kamine Zoo, Japan, who regularly blew to drive food within their reach. We experimentally investigated this behaviour by placing foods in inaccessible places. The elephants blew the food until it came within accessible range. Once the food was within range, the elephants were increasingly less likely to blow as the distance to the food became shorter. One subject manipulated her blowing duration based on food distance: longer when the food was distant. These results suggest that the elephants used their breath to achieve goals: that is, they used it not only to retrieve the food but also to fine-tune the food position for easy grasping. We also observed individual differences in the elephants’ aptitude for this technique, which altered the efficiency of food acquisition. Thus, we added a new example of spontaneous behaviour for achieving a goal in animals. The use of breath to drive food is probably unique to elephants, with their dexterous trunks and familiarity with manipulating the act of blowing, which is commonly employed for self-comfort and acoustic communication.

Elephant poaching in Niassa Reserve, Mozambique: population impact revealed by combined survey trends for live elephants and carcasses

28/10/2014

1 Comment

 
Trends in the populations of large herbivores in Niassa Reserve, Mozambique, have been monitored through biennial aerial surveys since 1998. The elephant Loxodonta africana population has been subjected to intensive illegal hunting since 2006. We used a simple population model to mimic the observed trends in the numbers of live and dead elephants to demonstrate the impact of poaching. The number of fresh or recent carcasses recorded was used in the model as an index of the annual mortality rate. A maximum likelihood analysis to compare population models revealed that the best fit to the survey estimates of both live elephants and old or very old carcasses was a model that started with 6,635 elephants in 1987. This number increased through births by 4.6% annually and decreased through deaths from natural and anthropogenic causes. In the best-fit model, the mean mortality rate in any year was 3.2 times the observed 1 + 2 carcass ratio (ratio for carcasses in age categories 1 and 2, and carcasses remained visible for a mean of 6 years. The model suggested that c. 900  elephants were poached during 2007-2010 and another c. 1,000 during 2011. Population estimates for live elephants and carcasses are now routine outcomes of aerial surveys conducted as part of the CITES program me for Monitoring the Illegal Killing of Elephants, and our method can be applied to any population with a time series of estimates for live and dead elephants.

Elephant (Loxodonta africana) impact on trees used by nesting vultures and raptors in South Africa

11/6/2014

0 Comments

 
Negative influences on the establishment and persistence of large trees used by tree-nesting birds as nesting sites represent a potential threat to vultures and raptors. We monitored large trees and their surrounding vegetation and analysed whether trees with nesting sites are at risk due to elephant impact. Trees with nests did not differ in elephant impact from control trees without nests, and the survival rates of trees with nests and the actual nests within the trees showed that nests decreased at a faster rate than the trees themselves. Elephant damage did not affect the persistence of nests over the 5-year monitoring period. However, the presence of insects and fungus on large trees was negatively related to tree survival, thereby indicating that elephant impact could indirectly facilitate insect and fungus attack and shorten the lifespan of a tree.

Asian elephants (Elephas maximus) reassure others in distress

18/2/2014

Contact directed by uninvolved bystanders toward others in distress, often termed consolation, is uncommon in the animal kingdom, thus far only demonstrated in the great apes, canines, and corvids. Whereas the typical agonistic context of such contact is relatively rare within natural elephant families, other causes of distress may trigger similar, other-regarding responses. In a study carried out at an elephant camp in Thailand, we found that elephants affiliated significantly more with other individuals through directed, physical contact and vocal communication following a distress event than in control periods. In addition, bystanders affiliated with each other, and matched the behavior and emotional state of the first distressed individual, suggesting emotional contagion. The initial distress responses were overwhelmingly directed toward ambiguous stimuli, thus making it difficult to determine if bystanders reacted to the distressed individual or showed a delayed response to the same stimulus. Nonetheless, the directionality of the contacts and their nature strongly suggest attention toward the emotional states of conspecifics. The elephants’ behavior is therefore best classified with similar consolation responses by apes, possibly based on convergent evolution of empathic capacities.

Forest Elephants Establishing Communities Near Humans and Development in Gabon

8/1/2014

0 Comments

 
Conservation of wide-ranging species, such as the African forest elephant (Loxodonta cyclotis), depends on fully protected areas and multiple-use areas (MUA) that provide habitat connectivity. In the Gamba Complex of Protected Areas in Gabon, which includes 2 national parks separated by a MUA containing energy and forestry concessions, we studied forest elephants to evaluate the importance of the MUA to wide-ranging species. We extracted DNA from elephant dung samples and used genetic information to identify over 500 individuals in the MUA and the parks. We then examined patterns of nuclear microsatellites and mitochondrial control-region sequences to infer population structure, movement patterns, and habitat use by age and sex. Population structure was weak but significant, and differentiation was more pronounced during the wet season. Within the MUA, males were more strongly associated with open habitats, such as wetlands and savannas, than females during the dry season. Many of the movements detected within and between seasons involved the wetlands and bordering lagoons. Our results suggest that the MUA provides year-round habitat for some elephants and additional habitat for others whose primary range is in the parks. With the continuing loss of roadless wilderness areas in Central Africa, well-managed MUAs will likely be important to the conservation of wide-ranging species.
