Gorillas and Deer - Habituation as a tool for conservation

 This post is an amalgamation of two previous posts one on habituation and one on Virunga. Virunga was a powerful 2014 British documentary directed by Orlando Von Einsiedel that focused on the work of park rangers in Congos Virunga National Park and in particular the struggle to protect mountain gorillas. The habituation post related to my gradual acceptance of my present by the resident Doe and her two young females that have developed this year. Today I had my most intimate and relaxed encounter with them. They allowed me to sit some 40 metres away and grazed naturally mostly at ease, exhibiting natural behaviour. These two disparate things coalesce when considering another recent documentary, Silverback.

Silverback is a documentary by wildlife cameraman, Vianet Djenguet. The explores the themes surrounding the work of conservationists in the Kahuzi-Biega National Park in the Congo and their aim to habituate eastern lowland gorillas for tourism.

Through Vianet we are introduced to the dedicated rangers on the ground, the scientist managers, and the gorillas themselves. Conservation in Africa is difficult and complex, no one can deny the pressures on the local Congolese people living in a war-torn country and often this brings them into conflict with the local wildlife, poaching, and the bush meat trade are particularly disturbing but as a country develops most damaging is the loss of primary forest to make way for cattle, crops and development. The plan, which is already in action, is to habituate gorilla families so that tourists can safely be taken to view them. This tourist trade would provide valuable revenue to fund conservation measures like protecting land and show the local people the value of conserving wildlife around them.

Vianet joins the rangers for 3 months, during which they spent each day with a family of gorillas led by a Silverback called Mpungwe. Vianet started off wholly engaged in the project but slowly came to doubt the merits of the initiative as the knowing doubt that was in the back of my mind the whole time came to the fore.

There is considerable merit in the concept of involving local people in the management of their natural resources and given that all the people shown were from Congo exemplified this and removed any suggestion of the ‘white west’ dictating what the former colonies now do in their own country, but that is a whole other kettle of fish and a debate best saved for another time and place.

Mpungwe was a somewhat aggressive gorilla, but perhaps no more so than would be expected from someone who had lost his parents violently and is disturbed each day by a camera crew, and, here is the crux of habituation, the individual needs to be receptive and have the correct temperament. Mpungwe was not the first gorilla to be habituated, there had been successes elsewhere in the Congo but he seemed wholly unpredictable and unsettled by the whole affair for the techniques to be effective. Whilst there did seem to be some progress, a begrudging tolerance perhaps, Mpungwe seemed unable or perhaps more accurately unwilling to totally accept the presence of humans around his family.

To persevere with the attempts at habituation, which is where the programme left us, risks causing Mpungwe more stress. Doctors live by the Hippocratic Oath, to first do no harm something that Ecologists and scientists should also live by even if it isn't codified in the same way.

Towards the end of the film Vianet seemed to be having second doubts, he acknowledged Mpungwe's discomfort and wondered if this was too high a price to pay. It's a valid point just as the technique of habituation is for tourism, but there is certainly an ethical line that needs to be explored. All of us need to rationalise how far we should go to safeguard a species. How far is too far and who decides?

I am uncomfortable with the concept of habituation, for me, it leads to a change in natural behaviour and desensitising a creature to man can be dangerous, this is less of a problem in this country with my deer per se but where active hunting is a problem then it could be deadly.  For my deer I want them to remain wild, and whilst some habituation makes it possible for me to observe them closer and get some great pictures anymore would be unjust and unfair, for Mpungwe it is much more complex, the rangers of Kahuzi-Beiga are trying to save a species and in the modern world that requires compromise.

Pelagic Publishing - A Book Review

It's been a while since I have done a book review and so when I got a new wildlife book for Christmas and then decided to get a few more I thought I would like to look at Pelagic Publishing’s Data in the Wild Series. 



 Pelagic Publishing is fast becoming one of my favourite conservation publishers. It was founded in 2010 and has a steady output of conservation-focused texts that lean towards the practical application of ecology. 

 The internet provides us with a wealth of up-to-date information but nothing beats the ability to hold a book in your hands and browse the information. Statistics for Ecologists Using R and Excel and Community Ecology – Analytical Methods using R and Excel are two books that benefit from having a physical quality. When learning new software or manipulating your data in a spreadsheet it is so much easier to refer to a textbook than to constantly flick between a bewildering number of windows containing webpages, adverts, and YouTube clips to achieve your aims. Both these books explore simple and complex ecological themes providing step-by-step ways in which R or Excel can be used in analysis. Just from using these books I have managed to get a grip on R and can generate several statistical tests and output graphical representations. The books are backed up by trail data sets and web links marrying the physical with the virtual. 


 The other two books I have in the series are Measuring Abundance and Camera Trapping for Wildlife Research. The latter, I got a while ago and have helped shape and develop my ongoing camera-trapping project. Both books collate up-to-date information on their topics with relevant case studies and useful coding for use in R. In terms of level, the books are certainly not for the novice reader, you need an understanding of ecological theory and knowledge of mathematical notation and application. The books assume that you have this background and do not go far to explain in depth what the measures they are describing merely how to calculate them. 

Data in the Wild is an indispensable series for practical ecologists who are engaging in research. It helps focus on how projects are set up and aids in the analysis of data collected and presented. Pelagic Conservation Handbooks are a welcome addition to wildlife management and are a concise guide to habitat assessment and practical methods of management. I currently own the Woodland Survey Book which has helped me analyse and survey the woodland on my patch and as an extensive user of QGIS I am waiting with bated breath for their upcoming title, QGIS for Ecologists due this June.
