During the summer of 2017, Naturevolution organized a new great scientific expedition multidisciplinary in the Makay massif in Madagascar, the fourth since 2010. Access to roadbook of the expedition.
A new expedition to the Makay
Summary
This new scientific mission took place from July 22 to September 2, 2017. It took place exactly ten years after the first crossing of the Makay : an event that triggered the founding of Naturevolution, the first scientific expeditions in 2010 and 2011 into the massif, and the creation of New Protected Area of the Makay.
In this mountain rangelocated in the center-west of the island, erosion carved over several hundred million years a maze of deep canyons. There, life took shelter in near autarky, occupying all vacant ecological niches. In these isolated ecosystems, free of human observation, biodiversity has developed and diversified, leading to the emergence of new species.
A collaborative undertaking
Under the lead of Naturevolution, several players have pooled their skills to make this mission a success on several levels. La Société des Jeunes Aventuriers First who was the first frame of the scientific team with 5 students of the National Museum of Natural History in Paris. The People Although Productions and ArteThe youtubeur Leo Grasset (Dirty Biology) as well as NatExplorers, A duo of talented scientists and biologists mediators, all filmed in their way and valued the work of scientists and explicit conservation issues.
Aurélie Calmet, l’illustratrice habituée des expéditions de Naturevolution, a amené pour la première fois ses carnets et ses pinceaux dans le Makay. Enfin, l’expédition a réuni plusieurs dizaines d’écovolontaires venus prêter main forte aux scientifiques, découvrir le Makay et contribuer au financement de l’expédition.
Participatory science in the field
For the first time, Naturevolution took on a scientific expedition many ecovolunteers attracted by the prospect of contributing to research projects, assisting to the conservation of the Makay massif and living an amazing adventure in a spectacular and secluded nature.
Cet agglomérat de bonnes volontés a surtout permis, dans l’esprit des sciences participatives, de réaliser en simultané counting and mapping projects of several species (Among other lemurs) in major forest areas of Makay: Menapanda, the largest forest in the Makay; Makaikely south, a forest encased in beautiful canyons that had not yet given rise to any study; Mahasoala north, 2nd forest massif, also virgin until scientific studies.

What the scientists will focus on
Cette nouvelle expédition scientifique dans le Makay a été la première à avoir lieu en saison sèche. Si cela n’a pas facilité pas les observations, plus aisées en saison humide, cela a permis en revanche d’étudier la faune et la flore dans la transition de cette période difficile. Cette expédition a été également la première à étudier les zones forestières de Makaikely et de Mahasoa, deux des plus grandes forêts du Makay, situées respectivement au sud et au nord de la grande forêt de Menapanda.
Lemurs
Gaëtan Deltour (Naturevolution) et Anselmo Andriananandrasana (GERP)
Animal emblématique de Madagascar, c’est aussi un des mammifères les plus menacés de la planète: 94% des espèces de lémuriens apparaîssent dans la liste rouge de l’IUCN, faisant de leur conservation une priorité. Le Makay, avec 9 espèces confirmées de lémuriens, est un des endroits de Madagascar où l’on en trouve la plus grande diversité d’espèces. Un large projet a été déployé cet été pour l’étude et le suivi des lémuriens du Makay.
Mapping of lemur populations
Establishment of exhaustive monitoring of lemur populations with a systematic mapping of the groups encountered. To help eco-volunteers identify these animals, a new tool on a mobile device created at the MNHN was tested on site: CLEMURS.
Study of adaptation to the environment
Anatomical and morphological studies from captured specimens have shed light on the adaptation of these animals in this unique environment.
Diet study
Biological and genetic studies of the faeces aimed to determine the precise diet of Makay lemurs in order to adapt reforestation programs accordingly.
Carnivores, Rodents and Bats
Margot CHAUD, Rohan suit, Paul Nicolas (Naturevolution); Martin Raheriarisena et Steven Goodman (Wolfgang)
Read the detail of the research project on carnivores and bats (French).
Répartition et capture d’images de fossas
The fossa, elusive féliformes are endemic carnivores of Madagascar. Still to this day, little is known about their presence in the Makay. The goal was to better understand their distribution in the massive and capture the first images using camera traps.
Mapping of bat colonies
Acoustic methods were used to identify bat species and look for new colonies to obtain a first population census in the massif.
Rodents
Specimens small lemurs (lemurs) were observed. Rodents were captured at the same time, and morphological and anatomical studies were conducted.
Ferns, Briophytes, Angiosperms and Canariums
Catherine Reeb (Naturevolution) and Rado Ramahandrison (University of Antananarivo)
Inventory of ferns and angiosperms
This survey was conducted as a classic technique inventory quadrat by unpublished vertical transects on the walls of the massif to raise flora.
Counting of canarium trees
The canarium is a species of tree from which the resin is used in perfumery. This impact assessment was to determine whether the density of canariums is sufficient for operating small-scale resin to generate additional income for the villagers Makay and value in their eyes healthy forest.
Birds
Vincent Roméra (Agence VISU), Anne-Sophie Lafuite (CNRS) and Eric Marcel Temba (Antananarivo University/Asity)
Inventaire de l’avifaune
Equipped with binoculars, telescopes and cameras, birding team continued the inventory of the avifauna of the Makay with a focus on birds of prey. A basic sound data and images was incorporated to compare with other forests of Madagascar. The ornithology component detail
Insects and crustaceans
Benoît Gilles (Naturevolution) and Jean-François Cart (IUCN)
Collection and inventory
En utilisant des méthodes très variés de collectes, ces 2 passionnés ont réalisé un inventaire des espèces en saison sèche et rechercher de potentielles nouvelles espèces.
Archeology
Antoine Heurtel (Naturevolution)
Cartography, new spots search and conservation strategy
La découverte en 2010-2011 de 465 peintures rupestres (the first of Madagascar) highlighted a unique archaeological wealth in Makay. This invaluable heritage has been studied through a mapping program, the search for new sites and studies with a view to the rapid implementation of a conservation strategy for these rapidly degrading sites. Samples of fallen fragments were taken for dating.
Fishes
Megann Texereau (Naturevolution) and Jean Robertin Rasoloariniaina (CNRE)
Inventory of species and studies of milieu
The inventory of fish species in Makay was continued. In 2010-2011, the discovery of a new species of Pachypanchax sp. scored shipping. A thorough study of its environment and its range was the program and the animal was found and captured ..
A lower environmental impact
ATVs, certainly comfortable but inefficient, have been used until they were absolutely necessary. Local collective vehicles were privileged to rally the doors of the massif, and several junctions were made on foot. Inside the massive porting material was done on their backs, which has brought extra additional income to the villagers.
An expedition related through various channels
To share this adventure more and continue our advocacy for the protection of lost worlds, we have been keen to communicate over multiple channels and most varied possible.
A daily diary in text and video
A reporter embedded to tell the shipping daily text and picture format. Evrard Wendenbaum presented meanwhile on some videos, explored places, the equipment used, research and actions on the ground and the members of the team.
These publications were posted on the roadbook, via Facebook and Instagram.
A 52 minute documentary
Evrard Wendenbaum, in collaboration with Gil Kebaïli and The People Of Production, produced a "discovery" documentary on the entire expedition for a broadcast at the start of 2018 on Arte and in many festivals and conferences.
A short film crazy popular science
Leo Grasset, the Youtuber on steroids of the channel Dirty Biology was there and the result is excellent!
A scientific web series
The talented scientific mediators of NatExplorers, present throughout the mission, produced a video web-series on the scientists' research, the challenges and difficulties of the conservation of Makay. These videos were posted on Youtube and social networks. They will also feed the multimedia library intended for the world of education that we will soon put online on our new site to come.
Radio operations
Interventions waves were carried out in particular in the program " Time for a bivouac "France Inter who spent several interviews live by satellite phone.
Illustrations and exhibitions
The work of scientists and animals Makay was also masterfully illustrated by Aurélie Calmet and Alix Thiebault, and their illustrations can be seen on the expedition blog. The expedition also gave rise to a traveling exhibition on the Makay, et sera prochainement le sujet d’une exposition temporaire de plus grande ampleur.
A book
After sharing 3 scientific expeditions, Aurélie Calmet (illustrations) and Evrard Wendenbaum (Photos) are preparing a joint book. A guide to the fauna and flora of Makay is also in preparation.
