Abstract

Madagascar is a biodiversity hotspot, yet its wildlife is under immense threat from habitat loss and other anthropogenic pressures. To tackle this, Madagascar has implemented new environmental legislation, including rapid expansion of the protected area network. Many new protected areas permit sustainable extraction of natural resources by local communities, but little is known about how and why local people use biodiversity, particularly animal wildlife. We conducted a rapid appraisal of animal use by 236 households across Madagascar's rural Moramanga district to explore which wild faunal species are used by local people and for what purpose. Our results document a wide range of uses attributed to familiar wildlife groups, including lemurs, tenrecs, birds, geckos, chameleons, frogs and invertebrates. Uses include food, trade, medicine, and pest control among others. We conclude that conservation decisions concerning sustainable use in relation to livelihoods require an understanding of both the diversity of species used and the diversity of uses of species by local communities.

Abstract

The impact of climate change on Malagasy amphibians remains poorly understood. Equally, deforestation, fragmentation, and lack of connectivity between forest patches may leave vulnerable species isolated in habitat that no longer suits their environmental or biological requirements. We assess the predicted impact of climate change by 2085 on the potential distribution of a Critically Endangered frog species, the golden mantella (Mantella aurantiaca), that is confined to a small area of the central rainforest of Madagascar. We identify potential population distributions and climatically stable areas. Results suggest a potential south-eastwardly shift away from the current range and a decrease in suitable habitat from 2110 km2 under current climate to between 112 km2 – 138 km2 by the year 2085 – less than 7% of currently available suitable habitat. Results also indicate that the amount of golden mantella habitat falling within protected areas decreases by 86% over the same period. We recommend research to ascertain future viability and the feasibility of expanding protection to newly identified potential sites. This information can then be used in future conservation actions such as habitat restoration, translocations, re-introductions or the siting of further wildlife corridors or protected areas.

Abstract

The golden mantella (Mantella aurantiaca) is a critically endangered (CR) frog, endemic to the eastern rainforestsof Madagascar. Although the species is very popular in the pet trade and widely bred in captivity, its specific habitat requirements in the wild are poorly understood. Ten forested sites in the Moramanga district of Madagascar were surveyed for microhabitat and environmental variables, and the presence or absence of golden mantellas in quadrats positioned along transects in the vicinity of breeding sites. Mixed models were used to determine which variables best explained microhabitat use by golden mantellas. Sites where golden mantellas were found tended to have surface temperatures of 20-23 ˚C, UVI units at about 2.9, about 30 % canopy cover, and around 30 % herbaceous cover. Within sites, golden mantellas preferred microhabitats that had 70 % leaf litter coverage and relatively low numbers of tree roots. This information can be used to improve the identification and management of habitats in the wild, as well as to refine captive husbandry needs.

10. Understanding Livelihoods for Protected Area Management: Insights from Northern Madagascar

Abstract

Protected areas (PA) are the most common approach to conservation globally; however, their effectiveness is unclear when neighbouring human communities are highly natural resource dependent. While forest-based livelihoods provide important income for rural communities, destructive livelihoods such as charcoal production can also threaten the sustainability of PAs. We aimed to understand drivers of livelihood choices in communities surrounding a proposed PA threatened by charcoal production in northern Madagascar, to inform management strategies that promote forest conservation without negatively impacting local communities. We used semi-structured interviews and focus groups to understand local livelihood dynamics using the Sustainable Livelihoods Framework (SLF). Our findings showed charcoal production to be an important livelihood used to deal with annual food insecurity. Agricultural yields were limited by a lack of assets for clearing land and building protective fences. Households were also hesitant to invest in agriculture due to the perceived risks associated with unpredictable rainfall and cattle grazing. Furthermore, while fishing was an important livelihood for filling income gaps, declining catches due to overexploitation across the study region appeared to be increasing the need for charcoal production. While improvements to agriculture were perceived to be promising strategies for reducing forest-dependence, a landscape approach to conservation in the region will be necessary in order to promote sustainability of all livelihoods and to reduce overall pressures on forest resources.

Abstract

Five nocturnal lemur species, including Avahi laniger, Daubentonia madagascariensis, Cheirogaleus major, Lepilemur mustelinus, and Microcebus lehilahytsara, which are all clas sified as threatened, are present within Mangabe Reserve. This study aims to understand their habitat use (ecology) and their behaviors. The habitat used (substrate size, forest cover, microhabitats, tree size according to the CBH and height of the animal above the ground) by lemurs was studied within a 100m2 plot where the animals were found along the transect (1000m). The animals' behavior were recorded during 30 minutes to an hour of animal survey. 58.6 % of A. laniger, M. lehilahytsara, C. major and L. mustelinus were frequently observed and living inside the forest. Their habitats vary according to the species: M. lehilahytsara frequents small supports, using a substrate between 0.5 to 5 meters above the ground (level 1); L. mustelinus prefer large and medium supports, occurring on level 2 substrate; C. major can be seen on large supports, approximating level 4 substrate and A. laniger use large supports on level 2 substrates. These species of nocturnal lemurs generally use all parts of the vegetative systems of the tree; the animal is found either inside or at the periphery of the tuft such that: A. laniger and L. mustelinus select the trunks at rest and during movement; C. major and M. lehilahytsara frequently localized on branches during food intake. Four types of behavior and reactions towards humans were marked during the study; their activities are: resting, moving, grooming and feeding. The duration of the common "rest" activity varies from 20 - 29 minutes for these four species. These lemurs have been placed in higher threat categories due to increased human pressure (Tavy) in the Protected Area. These assemblages are closely related to undisturbed forests, even those adapted to open areas, and the restoration of their forest habitats will be recommended for their survival.
