“…Taking into account the area impacted during logging, a rosewood revenue of US$31-76 per hectare is achieved (based on Randriamalala & Liu 2010). Rosewood trafficking has increased significantly since the 2009 coup as a result of political instability and rising corruption and has brought some species near to extinction (Barrett et al 2010). In the two CBAs summarized earlier, the foregone benefits from timber extraction represent the most important opportunity costs on the regional and national levels (Kremen et al 2000;Hockley & Razafindralambo 2006).…”

“…In south-western Madagascar, bushmeat hunting is a secondary activity and probably has an important function as a safety net (Gardner & Davies 2014). Although sustainable wildlife hunting can potentially generate long-term benefits for the local population, hunting has increased and is a major conservation concern (Barrett et al 2010;Randrianandrianina et al 2010). In addition, many of Madagascar's unique species achieve very high prices on the international pet market.…”

Global benefits and local costs – The dilemma of tropical forest conservation: A review of the situation in Madagascar

2016

SUMMARYDeforestation is one of the most important conservation problems in tropical developing countries, even though cost-benefit analyses consistently show that forest conservation is economically beneficial. In Madagascar, deforestation continues at alarming rates despite numerous initiatives of international donors to increase incentives for local households to support forest conservation. In this literature review, we contrast cost-benefit analyses for forest conservation with: (1) the actual burdens and (2) the actual gains of forest conservation for rural households, generated mainly in the context of conservation projects. We show that approaches to generating direct benefits deliver less value than expected for rural communities; the benefit transfer mechanisms are insufficient as the majority of benefits are captured by other stakeholders, and increased benefit transfer is limited by structural and institutional limitations in local communities, valuation chains and in terms of governance failure at higher levels.

“…Also the wood of a number of Dalbergia trees is highly estimated as high-quality and high-value timber, such as the rosewoods, which include the Brazilian rosewood (Dalbergia nigra), Indian rosewood (Dalbergia latifolia), Madagascar rosewood (Dalbergia maritima) and Huanghuali rosewood (Dalbergia odorifera). The heartwood of these rosewoods is exceptionally dense, non-porous and durable, and it is suitable for producing carvings, furniture, music instruments and ornaments (Barrett et al 2010;Hassold et al 2016).…”

“…Nevertheless, the protected species are still endangered by targeted and illegal logging. Most logged rosewood timber is shipped to China, one of the world's largest consumers of tropical hardwoods and rosewood furniture (Barrett et al 2010). The authentication and legal control of illegal transport of the endangered wood species is based on the morphological characteristics (Hartvig et al 2015), microscopic structures (Yu et al 2016), or chemical and physical characteristics (Rana et al 2008;Cristina et al 2011;Sandak et al 2015;Wang et al 2016;Wu et al 2017).…”

Abstract:The genus Dalbergia contains approximately 250 species with many valuable trees being destroyed by targeted and illegal logging. DNA barcoding is a reliable method for the molecular identification of different species and resources conservation. In the present study, the specimen discrimination ability of internal transcribed spacer (ITS), matK, rbcL and psbA-trnH barcoding were tested on Dalbergia sequences, downloaded from the National Center for Biotechnology Information (NCBI), and the combined barcoding ITS + matK + rbcL was used to identify unknown specimens. It was found that ITS + matK + rbcL have good discrimination rates based on the analysis methods best match (BM) and best close match (BCM). These barcodes also have the best performance concerning barcode gap distribution, and are able to discriminate unknown specimens from South-China. Furthermore, it was demonstrated that D. tamarindifolia and D. rubiginosa are also relatively close to sister-species D. pinnata and D. candenatensis within the phylogenetic Dalbergia tree. Considering the overall performance of these barcodes, we suggest that the ITS + matK + rbcL region is a suitable barcode for identifying Dalbergia species.

Do functional traits offset the effects of fragmentation? The case of large‐bodied diurnal lemur species

Primates worldwide are faced with increasing threats making them more vulnerable to extinction. Anthropogenic disturbances, such as habitat degradation and fragmentation, are among the main concerns, and in Madagascar, these issues have become widespread. As this situation continues to worsen, we sought to understand how fragmentation affects primate distribution throughout the island. Further, because species may exhibit different sensitivity to fragmentation, we also aimed to estimate the role of functional traits in mitigating their response. We collated data from 32 large-bodied lemur species ranges, consisting of species from the families Lemuridae (five genera) and Indriidae (two genera). We fitted Generalized Linear Models to determine the role of habitat fragmentation characteristics, for example, forest cover, patch size, edge density, and landscape configuration, as well as the protected area (PA) network, on the species relative probability of presence. We then assessed how the influence of functional traits (dietary guild, home range size) mitigate the response of species to these habitat metrics. Habitat area had a strong positive effect for many species, and there were significantly negative effects of fragmentation on the distribution of many lemur species. In addition, there was a positive influence of PAs on many lemur species' distribution. Functional trait classifications showed that lemurs of all dietary guilds are negatively affected by fragmentation; however, folivore-frugivores show greater flexibility/variability in terms of habitat area and landscape complexity compared to nearly exclusive folivores and frugivores. Furthermore, species of all home range sizes showed a negative response to fragmentation, while habitat area had an increasingly positive effect as home range increased in size. Overall, the general trends for the majority of lemur species are dire and point to the need for immediate actions on a multitude of fronts, most importantly landscape-level reforestation efforts.
