title: Replication data for:  Developing indicators of economic value and biodiversity loss for rubber plantations in Xishuangbanna, southwest China: A case study from Menglun township.

description: Xishuangbanna has been largely transformed from biodiverse natural forests and mixed-use farms into monoculture rubber plantations in just twenty years. This conversion has expanded into forests previously protected by the community and onto marginal sites at high-elevation. Market-based ecosystem payments, especially carbon financing, are potential tools to prevent further forest loss in China. Here, we compare rubber net present value (NPV), carbon sequestration, and seed-plant species diversity for Xishuangbanna given three land-use scenarios: Business-As-Usual (BAU), Economic Oriented Scenario (EOS) and Conservation Oriented Scenario (COS) using a previously published spatial map of rubber profitabilit
y. The EOS achieved the greatest rubber profit but caused substantial reductions in natural forest area, biodiversity and carbon stocks. The EOS also requires substantial immigration of workers into a remote and ecologically important region with little social infrastructure for basic security, food security, health-care and education, causing frequently ignored costs. As expected, the COS will maintain the highest levels of natural forest area, sequester 57% more carbon, and 71% more biodiversity than EOS. Given the conservation value of the carbon stores and rich biodiversity residing in Xishuangbanna's natural forests, reducing rubber NPV only marginally would probably cost less than attempting to recover these resources. We recommend that rubber plantations be limited to established, productive lowland areas whilst protecting intact high-elevation forest and reforesting low-productivity plantations. These actions will enhance carbon sequestration and biodiversity conservation.  Management policies focused solely on profits, like the EOS scenario, will fail to sustain the entire range of natural resources and ecosystem services. The prices in the carbon market would have to be considerably larger than they are currently to compete with the profitability of rubber.

title: Replication data for: Will funding to Reduce Emissions from Deforestation and (forest) Degradation (REDD+) stop conversion of peat swamps to oil palm in orangutan habitat in Tripa in Aceh, Indonesia?

description: Tripa is the last remaining peat-swamp forest that harbours a poten
tially viable Sumatran orangutan (Pongo abelii) sub-population in a formally but not effectively protected area. It appears to be a simple showcase where current efforts to financially support reducing emissions from deforestation and forest degradation (REDD+) converge with biodiversity and social co-benefits. In practice, however, the situation is more complex. REDD+ efforts interact with global palm oil trade and regulatory approaches (the moratorium) to achieve national goals for emissions reduction under umbrella of nationally appropriate mitigation actions (NAMA). To contextualize this debate, we assessed (i) land-use history and formal basis of palm-oil companies' rights; (ii) carbon (C) stocks, historical emission levels and potential emissions that can be avoided; (iii) economic benefits of land-use options and opportunity costs of avoiding emissions; (iv) biodiversity and environmental services; and (v) alternative options for "high C stock development" and employment generation. Natural forest cover declined (54 % in 1995, 18 % in 2009) while oil palm increased 4 - 39 %. Aboveground C stocks decreased from 148 Mg ha -1 in 1990 to 61 Mg ha-1 in 2009, leading to average annual emissions of 14.5 Mg (carbon dioxide) CO2e ha -1  year-1. While 41 % of these emissions yield less than American Dollar (USD) 5 of current economic benefits per Mg CO2e emitted and might be compensated by REDD+, nearly all new emissions derive from a breach of existing laws, regulations and voluntary palm-oil standards. Substantial investment in alternative employment is needed, rather than carbon payments per se, to support livelihoods in a low carbon emissions economy

title: Replication data for: Oroquieta City Households’ Willingness to Pay for Coastal Biodiversity Conservation

description: Over the years, ecosystem services have been undervalued since regarded as public good. Low appreciation on the benefits provided by the ecosystem has led to the overutilization of resources, causing negative impacts to biodiversity and environment. In the Philippines, biodiversity conservation has not been given enough priority, and has been beset with various problems such as insufficient funding. This usually applies in coastal communities, where majority of community members have low capacity to contribute monetarily. However
, the rising occurrence of climate-related phenomena also increases the awareness of communities and their willingness to contribute to environmental conservation activities such as Payments for Ecosystem Services (PES). This study aimed to value the coastal conservation activities from households of Oroquieta City through contingent valuation method. The computed mean willingness to pay for coastal conservation using parametric estimation was PhP 30.39, wherein the estimated mean willingness to pay translates to 0.23% of their average income. Potential revenue to be collected annually could amount to PhP 1.8 million. In five years, the total collection could reach PhP 9 million, which is also substantial to make the biodiversity conservation activities sustainable. The estimation of this study could serve as basis for implementation of PES in the the coastal communities for sustainable biodiversity conservation.

title: Replication data for: Variation in wood color among natural populations of five tree and shrub species in the Sahelian and Sudanian ecozones of Mali

description: There is very little published information about variation in the wood properties of African tree species. To expand markets for wood products from these species, we must understand the factors that affect wood properties, and select the best species and sites to produce wood with the preferred properties. Wood color may be affected by edaphic and climatic conditions, tree age, wood density, and other biological and environmental factors. The major objective of this research was to determine if the mean and variability of wood color variables (L*, a*, and b*) of Balanites aegyptiaca (L.) Delile, Combretum glutinosum Perr. ex DC., Guiera senegalensis J.F. Gmel., Piliostigma reticulatum (DC.) Hochst., and Ziziphus mauritiana Lam. trees varied among regions, soil types, land-use types, and terrain types; and were linearly related with geographical coordinates and mean annual rainfall in the Sahelian and Sudanian ecozones of Mali. Correlations were also investigated among color variables and between wood density and color variables. Results indicated that there was considerable intraspecific variation in wood color variables due to all factors except land-use type; variation patterns were similar for some wood color variables and species, but there were notable differences among some species; and correlations amo
ng wood color variables and wood density differed among some species.

title: Replication data for: Seasonal Response of Grasslands to Climate Change on

description: Background: Monitoring vegetation dynamics and their responses to climate change has been the subject of considerable research. This paper aims to detect change trends in grassland activity on the Tibetan Plateau between 1982 and 2006 and relate these to changes in climate. Methodology/Principal Findings: Grassland activity was analyzed by evaluating remotely sensed Normalized Difference Vegetation Index (NDVI) data collected at 15-day intervals between 1982 and 2006. The timings of vegetation stages (start of green-up, beginning of the growing season, plant maturity, start of senescence and end of the growing season) were assessed using the NDVI ratio method. Mean NDVI values were determined for major vegetation stages (green-up, fast growth, maturity and senescence). All vegetation variables were linked with datasets of monthly temperature and precipitation, and correlations between variables were established using Partial Least Squares regression. Most parts of the Tibetan Plateau showed significantly increasing temperatures, as well as clear advances in late season phenological stages by several week
s. Rainfall trends and significant long-term changes in early season phenology occurred on small parts of the plateau. Vegetation activity increased significantly for all vegetation stages. Most of these changes were related to increasing temperatures during the growing season and in some cases during the previous winter. Precipitation effects appeared less pronounced. Warming thus appears to have shortened the growing season, while increasing vegetation activity. Conclusions/Significance: Shortening of the growing season despite a longer thermally favorable period implies that vegetation on the Tibetan Plateau is unable to exploit additional thermal resources availed by climate change. Ecosystem composition may no longer be well attuned to the local temperature regime, which has changed rapidly over the past three decades. This apparent lag of the vegetation assemblage behind changes in climate should be taken into account when projecting the impacts of climate change on ecosystem processes.

title: New species of Phallus from a subtropical forest in Xishuangbanna, China

description: Seven collections of Phallus species were made in surveys of a subtropical forest in Xishuangbanna in Yunnan Province, China, during the wet season of 2012. Macro and micro characters, together with nrITS sequence data, were used to separate the collections into three species. Phallus mengsongensis and P. serrata are introduced as species new to science, while a further Phallus species is described, but not formally introduced, due to paucity of material. Macro and micro descriptions, colour photographs, line drawings and nrITS phylogenetic data for all three species are provided, which are discussed in relation to similar species in these genera.

title: Replication data for: Carbon sequestration by Dacryodes edulis: implication for the opportunities of Payment for Environmental Services (PES)

description: In order to fight against climate change through the development of profitable systems of production, it was necessary to study the influence of propagule of  Dacryodes edulis on the carbon sequestration in  plantations containing African Plum and to deduce their opportunities to the PES. The present study was carried out in the experimental plots of ICRAF at Mbalmayo. From the data collected, the results have shown that the average biomass, carbon stock and CO2 sequestered are higher in cutting's plots (268.1 ÃÂ± 191.3) compared to the populations of marcots (217.4 ÃÂ± 127.9) and of seedlings (131.0 ÃÂ± 93.63). No significant difference was observed between CO2 sequestered in the population of cuttings and marcots (F2; 85 = 5.256; ÃÂ = 0.569 > 5%). An evaluation of the potential incomes that could be generated from the different types of propagules gave 129,595 Fcfa/ha, 105,085 Fcfa/ha and finally 63,320 Fcfa/ha for the  population of cuttings, marcots and seedlings respectively. Theimplication for theopportunities related to the PES via the CDM increase with the capacity of CO2 sequestration indicates that the populations of trees from cuttings will offer more incomesin the case of carbon marketthan those from other propagules.

title: Antecedent and effect of group sales on supply chain performance: The Case of Kola production and Marketing in Cameroon

description: Kola plays an important role in the livelihoods of people in the North West region of Cameroon. However, the potential benefits of the product have not been fully exploited due to many problems including ineffective marketing techniques. In an attempt to address this problem, some organisations like the World Agroforestry Centre (ICRAF) have facilitated the producers of kola to embark on group sales as a means to improve their marketing performance. During the first 5 years of implementation of this programme, there was no clear picture about the impact of the marketing intervention programme on the marketing performance of the farmers. This paper discusses the main antecedents and producers’ perception of the effects of the group sales on the supply chain performance of kola producers in Cameroon. Using open ended interviews with 50 farmers, the paper reveals that group sales has the potential to improve kola supply chain performance through increase in prices, quantity harvested and sold, and increase in number of producers involved in the group.

title: Replication data for: Altitudinal variation and conservation priorities of vegetation along the Great Rift Valley escarpment, northern Ethiopia

description: Understanding plant species distribution patterns along environmental gradients is fundamental to managing ecosystems, particularly when habitats are fragmented due to intensive human land-use pressure. To assist management of the remaining vegetation of the Eastern Afromontane Biodiversity Hotspot, plant species richness and diversity patterns were analyzed along the main elevation gradient (1,000â2,760 m) of the Great Rift Valley escarpment in northern Ethiopia, using 29 plots established at 100-m elevation intervals. A total of 129 vascular plant species belonging to 59 families was recorded. Species richness and diversity showed a hump-shaped relationship with elevation, peaking at mid-elevation (1,900â2,200 m). Beta diversity values indicated medium species turnover along the elevation gradient and were lowest at mid-elevation. Elevation strongly partitioned the plant communities (r = 0.98; P\0.001). Four plant communities were identified along the elevation gradient: Juniperus proceraâClutia lanceolata community (2,400â2,760 m), Abutilon longicuspeâCalpurnia aurea community (1,900â2,300 m), Dracaena ombetâ Acacia etbaica community (1,400â1,800 m), and Acacia melliferaâDobera glabra community (1,000â1,300 m). To optimize conservation of species and plant communities, it is recommended that a conservation corridor be established along the elevation gradient that includes all four plant communities. This strategyâin contrast to creating single isolated reserves in zones with high species richnessâis necessary for the habitat protection of species with narrow elevational ranges, in particular the globally endangered Nubian dragon tree (Dracaena ombet).

title: Replication data for: Predicting geographic distribution and habitat suitability due to climate change of selected threatened forest tree species in the Philippines

description: Climate change is projected to alter the geographic distribution of forest ecosystems. This study aimed to evaluate the consequences of climate change on geographical distributions and habitat suitability of 14 threatened forest tree species in the Philippines. Based on the principle of maximum entropy, it utilized a machine algorithm called Maxent to estimate a target probability distribution and habitat suitability of the selected species. Threatened forest tree species occurrence records and sets of biophysical and bioclimatic variables were inputted to Maxent program to predict current and future distribution of the species. The Maxent models of the threatened species were evaluated using Receiver Operating Characteristics Area Under Curve (ROC AUC) and True Skill Statistics
(TSS) tests which revealed that the models generated were better than random. The Maxent models ROC AUC values of the 14 species range from 0.70 to 0.972 which is higher than 0.5 of a null model. Based on TSS criteria, Maxent  models performed good in two species, very good in ten species, and excellent in two species. Seven species (Afzelia rhomboidea; Koordersiodendron pinnatum; Mangifera altissima; Shorea contorta; Shorea palosapis; Shorea polysperma; Vitex parviflora) were found to likely benefit from future climate due to the potential increase in their suitable habitat while the other seven species (Agathis philippinensis; Celtis luzonica; Dipterocarpus grandiflorus; Shorea guiso; Shorea negrosensis; Toona calantas; Vatica mangachapoi) will likely experience decline in their suitable habitat. This study provided an initial understanding on how the distribution of threatened forest trees will be affected by climate change in the Philippines. The generated species distribution models and habitat suitability maps could be used as basis in formulating appropriate science-based adaptation policies, strategies and measures that could enhance the resilience of those threatened forest tree species and their natural ecosystems to current and future climate.
