title: Agroforets a base de cacaoyers au Sud du Cameroun. croissance, developpement des arbres et influence sur les jeunes cacaoyers

description: Theobroma cocoa L. est l’une des principales cultures de rente pratiquées dans la zone forestière humide du Cameroun. Il contribue pour plus de 50% par an au budget des ménages. La baisse du prix du cacao sur le marché mondial dans les années 90 a amené les planteurs à diversifier les cultures dans leurs cacaoyères en y intégrant des arbres améliorés. Cependant, l’absence d’un modèle-type d’intégration qui soit le plus bénéfique aux arbres et aux cacaoyers et qui soit le plus économiquement rentable reste le problème majeur auquel font face les cacaoculteurs. Cette étude vise à déterminer un modèle idéale d’agroforêt à base de cacaoyers qui offre un développement optimal aux espèces en association et procure aux paysans de meilleurs revenus. Un modèle en trois stra
tes auxquelles appartiennent les arbres à l’âge adulte est comparé aux plantations pures de cacaoyers (témoin): la strate inférieure (marcottes de Dacryodes edulis et greffes d’Irvingia gabonensis), la strate moyenne (semis, boutures de D. edulis et greffes de Ricinodendron heudoletii) et la strate supérieure (semis et boutures de R. heudoletii). L’essai est conduit suivant un dispositif en blocs avec 4 répétitions dans chacune desquelles les traitements sont alloués de manière aléatoire. Chaque parcelle enrichie d’une superficie de 1728 m2 comporte 12 arbres plantés à 12m x 12m, en association avec 192 plants de cacaoyers disposés à 3m x 3m. La hauteur des plants, le diamètre au collet, le développement de la couronne et les coûts d’exploitation sont évalués et comparés annuellement. Les résultats à la troisième année de plantation n’ont révélé aucune différence significative du point de vue développement ni des arbres, ni des cacaoyers dans les 3 strates comparées aux parcelles témoins. Les arbres des strates inférieures, moyennes et supérieures mesurent respectivement 1,14±0,13m; 1,43±0,20m et 1,65±0,23m de haut et les jeunes cacaoyers 0,98±0,05m; 1,09±0.05m et 1,1±0,04m. Les coûts d’installation sont en cours d’évaluation mais déjà il est important de noter que les différentes strates n’ont pas d’influence sur la croissance du cacaoyer trois ans après plantation.

title: Replication Data for: Distribution and in situ conservation of a relic Chinese oil woody species Xanthoceras sorbifolium (Yellowhorn)

description: To understand the contemporary and anticipated future (future 30–50 years) distribution of Chinese wild yellowhorn (Xanthoceras sorbifolium Bunge) and to improve the species’ in situ conservation strategy within the network of China’s National Nature Reserves (NNR), we used BiodiversityR to predict the species’ distribution utilizing the “always-suitable” map concept. We then delineated the always-suitable distributions with the existing NNRs to identify potential conservation areas using an approach that concurrently considered spatial distribution, gap analysis, the role of climate change, and economic analyses. Seven bioclimatic variable predictors and 12 environmental niche modelling submodels successfully contributed to the final model assembly (AUC = 0.916,  = 0.398). The species range delineation indicated that 71 of the 427 NNRs were included in the always-suitable area, accounting for 26 007 km2 (1.58%) of the species total distribution. This mapping endeavour highlighted the negative impact of climate change with a projected 15%–20% habitat decline and expected species’ distribution centers shifting from the country’s northwest to the southeast. Our results predict the continuous deterioration of X. sorbifolium because of its existing utilization as an oil source and its increased bioenergy potential. The adoption of a flexible management strategy embracing acceptable trade-offs between conservation and utilization within China’s NNRs could effectively alleviate the expected species decline.

title: Replication data for: Characterisation of Dacryodes edulis fine roots distribution considering propagule type, soil depth and lateral distance from the tree colar

description: Below ground tree growth attributes determine whether associations will be complementary or competitive in an agroforestry context. A study on fine root (d B 2 mm) distribution patterns of Dacryodes edulis based on root density (RD), root length density (RLD) and root weight density (RWD) was conducted to evaluate the effect of propagation methods on rooting distribution. Results showed that D. edulis trees of seed origin had greater RD (P B 0.001) than trees of vegetative origin (cuttings and marcots) in the upper soil stratum (0–30 cm). Similarly, in the uppermost soil stratum (0–10 cm), RLD and RWDs varied significantly (P\0.01). Trees of seed origin had an exponential distribution pattern for fine RD, RLD and RWD with depth to 80 cm. In contrast, the distribution pattern of fine roots of trees of vegetative origin (cuttings and marcots) were quadratic for the same variables which increased in the 20–30 cm soil depth stratum before declining steadily to a depth of 80 cm. The findings of this study suggest that D. edulis trees of vegetative origin (cuttings and marots) are likely to be less competitive than trees of seed origin when intercropped with shallow-rooted annual plants in an agroforestry system for belowground resources.

title: Replication data for: Determinants of farmersâ tree  planting behavior in the North West region of Cameroon: the case of Prunus Africana.

description: Poor households in Cameroon rely on trees and tree-based products like the bark of Prunus africana(Hook.f.) Kalman (Rosaceae) (henceforth called Prunus) that are harvested from the wild.Due to unsustainable bark harvesting practices, the European Union, which is Cameroonâs main market for Prunus bark, banned its importation. To reduce pressure on existing natural stock, research and development organizations introduced innovations to encourage farmers to plant Prunus trees. The research reported in this article analyses farmer characteristics which influence their Prunus planting behaviour, and examines their main problems. Results from interviewing 154 farmers who have been trained on tree domestication techniques suggest that male farmers and those who bought their land have planted Prunus in their farms. We conclude that Prunus information and planting campaigns can be effective if they are accompanied with policies which influence better prices, supply of seeds and seedlings, and address land tenure issues.

title: Replication data for: Methodological approaches for the selection of genotypes in a progeny trial of Dacryodes edulis (G. Don) H. J. Lam in Cameroon

description: The World Agroforestry Centre (ICRAF) initiated a program in Cameroon for the selection of improved genotypes of Dacryodes edulis for domestication. There are major challenges in such selection because superior performance of individual trees may be based on site conditions rather than on genetic differences. Open-pollinated seeds were collected from mother trees in four provenances in Cameroon and planted in a progeny trial at Minkoameyos, Cameroon. Progeny from the same mother tree are referred to as family. After one year of growth in the field, growth traits were measured annually for five years and fruit traits were measured in two successive years. Three methodological approaches were investigated: family and within-family selection (combined selection), ranking for phenotypic selection and correlation for multi-trait and early selection. Variation in growth and fruit traits among families was not significant for most provenances, indicatin
g that family selection would not be effective for the selection of genotypes in the trial. Phenotypic selection resulted in the retention of a small number of individuals of all families in the trial. There were strong positive correlations between fruit traits and between fruit and growth traits, while negative correlations were found between fruit traits and yield. The correlations indicate that selecting for one fruit trait may also improve the other fruit traits but reduce fruit yield. Positive and significant juvenile-mature correlations for growth were also found in this trial, indicating that early selection may be possible based on growth. Based on these results, phenotypic selection is recommended in the progeny trial for the domestication program in Cameroon and further research on early selection is needed as the trial advances in age.

title: Replication Data for: Local Perception on Land Use Systems and Biodiversity in a Rubber Plantation of North Sumatera.

description: Forest area in North Sumatera has declined since many years ago and have changed to more intensive land use systems, e.g. oil palm plantation, rubber monoculture plantation and smallholder. The study of local perception on land use systems and biodiversity was conducted in six villages in Simalungun district, Asahan district, and Serdang Berdagai district, North Sumatera province, to understand local preferences for land-use systems, local perceptions on land-use functions, and values on biodiversity, using Multidisciplinary Landscape Analysis (MLA) approach. The study showed that smallholder rubber and oil palm were the main sources of livelihoods in almost every village, since the two land use systems were important as cash income source. All participants perceived that rubber agroforest was the most important land use, as it could provide sources of income, food and environment values. Peoples understanding on biodiversity was closely associated with livelihood patterns and social life, as biodiversity contributed to their daily needs, and related to specific knowledge. All rubber plots under mixed and monoculture systems were perceived as good value in preventing erosion, while oil palm plots were of relatively low value. Interestingly, people also understood that forest had the highest function as an erosion control as these area are prone to soil erosion due to topography. Local people classified flora and fauna diversity based on their functions, such as food, source of income, fuelwood, construction, medicine, fodder, handycraft and tools, and erosion control. They noticed different biodiversity occured in different land-use types. Rubber agroforests provide all needs, e.g. goods and services, for local communities

title: Replication Data for Changing perceptions of forest value and attitudes toward management of a recently established nature reserve: A case study in Southwest China.

description: Identifying the main sources of conflict and understanding the relationships between protected areas and local communities are critical to conflict resolution related to protected area management. We surveyed and assessed the perceptions of local people related to forest values of the Bulong Nature Reserve (BNR), Yunnan, China, and their attitudes toward forest management of the recently-established nature reserve. Factors influencing the differences in perceptions and attitudes were investigated. Our results indicated local residents preferred the economic value of forests, and they perceived more forest values after reserve establishment than before, especially for ecological services. Interviewees believed the value of the forests have increased, and predicted that the forest will have increased importance to their livelihoods and health in the future. Nonetheless, the majority of interviewees were dissatisfied with current reserve management. Variation in these perceptions and attitudes were related to several social variables: age, gender, education, and distance from the reserve. Embedding the findings of the present study, specifically the perceptions and attitudes of local people, into management guidelines for mitigation of potential conflicts is proposed and should help managers to achieve biodiversity-related goals. This study offers new insights related to the identification of the underlying sources of conflict in forest management and provides a better understanding of the relationship between local people and protected areas. The study also contributes to the literature on forest values of indigenous populations by examining those of remote, rural populations in China.

title: Replication data for: Simulating impact land use change watershed services in Sasumua Watershed using SWAT

description: Land use change has a major influence on the capacity of watersheds to produce watershed services such asimproving water quality and flood mitigation. The objective of this study was to simulate the effect of land usechange on the sediment and water yield in Sasumua watershed, Kenya using SWAT model. The SWAT modelwas calibrated and validated using recorded reservoir data. The validated model was then used to simulatewater and sediment yield under three scenarios of runoff curve number CN (improved land surface conditionCN-6, base case, degraded land surface condition CN+ 6). The CN was used as a surrogate to represent landsurface treatments that influence generation of surface runoff following rain events. The coefficient ofdetermination from the calibration of the model was 0.6 and 0.5 for the validation. An increase in CN by 6(scenario CN+ 6) units in the agricultural part of the watershed, increased the sediment loading to the streamsby 53.6% while a reduction by 6 units (scenario CN-6) reduced sediment loading by 34.3%. Scenario CN-6resulted in a 28.5% decrease in surface runoff, a 13.8% increase in base flow and a slight decrease in totalwater yield of 1.2%. On the other hand, scenario CN+ 6 increa
sed the surface runoff by about 44%, reducedbase flow by 10.5% and increased the water yield by 6.5%. Improvement in land surface condition thatenhances infiltration is a feasible conservation measure to reduce soil erosion and subsequent sedimentation ofthe rivers and the reservoir. CN-6 can be achieved through terracing, contour farming, grass strips, better cropresidue management and well managed grazing

title: Replication Data for: Can gender appreciation of trees enhance landscape multifunctionality? A case of smallholder farming systems on Mount Elgon

description: Trees provide livelihood support functions and environmental services that contribute to the multifunctionality of landscapes. The presence or absence of trees is influenced by the interactions between ecological, social-economic and cultural elements. The role of gender in land use perceptions and changes involving trees have received little attention. In Africa, gender differentiated access, use and decision-making related to trees are common features. Divergent control and access to resources by men and women are likely to influence their perceptions and preferences for trees in the landscape. This paper discusses the results of an assessment of men's and women's appreciation of trees in Kapchorwa District, on the slopes of Mount Elgon in Uganda. While men and women were found to have differences in their access to tree products, decision-making powers and agroforestry practices, their land use preferences and perceptions of environmental services were similar. The paper provides recommendations on community forest management, agroforestry programmes and conservation agreements.
