“…Bark is one of the most important plant parts used as raw material in traditional medicine worldwide, as well as in urbanindustrial societies (Cunningham, 2014a; Senkoro et al, 2014; Mariot et al, 2014. Bark is also the most commonly extracted plant parts for biological activity tests in laboratories (Cunningham, 2014a; Kemppainen et al, 2014.…”

This study was carried out on a community-based and participatory field-based experiment, combining traditional ecological knowledge (TEK) and scientific knowledge, with the aim of defining criteria for sustainable harvest prescriptions for Garcinia lucida bark, focusing on its profitability, acceptability and ecological sustainability. Bark harvesting process was documented by monitoring 35 bark gatherers, who have provided accurate information on habitat, density, recruitment, seed predator of G. lucida species that matched well information found with ecological studies. TEK have provided useful information on the species geographical distribution that could serve as important tools in resource mapping and management. Based on the harvest practices experimental records and using TEK, bark gatherers have recommended a strip of 1/3 or 2/3 of tree circumference, by peeling off bark using machete, for household consumption; or ring-barked or felling trees for commercial proposes; a selection of larger trees and a repeat harvest on the same tree after complete bark recovery. Few gatherers, who started planting G. lucida in their coco-farm, showed real interest in applying these harvest prescriptions. However, the open-access status of wild stands constituted the most vulnerable point in applying these prescriptions. This study results have direct bearing on attempts towards sustainable resource use and adaptive management incorporating current ecological knowledge into participatory forest and resource management planning and regulations.

“…Cunningham and Mbenkum (1993) indicated that Prunus africana in Cameroon can achieved complete bark re-growth after ring barking. Bark regrowth from the edges recorded for Prunus africana trees was also found for Drimys brasiliensis (Mariot et al, 2014) and Himatanthus drasticus (Baldauf and dos Santos, 2014). However, over the two-year follow-up period, some trees are able to close the wound completely, suggesting a recovery time of about two years.…”

A b s t r a c t A r t i c l e I n f oPrunus africana is important for its bark used in the treatment of benign prostate hyperplasia in SouthWest Cameroon which has led to overexploitation of natural population of the species. Prunus africana is listed as an endangered species. Despite the relevance of bark, little information on the effects of some ecological and anthropic factors on the survival and bark recovery rate of Prunus africana is known. Debarking followed a combination of four factors: season of bark harvesting, three stem diameter classes and three intensities of trunk circumference debarked. After debarking, trees were trimestrially monitored for a two years period during which the survival of the tree and the speed of regeneration of the bark were recorded. Results show a dead rate of 13.33%. The rate of recovery of the bark at low altitude was about 21.27 cm/year. The best season for debarking was the rainy season (27.49 cm/year). Trees with a weak diameter (20-30 cm) showed a low rate of recovery (18.28 cm/year) and also those whose bark were peeled on a surface of 75 % of the tree's diameter (29.09 cm/year). These factors have important implications in drawing strategies for sustainable harvesting, management and conservation of this species.

“…Knowledge of reproductive biology in the context of floral morphology and interaction with biotic vectors is important for predicting species survivability (Faegri and Van der Pijl 1979, Rodríguez-Pérez 2005, understanding gene flow patterns and genetic differentiation of populations (O'Malley et al 1988, Bawa 1992) and supporting conservation and sustainable management efforts (Mariot et al 2014). Nevertheless, most V. curassavica studies have reported on its phytochemistry and pharmacology (Carvalho Jr. et al 2004, Fernandes et al 2007, Passos et al 2007, while neglecting important questions of autoecology (Opler et al 1975, Brandão et al 2015.…”

Varronia curassavica, a subshrubby medicinal species associated with restinga in the Atlantic Forest, has been exploited by local people and the pharmaceutical industry. Indeed, restingas have experienced a continuous process of degradation, and thus, with species and ecosystem both at risk, efforts to support conservation actions are required. The present study aimed to evaluate aspects of V. curassavica reproductive biology. To accomplish this, morphological characterization was performed by monitoring flowering events. The availability of nectar and pollen, as well as the frequency and behavior of floral visitors and dispersers, was also evaluated. This species exhibits both heterostyly and protogyny. Anthesis is diurnal, and flowers last less than a day. The high number of flower and fruit abortions suggests that mechanisms, such as self-incompatibility intra-morphs and easily detached flowers, contribute to reduced fruit production. The high diversity of floral visitors indicate a generalist pollination syndrome. Diptera, Hymenoptera and Lepidoptera were the main pollinators, and nectar was the main resource sought by these insects. Fruits were dispersed by birds and ants. It can be concluded that the interaction of V. curassavica with several species is a key factor in its own survival and for maintaining the biological diversity of restinga.
