Impact of Women’s Harvest Practices onPandanus guillaumetiiin Madagascar’s Lowland Rainforests.Pandanus guillaumetii B.C. Stone is endemic to the east coast rainforests of Madagascar. The plant is an important non-timber forest product (NTFP) for the local population living near these forests, and its leaves are collected by women to be woven into mats. These mats have economic value and are also used for daily activities. At present, little is known about how local harvesting practices impact this plant species. In this study, we describe women’s local harvest practices and quantify their impact on the P. guillaumetii population. We carried out plant inventories as well as interviews and participatory observations with local people harvesting P. guillaumetii in two villages with different population densities in the Manompana region. Inventories were conducted at varying distances from the villages in order to better understand the influence of human pressure on the plant population. The results suggest that local communities apply practices that tend to minimize the harvest impact on the plant. Harvesting seems to have no effect on the actual density of P. guillaumetii. However, the availability of plants with leaves of sufficient quality for mat production is influenced by human pressure. Considering the decreasing number of plants suitable for handicraft, we assume that their availability in the long term may not fulfill the needs of the local people.

Impact de la récolte deP. guillaumetiipar les femmes dans les forèts pluviales de basse altitude de Madagascar.Pandanus guillaumetii B.C. Stone, une espèce endémique de Madagascar, se trouve dans les forêts ombrophiles du versant oriental de l’île. Les femmes des communautés vivant à proximité de ces forêts en utilisent les feuilles pour confectionner des nattes. Il s’agit de produits forestiers non ligneux en usage dans la vie quotidienne et qui ont une valeur économique. Les prélèvements de feuilles contribuent-ils à la raréfaction de l’espèce? A ce jour, peu de recherches ont été réalisées à ce sujet. Dans notre étude, nous décrivons les modes de prélèvement des feuilles de P. guillaumetii et cherchons à quantifier l’impact des prélèvements sur les populations de l’espèce. Nous avons réalisé des inventaires en forêt et effectué des interviews et des observations participatives avec les habitants de deux villages de la région de Manompana. Afin de saisir les effets de la pression humaine, nous avons effectué des inventaires à différentes distances des villages. Il ressort des résultats que les pratiques de prélèvement des feuilles par la population locale tendent à minimiser l’impact de la récolte. Les prélèvements ne paraissent pas avoir d’effet sur la densité de la population de l’espèce. Néanmoins, les plantes fournissant des feuilles convenant à la confection de nattes sont moins abondantes à proximité des villages. Considérant la diminution du nombre d’individus se prêtant à un usage artisanal, nous estimons qu’à long terme, les besoins de la population ne pourront plus être satisfaits.
