It is true of the babassu palm, which can be considered, paradoxically, a natural resource by the "Interstate Movement of Babassu Fruit Breaker Women" or as native weed by land owners-farmers. To manage potential conflict of land uses, we study here the current density of this palm tree in different habitats, based on a combination of field data and remote sensing data. Firstly, we checked that the field survey methodology (i.e., counting free-trunk palm trees over 20 cm in circumference) provides density values compatible with those stemming from satellite images interpretation. We can see then that, a PA-Benfica Brazilian territory revealed an average density of the babassu lower in pastures (2.86 ind/ha) than in the dense forest (4.72 ind/ha) from which they originate and than in fallow land (4.31 ind/ ha). We analyze in detail density data repartition in three habitats and we discuss results from the literature on the density of this palm tree versus its resilience at different developmental stages after forest clearing, depending on anthropogenic -or not- factors, including solar radiation, fire, weeding, clear cutting, burying fruit, and competition with forage grass. All these results can be exploited for the design of future management plans for the babassu palm and we think that the linked methodology and interdisciplinary approach can be extended to others palms and trees species in similar problematic issues. specialized PHYTOECOLOGIE IMAGE SATELLITE PHOTOINTERPRETATION ANALYSE STATISTIQUE FORET DENSE PATURAGE DYNAMIQUE DE VEGETATION GESTION DE L'ENVIRONNEMENT RESOLUTION SPATIALE BIODIVERSITE RESILIENCE PALMIER BRESIL AMAZONIE 076BOTA05 126TELAPP08 082VEGET 61 2 321-336 [+ Correction 337-338] 2018 0364-152X https://www.documentation.ird.fr/hor/fdi:010072188 10.1007/s00267-017-0965-6 0364-152X [F B010072188] https://www.documentation.ird.fr/hor/fdi:010072188 https://www.documentation.ird.fr/intranet/publi/depot/2018-02-19/010072188.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2018-02-14 2026-05-12 fdi:010072188 fre
