The tropical dry forest is an ecosystem under strong human pressure. It is found both inland and on coastal dunes. The objective of this research is to identify native tree and palm species growing on dunes that are used by local communities. In this research we carried out surveys and interviews among residents of San Isidro and Colonia La Mancha, in the coast of Veracruz on the use of trees of the tropical dry forest on dunes. Among the 55 registered species, Cedrela odorata, Diphysa robinioides, Enterolobium cyclocarpum, Bursera simaruba, Gliricidia sepium, Tabebuia rosea, Chrysobalanus icaco, Guazuma ulmifolia, Acacia cochliacantha, Brosimum alicastrum, Bumelia celastrina, Cocos nucifera, Maclura tinctoria, Piscidia piscipula, Spondias mombin and Ficus spp. were mentioned by more people. Eighteen uses were recorded, being the most frequent construction of houses (119 mentions), posts for fences and live fences (99), firewood (72) and food (48). Four of the uses mentioned refer to environmental services provided by these plants in the dunes. The species with higher number of uses is Gliricidia sepium and Bursera simaruba is the species in which more parts are used, followed by Gliricidia sepium, Guazuma ulmifolia and Brosimum alicastrum. We also inquired about the parts of the tree being used, the frequency, their sale and local price. Based on the results we suggest a group of species that can be used to increase species tree richness in the secondary growths and grassland on dunes, which will provide wood, forage, etc., to the local inhabitants and help maintain the tree cover of the dunes.
