Se analiza el papel que realiza una de las prácticas de conservación en los huertos de una comunidad mame en la Reserva de Biosfera Volcán Tacaná; Chiquihuite, Unión Juárez, Chiapas. Lo anterior, se llevó a cabo mediante la recolecta e identificación de las especies presentes en veinticuatro huertos de la comunidad y entrevistas semi estructuradas sobre el espacio de origen y el uso a la especie. Con esta información se elaboró una matriz de presencia-ausencia y una red de relaciones entre espacios, y se concluyó que existe una práctica de intercambio, principalmente entre los espacios huerto-montaña y huerto-huerto. La base de este intercambio es el uso y por ello la definición local del concepto de conservación, no se explica sin este concepto. INTERCHANGE OF PLANTS BETWEEN HOME GARDENS AND OTHER SPACES: A CONSERVATION STRATEGY FOR THE CLOUD FOREST OF THE TACANÁ VOLCANO IN CHIAPAS STATE, MEXICO? This paper analyzes the role played by one of the conservation practices carried out in the home gardens of a Mame community in the Tacaná Volcano Biosphere Reserve: Chiquihuite, in the Unión Juárez municipality of Chiapas State. This analysis was conducted through collecting and identifying the species present in 24 of the home gardens of the community as well as semi-structured interviews regarding the space of origin and use of the species. Based on this information, a presence-absence matrix was developed as well as a network of relationships between spaces. It was concluded that there is a practice of interchange, mainly between home garden and mountain, and between home garden and home garden. This interchange is based on use and therefore the local definition of conservation cannot be explained without this concept.
