RESUMO:

Ecosystem Services (SE) are characterized as tangible and intangible goods produced by ecosystems, used directly or indirectly in the search for human well-being. These services are the result of interactions between the elements of nature, and these function in an integrated way and are distributed heterogeneously in the environment, being necessary the delimitation of homogeneous units to facilitate the understanding of the dynamics of the systems. Within this approach, it is understood that the diversity of abiotic and biotic elements in the terrestrial surface provides the occurrence of important areas of ecological and social interest, and providing important services. Specifically in the case of Wetlands, among them, mangrove stands out as an environment where there are intense biological and geochemical processes that produce several SEs. In this research, the Tijupá river mangrove is one of the most extensive areas of this ecosystem located in the southeast portion of the Maranhão Island, being an area with few developed studies. O objetivo geral desta pesquisa foi analisar os serviços ecossistêmicos prestados pelo manguezal do rio Tijupá a partir da identificação dos serviços ecossistêmicos de provisão pelos usuários do manguezal. For this, compartmentalization of the area's mangrove into geoenvironmental units (apicum, mangrove forest, washing and tidal channels) and the geoenvironmental characterization of the respective units were carried out. Subsequently, the identification and classification of the Ecosystem Services of provision based on the Common Classification of Ecosystem Services (CICES) and the mapping of the SE of provision per environmental unit were carried out. The Tijupá river mangrove covers about 840 ha, most of this ecosystem represented by mangrove forest (708.9 ha) and washed (98.5 ha). The provision services identified in the area correspond to: fishing (e. g. catfish, mullet, siri), beekeeping (e. g. honey, propolis), wood converted into materials (e. g. fences, rafters), use of the fauna for fishing - bait (e. g. turu, tamaru, tide-tag), wood converted into energy (e. g. coal), with the potential SE being consumed by the communities in the area. Potentially service-oriented geoenvironmental units were the mangrove forest and tidal channels, where the forest stood out in the provision of materials and channels, in the provision of nutritional resources. Most of the services were indicated on the western margin of the mangrove, where there is a greater concentration of communities (e. g. Coquilho, Mato Grosso, Tajipuru and Caracueira) and land access routes. The analysis of these data provides support for mangrove management and the ways of using the mangrove resources. All of this information is relevant to mapping, since data on the distribution, intensity, and demand for services are important in identifying the most vulnerable areas of anthropogenic interventions and the losses and gains in SE provision. There is a need for further studies on the Tijupá river mangrove and other mangrove areas of the Island of Maranhão, fundamental for deepening knowledge about the dynamics of these ecosystems and the supply of SE (provision, regulation / maintenance and cultural), as well as for systematization data on the Ecosystem Services of the Mangroves of the Island of Maranhão.
