RESUMO:

The Açu National Forest (FLONA de Açu), located in the Brazilian semiarid region, is a sustainable-use conservation unit where trails are used for visitor activities, creating a need for information to support public-use planning and management. This research aimed to analyze the landscape and carrying capacity of the FLONA de Açu trails to contribute to visitor planning within the unit. The study integrated bibliographic and documentary research with geoprocessing and fieldwork. The unit's geo-environmental aspects were characterized, and the Coral, Caatingueira, and Principal trails were analyzed regarding physical characteristics, soil particle size distribution, and land use and cover. Visitor capacity was determined using the method proposed by Cifuentes et al. (1999)—calculating Physical Carrying Capacity, Real Carrying Capacity, and Tourist Carrying Capacity—while incorporating correction factors and Management Capacity. Additionally, the Maximum Operational Capacity was estimated based on available conditions for group supervision. The results revealed a landscape characterized by a predominantly sedimentary substrate associated with the Açu Formation, low elevations, and terrain ranging from flat to undulating. Within the visitor areas, the trails exhibited minor elevation changes and variations in soil particle size; coarser materials were more prevalent on the Coral and Caatingueira trails, whereas the sand fraction predominated on the Principal Trail. Land use and cover were overwhelmingly dominated by vegetated areas. The unit's Management Capacity was estimated at 80%, resulting in Tourist Carrying Capacities of 388 visitors/day for the Coral Trail, 680 for the Caatingueira Trail, and 750 for the Principal Trail. However, operational conditions reduced these figures to Maximum Operational Capacities of 360, 320, and 240 visitors per day, respectively, highlighting the influence of human resource availability on the management of visitor access. At the same time, official records showed an increase in public use, rising from 50 visitors in 2020 to 3,193 in 2025. It is concluded that the estimated limits should serve as dynamic management support parameters—coupled with periodic monitoring of environmental, social, and operational conditions—to reconcile the expansion of public use with the conservation objectives of the Açu National Forest (FLONA).
