Population structure of Butia catarinensis in the Restinga vegetation of Gravatá Beach, Laguna, Santa Catarina

Abstract

This study investigated the population structure of the endemic species Butia catarinensis in the region of Laguna, Santa Catarina. This palm is essential for the ecological balance of coastal ecosystems, particularly in the restinga formations, and plays an important role for local communities, who use its fruits and leaves in food and handicrafts. However, the species faces various threats, such as deforestation, unplanned urbanization, wildfires, and the invasion of exotic species, which compromises its natural regeneration. The research was conducted at Gravatá Beach using systematic sampling, analyzing age distribution, spatial patterns, and factors affecting the species' development. The results indicate ecological patterns influenced by environmental and anthropic conditions, providing insights for the planning of sustainable management strategies. The study emphasizes the importance of conserving the species and implementing public policies that ensure its preservation, highlighting its ecological, socioeconomic, and cultural value for the region.
