Richness of ferns and lycophytes from Tijuca National Park, an urban forest

Tijuca National Park (TNP), covering 3.5% of Rio de Janeiro, harbors approximately 38.5% of the state's known ferns and lycophytes, with 254 taxa across 26 families and 83 genera. This study reveals that precipitation during the wettest month is a critical climatic factor influencing species richness and composition within this Atlantic Rainforest fragment. By analyzing spatial distribution patterns in relation to environmental variables, researchers identified key factors shaping biodiversity in urban forests. The findings underscore the importance of climate in determining floristic diversity, offering insights for conservation strategies in fragmented rainforests.
