Montane ecosystems in South America harbor high levels of endemism typically with species that are often threatened. Here we investigated fruit and seed morphology, germination, and early growth parameters of Crinodendron brasiliense, an endangered and narrow endemic tree species of subtropical montane cloud forests in Southern Brazil. We obtained fruit and seed size and shape, number of lobes and number of seeds per fruit and evaluated germination and early growth parameters in a greenhouse. We tested the effect of different container types and parent plant on seed morphology, germination, and early growth. We also tested whether thermal scarification would improve germination rates. We showed that parent plant significantly influenced fruit and seed morphology as well as early growth rates. The germination rate of the species was extremely low (0.003–0.004%), which may be one important underlying cause of its small population size and restricted distribution. Thermal scarification was ineffective to improve the germination of seeds. Unexpectedly, container type significantly affected germination success, as seeds in trays germinated faster and in higher rates than seeds planted in seedbeds. Such result suggests a higher soil moisture could improve germination success. Our study is the first documented propagation of the species and provides essential aspects on the reproductive biology and early development of Crinodendron brasiliense. We highlight the urgent need for further research and collaborative conservation initiatives to prevent the extinction of this species.

Florestas altomontanas nebulares são importantes ecossistemas devido ao alto endemismo de espécies e funções ecológicas vitais. Contudo, encontram-se altamente vulneráveis à mudança climática. Crinodendron brasiliensis é uma árvore endêmica da Serra Geral e atualmente classificada como ameaçada de extinção. Sendo assim, este estudo buscou investigar o padrão de dinâmica demográfica e crescimento de indivíduos de Crinodendron brasiliense em seu habitat natural. O estudo foi realizado em duas áreas de floresta nebular no Parque Nacional de São Joaquim, em Urubici, Santa Catarina. Para o estudo de dinâmica demográfica, foram amostrados indivíduos (DAP ≥ 5 cm) em 20 parcelas de 10x10, distribuídas em um transecto (20x100m). As taxas demográficas de mortalidade, recrutamento, ganho e perda em área basal, mudança líquida e rotatividade foram avaliadas. Para o estudo de crescimento, foram instalados dendrômetros radiais automáticos em cinco indivíduos em outro fragmento de floresta nebular, também no PARNA de São Joaquim, e um termo-higrômetro foi instalado para monitorar a temperatura do ar em área aberta adjacente. Em geral, a dinâmica demográfica pode ser resumida por mudança líquida no número de indivíduos (-1,94%.ano-1) e estabilidade na mudança líquida em área basal (-0,06%.ano-1). Os dendrômetros indicaram baixo incremento acumulado, com crescimento concentrado de janeiro a março. Conclui-se que os indivíduos monitorados apresentam um baixo incremento, influenciado pela temperatura, e estão em fase de auto-desbaste.
