An unprotected vulnerable relict subtropical conifer-: Its forests, populations, growth and endangerment by invasive alien plant species in China.

Relict subtropical coniferous forests in China face severe fragmentation, resulting in declining populations, and some are under significant threat from invasive alien species. Despite the crucial importance of understanding forest dynamics, knowledge gaps persist, particularly regarding the impact of invasive plants on vulnerable natives like . In this study, we investigated the impact of invasive plants on the regeneration of forests dominated by .

Forest characteristics, population structure and growth trends of threatened relict in China.

is a relict evergreen coniferous tree species in Pinaceae endemic to China. tree numbers have greatly decreased due to deforestation, over-utilization and habitat degradation. Here we clarify community types, structure, species diversity, seedling recruitments and growth trends.
