Recruitment from seeds is a fundamental process for regeneration. Germination and seedling growth are especially important for trees' conservation. Gomortega keule (queule) is an endemic and endangered Chilean evergreen tree growing in a small area within a global hotspot of biodiversity. Germination and seedling production in this species are not well understood, but presumed very limited. Populations are highly fragmented and threatened by land use change, especially forestry plantations, and fire damages. This study monitored G. keule seedlings in four sites over three years, recording the emergence and survival of seedlings in 24 plots located in four sites within patches of native vegetation surrounded by plantations of exotic forest trees. Seedling emergence occurred during springtime (October - December), lasting 40-70 days. After emergence, there was a sharp decline in seedling survival; 21.3% survived the first three months. Seedlings died more often in late spring. We confirmed that seedling emergence for G. keule is occurring. However, there is an absence of older seedlings and saplings. More studies are needed on the causes of death. Seedling survival in this endangered tree is essential for its long-term conservation and forest restoration.
