Pine plantations have negatively impacted biodiversity and the establishment of native flora in Ecuador. We evaluated whether needle removal facilitates the establishment of Oreocallis grandiflora in a plantation in the southern part of the country; we conducted direct seeding in plots with and without needles. Our results showed that removal had no statistically significant effect on emergence (p > 0.05), but it did affect survival (p < 0.0001). After 22 weeks, we recorded >86% survival in plots without needles and 7% in those with needles. Two years later, we observed significant growth, although survival was 82% and 5%, respectively. We conclude that direct seeding is viable, but recommend monthly needle removal during the first few months to ensure successful establishment.
