Species of the Pteridium genus, known commonly as brackens, are considered invasive, limiting the late succession and diversity of tree species. However, contrasting reports state that they are a facilitating agent for woody species that, once established, favor the arrival of other taxa and facilitate restoration of seedling expression under different mowing frequencies of Pteridium esculentum subsp. arachnoideum x Pteridium esculentum subsp. campestre. The aim of this study is to evaluate the influence of this fern in the establishment and growth of seedlings on an abandoned bracken-dominated pasture in the area called Golconda located in the National Natural Park Serranía de Los Yariguíes in the Colombian Andes. For this, nine plots of 25 m2 were established in a completely randomized experimental design with three treatments: Treatment 1 is the control with no intervention (CP), treatment 2 includes one mowing applied at the beginning of the experiment (Fern mowing FM-I), and treatment 3 includes mowing every two months (Fern mowing FM-2M) for an eight-month period. In each plot, all seedlings were marked, and their height (cm), coverage (cm2), and survival were recorded. This work concludes that in the study area, the permanent presence (CP) of the fern favored the diversity and growth of species. However, the FM-2M treatment is considered a repopulation management option approach due to its effects on seedling abundance, given the negative results in diversity, growth, and survival.
