During the 1980s, reforestation programs using exotic species (Pinus spp.) were established in the páramo ecosystem of Ecuador. The aims of this study were: (1) to compare the natural regeneration between pine plantations (Pi) and natural grassland (NG) across an elevational gradient and (2) to identify the attributes of Pi and soil properties that were influencing herbaceous and woody plant composition and their plant cover. In total, six independent Pinus patula (Schltdl. & Cham. plantations (two per each elevation) were selected and distributed in an elevational range (3200–3400, 3400–3600, 3600–3800 m a.s.l.). Adjacent to Pi, plots in NG were established for recording natural regeneration. Both, namely the attributes and the soil samples, were measured in Pi. The results showed that natural regeneration differs significantly between both types of vegetation. As expected, NG holds more plant diversity than Pi; the elevational range showed a clear tendency that there was more herbaceous richness when elevation range increases, while the opposite was found for woody species. Moreover, attributes of Pi influenced herbaceous and woody vegetation, when saturated hydraulic conductivity (Ksat) in the soil, basal area (BA) and canopy density (CD) increased, herbaceous species richness and its cover decreseased; and when Ksat and the acidity in the soil increased, woody plants richness and its cover decreased. The plantations have facilitated the establishment of shade tolerant species. More studies are needed to evaluate if removal with adequate management of pine plantations can improve the restoration and conservation of the native vegetation of the páramo ecosystem.

The páramo, a collection of Neotropical alpine ecosystems, plays a prominent role in ecosystem services (ESs), providing water supply and regulation, conservation of biodiversity, and carbon storage in soil. The establishment of pine plantations for carbon sequestration and wood production has recently raised questions concerning the possible impact on the páramo’s ES. This study identifies the main stakeholders in this field and compares and contrasts their perceptions of the impact of pine plantations on the páramo’s ES, because the disparity among stakeholders’ perceptions must be addressed to achieve sustainable management. The data were gathered using 56 semi-structured interviews and were qualitatively analyzed. The results show that the main stakeholder groups (landowners, local government officials, foresters, and nature conservationists) acknowledge the important ES of the plantations. The perception of plantation impact varies among and within stakeholder groups, however, on specific functions, such as water provision, carbon storage, erosion prevention, and habitat function for wildlife and natural vegetation. Consideration and integration of these perceptions can help policy makers and organizations develop sustainable policies for the future management of the páramo ecosystem.
