Frailejón
The frailejón plant (Rockstroh, 2024)
The frailejón, plants of the genus Espeletia, is a quintessential plant in Andean high-altitude paramo ecosystems. The frailejón plays a fundamental role in hydrological regulation. With an extended root matrix and dense, trichome-covered leaves, its morphological features are highly effective in intercepting the atmospheric moisture from fog and rainfall (Rockstroh, 2024). This intercepted water is allowed to run down the stem and infiltrate the soil to recharge the subterranean aquifers that feed regional river systems. Paramos are usually referred to as “water factories” since they supply as much as 85% of the potable water in Colombia, aided by its sponge like features contributing to greater water capture (Baruffol, 2020).
Beyond water capture, frailejones act as ecosystem engineers, structurally modifying their environment to form microhabitats. The retention of large leaves along the stem provides critical shelter and nesting resources for a diversity of high-altitude fauna, including birds, insects, and small mammals (WCS Colombia, n.d.). This capacity to shape biotic communities underlines its identification as a potential “key to restoring” degraded páramos. Indeed, efforts in Ecuador have so far established the propagation and replanting of native frailejón species as a primary methodology for post-disturbance recovery, such as following wildfires and erosion events (Mongabay, 2025).
This is even more crucial when considering the global climate crisis and its impact on the frailejón. Páramos are among the world's largest carbon sinks primarily because of the peat stored in the soil and the amount of carbon that is stored there. As such, a healthy population of frailejón contributes to the continued health and sustainability of these carbon reservoirs (The Nature Conservancy, 2023). However, this also contributes to the vulnerability of the genus itself. With both climate change and human activities such as fires putting the slow growing and long-lived organisms at risk, the potential consequences of loss of mature individuals can be severe and have lasting effects on the ecosystems in which they live (Mongabay, 2025) (WCS Colombia, n.d.). Therefore, it would be impossible to imagine the páramo ecosystem without the frailejón, as it serves a fundamental role in generating hydrology in the area, a facilitator of biodiversity found nowhere else in the world, and a protector of large amounts of carbon. Because of this, protecting and restoring populations of frailejón is more than just conservation, it is an investment in the hydrological security and climate resilience of the Andean countries.
