Páramo, high-elevation tundra ecosystem, is considered as an important biodiversity hotspot. Páramo is a fragile system due to its slow recovery rate after disturbance such as wildfire. Nowadays, páramo in central Costa Rica is under threat from more potential fires due to climate warming. Long-term hydroclimate reconstructions for this region will enable us to better understand the past climate change, its impact on high elevation vegetation and fire activities, and to better conserve páramo.
