A field of glyphosate-burned gorse (Ulex europaeus) is pictured in Cogua, Cundinamarca Department, Colombia, on October 9, 2026. The thorny gorse shrub (Ulex europaeus), introduced to Colombia from Europe in the mid-20th century, has spread from Bogota into Andean ecosystems and high-altitude paramos, unique tropical mountain wetlands known for their water-storage capacity. Highly flammable, the invasive plant fuels wildfires that have been exacerbated by the current El Niño climate phenomenon, described by meteorological agencies as one of the strongest on record.
