The main threat to the north-eastern population of the blossomcrown is the loss of its habitat to coca and marijuana plantations. In the past, the Colombian authorities have sought to combat these plantations by spraying the slopes with herbicide, simply creating a new problem for the blossomcrown (4).
Human immigration to the area, beginning in the 1950s, has also become a problem, as it results in expansion of agriculture areas, for produce such as coffee and livestock, logging, burning, and the planting of exotic trees, such as pine. As a result of these activities, only 15 percent of the original forest vegetation remains in the Sierra Nevada de Santa Marta (4).
On the eastern slope of the Central Andes, home to the population of A. f. berlepschi, much of the original habitat has also been cleared for agriculture since the 1950s. Cattle-grazing and plantations growing coffee, sugarcane, banana, potatoes and beans are all contributors to this habitat loss. Today, only scattered patches of mature secondary forest remain, and natural vegetation cover has been reduced to just 15 percent of what it once was (4).
