Biological corridors, such as the "Jaguar Corridor" and the "Path of the Anacondas", connect areas of natural systems and are essential to guarantee the protection of biodiversity and the supply of ecosystem services.
The principle of conserving biodiversity exclusively with protected areas was reevaluated some years ago due to the emphasis given on connecting areas of natural ecosystems through corridors1. In Colombia, the variety of landscapes requires extensive biological corridors that are based on focal species and distributed in a way that all of the territory is covered: from the Pacific region, the Andes mountain ranges and valleys, to the plains of the Orinoquia and the Amazon. In this sense, the protection of keystone species ensures that most of the territory is included, but also that the associated biota is conserved.
Connectivity is indispensable in order to maintain gene flow between populations and also to guarantee the ecosystem services provided by those natural areas. For example, corridors may positively affect the regulation of water cycles in places like the Amazon basin, a region in which the incorporation of conservation strategies to indigenous territories is essential. The most common tool in creating connectivity is the use of biological corridors2, especially those that are based on species with large sizes and territories, low population densities, great popularity within the general public, and high sensitivity to human activities3-6.
