Bats are among the least understood and most loathed mammals on the planet. Myth and legend paint them as cruel vampires that would not hesitate to drink all the blood from their innocent victims. While it is true that three blood-sucking species exist in the world, they are not as cruel as myths make them seem, and there are many other species that have important roles in their ecosystems. In rainforests in particular, bats control insect populations, serve as pollinators and seed dispersers for numerous plant species, and in some cases regulate populations of small vertebrates, providing balance to the intricate web of life in the forest.
Bolivia is one of the countries with the highest levels of biodiversity in the world, a fact which is evident in the number of mammal species that exist. This charismatic group of fauna includes 125 species of bat, which is close to half of the total mammal species in the country. Madidi National Park, a protected area of international importance and a jewel of biodiversity, spans numerous ecological zones, from permafrost to Amazonian forest, and is home to more than 90 bat species.
Bats are crucial for all the ecosystems they inhabit, yet we still know far too little about the species found in this region. We continue to identify new species in the Park, but information about their natural history and ecology is still very limited. Most of the species of bats in Madidi were recorded through a combination of sampling methods, including the use of mist nets at ground and canopy level complemented by acoustic monitoring. This mix of sampling methods provides a more complete view of the species present in a particular ecosystem. Even though ACA-Bolivia has made great progress in recording this region’s bat species, there are still many ecosystems and forest types to be sampled. Further study will certainly increase the known diversity of bats in this protected area and will make evident the great intrinsic and ecological value of these species while adding to our ability to conserve this magnificent landscape.
