This big savanna at a c 800m elevation on poor white sand soil has been severely altered by human hand. Rice paddies and cattle grazing dominates the landscape. However, there are some wetlands, grass areas, dry bushy scrub, as well as the gallery forest of Tingana reserve and the forest covered Morro de calzada hill. All in all this makes this area very rich in species that are often hard to find elsewhere in Peru, why a trip down to the savanna from Abra Patricia is very rewarding for the total species list.
