Forming part of the Ethiopian Highlands in Southern Ethiopia is the Liben Plain, an Important Bird and Biodiversity Area. These plains hold one of only two known populations of the Critically Endangered Liben Lark Heteromirafra archeri, one of the oldest species of lark in the world, with only 50 to 100 individuals surviving today. Over the years, the Liben Plain has seen numerous human pressures. Population growth, overgrazing, in addition to drought and soil erosion among others, has meant that only a small fraction of the grasslands remain, much of it degraded. In turn, this has led to the fragmentation of the Liben Lark’s habitat, splitting populations from each other and putting additional pressure on this bird.
