Vegetation and Climate History of the Harenna Forest (Bale Mountains, Ethiopia) in the Holocene

详细

The results of spore-pollen analysis and analysis of non-pollen palynomorphs of the Katcha zoogenic deposit, located in the Harenna Forest (Bale Mountains National Park, Ethiopia) are presented. It is revealed that bamboo monodominant communities have inhabited areas at altitudes of 2700–2800 m above sea level for at least the past 6500 years. A trend towards a decrease in bamboo communities due to climate aridization in the last 5000 years has been revealed. It is established that active human impact on these ecosystems began 1000 years ago.
