Eucalyptus Plantations Fail to Replace Native Forests for Birds
A study of eucalyptus plantations in Turkey found they support far fewer bird species than natural broadleaf forests, suggesting that industrial tree farming cannot offset biodiversity loss from native forest conversion. The finding challenges a common assumption in Mediterranean regions where fast-growing eucalyptus is planted as a 'green' alternative to deforestation.

The possibility that new habitats resulting from silvicultural practices in Mediterranean coastal countries may have negative ecological impacts on existing biodiversity has often not been taken into account. For this reason, this study was carried out to determine the amount and diversity of bird species (breeding) in eucalyptus plantations. The study was carried out in eucalyptus plantations in a region located in Tarsus district of Mersin province in southern Turkey. Birds of 3 different age categories were observed at 22 points in the selected region. Vegetation parameters were measured by counting along transects 50 meters long and 10 meters wide in 4 main directions from the center of the points. As a result of this study, a total of 17 bird species were identified in these areas and it was concluded that most of the bird species were underrepresented compared to the broadleaf forests. Eucalyptus plantations are far from being a supplementary forest habitat for bird species in the current region and provide an inadequate habitat. Birds that occupy these plantations are likely to benefit from an extended rotation time and retention of understory vegetation.
