Researchers investigate decline in forest-birds

Forest-dwelling bird species are disappearing from some of South Africa's indigenous forests, with forest birds in the Eastern Cape being the most affected.

A new study, published in Bird Conservation International recently, showed that the ranges of 28 of South Africa's 57 forest-dwelling bird species were declining, while those of 22 species were increasing and seven remained stable.

The findings are based on 25 years of citizen science data collected by the Southern African Bird Atlas Project. The data can be used to indicate the conservation status of a species, depending on its known range and how it is changing. The first survey took place from 1987 to 1992, and the second survey started in 2007 and is ongoing.

Researchers from Stellenbosch University (SU) and the Department of Environmental Affairs used data on 57 forest-dwelling species to investigate links between deforestation, species characteristics and range declines for these species over the last 20 years.
