Bird atlas project sequel flies

With its publication in 1997, the landmark Southern African Bird Atlas Project (SABAP1) created the biggest biodiversity database in Africa. The sequel project, SABAP2, launched on 28 June in Cape Town, hopes to do much the same.

It will gather updated, finer-scale distribution data through professional and public participation, providing a "second snapshot" of bird distribution in South Africa, Swaziland and Lesotho.

The project is a partnership between UCT's Avian Demography Unit (Professor Les Underhill is the project leader), BirdLife South Africa and The South African National Biodiversity Institute. Their work will add to the understanding of the distribution and abundance of bird species across the subcontinent.

But it's the "citizen scientists" that play a large role: the bird clubs, amateur ornithologists and landowners who are the project's eyes and ears. They will record species distribution across more than 2 000 grid cells.

This data provides scientists with insights into how our environment is changing, changes that place huge pressure on birds. And it's birds, which can be "pulse monitored", that show how and where that change is manifesting.

"They fly," says the ADU's James Harrison. "They're quick to respond to changes, providing invaluable warnings and pointers."

"Rome is actually burning," adds Dr Phoebe Barnard, co-ordinator of SANBI's Birds and Environmental Change Programme. "We live in a time of unprecedented environmental change."
