Strategic Environmental Assessment

A "Strategic Environmental Assessment" (SEA) is being led by Professor Bob Scholes of the University of the Witwatersrand. The purpose of the SEA is to make informed decision about fracking, if the reserves of shale gas in the central Karoo prove viable. So the challenge to us, as citizen scientists, is to accumulate as much data as we can for all our ADU atlas projects, both for the birds and for all the groups of species in the Virtual Museum (see Data collected up to about the middle of next year will help influence decisions made about where fracking can take place, and about how it is done. The South African government has already taken the decision to go ahead. Other countries have simply gone ahead without doing a proper biodiversity baseline study. At least we have been given an opportunity to influence the where and the how.

For the bird atlas, the objective is going to be to get as much of this area to "foundational" coverage of four checklists per pentad. In other words, we don't only want to target the pentads which are not yet visited, we also want to target those with one, two or three pentads, and get them to a minimum of four checklists on the coverage map, and turn them GREEN. It is the SEA-GREEN challenge. But the more data we get for any pentad within this region the better; for those pentads for which we already havelots of checklists, we have a baseline against which to measure future change in species composition. This needs lots of checklists!
