Claudia, I am aware of the blog and have been discussing the topic with Tony Whitten. The way I read Tony's input is that it is a concerned personal reflection rather than a scientifically docummented empirical fact. I assume we are both waiting for some evidence to shed some light on the role of goats in ecosystem dynamics and pasture resources. Until then all we can do is voice our personal views. Perhaps the Bank would like to fund an extensive comparative study to investigate the role of goat grazing pressure in different ecosystems in Mongolia?
