Barra Scar

I may have heard the answer before, but....

What caused that huge scar on the hill at the entrance to the lagoon at Barra de Potosi.....the light-coloured "new growth" area? Was it a British Columbia-style forest clearcut done many years ago? And if so, why does the new growth appear to be a uniformly different species from the original old-growth?

Just wondering....
