Many people ask us why we leave old fences standing around. The old fence posts in this picture appeared to our eyes for the first time last year, during the very long and dry season that we had. They are standing in a saline lake (salina) and if we could ask them I am sure that they would have many stories to tell. Right now they are being used daily by birds (in this case by large-billed terns (Phaetusa simplex, trinta-reis-grande)) as roosting and resting opportunity. So from our point of view old posts open a new micro-habitat that soon will be colonized by many different creatures, from fungi to insects, birds and others !
