Interesting how perspectives change.
Earlier in life I considered sheep to be peacefull animals, kind of living lawn mowers, calm decoration of landscapes and of course very tasty food and great deliverers of woool for my favorite jumpers.
Yet, today with all the knowledge I acquired about watershed management I see them as transformers and destroyers of landscapes, esp. keeping back forests were they are needed, causing erosion and flood and deterioation.
Back to the picture: Wonderful how you show the movement pattern. I was not aware that sheep in the middle of a herd might move much slower that the sheep around them. Very interesting. Thank you
