I was impressed on the descent into Chile at how lush and green everything was, how mild the climate, fields full of buttercups and daisies and broods cows. Still in a forest-clearing stage, but also plantations of pines, but saw none of large size. fots of lumber trucks on their way to Argentina (or Brazil?). Gave a talk on the 5th, then a field trip to visit Murria's study area north of Valdivia (24km NVE), accompanied by chofer, Suz, Feito, Oscar, and Paterniervese. The University owns a 65-ha parcel of forest + meadow with a 12x12 10-m grid in each. They have been trapping there for several years, the traps apparently run by Pedro, a
