Forest management meeting at Big Springs, Idaho National Forest. No names are listed, but Lyle Watts may possibly be in the front row, second from the right.
Rangers with Lyle Watts, center with hand on hip, examine lysimeters in San Dimas Experimental Forest, California. A lysimeter measures the amount of water lost to evapotranspiration in a certain area of soil. Evapotranspiration amounts are the sum of the amounts of water lost through evaporation and transpiration of the plants.
