The instructor was Dr. Eugene Bakko.Ten porcupines were observed within the park over a period of two weeks. Generalizations and correlations were difficult to make since behavior varied greatly among individuals. Damage to trees in the area was noted. There was no visible evidence of harm done by porcupines to red pines which has been a problem in the late 1960's.Report
