Before the organization of the School of Forestry and Conservation in 1927, no courses in forest zoology were offered, and research concerned with the management or control of forest animals was of a casual nature. Increasing recognition of the importance of animal life in the forest led to demands in this field which have been met through courses and research in the School.
In teaching and research it is necessary to consider forest animals not only as individual entities, but also in their relation to each other and to the plants with which they are associated. Thus, forest zoology requires an ecological approach, and courses in this field are strongly influenced by this requirement. They include a general course in forest zoology, courses in the economic relations and management of forest animals, pathology of forest animals, range management, forest entomology, and forest ecology. These courses provide for the needs of students who expect to enter the field of timber production or utilization, those in the general field of wildland management, and those who plan to enter some field of forest zoology. Although a student may elect several courses in forest zoology as an undergraduate, specialization involves graduate study.
Considerable research has been conducted by staff members and graduate students. Attention was given by Professor Howard M. Wight to the ecology and management of the pheasant and to the animals with which it is associated in southern Michigan. Some of the results of this work have been published. A study of the Hungarian partridge and one of the biology and management of the cottontail rabbit were made.
In the field of animal pathology Assistant Professor Earl C. O'Roke has published the results of his studies concerning the Leucocytozoon disease of ducks and the diseases of deer, including those caused by lungworms and other organisms associated with winter mortality.
In the field of forest entomology numerous studies have been carried on by Samuel A. Graham, Professor of Economic Zoology, and have been concerned with defoliators, especially the ecology Page 1112and control of the spruce budworm on pine, the effects of walking-stick insects on forest areas, the larch sawfly, and the larch casebearer. Much time has been devoted to searching for control measures for white grubs in forest plantations.
The research work in forest zoology has been supported in part by regular University funds, but financial and other support has also been given by the State Department of Conservation, the Izaak Walton League of America, the Sporting Arms and Ammunition Manufacturers Association, the United States Forest Service, the Bureau of Entomology, and the United States Department of Agriculture. Especially close relationship is maintained with the Forest Service and with the Bureau of Entomology through collaboration arrangements for an official station here.
