A History of Forest Entomology in the Intermountain and Rocky Mountain Areas, 1901-1982
Author: Malcolm M. Furniss

ISBN:
Category : Forest insects
Languages : en
Pages : 48
Book Description
This account spans the time from A.D. Hopkins' trip to the Black Hills, SD, in 1901 to my retirement in 1982. The focus is on personnel and the work of the Division of Forest Insect Investigations, USDA, and the Forest Service experiment stations in the Rocky Mountain and Intermountain areas. Information for the Intermountain and Northern Rocky Mountain station areas is derived from my experience there and as chairman of the history committee of the Western Forest Insect Work Conference (WFIWC). Information on the Rocky Mountain and Southwestern station areas came primarily from the WFIWC archives, University of Idaho, and from retired forest entomologists.
