FOREWORD 
Recent, rapid advancements in science and 
technology should encourage those responsible 
for proper husbandry and stewardsip of the 
Nation’s nearly 1 billion acres of range and 
wildlife habitat resource. There is considerable 
knowledge of both the physical and biological 
processes governing the many range environ- 
ments. New guides which are essential for wise 
management are being developed. 
From time to time, Forest Service scientists 
have discussed, in national workshops, current 
information pertinent to a broad topic that is 
within their area of responsibility. Such meet- 
ings provide opportunities for Forest Service 
scientists to become more fully aware of recent 
technology and new scientific knowledge. 
The first workshop in range and wildlife 
habitat research and management was held 30 
years ago to consider planning, preparation, 
and publication of research results. A second 
was concerned with range seeding and noxious 
plant control. In 1962, a symposium on Range 
Research Methods explored vegetation mea- 
surement and sampling, measurement and 
evaluation of range use by livestock and game, 
and design and conduct of grazing experi- 
ments. Other regional conferences and meet- 
ings have enabled Forest Service personnel to 
review and update their philosophy and knowl- 
edge to meet their responsibility in range and 
habitat management in its broadest context. 
The fourth conference, entitled “Range and 
Wildlife Habitat Evaluation—A Research Sym- 
posium,” encompasses six sessions. 
1. Forage evaluation for livestock and 
wildlife (four sessions). 
2. Remote sensing in range and wildlife 
habitat evaluation. 
3. Status, applications, and challenges of 
range and wildlife habitat ecology. 
Scientists from the Forest Service and other 
Federal and State agencies and from universi- 
ties contributed to the conference. 
Note: It is the purpose of this publication to 
make available the papers presented at the 
conference to as extensive an audience as pos- 
sible; except for editing, the individual papers 
are essentially as presented. Accordingly, the 
material represents the views of the individuals 
and not necessarily those of the Forest Service.
