Beal, Superintendent Great Smoky Mountains National Park It is a distinct pleasure and genuine privilege for me to welcome you to Great Smoky Mountains National Park on the occasion of the Fifth Annual Uplands Areas Research meeting. Actually, it is a little incongruous, because I am a new arrival, having reported for duty about six months ago, and many of you have been carrying out scientific investigations here for a long time. However, I do share your interest and enthusiasm concerning the natural resources of this park and region, and personally claim acquaintance with some of them based on a previous tour of duty here from 1969 to 1972. I am pleased to be back here, and gratified by your presence here today. This meeting is a learning and sharing occasion and I know we will benefit from the exchange. Let me briefly outline some of the concerns that park managers have that relate to scientific research. First, we welcome new knowledge and continuing investigations, but must encourage the development of increased professional objectivity. Emphasis must be placed upon identifying alternatives and consequences rather than upon advocacy of specific courses of action or "prescriptions." Humility is required of all of us . Tcday science has better methods , equipment and knowledge than ever before, but we must also remember that the "best" of the past has at times led us astray. Our society and the conservation community have at times: 1. Favored prey species to the detriment (even extirpation or extinction) of predators. 2. Favored introduced or exotic species at the expense of native life forms . 3. Favored visitors and their activities at the price of resource degradation. 4. Utilized persistent pesticides in attempts to save threatened resources, and ended up with a "cure" worse than the threat. Now it is perhaps timely to suggest that we must guard against being so zealous in preservation of resources that we lose sight of the park visitor's needs . The loss of our constituency of park users could ultimately result in the loss of the parks . 1 Balance and perspective are needed in all our programs. Balance that is consistent with our legal (and sometimes conflicting) mandates, and balance which observes dual objectives of preservation and use in the National Park System. We must recognize that scientists can often wait as long as necessary for all the data to come in, and to develop "final" or definitive answers, but policy makers and managers
