. Research for tomorrow's forests : 1983 research accomplishments. --. Forests and forestry Research United States. Ferreting Out Information To Manage the Southern Pine Beetle Recent infestations of the southern pine beetle prompted scientists in the Forest Service to develop a series of computer-based mathematical models that describe beetle population dynam- ics, stand growth, and utilization of beetle-killed timber. The models also rated stand hazard and evaluated the impact of the infestation. Access to these models was limited to research scientists because of the manner in which they were originally developed. To overcome this problem and make the models accessible to forest managers, Southern Station scientists and re- searchers at Texas A & M University developed a computer program called FERRET. FERRET is an interactive system of questions and answers that leads users to the most appropriate model or mod- els for their needs. At the present time, 28 models are available for use. Through FERRET, users have access to information for decisionmaking based on pest population dynamics, host dy- namics, impact, overall management objectives, ownership, land use patterns, and user capabilities. FERRET is useful for long-term resource planning as well as for crises. Likewise, it provides a means of eval- uating management strategies and treatment tactics. Organizations cur- rently using FERRET include forest industry, State forestry organizations, the Forest Service, and other Federal A user interacts with the computer by punching in answers to questions about his timber stand and its beetle infestation. 24.
