The objectives of this study were to (a) determine preservice educators' perceptions of forest health, (b) define the experiences which may have influenced their understanding, and (c) identify the approaches they might use to convey forest health information. Twelve interviews were conducted with preservice science and agriculture education students at the University of Florida who are likely to teach about forest ecosystems. Results suggest that many respondents understand ecosystem function, the importance of insects, and the effects of invasive species. Most respondents demonstrated little knowledge of diseases, fungi, and appropriate ways to use the analogy of human health. Several findings suggest these perceptions are related to the types of experiences respondents had with forests.
