The growth in ungulate populations and the enhanced viewing opportunities they provide in many national parks, a mixed blessing to park managers, has been viewed positively by most park visitors. Visitors, long the major constituency of parks, have played a major role in the way ungulates are managed. I trace the history of the relationships between visitors and ungulates in parks and provide examples of how visitors have influenced ungulate management policies. Today, although public influence on ungulate management seems to be greater than ever, the public has a poor understanding of park management actions. Park interpretive programs can be used to address this problem.
