Abstract: The overabundance of deer across the United States is a widely documented phenomenon and southwestern Virginia is no exception. I examined the effect of deer herbivory on the reproductive phenology of a woodland herb, Campanulastrum americanum . Flowering time is essential in the life history schedule of C. americanum because of its direct influence on the offspring's season of germination. Since flowering requires a vernalization period, fall germinating seedlings flower as annuals while spring germinating seedlings flower as biennials. Additionally, maternal light environment influences season of germination, such that plants in higher light environments flower earlier. Thus, any changes in the survival, recovery and reproductive phenology of the maternal plant due to browsing have the potential to impact the life history schedules of the offspring, and this impact may vary across light environments. I employed a fully-crossed design with three herbivory treatments: deer, simulated and control and two light conditions: light-gap and shaded understory. I found that herbivory significantly affected the growth and survival of Campanulastrum americanum, and this impact is uneven within the two light environments. Light-gap plants were more likely to be eaten and were eaten earlier than shade plants. Browsed plants in light-gaps also had lower survival than browsed plants in the shade. Moreover, reproductive phenology was greatly shaped by deer herbivory. Eaten plants not only flowered later, but had fewer total flowers. The shift was so dramatic that deer-browsed plants in the sun have similar flowering patterns as control plants in the shade. This suggests that deer herbivory will shift the ratio of annuals to biennials and would enhance the production of biennials in subsequent years.
